Hey there,
Your question states: <span>These are 2-dimensional shapes. They are made of straight lines, and the shape is “closed” (all the lines connect).
</span><span>The correct answer would be Polygon. Polygons are the shapes with a </span> 2-dimensional shapes, and has straight lines.

Answer:
B) 53x + 74
Step-by-step explanation:
(59x + 64) - (6x - 10) = 59x + 64 - 6x + 10
= 53x + 74
For this problem, the confidence interval is the one we are looking
for. Since the confidence level is not given, we assume that it is 95%.
The formula for the confidence interval is: mean ± t (α/2)(n-1) * s √1 + 1/n
Where:
<span>
</span>
α= 5%
α/2
= 2.5%
t
0.025, 19 = 2.093 (check t table)
n
= 20
df
= n – 1 = 20 – 1 = 19
So plugging in our values:
8.41 ± 2.093 * 0.77 √ 1 + 1/20
= 8.41 ± 2.093 * 0.77 (1.0247)
= 8.41 ± 2.093 * 0.789019
= 8.41 ± 1.65141676

Let x = total games played
16% = 0.16
0.16x = 40. Divide each number by 0.16.
x = 250

Answer:
50
Step-by-step explanation:
its a straight line so all the angles have to add up to 180
