Answer:
30.0
Step-by-step explanation:
Given our data is normally distribute with 
and 
-Top 7% is given by find the z-value corresponding to p=(1-0.07)=0.93
-We substitute our values in the equation below;
Hence, the minimum score required for the scholarship is 30.0
Answer:(5 + x)(2x + 10)
Step-by-step explanation:
Im pretty sure its that
So 16 = 3.6, 10 = 2.3 so 20 = 4.6 then add 16 + 20 to get 36 so 3.6 + 4.6 = 8.2
36 ounces = 8.2 cups
36 = 8.2, 8 = 1.8, 20 = 4.6, 36 + 8 + 20 = 64 ounces so 8.2 + 1.8 + 4.6 = 14.6 cups
64 ounces = 14.6 cups
Total cups = 8.2 + 14.6 = 22.8 cups
Answer:
x= -7
Step by Step Explanation:
We can write them both like functions like this
A= 5x- 4
B= 3x+ 8
The output of A will be three times the output of B
A=3b
We replace with the functions
5x-4= 3
We solve for x
5x= -4= 9x + 24
5x- 9x= 24 + 4
-4x= 28
x= 28 - 4
x= -7
The output that makes the out put of A 3 times the output of B is -7

To find equivalent ratios just factor the same number to both numerator and denominator. I will make the ratios simple by multiplying 2/2 and 3/3 to the originals. To check, set as fraction and cross multiply and you should have the same number. I will show you how to check by doing it to the first ratio.
8:5 16:10 24:15
Check:
8/5 = 16/10
(8)(10)=(5)(16)
80=80
8/5=24/15
(8)(15)=(5)(24)
120=120
4:19 8:38 12:57
6:23 12:46 18:69
