The weight of adults in some population follows a bimodal distribution with u = 160 pounds and o = 20 pounds. Random samples of size n=50 are selected from this population. The shape of the sampling distribution of x-bar will be A. bimodal
B. normal
C. skewed right

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.

step-by-step explanation:

:

the number 100 represents the number of trials in the experiment.

49/100 represents the experimental probability of the coin landing heads up.
