Answer:
See the attachment for the appropriate choice.
Step-by-step explanation:
Both equations are in slope-intercept form. Both have a y-intercept of -2, so only a graph where the lines cross at (x, y) = (0, -2) is a viable choice.
In both cases, the inequality requires that values of y be "less than (or equal to)" those described by the line. Hence, the shading will be below both lines.
Answer:
Step-by-step explanation:
The larger the sample size, the lower the standard deviation. The standard deviation shows how the data is spread from the mean. Therefore, benefit of increasing the sample size when trying to estimate the mean from a sample average are
a. A reduction in the bias of the estimate.
b. A reduction in the variability of the estimate.
The width of confidence interval is determined by the margin of error
Margin of error = z × s/√n
A smaller standard deviation and increased size would result to a narrower confidence interval. Therefore, increasing the sample size does not result to an increase in the width of the resulting confidence interval.
Answer:
Slope= -2
y-intercept= -4
Step-by-step explanation:
To find the slope and y-intercept of a given equation, first rearrange the equation such that it is in the slope-intercept form. In the slope-intercept form, the coefficient of y is 1 and the rest are moved to the left hand side of the equation.
- y= mx +c, where m is the slope and c is the y-intercept
Given equation: 6x +3y= -12
Let's leave the y term on the left of the equation and bring the rest to the right.
3y= -6x -12
To ensure that the coefficient of y is 1, divide both sides by 3.
y= -2x -4
The equation is now in the slope-intercept form.
The slope is the coefficient of x (the number that comes before x), thus the slope is -2. The y-intercept is -4.
Answer:
7x - 5 7x - 5
(f/g) = ----------------- = ----------------
2x - 4 2(x - 2)
Step-by-step explanation:
Given f(x) = 7x-5 and g(x)=2x-4, we form the quotient f/g as follows:
7x - 5 7x - 5
(f/g) = ----------------- = ----------------
2x - 4 2(x - 2)
Note that this is not defined for x - 2, due to division by zero.
Answer:
5: yes he could easily chose bigger looking families to get the result he wants
6: no he has isn't choosing people and has no idea the answers presumibly
7: no it's not something that they could choose or know what is going to happen, therefore or can't be biased.
I'm not sure if I did it right but I think that's what it's asking sorry if I'm wrong
