According to a study, 68% of all males between the ages of 18 and 24 live at home. (Unmarried college students living in a dorm are counted as living at home.) Suppose that a survey is administered and 143 of 206 respondents indicated that they live at home. (a) Use the normal approximation to the binomial to approximate the probability that at least 143 respondents live at home. (b) Do the results from part (a) contradict the study?
(a) P(X≥143)=

2.56 is the width of the garden

step-by-step explanation:

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or

nothing extraneous has been found!

step-by-step explanation:

its 512 because parenthesis and to the 2nd power is 512 so it will be 512
