leva [86]

Answer:

Step-by-step explanation:

Given that X the time to complete a standardized exam  in the BYU-Idaho Testing Center is approximately normal with a mean of 70 minutes and a standard deviation of 10 minutes.

We have 68 rule as 2/3 of total would lie within 1 std deviation, and 95 rule as nearly 95% lie within 2 std deviations from the mean.

We have std deviation = 10

Hence 2 std deviations from the mean

= Mean ±2 std deviations

=70±20

= (50,90)

Below 50, 0.25 or 2.5% would complete the exam.

Name:
Triss [41]

Answer:

A

Step-by-step explanation:

The reason it's A is because to make the ratio 1:1 you need to have a whole number you can't have half a pencil or pen, so what you need to do is add 22 and 96 and divide you should get 59, but if you add 23 to 96 and divide you get 59.5 and you can't have half a pencil (you can but that's not what were looking for). So in problems like this add and then divide by 2 and choose whole numbers because you can't have half in ratios cause that won't give the correct answer.

I need help on this word problem!
PSYCHO15rus [73]
Width be X,  length is X+15

area of garden = x(x+15)
area of sidewalk =  x(x+15) - (x-4)(x+11) = 632

X^2 + 15X - X^2 - 7X + 44 = 632
8X = 632-44 =588

X= 73.5  >> WIDTH  and LENGTH = 88.5
