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%
The matching is given below.
- Doubling ⇒ 2
- Quadrupling ⇒ 4
- Tripling ⇒ 3
- Halving ⇒ 1/2
<h3>What is an exponent?</h3>
Let a be the initial value and x be the power of the exponent function and b be the increasing factor. The exponent is given as
y = a(b)ˣ
You are asked to write exponential equations from word problems.
We know that factor 2 represents doubling, factor 4 represents quadrupling, factor 3 represents tripling, and factor 1/2 represents halving.
Then the matching is given below.
- Doubling ⇒ 2
- Quadrupling ⇒ 4
- Tripling ⇒ 3
- Halving ⇒ 1/2

Answer:
4
Step-by-step explanation: Its 4 becuase you plug in the zero like this'
f(x)=4-5(0)
f(0)=4-0
f(0)=4
So it will (0,4)
