A survey of 500 non- fatal accidents showed that 134 involved the use of a cell phone. Find a point estimate for p, the population proportion of non- fatal accidents that involved the use of a cell phone.

0.268

Step-by-step explanation:

The point estimate for a population proportion obtained through a sample is simply given by the number of occurrences in the sample (134 uses of phone), divided by the sample size (500 non-fatal accidents). The proportion 'p' is:

The population proportion of non- fatal accidents that involved the use of a cell phone is 0.268.

x+y = 29, 5x + 2y = 100

step-by-step explanation:

i'm guessing it was a multiple first option was the correct answer

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
