Answer: A, 12
Step-by-step explanation:
The line in the middle is a midsegment, making the two triangles similar by a ratio of two. So, dividing 60 by five will give you twelve
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!!!
That is basically 5 - 2 I believe so the answer is 3.
Answer:
B = (A - 6) / 10
Step-by-step explanation:
This problem has 2 variables and 1 equation so it is not trivial to solve with confidence the value of B; however, we can solve for B in terms of A. With that being said, let's start.
If A divided by B = 10:
A/B = 10
10 remainder of 6
Could also be written as 10 & 6/B since B is the divisor. Rewrite this, you can get the equation:
A/B = (10B + 6) / B
A = 10B + 6
A - 6 = 10B
B = (A - 6) / 10
Thus, you have solve B in terms of A.
Cheers.
Answer:
x = ±1/2
Step-by-step explanation:
x^2-1/4=0
Add 1/4 to each side
x^2 -1/4+1/4 = 0+1/4
x^2 = 1/4
Take the square root of each side
sqrt(x^2) = sqrt(1/4)
x = ±1/2
