A random sample of college students who owned cars revealed the following: out of 120 cars, 18 had manual transmissions. a)Construct a 95% confidence interval for the population proportion of college students who drive cars with manual transmissions. (Round your answers to 2 decimal places)b)Interpret the results (the interval) you got.(B) For a random sample of 25 over-weight men, the mean of the number of pounds that they were overweight was 30 pounds and the standard deviation was 4.2 pounds. a)Construct a 90% confidence interval for the population mean of the overweight pounds. (Round your answers to 2 decimal places)b)Interpret the results (the interval) you got.

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92

he is going to fill two shelves and the third shelf will only have five video games

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
