Answer:

Step-by-step explanation:

There are 40 trials, 16 out of those 40 trials resulted in two heads and one tail, which is what we are trying to find out of 120..

To do that, find 16/40 which gives you 0.4%

Next multiply 0.4% by 120 and you will get 48.

Hope this helped!

The graph of f "(x) is continuous and decreasing with an x-intercept at x = 0. Which of the following statements is true?

kari74 [83]

Answer:

The graph of f has an inflection point at x = 0.

Step-by-step explanation:

An inflection point occurs when the second derivative changes signs. Since f"(x) is decreasing and has an x-intercept at 0, it changes signs from + to -, so there is an inflection point at x = 0.

The measure of an angle exceeds 3 times its supplement by 4. Find the measure of the angles.

Dafna11 [192]

X=3y+4, y=y
x+y=180, 3y+4+y=180, 4y+4=180
4y+4=180
4y=176
y=44
x=3(44)+4, x=132+4, x=136
