Answer:
x = 39
Step-by-step explanation:
there is a theorem that states that the midsegment in a trapezoid is equal to the sum of the bases divided by two
so, (36 + 42)/2 = x
36 + 42 = 78
78/2 = 39
<span>Divide the US into groups, by state. For cluster sampling, randomly choose twenty states and use the population of those states as the sample. For stratified sampling, randomly choose 10,000 people from every state as the sample.</span>
Area is length times width. so 3.5 * 3 would be an area of 10 and a half
Answer:
HIG=28°
Step-by-step explanation:
HI is a diameter therefore it's measure is 180°
HI-IG=HG
180-128=HG
52°=HG
HIG=1/2HG
HIG=1/2(56°)
HIG=28°
Answer:
Standard deviation =2.6
Step-by-step explanation:
Using the formula given
S = √((1/n-1)∑(x-x⁻)²)
n = 5
∑(x-x⁻)² = 34
Therefore;
s = √(1/5(34)
= √6.8
<u> = 2.6 </u>
The standard deviation will be 2.6
