(roughly equal to ~=)

Step-by-step explanation:

divide both sides by 1.35

12/1.35 = √x

square both sides to get rid of √

Victor is selling lemonade to raise money for his school.the amount of money he collected from his school. the amount of money h

motikmotik

The question is incomplete. The complete question is :

Victor is selling lemonade to raise money for his school. The amount of money he collected from his sales each day is summarized on the box plot below.

What is the interquartile range of the data ?

Answer:

$ 7

Step-by-step explanation:

It is given that Victor sold lemonade in order to raise money for his school.

The money that Victor collected is shown on the diagram below.

Therefore, we find the interquartile range. It is the difference between the 3rd quartile and the 1st quartile, i.e.

IQR = $Q_3-Q_1$

Now from the figure, the 3rd quartile is the value that is at the end of the rectangular box towards the right. Therefore, the 3rd quartile is = $ 29

Similarly from the figure the 1st quartile at the beginning of the rectangular box to the left is = $ 22

So the interquartile range is = 3rd quartile - 1st quartile

= 29 - 22

= $ 7

Thus the amount of money Victor collected is $ 7.

whitney has a coin jar with a small collection of nickels and dimes. there are 69 coins in the jar. they have a value of $5.90.

Anastaziya [24]

Answer:

The number of nickels in the jar is 20.

The number of dimes in the jar is 49.

Step-by-step explanation:

Let us assume the total number of nickels = x

The total number of dimes = y

Total coins = 69 coins

⇒x + y = 69

Now as we know:

1 Nickel = $0.05

and 1 Dime = $0.10

⇒ The value of x nickels = x ( $0.05) = 0.05 x

and The value of y nickels = y ( $0.10) = 0.10 y

Total amount in jar = $5.90 ⇒0.05 x + 0.10 y = $5.90

So, the given system of equation is

x + y = 69 .............. (1)

0.05 x + 0.10 y = 5.90 ....... (2)

Substitute the value of y = 69 - x in (2) , we get:

0.05 x + 0.10 y = 5.90 ⇒ 0.05 x + 0.10 ( 69 - x) = 5.90

or, 0.05 x + 6.9 - 0.10 x = 5.90

or, - 0.05 x = -1.00

⇒ x = 1/0.05 = 20, or x = 20

⇒ y = 69 - x = 69 - 20 = 49

Hence the number of nickels in the jar is 20

and the number of dimes in the jar is 49.
