Answer:
the answer for the operation that should be used to solve x+7 is -7
All the angles make a full circle which needs to equal 360 degrees.
Add all the angles together to equal 360:
X + (x-10) + (4x-20) +(2x-10) + (x +10) = 360
Combine like terms:
9x -30 = 360
Add 30 to both sides:
9x = 390
Divide both sides by 9:
X = 390/9
X = 43.3333. ( 43 and 1/3)
Answer:
Option B) Fail to reject the null hypothesis that the true population mean annual salary of full-time college professors in the region is equal to $127,000.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = $127,000
Sample mean, = $126,092
Sample size, n = 160
Alpha, α = 0.10
Sample standard deviation, σ = $8,509
First, we design the null and the alternate hypothesis
We use Two-tailed t test to perform this hypothesis.
Formula:
Now,
Since,
The calculated t-statistic lies in the acceptance region, we fail to reject and accept the null hypothesis.
Option B) Fail to reject the null hypothesis that the true population mean annual salary of full-time college professors in the region is equal to $127,000.
The slope-intercept form of the graph is .
Solution:
Let us take any point on the straight line.
Here, we take (–8, 0) and (0, 4).
Let us first find the slope of the line.
Slope of the line formula:
Slope-intercept form:
Hence the slope-intercept form of the graph is .

Answer:
354,998
Step-by-step explanation:
If the number is less than 350,000, it will not round to 400,000.
If the number is 355,000 or more, it will not round to 350,000.
The number (n) must satisfy ...
350,000 ≤ n < 355,000
__
If we're restricted to integers, the number could be any between 350,000 and 354,999, inclusive. One possibility is 354,998.
