3/10+ 2/5
= 3/10+ 4/10 (common denominator is 10)
= 7/10
The final answer is 7/10~
All it's asking is: How many cubic inches are there in 22 gallons ? And it already GAVE us the conversion factor !
The conversion factor is . . . . . 1 gallon = 231 cubic inches
Multiply each side by 22: 22 gallons = 22 x (231 cubic inches)
22 x 231 = 5,082
22 gallons = 5,082 cubic inches
If you empty a full 22-gallon tank out through that flow meter, the meter will register 5,082 cubic inches when the tank is empty.

Answer:
0.12 ± 1.96 * √(0.12(0.88) / 100)
Step-by-step explanation:
Confidence interval :
Phat ± Zcritical * √(phat(1 -phat) / n)
Phat = 12/100 = 0.12
1 - phat = 0.88
Zcritical at 95% = 1.96
Hence, we have :
0.12 ± 1.96 * √(0.12(0.88) / 100)
0.12 ± 1.96 * 0.0324961
0.12 ± 0.0636924
Lower boundary = (0.12 - 0.0636924) = 0.0563
Upper boundary = 0.12 + 0.0636924 = 0.1837
Answer:
(2/3)y - (8/3) = x For the first one maybe?
Step-by-step explanation:
1. y = (3/2) x + 4
y - 4 = (3/2) x
(2/3)y - (8/3) = x
2. If output is 2, f(x) = 2.
So, 2 = (3/2) x + 4
-2 = (3/2) x
-4 = 3x
x = -3/4
