angle CEB and AED are corresponding angles, so they are both are equal
since we already know that CEB is equal to 160, that means that AED is also equal to 160
all you have to do to find the value of x is subtract the 115 from 160, and so you get 45
so, x=45
hope this helps!! :)
Answer:
So whats the question then ????
Answer:
We conclude that the calibration point is set too high.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 1000 grams
Sample mean, = 1001.1 grams
Sample size, n = 50
Alpha, α = 0.05
Population standard deviation, σ = 2.8 grams
First, we design the null and the alternate hypothesis
We use One-tailed(right) z test to perform this hypothesis.
Formula:
Putting all the values, we have
Now,
Since,
We reject the null hypothesis and accept the alternate hypothesis. We accept the alternate hypothesis. We conclude that the calibration point is set too high.
Answer:
7-2x=22-3x
-2x=15-3x (minus 7 from both side)
x=15 ( plus 3x from both side)
I’m pretty sure the answer is 30!
