Answer:

  AD = 9 cm

Step-by-step explanation:

Recognize all of the triangles are 30°-60°-90° triangles that have side ratios of 1 : √3 : 2. That is, the longest side is double the length of the shortest side.

  CB = 2(DB)

  DB = CB/2 = (6 cm)/2 = 3 cm

  AB = 2(CB)

  AB = 2(6 cm) = 12 cm

  AD +DB = AB

  AD +3 cm = 12 cm

  AD = 9 cm . . . . . . . . . . subtract 3 cm

1. Mrs. Shelley's class is reading The Lion, the Witch,

how many pages can they read in 5 weeks?

Answers

Answer:

80 weeks

Step-by-step explanation:

We can use proportions to figure out the answer to this problem:

[tex]\frac{16}{1} = \frac{x}{5}[/tex]

16 pages every week, and some amount of pages every 5 weeks. Notice that if we can multiply 1 by 5 to get 5, we should be able to multiply 16 by 5 to get the value of x. 16 times 5 is 80, and this is the answer to our problem.

What is Graph?

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

Given,

ABCD is a rectangle.

ABCD is translated according to the rule (x, y) → (x + 6, y) to rectangle A′ B′ C′ D′ and then rotated 90° counterclockwise about the origin.

Translating means equivalent to shifting the base graph left or right in the direction of the x-axis. A graph is translated k units horizontally by moving each point on the graph k units horizontally.

The coordinates of rectangle after translations are A″ (–5, 1), B″ (1, –1), C″ (–1, 4), D″ (–5, 4)

Hence the coordinates of rectangle A″B″C″D″, A″ (–5, 1), B″ (1, –1), C″ (–1, 4), D″ (–5, 4)

If you selected two of these stocks at random, what is the probability that both the stocks in your selection had yields of 3.25% or more

Answers

Using the binomial distribution, it is found that there is a 0.04 = 4% probability that both the stocks in your selection had yields of 3.25% or more.

For each stock, there are only two possible outcomes, either it yields 3.25% of more, or it does not. The probability of an stock yielding 3.25% or more is independent of any other stock, which means that the binomial distribution is used to solve this question.

Binomial probability distribution

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters are:

x is the number of successes. n is the number of trials. p is the probability of a success on a single trial.

In this problem:

There are 2 stocks, hence [tex]n = 2[/tex]We suppose that 20% of them yield 3.25% of more, hence [tex]p = 0.2[/tex].

The probability of both is P(X = 2), hence:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 2) = C_{2,2}.(0.2)^{2}.(0.8)^{0} = 0.04[/tex]

0.04 = 4% probability that both the stocks in your selection had yields of 3.25% or more.

4x+12y=-16 solve for y show work

Answers

Solution for 4x-12y=16 equation:

Simplifying

4x + -12y = 16

Solving

4x + -12y = 16

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '12y' to each side of the equation.

4x + -12y + 12y = 16 + 12y

Combine like terms: -12y + 12y = 0

4x + 0 = 16 + 12y

4x = 16 + 12y

Divide each side by '4'.

x = 4 + 3y

Simplifying

x = 4 + 3y

What is the slope of the blue line

Hello there!

To find the slope of a line, we need to know at least two points contained in the graph of the line.

The slope [tex]m[/tex] of a line passing through the points [tex](x_0,~y_0)[/tex] and [tex](x_1,~y_1)[/tex] is given by the formula: [tex]m=\dfrac{y_1-y_0}{x_1-x_0}[/tex].

As we can see on the graph, two points contained on the line are [tex](0,~3)[/tex] and [tex](2,~0)[/tex].

Using the formula above, we get that:

[tex]m=\dfrac{3-0}{0-2}[/tex]

A rectangular area is to be enclosed and divided into thirds. The family has $880 to spend for the fencing material. The outside fence costs $10 per foot installed, and the dividers cost $20 per foot installed. What are the dimensions that will maximize the area enclosed

Answers

Answer:

\W = Width

L = Length

Draw rectangle W x L

Divde rectangle into thirds with two lines parallel with width.

Outside fance perimeter = 2 W + 2 L

Inside fance length = 2 W

Total cost :

( 2 W + 2 L ) * 10 $ + 2 W * 20 $ = 400 $

( 2 W + 2 L ) * 10 + 2 W * 20 = 400

20 W + 20 L + 40 W = 400

60 W + 20 L = 400 Divide both sides by 20

60 W / 20 + 20 L / 20 = 400 / 20

3 W + L = 20 Subtract 3 W to both sides

3 W + L - 3 W = 20 - 3 W

L = 20 - 3W

Area :

A = W * L =

W * ( 20 - 3W ) =

20 W - 3 W ^ 2

First derivation :

dA / dW = 20 - 3 * 2 * W = 20 - 6 W

If first derivation = 0 a function has a local maximum or a local minimum.

dA / dW = 0

20 - 6 W = 0 Add 6 W to both sides

20 - 6 W + 6 W = 0 + 6 W

20 = 6 W Divide both sides by 6

20 / 6 = 6 W / 6

20 / 6 = W

2 * 10 / ( 2 * 3 ) = W

10 / 3 = W

W = 10 / 3 ft

If second derivative < 0 then function has a maximum.

If second derivative > 0 then function has a mimum.

In this case second derivative = - 6

Second derivative < 0 so function has a maximum.

For W = 10 / 3 ft

L = 20 - 3W = 20 - 3 * 10 / 3 = 20 - 10 = 10 ft

Amax = W * L = 10 / 3 * 10 = 100 / 3 ft ^2

The amount of time taken to finish a Biology exam has a normal distribution with a mean of 80 minutes and standard deviation of 15 minutes. About what percent of test takers finished the exam less than 65 minutes

Answers

Answer:

15.86552112%

Step-by-step explanation:

Approximately 15.87% of test takers completed the exam in under 65 minutes.

How to find the percentage of test takers?

To find the percentage of test takers who finished the exam in less than 65 minutes, we need to use the normal distribution to find the proportion of test takers who fall within this time range.

First, we need to convert the time in minutes to a standard score, also known as a z-score.

The formula for calculating the z-score is:

z = (x - μ) / σ

where x is the value (in this case, the time taken to finish the exam), μ is the mean, and σ is the standard deviation.

Substituting the given values into the formula, we get:

z = (65 - 80) / 15 = -1

This means that the time of 65 minutes is 1 standard deviation below the mean.

Next, we can use a z-table or a calculator that can calculate the area under the normal curve to find the proportion of test takers who scored less than 65 minutes. This proportion is the same as the percentage of test takers who finished in less than 65 minutes.

Using a z-table or a calculator, we find that the proportion of test takers who scored less than 1 standard deviation below the mean is about 0.1587 × 100% = 15.87%. This is also the percentage of test takers who finished the exam in less than 65 minutes.

Therefore, about 15.87% of test takers finished the exam in less than 65 minutes.
