Answer:
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 206 mg
Sample mean,
= 217.5 mg
Sample size, n = 14
Sample standard deviation, s = 14.9 mg
Claim:
The mean sodium content for the sports drink is not 206 mg. It is different than 206 mg.
Thus, we design the null and the alternate hypothesis
We use two-tailed t test to perform this hypothesis.
Answer:
m<R = 22.62°
Step-by-step explanation:
Reference angle = R
Opposite = 5 cm
Hypotenuse = 13 cm
Apply the trigonometric function SOH:
Sin R = Opp/Hyp
![Sin (R) = \frac{5}{13}](https://tex.z-dn.net/?f=%20Sin%20%28R%29%20%3D%20%5Cfrac%7B5%7D%7B13%7D%20)
![R = sin^{-1}(\frac{5}{13})](https://tex.z-dn.net/?f=%20R%20%3D%20sin%5E%7B-1%7D%28%5Cfrac%7B5%7D%7B13%7D%29%20)
R = 22.6198649°
m<R = 22.62° (nearest hundredth)
Answer:
base=5
height=3
Step-by-step explanation:
Answer:
Below.
Step-by-step explanation:
The correct answer is D. Average daily balance method.
Train traveled 175 kilometers (86+89) in 7 hours (2+5).
speed = distance/time
speed = 175 / 7
speed = 25 kilometers / hour
