Find the mean and the median of this data set: 8, 6, 6, 3, 55, 7, 5, 2. The mean is and the median is .

The mean is 11.5

The median is 6

Step-by-step explanation:

First put all the terms in order from smallest to largest

2, 3, 5, 6, 6, 7, 8, 55

The mean is the average. To figure the mean add all the terms together and divide by the number of terms.

There are 8 terms

2+3+5+6+6+7+8+55=92

92/8=11.5

The median is the middle of all the terms. To figure the median find the middle two terms and find their average.

Hint: If the middle two terms are the same number, the median is that number.

The middle two terms are 6 and 6 so the median is 6

the answer is d

step-by-step explanation:

y+3=-4(x-2)

y+3=-4x+8

  -3         -3  

y=-4x+5

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
