Answer:
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 108
Sample mean,
= 107
Sample size, n = 110
Alpha, α = 0.02
Population standard deviation, σ = 7
Formula:
Putting all the values, we have

The test statistic is -1.50
A third are spotted so that would mean 2/3 are not spotted so if you take 1200 divide it by 3 and then multiply it by 2 you get 800 which is your answer
Answer:
130 degrees
Step-by-step explanation:
Since angles P and Q are supplementary (meaning that they add up to 180), we can set up the equation:
180 = 50 + Q
Q = 130
Answer:
Tangent = opposite / adjacent
Tangent of 45º equals 1
Step-by-step explanation:
5x + 50 +x
= 5x*2( square ) + 50
