Answer:
B. A random sample of 2,800 U.S. adults under 35.
Step-by-step explanation:
To have an unbiased and accurate sample, the sample should be representative of the population about which we are inferring.
Also, the bigger the sample size, the less margin of error we will have in the inference.
As the population in this survey is about the US adults under 35, the sample should be selected from this group.
From the options that select from this population, the largest sample is 2,800.
So the answer is Option B.
There is nothing here. If they are both equilateral triangle‘s then I would say yes
Answer:
d
Step-by-step explanation:
Answer:
Solution given:
p=6in
b=8in
By using Pythagoras law
diameter=
=10in
r=5in
Now
Area of shaded region=area of semi circle- area of triangle
=½(πr²)-½p*b
=½(π×5²)-½(6*8)
=15.269
=15.3in² is a required answer.
