Answer:
Although i am not sure, I believe the answer is 56.
Step-by-step explanation:
A right angle is 90 degrees.
90 - 28 = 62
by the looks of it, the angle on to of the place of the 62 looks identical, so i will assume it is also 62 degrees.
62 + 62 = 124
180 - 124 = 56
So that is why I believe it is 56.
(I may either be completly right or completely wrong. If it has answer choices, look at them and see if it is an option)
Hope it helped anyways!
Aaaa i don’t think you picture matches the equation!
It’s the 4th option
<—> this sign thingie represents the interchanging sign like x=y y=x
A. -1
(1,2) and (2,1)
slope = 2 -1 / 1 -2
slope = 1 / -1
slope = -1
Answer:
[143.61, 156.39]
Step-by-step explanation:
Because the population standard deviation is not available AND the sample size is less than 31, we can use a t procedure here.
Plug these values into your calculator:
Sample mean = 150
Sample size = 16
Standard deviation = 12
Confidence level = 95% = 0.95
and get [143.61, 156.39] as your confidence interval
