and into 18 twice
so the ratio in its simplest form it 10:2

Answer 2

Answer: To find the ratio between 2 numbers, you need to find the GCF of those 2 numbers. If the GCF is the ratio, the ratio is in it's simplest form.
GCF of 90 and 18 is 18
divide both numbers by the GCF and the final simplest ratio is 5:1

Will 3/5 x 2/7 be less than, greater than or equal to 3/5

Answers

3/5 times 2/7=6/35
compare 3/5 to 6/35

5 times 7=35

3/5 times 7/7=21/35

21/35 ? 6/35
21 ? 6
21> 6

an easy way is if we do

3/5=x, a random number
rememberig that taking a fraction of something makes it smaller

x times fraction is smaller than x
so
3/5 times 2/7 is less than 3/5

3/5×2/7=6/35
3/5=3/5×7/7=15/35
3/5 ×2/7 is less than 3/5

Adult male heights are normally distributed with a mean of 70 inches and a standard deviation of 3 inches. The average basketball player is 79 inches tall. Approximately what percent of the adult male population is taller than the average basketball player?0.13%
0.87%
49.87%
99.87%

Answers

Given:
average height of a basketball player = 79 inches
μ = 70 inches
σ = 3 inches

standardize x to z = (x - μ) / σ
P(x > 79) = P( z > (79-70) / 3)
= P(z > 3) = 0.0013
0.0013 x 100% = 0.13%

0.13 % of the adult male population is taller than the average basketball player.
