X + 13 = -4
x = -4 - 13
x = - 17
I am thinking it is the first one..solution is -17

Answer:
Radius: 7
Diameter: 14
Area Formula: π r^2
Area Answer: 154 ft^2
Step-by-step explanation:
Radius: 14/2 = 7
The radius is always half the diameter.
Area Work
A = π(7)^2
A = π(49)
A = 153.9380 ft^2
Answer:
1) B. The height appear to be reported because there are disproportionately more 0s and 5s.
2) A. They are likely not very accurate because they appear to be reported.
Step-by-step explanation:
The distribution table is shown below:
Last Digit Frequency
0 9
1 1
2 1
3 3
4 1
5 11
6 1
7 0
8 3
9 1
1. Based on the distribution table, we see a very disproportionate distribution. There is a high frequency of 0's and 5's. This lays credence to the heights being reported rather than measured. As such, option B is the correct answer
<u>B. The height appear to be reported because there are disproportionately more 0s and 5s</u>.
2. Since the heights were reported and not measured, they are most certainly not accurate. The conclusion is that the result is not accurate. As such, option A is the correct answer
<u>A. They are likely not very accurate because they appear to be reported</u>.

Answer:
x = 31
Step-by-step explanation:
The sum of angles in a triangle is 180°.
98° +51° +x° = 180°
x° = 31° . . . . . . . . . . . . subtract 149°
x = 31
