Answer:
24/42
Step-by-step explanation:
2,5, 6, 8, 14
Answer:
4.
Step-by-step explanation:
First work out the mean:
Mean = (2 + 5 + 6 + 8 + 14) / 5
= 35/5 = 7.
Now subtract the mean form each of the values:
2 - 7 = -5
5 - 7 = -2
6 - 7 = -1
8 - 7 = 1
7 - 14 = -7.
The squares of these are 25, 4, 1, 1, 49
Their sum = 25 + 4 + 1 + 1 + 49 = 80
Now divide this by 5 = 16.
Standard deviation is √16 = 4.
Jada buys c/4.99 pounds of Blueberries.
A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
It is given that,
Cost of one pound of blueberries = $4.99
Blueberries bought by Jada = p pounds
Cost of p pounds of blueberries = c dollars
Now since cost of one pound of blueberries = $4.99
Therefore, Cost of p pounds of blueberries = p * $4.99
or, cost of p pounds of blueberries = $4.99p
Now since Jada pays c dollars for p pounds
⇒ c dollars = $4.99 p
⇒ p = c/4.99
Hence,Jada buys c/4.99 pounds of Blueberries for p dollars.
