Pi feet squared (I hope I helped!)
Answer:
x/6
Step-by-step explanation:
Use x to represent "a number" bc u dont know exactly what that number is.
Answer:
Option C is correct.
The test statistic for this question is -3.13
Step-by-step explanation:
To compute the z-test statistic, the formula is given as
z = (x - μ₀)/σₓ
x = p = sample proportion of the 500 college students sampled, that favor reducing the deficit using only spending cuts with no tax increase = (75/500) = 0.15
μ₀ = p₀ = the proportion to be compared against, that is, the proportion of Americans that favor reducing the U.S. budget deficit by using spending cuts only, with no tax increases = 20% = 0.20
σₓ = standard error of the sample proportion = √[p(1-p)/n]
p = 0.15
n = Sample size = 500
σₓ = √[0.15×0.85/500] = 0.01597
z = (0.15 - 0.20) ÷ 0.01597
z = -3.13
Hope this Helps!!!
2(z-10)=-4
2z-20=-4
2z=16
z=8
1 percent of $270 is 2.70 (you just move the decimal point). then multiply your 1 percent by 24 and you have the answer. I get $64.80, doing it on paper.
Add the 24 percent to the original price and you have your retail price: $334.80. If you have a calculator, check my maths.
