Answer:
- 10 and 60
Step-by-step explanation:
1
To evaluate f(- 2) substitute x = - 2 into f(x)
f(- 2) = (3 × - 2) - 4 = - 6 - 4 = - 10
2
To evaluate f(8) substitute x = 8 into f(x)
f(8) = 8² - 4 = 64 - 4 = 60
Answer:
Option A) 2.5
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 46
Sample mean, = 50
Sample size, n = 25
Alpha, α = 0.05
Population standard deviation, σ = 8
First, we design the null and the alternate hypothesis
Formula:
Putting all the values, we have
Option A) 2.5
Since it's multiplication we can Multiply the constants. In this case 4, 15, and 2. We get 120. We now then multiply the variables. We then get the answe 120mnx
2 * (2*3.14*R) =
2 * (2*3.14*70) = 879,2
so the answer is about 879,2 meters
