You work for a store that sells bicycles, tricycle, and tandem bikes. Bicycles have 2 wheels and 2 pedals. Tricycles have 3 wheels and 2 pedals. Tandem bicycles have 4 pedals and 2 wheels. If the store contains 144 bikes of all kinds,378 pedals and 320 wheels, how many bicycle, tricycle, and tandem bikes are in the shop.

honestly bro aint no one got time to answer these dumb question just do it p***y

step-by-step explanation:

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

what i would say the best answer is a. 40.5

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
