247,039 rounded to the nearest thousand is 247,000
Paint is bought to cover square footage. By looking at length and width, we can get the square footage that will total 150 square feet.
This area can be anything from a square to a long skinny rectangle. The thinner the rectangle, the longer the length.
Example: 10' x 15' = 150 sq.ft.
The longest WHOLE foot would be 150 feet long. This would create a rectangle 150' by 1' = 150 square feet.
I did notice you said surface area, which often is for prisms.
Answer:
95%
Step-by-step explanation:
About 95% of the area is within two standard deviation in standard normal distribution. This can be explained by finding the probability within 2 standard deviation using standard normal distribution.
P(z1<Z<z2)=P(-2<Z<2)
P(-2<Z<2)=P(-2<Z<0)+P(0<Z<2)
P(-2<Z<2)=0.4772+0.4772
P(-2<Z<2)=0.9544
Thus, About 95% of the area is between z2 and z2
