Answer:
y = x +9
Step-by-step explanation:
Side RS of triangle QRS is the one that is parallel to side UV. Being parallel, it has the same slope as UV. We observe that UV has a "rise" of 3 units (from 2 to 5) and a "run" of 3 units (from 1 to 4). Its slope is ...
m = rise/run = 3/3 = 1
__
The point-slope form of the equation for a line is ...
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
We observe that point S has coordinates (-8, 1), so we can write the equation of line RS in point-slope form as ...
y -1 = 1(x -(-8))
Adding 1 to both sides and simplifying, we have the slope-intercept equation ...
y = x +9
(?) is (-1) and that gray blank thing is 3.

Answer:
a) The confidence interval is
.
Step-by-step explanation:
We have to calculate a confidence interval (CI) of a difference of proportions.
For the existing procedure, the proportion is:

For the new procedure, the proportion is:

To calculate the CI, we need to estimate the standard deviation

For a 90% CI, the z-value is 1.64.
Then, the CI is:

Answer:
C
Step-by-step explanation:
The answer is C both the cube and rectangular prisms have 12 edges. We can tell the first two are wrong because both have 6 sides. We can tell the last one is wrong by counting. Both shapes have over 6 edges.
