The director of a hospital wishes to estimate the mean number of people who are admitted to the emergency room during a 24-hour period.
The director randomly selects 36 different 24-hour periods and determines the
number of admissions for each.
For this sample, x = 15.8 and s2 = 9
Estimate the mean number of admissions per 24-hour period with a 98% confidence
interval.
O 15.8 + 1.165
O 15.8 + 3.495
O 15.8 + 1.94
O 15.8 + .490

d

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.

answer is x<

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2

to complete this square you have to rotate about the origin 270 degrees clockwise.
