Answer:
To find the sum of interior angles in a polygon, we can use the formula:
where n is the number of sides.
Since this is pentagon (5 sides), then
The missing angle would then be
Since angles on a straight line add up to 180, then
What is the answer to this expression 0.6(d+3)=3d

The table is missing in the question. The table is provided here :
Group 1 Group 2
34.86 64.14 mean
21.99 20.46 standard deviation
7 7 n
Solution :
a). The IV or independent variable = Group 1
The DV or the dependent variable = Group 2
b).
Therefore,
t = -2.579143
Now,
df = 7 - 1
= 6
Therefore the value of p :
= 0.020908803
The p value is 0.0209
So we reject the null hypothesis and conclude that
