Answer: -1
Step-by-step explanation:
Answer:
Confidence interval: (1760,1956)
Step-by-step explanation:
We are given the following information in the question:
Sample size, n = 81
Sample mean =

Population standard deviation =

Confidence Level = 95%
Significance level = 5% = 0.05
Confidence interval:

Putting the values, we get,


Answer:
y = 130(24/13)^(x -10)
Step-by-step explanation:
The y-value changes by a factor of 240/130 = 24/13 for a unit change in the x-value. This means we can write the function as though it had an initial value of 130 and a growth factor of 24/13, translated 10 units to the right.
y = 130(24/13)^(x -10)
_____
<em>Additional comment</em>
This can also be written in the form ...
y = a·e^(kx)
where a=130·(24/13)^(-10) ≈ 0.28266, and k=ln(24/13) ≈ 0.61310
Answer:
The answer of this question is 78°.
Step-by-step explanation:
Let angle X be denoted by y then angle Z=y (because isosceles angles of a traingle is equal)
Now,
y+y+24°=189°
2y+24°=180°
2y=180°-24°
y=156/2
y=78°
