2/5 (2x - 12) = -28 Can You Help Me?
Answer 2

Answer:

x = - 29  

Step-by-step explanation:

2 5 ( 2 − 1 2 ) = − 2 8

2 ( 2 − 1 2 ) 5 = − 2 8

4 − 2 4 = − 1 4 0

4 − 2 4 + 2 4 = − 1 4 0 + 2 4

2 ( 2 − 1 2 ) 5 = − 2 8

4 − 2 4 5 = − 2 8

4 − 2 4 5 = − 2 8

5 ⋅ 4 − 2 4 5 = 5 ( − 2 8 )

4 − 2 4 = − 1 4 0

4 − 2 4 = − 1 4 0

4 − 2 4 + 2 4 = − 1 4 0 + 2 4

4 = − 1 1 6

4 = − 1 1 6

4 4 = − 1 1 6 4

= − 2 9

Answer:

The following dot plot represents the litter sizes of a random sample of labrador retrievers.



Calculate the mean, median, and mode for this set of data.
Calculate the range, interquartile range, and mean absolute deviation (rounded to the nearest hundredth) for this set of data. For the mean absolute deviation, do not round the mean.
Make two inferences about the litter size of labrador retrievers.

Answers

Answer:

The mean, median, and mode for this set of Data is:  

Mean =7.78

Median = 8

Mode: 7

The range, Interquartile range, and the 'MAD' for this set of data is:

Range = 9

Interquartile range: = 2

MAD: 6.5 (not rounded to the nearest 100th)

Make two inferences about the litter size of Labrador retrievers.

The range size of Labrador retrievers is approximately 4 times larger than the interquartile range. The mean is approximately two times more than the MAD.

2 x 3/8 as a fraction in simplest form

Answers

Answer: 3/4

Step-by-step explanation: Think of the 2 in this problem as 2/1.

So we have 2/1 x 3/8 and notice that we can

cross-cancel the 2 and 8 to 1 and 4.

Multiplying across the numerators and denominators, we have 3/4.

When multiplying two fractions together,

always try to cross-cancel before multiplying if possible.

3/4 is the answer in simplest form
