The margin of error of a sample is given by:
B = z(α/2) σ/√n; where B is the margin of error = 25, z(α/2) is the level of significant = 1.96, σ is the standard deviation = 100 and n is the sample size.
25 = 1.96(100/√n)
100/√n = 25/1.96 = 12.76
√n = 100/12.76 = 7.84
n = (7.84)^2 = 61.47
Therefore, the smallest sample size required is 62 seniors.
Answer:
Depends on area
Step-by-step explanation:
Area of 1 greater than 2 than 3 than 4
Answer:
A.x+4
Step-by-step explanation:
We are given that a rational function which has a vertical asymptote at x=-4.
We have to find the term which appears in factored form in the denominator of the function.
We know that
To find the vertical asymptote of a rational function we will substitute the
denominator equal to zero.
Then, solve for x.
The value of x obtained are called vertical asymptotes.
By definition of vertical asymptote
x=-4
x+4=0
x+4 will be appears in factored form in the denominator of the function.
Answer:
36 = x
Step-by-step explanation:
The triangles are congruent by Side Angle Side, so the angles must measure the same
Angle C = Angle E
36 = x
-4 - 7 divide 8n thats the answer
