Answer:
First number - 30
Second number - 105
Step-by-step explanation:
2/5 of 75 would be 30, so it is the answer.
7/5 of 75 would be 105, so it is the answer.
This is how you would solve this problem.
Answer:
The sum of 2 numbers is 52. Express the product of the numbers, P, as a function of one of the numbers, x.
the answer is p(x) = -x² + 52x
Step-by-step explanation:
let the two numbers be x and y
the sum of the two numbers = x + y
≡ x + y = 52
make y the subject of equation
y= 52 - x
to express the product of the numbers, P, as a function of one of the numbers, x. implies that
P(x) = x(-x + 52)
finally,
p(x) = -x² + 52x
Answer:
The z value is - 2.88
Step-by-step explanation:
The formula of the z-score of a population is z = (x¯ - μ)/(σ/
)
The given in the problem is:
- μ = 121
- σ = 21
- x¯ = 112.35
- n = 49
Let us substitute all of these values in the rule above
Simplify up and down
z = - 2.883333
Round it to 2 decimal places
∴ z = - 2.88
The z value is - 2.88
