Answer:
C. y = 5x
Explanation:
(5 - 15) / (1 - 3)
-10 / -2
5
Answer:
about 76.2°
Step-by-step explanation:
The geometry can be modeled by a right triangle with the given dimensions being the side opposite the angle (height = 33,500 ft) and the side adjacent to the angle (8,200 ft). The fact that you know these two sides suggests the inverse of the tangent function may be useful.
Tan = Opposite/Adjacent
tan(angle) = (33,500/8,200)
angle = arctan (335/82) ≈ 76.246°
The angle of elevation is about 76.2°.
42 - -84=-42
Hope this helps :)
Answer:
We are given:
Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed.
Since the alternative hypothesis has less than sign, therefore the given hypothesis is left-tailed
What parameter is being tested?
The parameter used is 
, which denotes the population mean.
Please note:
The type is test determined based on the alternative hypothesis.
If the alternative hypothesis has 
sign, it means the hypothesis test is two-tailed
If the alternative hypothesis has 
sign, it means the hypothesis test is right-tailed
If the alternative hypothesis has 
sign, it means the hypothesis test is left-tailed
