Answer:

G=93\ to\ 147

Step-by-step explanation:

From the question we are told that

Mean x= 120  

Standard deviation \sigma= 9

Percentage for men =99.75%

Generally the empirical rule 68%,95% and 99.7% of data value lay b/w 1,2,3 standard deviation of mean  

Standard deviation n= 9

Mean x= 120

Generally the interval  of systolic blood pressure for middle 99.7 of male G is mathematically given as

G=Mean \pm 3* \sigma

G=120 \pm 3*9

G=93\ to\ 147

A cashier earns $7 an hour. If x is the number of hours worked, which function represents the cashier’s earnings? y = 7x y = x 7
Vilka [71]
I think its 7x since x represents the hours she worked. So lets say that she worked for 5 hours this day. It would be 5*7 which is $35. So it is 7x and if there is any choices you might say it as well so we can help you better
