HELP HELP HELP HELP FIND THE VALUE OF X
aalyn [17]

Answer:

x=9

Step-by-step explanation:

The sum of all three angles inside a triangle is always 180 and the small square in the bottom left corner means that that is a 90 degree angle.

90+5x+5x=180

add the x values together

90+10x=180

subtract 90 from both sides

10x=90

divide both sides by 10

x=9

Find the average distance each data value in the set is from the mean. Round your answer to the nearest tenth, if necessary. Pri
sineoko [7]

Answer:

The average distance of each observation from the mean is 0.                

Step-by-step explanation:

We are given the following in the question:

$7, $20, $9, $35, $12, $15, $7, $10, $20, $25

Formula:

Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}

Mean =\displaystyle\frac{160}{10} =16

Difference from the mean value of each term:

-9, 4, -7, 19, -4, -1, -9, -6, 4, 9

Average distances =

\text{Average distance} =\displaystyle\frac{0}{10} =0

Thus, the average distance of each observation from the mean is 0.

Marianna [84]

Answer: Someone tell me if i'm wrong but from this I think it might be the fourth one (?)

Step-by-step explanation:

y=1

A straight line in slope (m) and intercept (c) form is:y=mx +c

In this example, y is a straight line of slope 0 and y −intercept of 1 ∴ y =0⋅  

x+1

Hence, the graph of y  a is straight line parallel to the x −axis through the point
