With a height of 69 in, ronald was the shortest president of a particular club in the past century. the club presidents of the past century have a mean height of 71.6 in and a standard deviation of 2.4 in. a. what is the positive difference between ronald's height and the mean? b. how many standard deviations is that [the difference found in part (a)]? c. convert ronald's height to a z score. d. if we consider "usual" heights to be those that convert to z scores between minus2 and 2, is ronald's height usual or unusual?

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.

step-by-step explanation:

a child is 12 years old, and his father is 32 years older. in how many years will the age of the father be 2 times the age of the child?

******************

this needs to be the answer format, or else your answer is incomplete.

if the number of years is x, then the equation is

in __ years

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.

i have not got your picture clearly so see it once again
