Let x = liters 20% solution to be added
then
.12(12) + .20x = .14(12+x)
.12(12) + .20x = .14(12+x)
1.44 + .20x = 1.68 + .14x
.20x = .24 + .14x
.06x = .24
x = 4 liters

Answer:
The Z score for this test is 1.3416
Step-by-step explanation:
According to the data given:
Null Hypothesis is: H0: p = 0.5
Alternative Hypothesis is: Ha: p > 0.5
Here the firm found 265 out of 500 heard pf the phone
p-cap = 265/500 = 0.53
n (sample size) = 500
Therefore, z = (p-cap – p)/√{p*(1-p)/n}
= (0.53 – 0.5)/√(0.5*0.5/500)
= 0.03/√(0.0005)
= 0.03/0.02236
= 1.3416
The Z score for this test is 1.3416
4/5- 0.8
9/25-0.36
1/10-0.1
7/25-0.28
You divide the numerator by the denominator 4/5 = 4 divided by 5=0.8
45/ 100
There are 45 shaded squares , there is a total of 100 squares , the total is the denominator and the numerator is the total of shaded squares .
