All you need to do is divide .88 by 6.8.
.88/6.8= 0.129 (round upt to .13 cents)
I hope this helps!
Step-by-step explanation:
(X+3)(2x_9)
3x+12_12=90_12
3x=90_12
3x=78
X=26°
21 hours
73.50 x 3.50 = 21 hours
Answer:
Step-by-step explanation:
Given that in a recent poll 1 of 1000 American adults, the number saying that exercise is an important part of daily life was 753.
Sample proportion = 
To find 90% confidence interval we must find std error of proportion first
As per central limit theorem, sample proportion will follow a normal distribution with mean = 0.753
Std error of proportion= 
90% Z critical value = 1.645
Margin of error = 1.645*0.01363 = 0.0224
Confidence interval lower bound = 0.753-0.0224=0.731
Upper bound = 0.775
Answer: 0.3048
