Arecent report in a women magazine stated that the average age for women to marry in the united states is now 25 years of age, and that the standard deviation is assumed to be 3.2 years. a sample of 50 u. s. women is randomly selected. find the probability that the sample mean age for 50 randomly selected women to marry is at most 24 years.

0.0136

Step-by-step explanation:

Given : Mean :

Standard deviation :

Sample size :

The formula to calculate the z-score :-

For x = 24

The p-value =

Hence, the probability that the sample mean age for 50 randomly selected women to marry is at most 24 years = 0.0136

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
