Given:
mean = 64
standard deviation = 6
sample size = 50
Standard error of the sample mean = standard deviation / √sample size
Standard error = 6 / √50 = 6/7.07 =<span> 0.85</span>
Answer:
<h2>A) 67</h2>
Step-by-step explanation:
The sum of the angles measures at one side of the parallelogram is 180°.
Therefore we have the equation:
x + 113 = 180 <em>subtract 113 from both sides</em>
x + 113 - 113 = 180 - 113
x = 67
Ok so first following the order of opperation (P.E.M.D.A.S.)
We have to multiply first so 1/4*4/9 is 4/36
2/3-4/36
We have to get them both to have the same denominator
What times 3 is 36? 12
So multiply 2*12 and 3*12 you get
24/36-4/36=5/9(simplified)
Answer:
A. Height of the Flag pole
B. Longest.
Explanation:
Two similar triangles have corresponding sides with the same ratio.
A smaller triangle is showing the shadow of a person and the larger one is showing the shadow of a flag.
Now the person's shadow in the smaller triangle corresponding to the Height of the Flag pole.
The longest side of the large triangle corresponds with the Longest side of the smaller triangle.
