How many times greater is the digit in the tenths place than in the hundredths place?

1 answer:

4 0

That depends on what the digits are. It could be anywhere between zero times and infinite times. If both are the same digit and not zero, then the tenth is ten times the size of the hundredth.

Answer:

A has the largest surface area.

Step-by-step explanation:

Surface Area of A = 2(10*3.5) + 2(10*4) + 2(4*3.5)

= 70 + 80 + 28

= 178 in^2.

For B:

Area = 2(12*3.2) + 2(12*2.8) + 2(2.8*3.2)

= 76.8 + 67.2 + 17.92

= 161.92 in^2.

Jeremy's score was 1.75 standard deviations above the mean. which kf thr following is closest to his percentile rank

Gelneren [198K]

The answer is 96%.

Explanation:
It is generally presumed that the scores are normally distributed.

1) You are given how many standard deviations from the mean Jeremy's score is. This is exactly the definition of the z-score. Therefore z = 1.75

2) Look at a left-tail z-table in order to find the area of the normal curve on the left of your z-score (see picture attached). A = 0.9599

3) Multiply the area by 100 in order to find the percentile:
<span>0.9599 </span>× 100 = 95.99
Therefore, 95.99% of the students scored less than Jeremy.

Hence, the answer is 96%.
