Answer:
Step-by-step explanation:
take x degree as reference angle
using tan rule
tan x=opposite/adjacent
tan x=45/35
tan x=1.285
x=1.285
x=52.10 degree
x=52.1 degree

Answer:
y=-11
Step-by-step explanation:
A line can be represented by a linear equation of
where m is the slope and y is the y intercept.
The slope is 0 so this function will be
Which is also called a constant function. The y intercept is -11. So the answer is
Answer:
The proportion of student heights that are between 94.5 and 115.5 is 86.64%
Step-by-step explanation:
We have a mean and a standard deviation
. For a value x we compute the z-score as
, so, for x = 94.5 the z-score is (94.5-105)/7 = -1.5, and for x = 115.5 the z-score is (115.5-105)/7 = 1.5. We are looking for P(-1.5 < z < 1.5) = P(z < 1.5) - P(z < -1.5) = 0.9332 - 0.0668 = 0.8664. Therefore, the proportion of student heights that are between 94.5 and 115.5 is 86.64%
