Answer:
y=1/5x-24/5
Step-by-step explanation:
y-(-5)=1/5(x-(-1))
y+5=1/5x+1/5
-5 -5
y=1/5x+1/5-5
y=1/5x+1/5-25/5
y=1/5x-24/5
Answer:
The probability that the mean delivery time from the sample of 25 orders xˉ is farther than 2 minutes from the population mean cannot be calculated.
Step-by-step explanation:
As given in the question statement, the distribution of delivery times is strongly skewed to the right. The population distribution is skewed to right. Too much skewed distribution can cause the statistical model to work ineffectively and affects its performance. The probability can also not be calculated because the sample size is too small. Small sample size affects the results and makes them less reliable because it results in a higher variability and likelihood of skewing the results.
Answer:
A, C, D, H*, K
Step-by-step explanation:
<u>Given</u>:
y ≤ -2x +10
y > x -2
<u>Find</u>:
Points on the graph that satisfy the system of inequalities.
<u>Solution</u>:
In the attachment, we have plotted the boundary lines on the graph and indicated the half-plane that is part of the solution set. The points that satisfy both inequalities are ...
A, C, D, H*, K
______
Since the relations are written in slope-intercept form, it is convenient to plot the lines starting with the y-intercept, and working from there using the "rise"/"run" of the slope. The first inequality has a slope of -2, so the line falls two grid spaces for each one it goes to the right. y-values are less than or equal to those on the line, so shading is below the line.
The second inequality has a slope of +1, so the line rises 1 grid space for each one i goes to the right. y-values are greater than those on the line, so shading is above the line.
The points in the solution space are those to the left of the crossing point of the lines.
_____
<em>* Comment on the question</em>
The inequalities used in this answer were not supplied with this question, but were part of comments added to the question. The second inequality in your previous post was y > 1/2x -2. The shallower slope of that boundary line will exclude point H from the solution set. (H is on the boundary line, which is not part of the solution.)
Cost per ounce means you take the cost and divide it by the cost:
