The numbered disks shown are placed in a box and one disk is selected at random. Find the probability

Answers

Answer 1

The probability of selecting a 2 given that a blue disk is selected is 1/8, or 0.125.

What is the calculation for this?

1. Let's calculate the probability of selecting a blue disk

We can select a blue disk with number 2, 6 or 8 out of a total of 8 disks, it means that the probability of selecting a blue disk is = 3/8

2. Let's calculate the probability of selecting the blue disk labeled with number 2 =

We can select the blue disk labeled with number 2 out of three blue disks, it means that the probability of selecting the blue disk labeled with number 2 is = 1 /3

3. These are dependent events because the fact that we select the disk labeled with number 2, depends on selecting a blue disk before, thus:

Probability of selecting a 2 given that a blue disk is selected =

3/8 x  1/3 = 3/24 = 1/8

Thus,it is correct to state that the probability of selecting a 2 given that a blue disk is selected is 1/8, or 0.125.

Amy is planning an event for her company where at least 1,640 guests are expected to attend. She is reserving rooms at a large hotel-convention center.

Select the inequality that Amy could use to determine how many of each type of room she will need to reserve. a. 30x + 139y<1640 b. 30x + 139y>1640 c. 30y + 139x<1640 d. 30y + 139x>1640

Answers

The inequality states that the sum of the number of conference rooms and ballrooms should be greater than the number of guests, so that all the guests can be accommodated. The correct answer is d. 30y + 139x>1640.

What is inequality?

It is usually written using symbols such as “<”, “>”, “≤”, and “≥”, where one side of the expression is greater than, less than, or equal to the other side.

This is the appropriate inequality to determine how many of each type of room Amy will need to reserve because it expresses the total number of guests (1,640) that must be accounted for in the total number of conference rooms (30y) and ballrooms (139x).

To solve the inequality, Amy can start by assuming the number of conference rooms (y) she will need to reserve.

If she decides to reserve 10 conference rooms, the inequality will become 30(10) + 139x > 1640.

This can be simplified to 1390x > 1640 - 300, which reduces to x > 7.64. This means that Amy will need to reserve at least 8 ballrooms to accommodate all 1,640 guests.

whats angle A pls help

Answers

Answer:

x = 19.6

Step-by-step explanation:

The sum of the angles of a triangle is 180.

<A + <B+ < C = 180

x + 5x + 4x - 16 = 180

Combine like terms.

10x-16=180

Add 16 to each side.

10x-16+16 = 180+16

10x = 196

Divide each side by 10.

10x/10 = 196/10

x = 19.6

Answer :

Angle A = 19.6°

Step-by-step explanation :

According to the question It is given that,

Angle A = x Angle B = 5x Angle C = 4x - 16

We will apply angle sum property in the question.

Angle sum property states that sum of all the angles of triangle is 180°

[tex]\: :\implies [/tex] ∠A + ∠B + ∠ C = 180

[tex]\: :\implies [/tex] x + 5x + 4x - 16 = 180

[tex]\: :\implies [/tex] 10x - 16 = 180

[tex]\: :\implies [/tex] 10x = 180 + 16

[tex]\: :\implies [/tex] 10x = 196

What is right angle triangle?

The term "right-angled triangle" refers to any triangle with an internal angle that is either a right angle or 90 degrees in value. The right triangle or the 90-degree triangle are other names for this triangle because of this. Right triangles have "opposite" and "adjacent" sides, which refer to the sides that are across from and next to respective angles, respectively. When a right triangle is formed, the hypotenuse is its longest side.

We can consider the flagpole, the ground, and the rope as forming a right triangle. The angle between the flagpole and the rope is 90 degrees, and the angle between the rope and the ground is 35 degrees. Therefore, the angle between the flagpole and the ground is 90 - 35 = 55 degrees.

Let's call the length of the rope "r". We can use the trigonometric function tangent to find r:

tan(35°) = opposite/adjacent = r/20

Multiplying both sides by 20, we get:

r = 20 tan(35°)

Using a calculator, we get:

r ≈ 11.9 feet

Therefore, the length of the rope is approximately 11.9 feet.

Length is a measure of the size or distance of an object or space in one dimension, usually referring to the longest dimension of an object. It is typically measured in units such as inches, meters, or feet.

What is triangle?

In geometry, a triangle is a closed two-dimensional shape that is formed by connecting three non-collinear points with straight line segments. The line segments are called sides, and the points where they meet are called vertices. A triangle has three angles, which are formed by the intersection of its sides.

