Answer: B) 2lb
Step-by-step explanation:
First, you must convert from mixed numbers to fractions, as following
Point diagrams divide a sample into different classes, and allow to observe the frequencies of each class.
In this case, the different weights of the grapefruit constitute the classes. From a sample of 9 grapefruit, some will weigh others weigh , etc.
We need to observe the dot diagram to know how many grapefruit we have and how many grapefruit we have. In other words, we need to know, in the diagram, how many points there are about class and how many points there are about class
Then, the total difference between all grapefruit of pounds and all grapefruit of pounds is calculated as follows:
n () - m () = W
Where
W: Weight difference
n: Quantity of grapefruit
m: Quantity of grapefruit of
Suppose that of the 9 total grapefruits, 3 of them weigh pounds and 2 of them weigh pounds. This is: n = 3 and m = 2
The difference in weight would be 2 pounds.

then
For
C. When will the ball hit the ground?
The ball will hit the ground when
so,
Using the quadratic equation
Answer:
7n-2
Step-by-step explanation:

Let N be the number of additional no-hitter innings. Then to break the record they need:
87 + N ≥ 112
or
N ≥ 25
Which means they need at least 25 or more no-hitter innings to break or tie the record.
So for the two equations: Not sure how hard you want them but....
15+1=16 and 13+ 18=21
For the open equation.
2x + x(5+7)=105
