Answer:

D. 15 pounds

Step-by-step explanation:

35-20=15

The range of the data that represents the number of pounds of trash collected by each teenager is 15.

The range is the difference between the Maximum value of the data set and the Minimum value of the dataset. Therefore, we can write the range as,

Range = Maximum value of the data set - Minimum value of the dataset

Given the data for the number of pounds of trash collected by each teenager as 26, 26, 21, 22, 20, 25, and 35.

Now, from the data, the Maximum value of the data set is 35 and the Minimum value of the dataset is 20. Therefore, we can write the range of the data set as,

Range = Maximum value of the data set - Minimum value of the dataset

          = 35 - 20

          = 15

Hence, the range of the data that represents the number of pounds of trash collected by each teenager is 15.

The answer to your question is -1/4

Answer:

(-∞,∞)

any value makes the equation true

(its infinite)

Step-by-step explanation:

3(x + 2) = 7x + 6 - 4x

distribute

3x + 6 = 7x + 6 - 4x

combine like terms

3x + 6 = 3x + 6

move the variable to the other side

0 + 6 = 6

move the 6

0 = 0

Answer and Step-by-step explanation:

Solution:

Given:

Mean = 0.08

Standard deviation = 0.07

W = 0.75

The return on investment is:

R = W * RS + (1 – W)*RB

Compute the mean and standard deviation:

Mean:

E(R) = E[ W X RS + (1 – W) X RB]

The mean of R is given:

 µ = W * RS + (1 – W)*RB

      = 0.75 X 0.08 + (1 – 0.75) 0.05

      = 0.06 + 0.0125

     = 0.0725

Variance:

Var (R) = var [ w x RS + (1 – W)RB]

Var (R) = W 2 Var (RS )+ (1 –W)2 Var  (RB) + 2w (1-w)cov(RS , RB)

The standard deviation of R is given by:

∂2 = W2 X (0.07)2 + (1 – W) 2 X( 0.04)2 + 2 W (1 – W) X [0.07 X 0.04 X 0.25]

  Where [0.07 X 0.04 X 0.25] is correlation between RS and RB.

Answer:

8/27. Though the question is a bit confusing. If your asking which term describes it, its this a multiple choice question?

Step-by-step explanation:

8 /27

is already in the simplest form. It can be written as 0.296296 in decimal form (rounded to 6 decimal places).

Steps to simplifying fractions :

Find the GCD (or HCF) of numerator and denominator

GCD of 8 and 27 is 1

Divide both the numerator and denominator by the GCD

8 ÷ 1

27 ÷ 1

Reduced fraction:  

8 /27

Therefore, 8/27 simplified to lowest terms is 8/27.

Answer:

-8/27

Answer:

There is 5/8 left for Mohamed to eat.

Step-by-step explanation:

Let's put everything into fractions of 1/8. knowing that 25% is 1/4 or 2/8, 1/8 + 2/8= 3/8. and to find the answer, you need to subtract 3/8 from 8/8 or 1.

As a result, 5/8.

1/8 = 12.5%

12.5% + 25% = 37.5%

We need to know how much is left.

37.5% is gone, so 100% - 37.5% = 62.5%

62.5% is left for Mohamed to eat.

62.5% = 5/8.

5/8 of a pizza is left for mohamed to eat.

Answer:

2 hours or 120 minutes

Step-by-step explanation:

So, let's assume that she studies the same amount each day. If she has studied math for a total of 60 minutes, she should have studied for 4 days because 60 (total) divided by 15(time each day) would equal to 4 (period of time). So we have to multiply 30 minutes by 4 (period) to get 120 minutes, which is 2 hours.

The equation of the line in the slope-intercept form will be 2x+y+1=0.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that,

The coordinate of the points are (x,y) = (-7, 13)

Slope, m = -2

The standard equation of a line is,

y = mx+c

Substitute the given coordinate value in order to find the intercept value as

13=-2×-7+c

13-14=c

-1=c

Put the values in the standard equation,

y = mx+c

y=-2x-1

Thus, the equation of the line in the slope-intercept form will be 2x+y+1=0.
