The number of miles did Tina ride when (1 mile ≈ 1.6 kilometers) so it should be considered as the 25 miles.
Calculation of the number of miles:Since
By the end of Tina’s bike ride, she traveled a distance of 40 kilometers.
And we know that
1 mile ≈ 1.6 kilometers
So,
[tex]= 40 \div 1.6[/tex]
= 25 miles
hence, The number of miles did Tina ride when (1 mile ≈ 1.6 kilometers) so it should be considered as the 25 miles.

Some teenagers collected trash for a beach clean-up. The data for the number of pounds of trash collected by each teenager are shown below.
26, 26, 21, 22, 20, 25, 35
What is the range of the data?
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.
What is the range of a data set?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.

Find the point P that is 2/5 of the way from A to B on the directed line segment AB if A (-8, -2) and B (6, 19).
The location of the point P that is 2/5 of the way from A to B on the directed line segment AB if A(x, y) = (- 8, -2) and B(x, y) = (6, 19) is P(x, y) = (- 12/5, 32/5).
How to determine the location of a point within a line segment
By geometry we know that a line segment is generated from two distinct points set on a plane. The location of the point P within the line segment can be found by means of the following vectorial formula:
P(x, y) = A(x, y) + k · [B(x, y) - A(x, y)], 0 < k < 1 (1)
Where:
A(x, y) - Initial pointB(x, y) - Final pointk - Distance factorIf we know that A(x, y) = (- 8, - 2), B(x, y) = (6, 19) and k = 2/5, then the location of the point P is:
P(x, y) = (- 8, -2) + (2/5) · [(6, 19) - (- 8, -2)]
P(x, y) = (- 8, -2) + (2/5) · (14, 21)
P(x, y) = (- 12/5, 32/5)
The location of the point P that is 2/5 of the way from A to B on the directed line segment AB if A(x, y) = (- 8, -2) and B(x, y) = (6, 19) is P(x, y) = (- 12/5, 32/5).

4. Gabby ate 25 % of a whole pepperoni pizza.
Lebron ate 1/8 of the pizza.
What fraction of the pizza was left for Mohamed to eat?
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.

Suppose you have some money to investfor simplicity, $1and you are planning to put a fraction w into a stock market mutual fund and the rest, , into a bond mutual fund. Suppose that $1 invested in a stock fund yields after 1 year and that $1 invested in a bond fund yields , suppose that is random with mean 0.07(%) and standard deviation , and suppose that is random with mean (%) and standard deviation . The correlation between and is . If you place a fraction w of your money in the stock fund and the rest, , in the bond fund, then the return on your investment is .
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.
