Answer:
-8
Step-by-step explanation:
The rate of change is found by
f(x2) - f(x1)
-------------------
x2 -x1
We know that f(x2) = -26 when x2 =5
And f(x1) = -10 when x1 = 3
-26 - (-10)
---------------
5 - 3
-26+10
---------------
2
-16/2
-8
So when you opened up the parenthesis on the right side of the question, you added -2 to 5 instead of multiplying. Since there is no addition sign in between -2 and the parenthesis, it should be multiplication, so -2x + -10.
So now the answer would be 10 = -10.
Which leads me to believe that this question wasn't written correctly because 10 does not equal -10 for sure.
.60 because there's 5 spots and 3 are odd so 3/5 is also equivalent to 60 percent? sorry if wrong!
The correct answer is C: -3b and 4b.
Answer:
The frequency of oranges is the classroom is 47.37%.
Step-by-step explanation:
The relative frequency of oranges is the number of oranges divided by the total number of fruits.
We have that:
8 students brought 2 apples each. So there are 8*2 = 16 apples
4 students brought an apple and an orange each. So there are 16 + 4*1 = 20 apples and 4*1 = 4 oranges.
7 students brough 2 oranges each. So there are 4 + 2*7 = 18 oranges.
There are 18 oranges, and 20+18 = 38 fruits in total.
So the frequency of oranges in the classrom is
