Answer:
20/30
Step-by-step explanation:
Five girls plus five boys equals ten, thirty minus ten equals twenty.
To find the mean add all the numbers and dived by the number of numbers. So 15 + 23 + 14 + 17 + 21 = 90 / 5 = 18. The mean is 18.
Answer:
Step-by-step explanation:
Slope
<em>Givens</em>
y2 = 3
y1 = 2
x2 =0
x1 = 4
<em>Equation</em>
m = (y2 - y1)/(x2 - x1)
m = (3-2)/(0 - 4)
m = 1 / - 4
y intercept
Use any point to get the y intercept. I'll use 0,3
y = mx + b
y = -1/4 x + b
3 = 0 + b
b = 3
Answer
y = -1/4 x + 3
1) Considering that there are 150 students
A) Adding 24+39 we got 63 students
150------------100%
63 ----------- x
x=6300/150
x= 42% of the students passed Math.
B) Adding the number of those students who live off-campus 39 +21
150 ----------------100%
60------------------ y
y=6000/150
y=40%
C) 60 students live off-campus 39 succeded. So we can write
60 --------- 100%
39 --------- z
z= 3900/60
z=65% passed math (off-campus)
D) Comparing that 65% of students who live off-campus passed math and that among those who live on campus and that 58% of all students failed
Then we can state:
A)
Answer:
-16x - 7b - 2800X + 35000
