Answer:
-Bell-shaped, A bell shaped picture, shown below, usually presents a normal distribution
Step-by-step explanation:
-Hope this helps butter cup :)
-8x + 4y = 20
-8x + 8x + 4y = 8x + 20
4y = 8x + 20
4 4
y = 2x + 5
Answer:
D. Make the column wider
Step-by-step explanation:
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.
