Answer:
0.13591
Step-by-step explanation:
What we do here is find a score of both values;
Mathematically;
z-score = (x - mean)/SD
for 825, we have (825-750)/75 = 1
For 900, we have (900-750)/75 = 150/75 = 2
So the probability we want to find is;
P(1<x<2) = P(x<2) - P(x<1)
We use the standard table for this and we arrive at;
P(1<x<2) = 0.13591
Let us assume the number of band members = x
Let assume the number of chorale members = y
Then
x = y + 30
(x + 10)/(y + 10) = 3/2
2(x + 10) = 3(y + 10)
2x + 20 = 3y + 30
2x - 3y = 10
Putting the value of x from the first equation in the second equation, we get
2x - 3y = 10
2(y + 30) - 3y = 10
2y + 60 - 3y = 10
y = 50
Putting y = 50 in the first equation we get
x = 50 + 30
= 80
From the above deductions, we can easily conclude that the number of band members is 80. I hope that this is the answer that has actually come to your help.
To reduce the fraction in its simplest form...first find the greatest common factor of the numerator and the denominator..so in this case is 8.
Now lets divide the numerator by the GMF;
16 ÷ 8 =
2 Next the denominator;
24 ÷ 8 =
3
So
Hope this helps! :D
Answer:
0 and 3, right? like look how everything else is set up
Step-by-step explanation:
1 4
2 5
3 6
4 7
they all add one to each number every problem. So subtract 1 from both and that should be your answer.
It’s function because non of the lines touches twice.
