The standard deviation of the volumes of blood draws in purple-top tubes is known to be approximately 4 milliliters ( mls ). Later, in problem # 4 , we will wish to construct a 95% confidence interval for the mean volume of blood draws in purple top tubes. The volumes of 75 blood draws in purple-top tubes are determined. The sample mean volume is 6 ml. The sample standard deviation is 2.5 ml. Identify the following:.
a. x=
b. σ =
c. n =

answer: 1 2 3 6

step-by-step explanation:

1x6=6 2x3=6

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

where is the option given

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!
