Answer:
x = 133
Step-by-step explanation:
First, determine what total sum would be needed for the mean to be 114. Do this by multiplying 114 by 6 (bc total number of values in data set includes the variable <em>x</em>).
114 x 6 = 684
Next, add the five known values to get a sum of 551.
Now, just: 684 - 551 = 133
For the mean to be 114, x must equal 133.
Answer:
The rate of change for A is 4. For B, it is 2
Step-by-step explanation:
the slope of A is 4 and for B it is 2. Slope is the same as rate of change.
D should be the correct answer

Answer:
x=7 units
Step-by-step explanation:
see the attached figure with letters to better understand the problem
we know that
The triangles AMN and APQ are congruent by SAS similarity postulate
The include angle
∠MAN=∠PAQ
Because
Arc MN=Arc PQ
therefore
MN=PQ
substitute the values
38=4x+10
solve for x
4x=38-10
4x=28
x=7 units
