30
Step-by-step explanation:
Answer:
if you are asking what the measure of the other angle is if it's just two angles and they are supplementary, the answer is 145º
Step-by-step explanation:
Supplementary angles would add up to equal 180º.
Angle W, which we already know is 35º.
Let's just call the other angle "x" for now.
1. Since we know the two angles will equal 180º, we can do x + 35= 180
2. Now we have the equation set up, and we can subtract 35 from each side
3. Once you subtract 35 from each side, you get x = 145º, which is your answer!
Answer:
160 Seconds or 2 minutes and 45 seconds
Step-by-step explanation: So 6.4x25=160 seconds or 2 min 45 sec
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
