Answer:
just add 8+8+8 until you get to the number u want/need and the same with 7. Or you can multiply.
8x1=8
7x1=7
8x3=24 (8+8+8=24)
7x3=21 (7+7+7=21)
etc.
Hope it helps!
Add all of the interior angles to 1260. Then you simplify for x. After that you plug in what you found for X in the E expression.
Answer:
C =37.68 mm
Step-by-step explanation:
The circumference of a circle is given by
C = 2*pi*r
C = 2(3.14)*6
C =37.68 mm
Step 1. Find the Greatest Common Factor (GCF)
GCF = 7x^2
Step 2. Factor out the GCF (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
7x^2(14x^4/7x^2 + 35x^2/7x^2)
Step 3. Simplify each term in parentheses
7x^2(2x^2 + 5)
Answer:
90% confidence interval is (43.25, 61.41)
Step-by-step explanation:
Given that,
n = 17
Mean,
= 52.33
Standard deviation,
= 21.44
∝ = 0.10
Now,
Confidence interval =
± ![t_{\frac{\alpha }{2}, n-1} [\frac{\sigma}{\sqrt{n} } ]](https://tex.z-dn.net/?f=t_%7B%5Cfrac%7B%5Calpha%20%7D%7B2%7D%2C%20n-1%7D%20%5B%5Cfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%20%7D%20%5D)
= 52.33 ± 1.7646 [ 21.44 / √17 ]
= 52.33 ± 9.0791
So,
52.33 + 9.0791 = 61.4091
52.33 - 9.0791 = 43.2509
So,
90% confidence interval is (43.25, 61.41)
Also,
Lower end-point = 43.25
Upper end-point = 61.41
