Suppose the probability density function of a random variable X is

f(x)=[tex]\left \{ {{cx^{2}, 1\leq x\leq 2 } \atop {0, else}} \right.[/tex]

a. Find the value of constant c

b. Find the value of P(X>3/2)

The value of,

Given **function** f(x) = cx for 1 ≤ x ≤ 2

a) To find the value of constant x, we have to use the following p.d.f condition as shown below,

[tex]\int\limits^a_b {x} \, dx =1[/tex]

here, a is -∞ and b is ∞.

From the above condition to find the value of c,

[tex]\int\limits^2_1{cx^2} \, dx[/tex] = 1

c * [[tex]\frac{x^3}{3}[/tex]]²₁ = 1

c * [8/3 - 1/3] = 1

c * 7/3 = 1

c = 3/7.

b) To find the value of P(x>3/2) we have to** substitute** the value of 3/2 in the given expression of f(x) = 3/7 * x²

f(3/2) = 3/7 * (3/2)²

Water flows from the bottom of a storage tank. After t minutes, the water is flowing at a rate of r(t)=200-4t liters per

minute, where 0≤t<50. Find the amount of water (in liters) that flows from the tank between the 7 minute mark and the

37 minute mark.

The total **amount** of water that flows from the storage tank between the 7 minute mark and the 37 minute mark is 720 liters.

The amount of fluid that moves through a pipe or other container over a given amount of **time**.

The amount of water that flows from the storage tank between the 7 minute mark and the 37 minute mark can be calculated using the equation for the rate at which the water is flowing.

Given that the **rate** at which the water is flowing at time t is r(t)=200-4t liters per minute and that 0≤t<50, the total amount of water that flows from the storage tank between the 7 minute mark and the 37 minute mark can be calculated as follows:

Total amount of water = ∫r(t)dt

= ∫(200 - 4t)dt

= (200t - 4t²)

= (200(37) - 4(37²)) - (200(7) - 4(7²))

= 1924 - 1204

= 720 liters

The rate of flow decreases linearly with** **time, which means that the total amount of water flowing from the tank at any given time is equal to the area under the graph of the rate of flow.

This means that the total amount of water that flows from the tank between the 7 minute mark and the 37 minute mark can be calculated by integrating the rate of flow function over the given time interval.

the probability of rolling a 4 or an even number of the die is thrown 2 times. (6 sided dice)

**The probability of rolling a 4 on a single throw of a fair 6-sided die is 1/6, since there is only one way to roll a 4 and there are 6 equally likely outcomes in total.**

**The probability of rolling an even number on a single throw of a fair 6-sided die is 3/6, or 1/2, since there are three even numbers (2, 4, and 6) out of six possible outcomes.**

**To find the probability of rolling a 4 or an even number on a single throw, we can add the probabilities of these two events:**

**P(4 or even) = P(4) + P(even) - P(4 and even)**

**where P(4 and even) is the probability of rolling a 4 and an even number on the same throw. Since there is only one outcome (rolling a 4), which is not even, this probability is 0.**

**Therefore:**

**P(4 or even) = P(4) + P(even) - P(4 and even)**

** = 1/6 + 1/2 - 0**

** = 2/3**

**So the probability of rolling a 4 or an even number on a single throw of a 6-sided die is 2/3.**

**If the die is thrown 2 times, the probability of rolling a 4 or an even number on both throws is the product of the probabilities of rolling a 4 or an even number on each throw:**

**P(4 or even on both throws) = P(4 or even) × P(4 or even)**

** = (2/3) × (2/3)**

** = 4/9**

**Therefore, the probability of rolling a 4 or an even number on both throws of a 6-sided die is 4/9.**

Rounding to three decimal places, the **confidence interval** is (0.419, 0.574).

The sample proportion, p′ = 0.842, which is the point estimate of the population **proportion**, must be determined in order to calculate the confidence interval. Given that CL = 0.95 is the requested confidence level, = 1 - CL = 1 - 0.95 = 0.05 ( 2) ( 2) = 0.025.

**Confidence interval**=proportion±margin of error

CI = p ± ME

The proportion is:

p = x / n

p = 55/110

p = 0.5

Margin of error=critical value × standard error

ME = CV × SE

n > 30, so we can approximate CV with a **normal distribution**.

The **station** earned **$1485** in revenue from selling the gas.

In this problem, we are given two **vectors**, v and w, representing the number of gallons of gas sold at a station and the corresponding prices per gallon, respectively. We are asked to find the dot product of these two vectors, which is a **scalar** quantity known as the "Vw". We will then interpret the meaning of this dot product in practical terms.

To find the dot product of v and w, we will use the formula:

Vw = v . w = (210)(2.8) + (300)(2.99)

Vw = 588 + 897 = 1485

Therefore, the value of Vw is 1485.

Practical terms: The dot product of two vectors is a scalar quantity that represents the "projection" of one vector onto the other. In this case, the dot product Vw represents the **total revenue** earned by selling regular and premium gasoline at the given station.

