Florida Highway Patrol reported that 28% of fatal accidents were caused by texting while driving. A random sample of 50 fatal accidents were studied. Let p^ represent the proportion of fatal accidents in the sample caused by texting while driving. What is the mean of the sampling distribution?
What is the standard deviation of the sampling distribution of accidents caused by texting?
Find the probability that more than 35% of the accidents in the sample were caused by texting.

i used to know but i learned it a long time ago sorry

step-by-step explanation:

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

step-by-step explanation:

yx = 36

step-by-step explanation:

cos f = opposite side/ hypotenuse

cos f = yw / yx

we know cos f = 4/9 and yw =16

4/9 = 16/yx

multiply each side by yx

4/9 yx = 16/ yx * yx

4/9 yx = 16

multiply each side by 9/4

9/4 * 4/9 yx = 16 *9/4

yx = 36
