The upper arm length of females over 20 years old in the United States is approximately Normal with a mean of 35.8 cm and a standard deviation of 2.1 cm. sing the 68-95-99.7 rule and the curve you labeled for the previous question: a. Between what values do the upper arm lengths of females over 20 95% of the time? (2 pts) b. What percent of women over 20 have upper arm lengths less than 33.7 cm?

i think the answer is b.

step-by-step explanation:

not 100% sure though.

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.

the answer is:

the lateral area is equal to

to find the lateral area of the square pyramid, first we need to find the perimeter of the base, and then, find the lateral area using the following formulas:

where,

s, is the base length

slant height, is the height of a the side of the pyramid

we are given:

now, calculating the perimeter of the base, we have:

then, calculating the lateral area:

hence, we have that the lateral area is equal to

have a nice day!
