Standard deviation = 3.2 + 4 = 7.2
Range = 20 + 4 = 24
If the values are multiplied by 5
Mean = 15(5) = 75
Median = 16(5) = 80

Aleah buys 2 DVDs for $6 and 4 CDs for $8. Her friend, Ling, wants to buy 4 DVDs and 2 CDs. How much will Ling have to pay?
Aleah's brother, Pierre, wants to spend $20 on DVDs and CDs. What combination of DVDs and CDs could he buy?
Answers
Answer:
Step-by-step explanation:
$6/(2 DVDs) = $3/DVD, and $8/(4 CDs) = $2/CD
a DVD costs $3
a CD costs $2
Ling bought 4 DVDs and 2 CDs for 4×$3 + 2×$2 = $16.
Pierre bought d DVDs and c CDs for $20.
d is 0, 2, 4, or 6
c = (20-3d)/2
(d,c) = (0,10), (2,7), (4,4), or (6,1)

Answer: f(3) is 5.
Step-by-step explanation:
The value of the function f(3) is 5 from the given graph.
What is a function?A relation is a function if it has only One y-value for each x-value.
We have to find the value of f(3) from the given graph.
Graph is a mathematical representation of a network and it describes the relationship between lines and points.
The value of f(3) is 5.
To find this we have to draw a perpendicular line at x=3.
Now let us check the corresponding point of y where the point and perpendicular line intersect.
Hence, the value of the function f(3) is 5 from the given graph.

Factorization of the given algebraic expression in its' simplest form is; B.–2(a + 6)
How to factorize an Algebraic Expression?To factorize an algebraic expression, it means that the highest common factors of the terms of the specific algebraic expression are determined and then we group the terms accordingly.
We are given the algebraic expression as;
6a – 4(2a + 3)
Multiplying the bracket out gives us;
6a - 4(2a) - 4(3)
= 6a - 8a - 12
= -2a - 12
Now, the highest common factor of the expression is 2 and so we have;
-2(a + 6)
