Answer:
15x+100(3) ≥ $1500
x ≥ 80 pages
Step-by-step explanation:
Let x represent the number of pages.
Manuel receives $15 per page = 15x
Plus $100 per month. Manuel would like to work for 3 months = 15x+100(3)
He wants to make at least $1500 during the summer
Thus the inequality we get is:
15x+100(3) ≥ $1500
Now solve the equation to find minimum number of pages:
15x+300 ≥ $1500
Combine the like terms:
15x ≥ 1500-300
15x ≥ $1200
Divide both sides by 15
15x ≥ $1200/15
x ≥ 80 pages
So first you combine all the equations and make them add up to 56.
The equation should look as such: 2y + 8 = 56
Then we solve for y
Work: 2y + 8 = 56
2y = 48
y = 24
I hope this helps!

Answer:
A. x^2 + 3x + 2
D. 3x^4 + 4x^3 - 3x^2 - 1
E. 3t^3 + 3t^2 + 2t
Step-by-step explanation:
Standard form is where the equation is set up so that the exponents decrease from left to right, and where you put a number with no variable or exponent last.
Answer:
865
Step-by-step explanation:
We have that in 95% confidence level the value of z has a value of 1.96. This can be confirmed in the attached image of the normal distribution.
Now we have the following formula:
n = [z / E] ^ 2 * (p * q)
where n is the sample size, which is what we want to calculate, "E" is the error that is 2% or 0.02. "p" is the probability they give us, 5 out of 50, is the same as 1 out of 10, that is 0.1. "q" is the complement of p, that is, 1 - 0.1 = 0.9, that is, the value of q is 0.9.
Replacing these values we are left with:
n = [1.96 / 0.02] ^ 2 * [(0.1) * (0.9)]
n = 864.36
865 by rounding to the largest number.
