the length of pregnancy terms for a particular species of animals are nearly normally distributed about a mean pregnancy length with standard deviation of 18 days. About what percentage of births would be expected to occur within 54 days of the mean pregnancy length?

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

$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

it would rotate about 180 degrees.
