Answer:
k=2
Step-by-step explanation:
We have got a right triangle LNO with sides = m,4 and 8
By Pythagorean theorem
m^2=4^2 +8^2
Or m^2 = 80 ... i
IN triangle NOM, 4^2 +k^2 = l^2
i.e. 16+k^2 = l^2... i
In triangle LNM, m^2+l^2 = (8+k)^2
Substitute for m^2 as 80,
i.e. 80+l^2 = 64+k^2 +16k ... iii
From i, l^2 = 16+k^2
Substitute in iii
80+16+k^2 = 64+k^2 +16k
16k = 32 or k =2

Step-by-step explanation:
I took the test
Answer:
The sample size must be approximately 211.
Step-by-step explanation:
We are given the following in the question:
Sample mean, = 654.1
Alpha, α = 0.02
Population standard deviation, σ = 311.7
Margin of error = 50
Formula:
Putting all the values, we get,
Thus, the sample size must be approximately 211.
