The distribution of life spans for gas ovens (G) has a mean of 15.0 years and a standard deviation of 4.2 years. The distribution of life spans for electric ovens (E) a mean of 13.4 years and a standard deviation of 3.7 years. Both distributions are moderately skewed to the right. Suppose we select a simple random sample of 35 gas ovens and a second simple random sample of 40 electric ovens. What is the probability that the sample mean lifespan for the electric ovens is greater than the sample mean lifespan of the gas ovens?

answer: a.   one is a factor of every whole number since every number is divisible by itself.

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61

answer: answer is b.
