Answer:

see explanation

Step-by-step explanation:

To obtain the quartiles arrange the data in ascending order

38, 47, 54, 60, 67, 68, 76, 77, 84, 89

Q₂ is the median

The median is the middle value in the data set. If there is no exact middle value then it is the average of the 2 values either side of the middle

Q₂ = \frac{67+68}{2} = 67.5

Q₁ is the lower quartile and is the middle value of the data to the left of the median

Q₁ = 54

Q₃ is the upper quartile and is the middle value of the data to the right of the median

Q₃ = 77

Lower quartile=25% of total frequency/numbers in the data set

Median=50% of total frequency/numbers in the data set

Upper quartile=75% of total frequency/numbers in the data set

Hope this helps:)

Answer:

x = -0.8

<CAD = -8

Step-by-step explanation:

10x + 4 = 5x - 4 (Clean up)

10x = -8 (Divide each side by 10)

x = -0.8

<CAD = 5x - 4

<CAD = 5(-0.8) - 4

<CAD = -4 - 4

<CAD = -8

In January Jennifer was allowed to use 150 text messages. If she is allowed to use the same amount of text messages every month.
Firlakuza [10]

She would have used 1200 messages in all by the month of August.

Step-by-step explanation:

Messages allowed per month = 150

There will be 8 months starting from January to August, therefore,

Time period = 8 months

Messages in 8 months = Messages per month * Time period

Messages\ in\ 8\ months=150*8\\Messages\ in\ 8\ months=1200

She would have used 1200 messages in all by the month of August.
