Answer:
I think the answer is 3.
Step-by-step explanation:
First make arrow diagram of function f and g.
Then show it as composite function of fog(x) in arrow diagram.
Then in range you find -8 whose domain as x is 3.
Answer:
H0: p = 3.5
H1: p < 3.5
Step-by-step explanation:
We are told that past studies have indicated that the percentage of smokers is estimated to be about 35%, but with the new smoking cessation programs that have been implemented, it is believed that the percentage of smokers has been reduced, we must propose our null and alternative hypotheses, which would be the following:
Null hypothesis: H0: p = 3.5
Alternative hypothesis: H1: p < 3.5
Answer:
2, 1, 3, 4
Step-by-step explanation:
For future reference:
Make all the numbers (accept for the second one) into a common form. For example a decimal.
For the first one, it will simplify into 3/2 since both 9 and 4 can be easily rationalized.
The second can't be written as a decimal, but it will easily become the least greatest number.
The third is already a decimal and the fourth could just be divided 5/3 using a calculator.
From there you'll have
1.5, /5, 2.5, and 1.67
Answer:
Set one: 12 and 13
Set two: -13 and - 12
Step-by-step explanation:
Let the smaller number = x
Let the larger number = x + 1
x^2 + (x + 1)^2 = 313 Remove the brackets on the left.
x^2 + (x^2 + 2x + 1) = 313
x^2 + x^2 + 2x + 1 = 313 Collect like terms
2x^2 + 2x + 1 = 313 Subtract 313 from both sides
2x^2 + 2x + 1 - 313 = 313 - 313
2x^2 + 2x - 312 = 0 Divide by 2
x^2 + x - 156 = 0
factor
There are two sets of factors that work
Set One
x = 12
x + 1 = 13
Set Two
x = - 13
x+1 = -13 + 1 = - 12
The second set is where you will get your marks. Few people will remember to use the minus answer
Answer:
option D. x = 1 3/5
Step-by-step explanation:
ratio and proportion
<u> 4 </u> = <u> x </u>
5 2
X multiply:
5x = 4(2)
5x = 8
x = 8 / 5
x = 1 3/5
