Answer:
a)False: In a sample of 100 men who are heavy smokers, exactly 24 of them will contract lung cancer.
b)True: In a sample of 100 men who are heavy smokers, the number who will contract lung cancer is likely to be close to 24.
c)True: As more and more heavy-smoking men are sampled, the proportion who contract lung cancer will approach 0.24. Circle one: TRUE FALSE
Answer:
The average rate of change of the function over the interval is of 6.
Step-by-step explanation:
Average rate of change:
The average rate of change of a function h(x) over an interval [a,b] is given by:
In this question:
Over the interval [-9,-2], so 
The function is:
Then
The average rate of change of the function over the interval is of 6.
Answer:
B
Step-by-step explanation:
For the divisor on the left of the division symbol, the -3 symbolizes that the -3 is a root. This means that when we plug -3 into our divisor, the answer is 0. Therefore, as x+3=0 when x=-3, the divisor is x+3.
Next, for the dividend, we can start on the left with no x multiplied to it and then add one degree of x for each value to the left. This results in
6 + -4 * x¹ + 4 * x² + 2 *x³
= 2x³ +4x² -4x+6
1 has the greatest value, it's worth 100,000,000 or 100 million.
Answer:
f(3) = 8
Step-by-step explanation:
f(x) = 5x - 7
Put x as 3 and evaluate.
f(3) = 5(3) - 7
f(3) = 15 - 7
f(3) = 8
