Answer:

134.38

This value represents 134.38

Step-by-step explanation:

Find the mean.

950+620+545+810+775+1120+905+775=6500

6500/8=812.5

Subtract the mean of numbers.

950-812.5=137.5

812.5-620=192.5

812.5-545=267.5

812.5-810=2.5

812.5-775=37.5

1120-812.5=307.5

905-812.5=92.5

812.5-775=37.5

Find the mean.

137.5+192.5+267.5+2.5+37.5+307.5+92.5+37.5=1075

1075/8≈134.38

This means that 134.38 is $134.38

MAD

To find the MAD of the data, you must first find the mean. To do this, simply add all the numbers up and divide by the number of data values.

950+620+545+810+775+1120+905+775=812.5

So the mean is 812.5 ($812.5).

The final step to finding the MAD is to difference between each data value and the mean.

|950-812.5| + |620-812.5| + |545-812.5| + |810-812.5| + |775-812.5| + |1120-812.5| + |905-812.5| + |775-812.5|

137.5 + 192.5 + 265.5 + 2.5 + 37.5 + 307.5 + 92.5 + 37.5/8

1073/8=9.625

So, 134.125 is the answer.

BUT... the question said round to the nearest cents. So, it's 13413 cents.

The eastbound train travels 10 miles per hour faster than the westbound train. After 2 hours, they are 232 miles apart. At what

patriot [66]

Answer:

48,58

Step-by-step explanation:

Let The speed of the west bound train be x

Let the east bound train be x+10

The speeds can be calculated as follows

2(2x+10)= 232

4x + 40= 232

4x= 232-40

4x= 192

x= 192/4

= 48

Hence the speedof the west bound train is 48

The speed of the east bound train is 48+10

= 58

Answer:

Step-by-step explanation:

(0, 4) (2, 0)

(0-4)/(2-0) = -4/2 = -2

y - 4 = -2(x - 0)

y - 4 = -2x + 0

y = -2x + 4

DO NOT SKIP!! Let’s see who’s smart enough to work out the problem if u get it correct I’ll mark u as BRAINLIEST SHOW THE WORK P

forsale [732]

Answer:

y=10.1(x)

x= $\frac{y}{10.1}$

Step-by-step explanation:

It is said in the problem that y would represent how much money she earns and x represents the number hours she works.

so it also said that the amount of Jessa earns is proportional to the amount of time she works .

finding y will be easy dividing 252.50 by 25 will give you 10.1

so how did we get that equation

y will represent the amount and x will represent the hours
