Answer:
So, the interval is : (7.206,7.794)
Step-by-step explanation:
The mean μ = 7.5
Standard deviation σ=3
n = 400
At 95% confidence interval, the z score is 1.96

And 
7.5+0.294 and 7.5-0.294
So, the interval is : (7.206,7.794)
The answer is 20.25 because .9 squared is .81 so you times .81 to 5 squared and you get 20.25
Answer:
<em>x=8</em>
Step-by-step explanation:
<u>Triangles</u>
An isosceles triangle is a triangle with two equal sides. The angles the equal sides form with the third side are also equal.
The triangle shown in the figure is isosceles and the angles marked as '2' and 67° are equal. But we are also given that the angle '2' equals 8x+3, thus:
8x+3=67
Reducing:
8x=67-3=64
Solving:
x=64/8
x=8
Answer:
6r+7=13+7r
6r+7=7r+13
6r+7−7r=7r+13−7r
−r+7=13
−r+7−7=13−7
−r=6
= 
r=−6