To determine the possible length of the third side of a triangle, we need to apply the triangle inequality theorem which states that the sum of the lengths of any two sides is always greater than the third side.

Using this theorem, we can see that the possible lengths for the third side are:

2+8- x=-24 sole for x and show work

Answers

To solve for x in the equation 2 + 8 - x = -24, we can follow these steps:

1. Combine the constants on the left-hand side of the equation:

10 - x = -24

2. Subtract 10 from both sides of the equation:

- x = -34

3. Multiply both sides of the equation by -1 to isolate x:

x = 34

Therefore, the solution to the equation 2 + 8 - x = -24 is x = 34.

We can check the answer by plugging in x = 34 into the original equation:

2 + 8 - 34 = -24

-24 = -24

Since the left-hand side is equal to the right-hand side, the solution is correct.

Mark Chase and Beatrice are running at 100 m race which list represents the sample space of all the possible ways in which the three runners can win first second and third place is if there were four runners and three positions to be one where else would the sample size be

Answers

We have 24 possible permutations because there are four choices for the first place, three choices for the second place (as two people have already won first and second place), and two choices for the third place (as three people have already won first, second, and third place).

Where else would the sample size be?

For the 100 m race with Mark Chase and Beatrice, the sample space of all the possible ways in which the three runners can win first, second, and third place is:

{M-C-B, M-B-C, C-M-B, C-B-M, B-M-C, B-C-M}

where M stands for Mark, C stands for Chase, and B stands for Beatrice. We have six possible permutations because there are three choices for the first place, two choices for the second place (as one person has already won first place), and one choice left for the third place.

If there were four runners and three positions to be won, the sample space would be:

{A-B-C-D, A-B-D-C, A-C-B-D, A-C-D-B, A-D-B-C, A-D-C-B, B-A-C-D, B-A-D-C, B-C-A-D, B-C-D-A, B-D-A-C, B-D-C-A, C-A-B-D, C-A-D-B, C-B-A-D, C-B-D-A, C-D-A-B, C-D-B-A, D-A-B-C, D-A-C-B, D-B-A-C, D-B-C-A, D-C-A-B, D-C-B-A}

where A, B, C, and D represent the four runners. We have 24 possible permutations because there are four choices for the first place, three choices for the second place (as two people have already won first and second place), and two choices for the third place (as three people have already won first, second, and third place).

The Results:

a) Cost of the bouncy castle for 20 children = £149

b) Number of children who went to the party = 14.

How to find the cost of the bouncy castle for 20 children?

a) To find the cost of the bouncy castle for 20 children, we can substitute the number of children, which is 20, into the formula provided:

Cost = £3.65 * number of children + £76

Cost = £3.65 * 20 + £76

Now we can estimate the cost:

Cost = £73 + £76

Cost = £149

Thus, the cost of the bouncy castle for 20 children = £149.

b) To find the number of children who went to the party based on the given cost of £127.10, we can rearrange the formula to solve for the number of children:

Cost = £3.65 * number of children + £76

£127.10 = £3.65 * number of children + £76

Subtracting £76 from both sides of the equation:

£127.10 - £76 = £3.65 * number of children

£51.10 = £3.65 * number of children

Now we can divide both sides of the equation by £3.65 to isolate the variable:

£51.10 / £3.65 = number of children

14 = number of children

Therefore, the number of children who went to the party = 14.

You are applying fertilizer to the football field field is 360 feet long is 160 feet why do you use 8 pounds of fertilizer per thousand square feet the fertilizer comes and 50 pound bags how many bags of fertilizer what you need to co

Answers

To cover the full football pitch, you will want 10 bags of fertiliser, rounded up to the nearest whole number.

What is area?

The term "area" refers to the volume of space occupied by a two-dimensional (2D) form or surface.

It's represented by squares.

You must multiply the length by the breadth of the football pitch to determine its total area:

field size for football = length x width

field size for football = 360 feet x 160 feet

field size for football = 57,600 square feet

You must now calculate how many thousands of square feet the football pitch has in order to get the total amount of fertiliser required:

the size of a football pitch in square feet = the size of the football pitch overall / 1,000

the size of a football pitch in square feet = 57,600 / 1,000

the size of a football pitch in square feet = 57.6

You must spread 8 pounds of fertiliser per 1,000 square feet of the football pitch because it is 57.6 thousand square feet in size.

