The average number of skateboards produced per day last year is 310.
<h3>What is a normal distribution?</h3>
It's the probability curve of a continuous distribution that's most likely symmetric around the mean. On the Z curve, at Z=0, the chance is 50-50. A bell-shaped curve is another name for it.
We have:
The standard deviation of skateboards produced was 20 skateboards. They found they produced up to 280 skateboards on 93.32% of the days last year.
Z- score at 93.32% is -1.5
We know:


μ = 280 + 30
μ = 310
Thus, the average number of skateboards produced per day last year is 310.

Answer: A
<u>Step-by-step explanation:</u>
f(x) = 4x² - 5x + 3
<u> - g(x)</u> = <u> 2x - 7 </u>
f(x)-g(x) = 4x² - 3x - 4
The answer is (6 x 14) + 5 x12)
