Answer:
Step-by-step explanation:
To solve this problem we need to be familiar with the formula for the surface area of a cone:
We are given the length of a side and the diameter, to calculate the radius divide the diameter in half:
To calculate the height of the cone, we must use the Pythagorean Theorem:
We can treat the side length as the hypotenuse 
, the radius as the base 
, and solve for height 
. Set the expression up like this:
Now we can plug into our original formula:
Answer:
B.0.15
Step-by-step explanation:
To approximate a binomial distribution as a normal distribution, two conditions must be met:
np > 10
nq = n (1−p) > 10
Here, n = 250. Check each value of p to see if it meets the conditions.
A. p = 0.03
np = 7.5, nq = 242.5
B. p = 0.15
np = 37.5, nq = 212.5
C. p = 0.02
np = 5, nq = 245
D. p = 0.97
np = 242.5, nq = 7.5
E. p = 0.99
np = 247.5, nq = 2.5
Of the five choices, only B meets both conditions.
Answer:
B) Reflection
Step-by-step explanation:
The two figures mirror each other.
5700 is 5731 rounded to the nearest hundred
Multiply both sides by 2200/1760 * 2200/1760 and you get 1.25