Total required fertiliser quantity = 8 pounds per 1,000 square feet x 57.6 thousand square feet

Total required fertiliser quantity = 460.8 pounds

Given that the fertiliser is sold in 50-pound bags, you will require:

number of fertiliser bags = Total amount of fertilizer needed / Weight of each bag

number of fertiliser bags = 460.8 pounds / 50 pounds/bag

3. What two assumptions must be met when you are using
the z test to test differences between two means? Can the
sample standard deviations s, and so be used in place of
the population standard deviations o, and o₂?

Answers

When using the z-test to test differences between two means, the following two assumptions must be met:1. The two populations from which the samples are drawn must be normally distributed or the sample sizes must be large (Central Limit Theorem).2. The variances of the two populations must be equal.If these assumptions are met, we can use the formula for the z-test to calculate the test statistic and corresponding p-value.In practice, the population standard deviations are usually not known, and so we use the sample standard deviations to estimate them. However, if the sample sizes are large enough (usually at least 30), the Central Limit Theorem ensures that the sampling distribution of the means will be approximately normal regardless of the underlying population distribution, and so the z-test can still be used even if the population standard deviations are unknown. In this case, we use the sample standard deviations as estimates for the population standard deviations in the formula for the z-test.

Use the given conditions to find the exact values of sin(2u), cos(2u), and tan(2u) using the double-angle formulas. sin(u) = 5/13, pi/2 < u < pi.

Answers

According to the information, the exact values of sin(2u), cos(2u) and tan(2u) are sin(2u) = -120/169, cos(2u) = -1, and tan(2u) = -120/119.

How to calculate the exact values of sin(2u), cos(2u) and tan(2u)?

We can use the double-angle formulas to find the values of sin(2u), cos(2u), and tan(2u) in terms of sin(u) and cos(u).

sin(2u) = 2 sin(u) cos(u)cos(2u) = cos²(u) - sin²(u)tan(2u) = (2 tan(u)) / (1 - tan²(u))

First, we need to find cos(u) using the Pythagorean identity:

cos²(u) + sin²(u) = 1cos²(u) = 1 - sin²(u)cos(u) = ±sqrt(1 - sin²(u))

Since pi/2 < u < pi, we know that sin(u) is positive and cos(u) is negative. Therefore:

cos(u) = -sqrt(1 - (5/13)²) = -12/13

Now we can substitute sin(u) and cos(u) into the double-angle formulas:

sin(2u) = 2 sin(u) cos(u) = 2 (5/13) (-12/13) = -120/169cos(2u) = cos²(u) - sin²(u) = (-12/13)² - (5/13)² = -144/169 - 25/169 = -169/169 = -1tan(2u) = (2 tan(u)) / (1 - tan²(u)) = (2 (5/12)) / (1 - (5/12)²) = (10/12) / (119/144) = -120/119

Therefore, sin(2u) = -120/169, cos(2u) = -1, and tan(2u) = -120/119.

During the first couple weeks of a new flu outbreak, the disease spreads according to the equation I(t) = 3900e^0.0514, where I(t) is the number of infected people t days after the outbreak was first identified. Find the rate at which the infected population is growing after 8 days and select the appropriate units.

Answers

The rate at which the infected population is growing after 8 days of the outbreak is approximately 1096.57 people per day, as determined by the derivative of the given function with respect to time.

To find the rate at which the infected population is growing after 8 days, we need to take the derivative of the given function I(t) with respect to t:

[tex]dI/dt = 3900(0.0514)e^(0.0514t)[/tex]

At t=8, the rate at which the infected population is growing is:

[tex]dI/dt = 3900(0.0514)e^(0.0514*8) = 1096.57[/tex]

Therefore, the rate at which the infected population is growing after 8 days is approximately 1096.57 people per day.

It is important to note that this rate of growth is an instantaneous rate at t=8, and it will likely change as time passes and the outbreak progresses. Furthermore, the rate of growth of the infected population depends on various factors such as the transmission rate of the virus, the effectiveness of preventive measures, and the availability of healthcare resources.

In conclusion, the rate at which the infected population is growing after 8 days of the outbreak is approximately 1096.57 people per day, as determined by the derivative of the given function with respect to time. This result provides insight into the early stages of a flu outbreak, but further analysis is required to understand the longer-term dynamics of the outbreak and the factors that affect the spread of the disease.
