Question 15 of 20 (1 point) view problem in a pop-up assume that the mean systolie blood pressure of normal adults is 120 millimeters of mercury (mm hg) and the standard deviation is 5.6. assume the variable is normally distributed. use a graphing calculator and round the answers to four decimal places. part 1 if an individual is selected, find the probability that the individual's pressure will be between 120.4 and 121.9 mm hg. p120a

0.1052

Step-by-step explanation:

Given : Mean :

Standard deviation :

We assume the variable is normally distributed.

The formula for z-score is given by :-

For x=120.4

For x=121.9

The p-value =

The probability that the individual's pressure will be between 120.4 and 121.9 mm Hg = 0.1052

10 cm

step-by-step explanation:

if the polygon is a rectangle, then the perimeter is x+x+y+y. using the values that you gave, the perimeter is 3+3+2+2=10cm.

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
