Question

Mrs. Varner deposited q dollars in a bank account that has been earning annual interest. The total value of the account is based on the function f(x) = q • 1.025x, where x represents the number of years the money has been in the account. If no deposits or withdrawals are made after the initial deposit, which equation represents the total value of the account 5 years from now?

Solution 1

The correct answer is b

Solution 2

The answer is f(x) = q • 1.025x + 5

Question

What is the center of the circle represented by this equation?
x2 + (y + 9)2 = 25

Solution 1

Hello!

The equation for a circle is

(h, k) is the center

You find what numbers make the equation

Since x is not subtracted from anything h = 0

Since k is positive k is the negative of that number

The equation is

The center is (0, -9)

Hope this helps!

Question

Scientists discovered a large star 400,000 light years from Earth.A light-year is about 5,880,000,000,000 miles.What is the distance of the large star from Earth in scientific notation?

Solution 1

So if you want to find the distance, you would take 400,000x5,880,000,000,000=

2.35200000E+18. So your answer would be 2.35200000E+18 in scientific notation it would be 2.35200000x10^18. I hope this helps!

2.35200000E+18. So your answer would be 2.35200000E+18 in scientific notation it would be 2.35200000x10^18. I hope this helps!

Question

The heights of the trees for sale at two nurseries are shown below. Heights of trees at Yard Works in feet : 7, 9, 7, 12, 5 Heights of trees at The Grow Station in feet : 9, 11, 6, 12, 7 Which statements are true regarding the measures of center and variability of these data sets? Check all that apply. The mean of tree heights at Yard Works is 7 feet. The mean of tree heights at Yard Works is 8 feet. The mean of tree heights at The Grow Station is 9 feet. The mean of tree heights at The Grow Station is 10 feet. The mean absolute deviations of the tree heights at both yards is 2. The mean absolute deviations of the tree heights at both yards is 3. Mark this and return Save and Exit

Solution 1

**Answer:**

The mean of tree heights at **Yard Works is 8 feet** and at **Grow Station is 9 feet**.The **mean absolute deviation of the tree heights at both yards is 2.**

**Step-by-step explanation:**

1). Height of the trees at Yard Works are = 7,9,7,12,5 feet

So mean height of the trees = (7+9+7+12+5)÷5

= 40÷5 =8 feet

Standard deviation of the trees at Yard works = ∑(║(height of the tree-mean height of the tree))║/(number of trees)

(height of the tree-mean height of the tree)= ║(7-8)║+║(9-8)║+║(7-8)║+║(12-8)║+║(5-8)║ = (1)+1+(1)+4+(3)= 10

Therefore standard deviation = (10)/(5) =2

2). In the same way mean height of the trees at Grow Station=(9+11+6+12+7)/5= 45/5 = 9

Now we will calculate the mean deviation of the tress at Grow Station

= ∑║(height of the tree-mean height of the tree)║/(number of trees)

= ║(9-9)║+║(11-9)║+║(6-9)║+║(12-9)║+║(7-9)║/(5)

= (0+2+3+3+2)/5

= 10/5 =2

Therefore The mean of tree heights at Yard Works is 8 feet and at Grow Station is 9 feet.The mean absolute deviation of the tree heights at both yards is 2.

Question

Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar. The area of a circle is 78.5 square centimeters, and a subtending arc on the circle has an arc length of 6. The estimated value of is 3.14. The measure of the angle subtended by the arc is

Solution 1

To solve this problem you must apply the proccedure shown below:

1. You have that the arc lengt is 6 and the area os 78,5 cm^2. Therefore, you must apply the following formula:

Arc lenght=radius x θ

2. The value of the radius is:

A=2πr²

r=√A/2π

r=√25

r=5

3. When you clear θ , you obtain:

θ=Arc length/radius

θ=6/5 radians

Therefore,

Question

For either linear regression or multiple regression, the standard error of estimate can be computed as ____. a. the square root of msresidual
b. the square root of msregression
c. msresidual/(n – 2)
d. msregression/(n – 2)

Solution 1

The standard error of the estimate is a measure of the accuracy of predictions.

It is given by the square root of the mean square residual.

Therefore, for either linear regression or multiple regression, the standard error of estimate can be computed as the square root of msresidual.

It is given by the square root of the mean square residual.

Therefore, for either linear regression or multiple regression, the standard error of estimate can be computed as the square root of msresidual.
