Answer:

m = 3/2

b = -3

Equation:

y = 3/2x - 3

Step-by-step explanation:

m = rise/run

rise = 3

run = 2

b = y-intercept

y-intercept is -3

Equation: y = mx + b

y = 3/2x + (-3)

y = 3/2x - 3

The ratio of boys to girls is 4:3 .T here are 35 students in a class how many students are boys ?? Pleaseee help

evablogger [386]

There are 20 boys in the class. The ratio is 4:3 so that means 4 out of 7 are boys and 3 out of 7 are girls. Divide 35 by 7 and you get 5. 5 times 4 is 20. 5 times 3 is 15. add them together and you have 35 students in total. So 20 students are boys and 15 students are girls.

For this set of data,<br> 89, 88, 84, 87, 89, 84, 84, 83, 85, 89, 84<br> Find the standard deviation

Ilia_Sergeevich [38]

Answer: 2.2962419891482

Step-by-step explanation: First get the mean of the numbers or the average

the mean in this case is 86

then subtract each number by the mean of 86

the numbers then become : 3, 2, -2, 1, 3, -2, -2, -3, -1, 3, -2

then square all the numbers to get : 9, 4, 4, 1, 9, 4, -4, 9, 1, 9, 4

then find the mean of those numbers which is 5.2727272727273

then find the square root of this number to find the standard deviation

2.2962419891482 is the standard deviation
