Answer:
The fastest runner is Alana because she had the least mean running time. The most consistent runner is Lorena because she had the least interquartile range value.
Simply collect all the like terms together
So..3+5+14 is 22x
The ratio a:b is 3:8
Step-by-step explanation:
In simple words, the ratio a:b means the fraction a/b.
So we will have to solve the given equation for a/b
Given

Dividing both sides by 8

Dividing both sides by b

The ratio a:b is 3:8

Answer:
s=P-b/2
Step-by-step explanation:
P-b=2s
P-b/2=s
Lets say that the two unknown integers are

and

.
We know the following things about

and

:


And, we want to find

.
To solve this, we'll use the expansion of the squared of the sum of any two inegers; this is expressed as:

So, given what we know about the unknown integers, the previous can be written as:

We can easily solve for

:
The answer is 168.
Another approach to solve the problem is, from the two starting equations, compute the values of

and

, which are 12 and 14, and directly compute their product; however, the approach described is more elegant.
