Firstly we need to count how much did the employees earn after the raises:

4% from $41,000 =
= 4/100 * 41,000 =
= 4 * 410 =
= 1644

4,5% from 43,700 =
= 45/1000 * 43,700 =
= 45 * 43,7 =
= 1966,5

3% from 39,700 =
= 3/100 * 39,700 =
= 3 * 397 =
= 1191

Now we need to sum up all the raises:

1644 + 1966,5 + 1191 = 4801,5

So now we can clearly see that answer A ($4,802) is the closest one to the total of all three raises.

A statistics professor plans classes so carefully that the lengths of her classes are uniformly distributed between 45.0 and 55.

LUCKY_DIMON [66]

Answer: 0.025

Step-by-step explanation:

The probability density function for a random variable that is uniformly distributed on interval [a,b] is given by :-

$f(x)=\dfrac{1}{b-a}$

Given : A statistics professor plans classes so carefully that the lengths of her classes are uniformly distributed between 45.0 and 55.0 minutes.

Let x be the random variable that denotes the lengths of her classes.

Then, the probability density function = $f(x)=\dfrac{1}{55-45}=\dfrac{1}{10}$

Now, the probability that a given class period runs between 50.25 and 50.5 minutes will be :-

$P(50.25$

Hence, the required probability =0.025

Assume that adults have IQ scores that are normally distributed with a mean of mu equals μ=105 and a standard deviation sigma eq

Over [174]

The probability that a randomly selected adult has an IQ less than

135 is 0.97725

Step-by-step explanation:

Assume that adults have IQ scores that are normally distributed with a mean of mu equals μ = 105 and a standard deviation sigma equals σ = 15

We need to find the probability that a randomly selected adult has an IQ less than 135

For the probability that X < b;

Convert b into a z-score using z = (X - μ)/σ, where μ is the mean and σ is the standard deviation
Use the normal distribution table of z to find the area to the left of the z-value ⇒ P(X < b)

∵ z = (X - μ)/σ

∵ μ = 105 , σ = 15 and X = 135

∴ $z=\frac{135-105}{15}=2$

- Use z-table to find the area corresponding to z-score of 2

∵ The area to the left of z-score of 2 = 0.97725

∴ P(X < 136) = 0.97725

The probability that a randomly selected adult has an IQ less than

135 is 0.97725

Consider the function represented by 9x+3y = 12 with x as the independent variable. How can this function be

Delicious77 [7]

Answer:

f(x) = -3x + 4

Step-by-step explanation:

Given function:

9x + 3y = 12

Putting this into slope-intercept form: y = mx + b

9x + 3y = 12
3y = -9x + 12
y = -3x + 4

Replacing y with f(x)

f(x) = -3x + 4

How to find the vertex of a function

belka [17]

Step-by-step explanation:

1.Get the equation in the form y = ax2 + bx + c.

2.Calculate -b / 2a. This is the x-coordinate of the vertex.

3.To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y. This is the y-coordinate of the vertex.
