Answer:
Margin of error = 0.01344
Step-by-step explanation:
Margin of error = critical value × standard deviation.
critical value for 95% confidence interval = 1.96
Standard deviation = √[(p)(q)/n]
p = 0.4, q = 1 - p = 1 - 0.4 = 0.6, n = 5100
Standard deviation = √[(0.6×0.4)/5100] = 0.00686
Margin of error = 1.96 × 0.00686 = 0.0134
a x a x a x a x a x a
a^4 x a^2
a x a x a x a times a x a
= a^6 or a x a x a x a x a x a
11/84
Simplify 7/8 +2/3 to 37/24
4/7 × 37/24 -3/4
Use this rule: a/b x c/d = ac/bd
4 x 37 - 3
7 x 24 - 4
Simplify 4 ×37 to 148
148/7 x24 - 3/4
Simplify 7 ×24 to 168
148/168 - 3/4
Simplify 148/ 168 to 37/42
37/42 - 3/4
Simplify.
anddd the answer is
40
h(x)= 4(x + 6)
Let x=4
h(4)= 4(4 + 6)
= 4(10)
= 40
18,000
Step-by-step explanation: Multiply 45 by 400 to find the total number of gallons of water used daily
45 x 400 = 18,000
