Let x be a random variable representing the number of skateboards produced
a.) P(x ≤ 20,555) = P(z ≤ (20,555 - 20,500)/55) = P(z ≤ 1) = 0.84134 = 84.1%
b.) P(x ≥ 20,610) = P(z ≥ (20,610 - 20,500)/55) = P(z ≥ 2) = 1 - P(z < 2) = 1 - 0.97725 = 0.02275 = 2.3%
c.) P(x ≤ 20,445) = P(z ≤ (20,445 - 20,500)/55) = P(z ≤ -1) = 1 - P(z ≤ 1) = 1 - 0.84134 = 0.15866 = 15.9%
In order to solve this, we need to figure out how much ONE student spends.
dollars per student.
If 10 student spent for lunch, we just have to multiply our number by how much each student spends.
The most you can make is 16 because you need a dvd in each prize even though there is still pretzels and popcorn
Answer:
x>−7
Explanation:
Let's solve your inequality step-by-step.
−4x<28
Step 1: Divide both sides by -4.
−4x/−4 < 28/−4
x>−7
Answer: x>−7
Step-by-step explanation:
|x+5|=x+5
x+5=x+5
2x=0
x=undefined
