Answer:
120,0.60,100
Step-by-step explanation:
Given that in a certain county in 2013, it was thought that 50% of men 50 years old or older had never been screened for prostate cancer.
Suppose a random sample of 200 of these men shows that 120 of them had never been screened.
a) the observed frequency = 120
b) The observed proportion of men who said they had not been screened
=
c) Expected number in the sample to say they had never been screened if 50% is the correct rate

The answer is D. The triangles have proportional sides (the triangle on the left has sides that are 4 times that of the triangle on the left). Since the triangles have proportional sides, the angles given will also be equal. Thus, we can show their similarity through both the SSS and SAS similarities.
The value of the initial investment is given when x = 0, so substituting x = 0 into the function, we have
C(0) = 3(0)²-2(0)+5
C(0) = 5
The initial investment is $5
I’m guessing it is 1 million because you can only round up since it’s value is not above 1 million.
3y=−4x+2
y = -4x/3 + 2/3
y = 3x/4 + 2/3
so the slope is 3/4 remember that perpendicular slope is just the opposite reciprocal of the original slope given.
