Answer:

49 and 26

Step-by-step explanation:

every triangles angles equal 180 degrees 76 + 55 equals 131. 180 - 131 = 49. the 2nd question has a small square at the bottom part of the triangles and those always mean 90 degrees. 64 + 90 = 154. 180 - 154 = 26.

The mean of a data sample can be found by adding all the terms in the data sample and dividing the result by the number of terms. In the first case we have the following data sample:

12,8,15,11,9

The mean of this sample is:

\operatorname{mean}=\frac{12+8+15+11+9}{5}=\frac{55}{5}=11

The mean absolute deviation is the sum of the differences between each data value and the mean, divided by the number of data values, the formula is:

MAD=\frac{\sum ^{}_{}\mleft|x_i-\bar{x}\mright|}{n}

Therefore, we must calculate the positive difference between each value and the mean, add them up, and divide the result by the number of data points in the sample. In the case of the first sample we get:

\text{MAD}=\frac{(12-11)+(11-8)+(15-11)+(11-9)}{5}

Solving the operation:

\text{MAD}=\frac{10}{5}=2

If done this way, all the results for each data set must be correct.

Write the equation of a line that<br> goes through the point (-2, 3)<br> with a slope of 2.
bezimeni [28]

Answer:

y = 2x + 7

Step-by-step explanation:

y = mx + b  The point (-2,3) gives us an x value and a y value that we can use.  We are also give the slope (m).  All we need to do is figure out the b (y-intercept) value.

y = mx + b

3 = 2(-2) + b

3 = -4 + b  Add for to both sides

7 = b  We know have every thing that we need to write the equation.  We have the slope (m) which is 2 and the b (y-intercept) that we just figured out is 7

y = 2x + 7

Solve the inequality. 1/2 + x + 1/6 is greater than or equal to 1.
Andrew [12]

1/2 + x + 1/6 > = 1

First add the 2 fractions:

1/2 + 1/6 = 2/3

Now you have:

2/3 + x > =1

Subtract 2/3 from both sides:

x >= 1 - 2/3

X > = 1/3
