A standardized mathematics test given to 14,000 students had the scores normally distributed. The mean was 850 and the standard deviation was 75. A student scoring below 775 points was deficient in mathematics. About how many students were rated deficient? Please help ASAP I'm having a hard time with this problem!!! :(

4444444444444 i think

$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

actually your concept is wrong

step-by-step explanation:

150% of x =300

150x=300×100

x=(300×100)÷150

x=200
