1 + 4 = 5

2 + 5 = 7 but you have to add the 5 from the previous addition problem, and it'll give you 12

3 + 6 = 9 but you have to add the 12 from the previous addition problem, and it'll give you 21

If you continue the pattern (4+7, 5+8, 6+9, 7+10) then 8 + 11 will be 96.

For ten school days, the numbers of bikes parked at a school bike rack are 10, 12, 8, 11, 13, 9, 2, 1, 9, and 12.

The mean number is 8.7 and the outliers 1 and 2 reduce the mean value

<h3>How to determine the mean number?</h3>

The dataset is given as:

10, 12, 8, 11, 13, 9, 2, 1, 9, and 12.

The mean number is calculated using:

Mean = Sum/Count

So, we have:

Mean = (10+ 12+ 8+ 11+ 13+ 9+ 2+ 1+ 9+12)/10

Evaluate

Mean = 8.7

Hence, the mean number is 8.7

<h3>The outlier and how it affects the mean</h3>

Outliers are relatively far from other data elements of the dataset

In the given dataset, 1 and 2 are far from other data element.

So, the outliers are 1 and 2

Because 1 and 2 smaller than other data elements, they affect the mean by reducing the mean value

Examine this system of equations. Which number can be multiplied by each equation so that when the two equations are

andreyandreev [35.5K]

Answer:

15 times the first equation and -12 times the second equation

Step-by-step explanation:

we have

$\frac{3}{4}x+\frac{2}{3}y=6$ ------> first equation

$\frac{5}{8}x+\frac{5}{6}y=12$ ------> second equation

Multiply the first equation by 15 both sides

$(15)\frac{3}{4}x+(15)\frac{2}{3}y=6(15)$

$\frac{45}{4}x+10y=90$ -----> new first equation

Multiply the second equation by -12 both sides

$(-12)\frac{5}{8}x+(-12)\frac{5}{6}y=12(-12)$

$-\frac{60}{8}x-10y=-144$ -----> new second equation

Adds the two new equations

$\frac{45}{4}x+10y=90\\-\frac{60}{8}x-10y=-144\\-----------\\\frac{45}{4}x-\frac{60}{8}x=90-144$

The y-term was eliminated
