Answer:
Step-by-step explanation:
Since the weight of the products are normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = weight of the product.
µ = mean weight
σ = standard deviation
From the information given,
µ = 4 ounces
Variance = 0.25²
σ = √variance = √0.25² = 0.25
We want to find the probability that a randomly selected unit from a recently manufactured batch weighs no more than 3.5 ounces. It is expressed as
P(x ≤ 3.5)
For x = 3.5,
z = (3.5 - 4)/0.25 = - 2
Looking at the normal distribution table, the probability corresponding to the z score is 0.0228

Answer: y = 3x-10</h3>
==============================================================
Explanation:
Select any two points from the diagonal line. I'll pick (0,-10) and (2,-4).
Use these points in the slope formula
m = (y2 - y1)/(x2 - x1)
m = (-4 - (-10))/(2 - 0)
m = (-4 + 10)/(2 - 0)
m = 6/2
m = 3
The slope is 3.
The y intercept is b = -10 since this is the location where the diagonal line crosses the vertical y axis.
The values m = 3 and b = -10 have us go from y = mx+b to y = 3x-10