The components of v **represent** the number of gallons of regular and premium gas sold, while the components of w represent the respective prices per gallon for each kind of gas. Multiplying the number of gallons sold by the price per gallon gives the total revenue earned for each type of gas. Adding these two values together gives the total revenue earned for both types of gas.

Therefore, the dot product Vw represents the total revenue earned by selling all the gas at the given station. In practical terms, this means that the **station** earned **$1485** in revenue from selling the gas.

A alone to do the work

So it would **take **A 10 **days **to do the whole job **alone**.

An **equation **is a statement that asserts the equality of two expressions. It typically contains variables, constants, and mathematical operations such as addition, subtraction, multiplication, **division**, exponentiation, etc. The goal of solving an equation is to find the values of the variables that make the equation true. Equations are used in a variety of mathematical contexts, including algebra, calculus, and geometry, as well as in physics, **engineering**, and many other fields.

Here,

Let's denote A's speed as "a" and B's speed as "b" (in units of work per day). Then, we know that:

In 5 days, A and B together completed the job, so we can write: 5(a + b) = 1 (where 1 represents the whole job).

If A worked at twice the speed (2a) and B worked at half the speed (0.5b), then they would complete the job in 4 days, so we can write: 4(2a + 0.5b) = 1.

We can simplify the second equation by multiplying out the brackets and collecting like terms:

8a + 2b = 1

Now we have two equations with two unknowns. We can solve for one of the variables in terms of the other, and substitute the result into the other equation to find the value of the remaining variable. Let's solve for "b" in terms of "a" from the first equation:

5(a + b) = 1

5b = 1 - 5a

b = (1/5) - a

Now we can substitute this expression for "b" into the second equation:

8a + 2b = 1

8a + 2((1/5) - a) = 1

8a + (2/5) - 2a = 1

6a = (3/5)

a = (1/10)

So A can do 1/10 of the job in one day. To find out how long it would take A to do the whole job alone, we can use the formula:

time = amount of work / rate

Since A can do the whole job alone, the amount of work is 1, and A's rate is 1/10. Therefore:

time = 1 / (1/10)

The base of a right prism ABC is an isosceles triangle with AB = BC and m∠ACB 35°. The diagonal of lateral face ABA is 18 cm and m∠BAB = 50°. Find the volume of the prism. Round your answer to the nearest cm

ChatGPT

Let AB = BC = x be the base of the isosceles triangle ABC. Then, the third side AC is:

AC = 2x * sin(35°)

Using the sine rule in triangle ABA, we have:

AB / sin(50°) = 18 / sin(80°)

Solving for AB, we get:

AB = 18 * sin(50°) / sin(80°)

The height of the prism is AB * cos(35°). Therefore, the volume of the prism is:

V = (1/2) * x^2 * 2x * sin(35°) * AB * cos(35°)

Substituting the values we have calculated, we get:

V = (1/2) * x^2 * 2x * sin(35°) * [18 * sin(50°) / sin(80°)] * cos(35°)

V ≈ 351 cm^3

Therefore, the volume of the prism is approximately 351 cubic centimeters.

The **probability** of rolling an even or divisible by 3 numbers is 2/3

When a single fair die is rolled, there are six possible **outcomes**:

1, 2, 3, 4, 5, or 6.

Of these outcomes, three are **even **(2, 4, and 6) and two are divisible by 3 (3 and 6). However, since the number 6 is both even and divisible by 3, we must count it only once to avoid overcounting. Thus, four outcomes are either even or divisible by 3: 2, 3, 4, and 6.

The probability of rolling an even or divisible by 3 number is the sum of the probabilities of these four outcomes, which is:

P(even or divisible by 3) = P(2) + P(3) + P(4) + P(6)

Set of tall students of class 10 is a set. Thus, option C is the correct answer.

A set is defined as objects or things that can be justified as similar things combined together and grouped together.

The other sets are not specified. When we look at option A it is said that all the men are tall so they have a common factor i.e. they are tall but could have been more specified. Also in option B it is said that all the women are beautiful, here the common factor is beautiful but it could have been more specified. Similarly option d, option e and option f are also not specified.

When we look at option c, here it specified that the tal students are of class 10 and so I consider option "c" is the correct answer.

find the area of the shaded region

The **area **of the **shaded **region is 51.75 in².

From the figure

**Radius **of semicircle = √25² - 20²

=√625- 400 = 15 inch

Now, Area of **Trapezium **= 1/02 ( a +b ) h

= 1/2 (17 + 37) x 15

= 1/2 (54) x 15

= 27 x 15

= 405 in²

Then, Area of **Shaded **region

= Area of Trapezium - Area of semicircle

= (405 - πr²)

= 405 - 353.25

= 51.75 in²

The earrings that Mrs.Moore wants to buy are $55.00. She won’t buy them until they are at least 45% off. What is the most that Mrs.Moore is willing to spend?

**Answer:**

$30.25

**Step-by-step explanation:**

55% of 55$ is $30.25. she wants 45 % off of 55$. which is $24.75. 55-24.75 is 30.25

$30.25

since it's 45% off, you need to subtract 45% from 100%

100%-45%=55%

then turn the % into a decimal

55%/100=0.55

now multiply the original price by 0.55

0.55*55=30.25
