Answer:
B) 1/6
Step-by-step explanation:
If you roll a six-sided die twice the two times you roll you have a chance of getting an odd number the first time and an even number the second time.
Than would look like 2/12.
2/12 simplified is equal to 1/6.
So,this means the answer is 1/6.
Hope this helps!
Let's start with the question, how many questions do you need to get 88%?
so were are looking for
?/25 = 88% and 88% is also 0.88 so we can multiply 25 by 0.88
we get 22
But this doesn't here. the question asks us how many mistakes do you need. you can just subtract 22 from 25
25-22= 3
you need 3 misses to get 88%
Answer:
21. d. 39
22. c. 20; 7
Step-by-step explanation:
21. This is straightforward evaluation of the function. Put the numbers 8 and -5 where x is in the function definition and do the arithmetic. Then find the difference of the results.
f(8) = 3·8 -2 = 22
f(-5) = 3·(-5) -2 = -17
f(8) - f(-5) = 22 - (-17) = 22 +17 = 39

22. The first part is similar to 21—evaluate the function for x=2.
f(2) = 24 -2·2 = 24 -4
f(2) = 20
Note that this result is sufficient to allow you to choose the correct answer.
However, we can also do the second part. Find x for f(x) = 10
f(x) = 24 -2x
10 = 24 - 2x . . . . . . substitute 10 for f(x)
-14 = -2x . . . . . . . . . subtract 24 from both sides
7 = x . . . . . . . . . . . . . divide both sides by -2
The equation of the line is y= 3x
