Answer:
C
625
Step-by-step explanation:
We must first find the length of the side
So remember that the area of a square is side squared
So to find the length of the side we square root A
Since the perimeter of a square is 4 times the side we end up with 4square root(A)
And the whole thing must equal less than 100
So its C
Answer:
No, because the interval contains 0.96.

This is a problem of Binomial Probability.
Success Rate = p = 0.48
Sample Size = n = 55
Number of success = x = 22
We are to find

i.e. that probability that atleast 22 adults use the smartphone in meetings or class.
The probability can be calculated using the Binomial Calculators and it comes out to be 0.907.
This means there is
0.907 or 90.7% probability that there are atleast 22 adults among the 55 selected adults who use cell phones in meeting or class.
Answer: About 3.06
Step-by-step explanation:
We can use trigonometry functions to solve for AC. Let the ?, representing AC, be "x" in our mathematical work.
Since we have the hypotenuse and x is adjacent to the angle given, I am going to use cosine.
cos(θ) = 
cos(40) = 
0.766 ≈ 
3.06 ≈ x
x ≈ 3.06
