Answer:
2
Step-by-step explanation:
x f(x)
−3 −1.5
−2 −1
−1 −0.5
0 0
1 0.5
2 1
3 1.5
This table shows the input and output values for a linear function f(x).
Now, two inputs which are four values apart are say -3 and 1 and the corresponding outputs are - 1.5 and 0.5.
Therefore, the positive difference of outputs is [0.5 - (- 1.5)] = 2 (Answer)
Domain and Range both are real numbers for all odd-degree polynomial functions.
Writing in an Interval Form, note that we use the least value in the left and the most value in the right.
From [a,b], [a,b), (a,b] or (a,b) | a must be less than b.
Therefore, the D choice is wrong in Interval part (However, right in range and domain but just for interval order.)
So the answer is C.
Answer:
48
Step-by-step explanation:
The fraction who picked apples is the rest of the students:
1 - 5/8 = 3/8
of them.
So the number who picked apples relative to the number who picked bananas is ...
apples/bananas = (3/8)/(5/8) = 3/5
Multiplying this by the number who picked bananas gives the number who picked apples:
apples = bananas · 3/5 = 80·3/5 = 48
48 students picked apples.
____
<em>Alternate solution</em>
Let "a" represent the number who picked apples. The ratio of banana choosers to the total is 5/8, and there were 80 who chose bananas. That gives rise to the equation ...
80/(80 +a) = 5/8
640 = 400 +5a . . . . . . multiply by 8(80+a) and simplify
240 = 5a . . . . . . . . . . . subtract 400
240/5 = a = 48 . . . . . . divide by 5
48 students picked apples.
It would be 81 because in decimals the whole number is before the decimal point and since 6 is greater than 4 (1 through 4 round down and 5 through 9 round up)you would round up the 80 to make it 81
