Answer:
-4
Step-by-step explanation:
If you use the equation y = mx+b then you already know what the b term is because you have the y intercept. For the m (slope) you take the slope of the other line and use that because since there parallel they are going to run at the same angle (slope). Hope this helped. If you have any questions just ask.
Answer:a. 0.13% b. 2.28%
Step-by-step explanation:
Let x denotes the useful life of batteries.
Given: months,
Since X is normally distributed.
The probability that batteries with a useful life of less than 38 months
The percent of batteries with a useful life of less than 38 months =0.13%
The probability that batteries will last longer than 68 months
The percent of batteries that will last longer than 68 months =2.28%
Answer:
about 4650 square inches
Step-by-step explanation:
The area is the product of length and width. Each conversion factor cancels a unit we don't want and replaces it with a unit we do want.
(1.5 m)(2 m)((1 in)/(0.0254 m))^2 = 3/.00064516 in^2 = 4650.0093... in^2
≈ 4650 in^2
The photograph has an area of 4650 square inches.
