Answer:
Hope it helps!
Step-by-step explanation:
Sub y=5x into y=2x+3
so
5x=2x+3
3x=3
x=1
plug x=1 into y=5x
y=5
Checking work
Plug (1,5) into y=2x+3
5=2(1)+3
5=5
Plug (1,5) into y=5x
5=5(1)
5=5
Answer:
3 1/6
Step-by-step explanation:
To find the highest value, we have to evaluate each term individually,
1) 1 1/6 = 7/6 = 1.167
2) 3 1/6 = 19/6 = 3.16
3) 3/8 = 0.375
4) 5/8 = 0.625
Therefore, second data value (3 1/6) is highest.
Answer:
154.94 cm so pick the third answer.
Step-by-step explanation:
5*12+1=61 total inches.
61*2.54=154.94 cm
<span>To convert a percentage to a decimal you move the decimal two places to the left. Therefore:
15.% becomes .15
You then multiply this decimal to the number you are trying to find the percentage of.
.15 × 60 = 9.
9 is 15% of 60.

Answer: (A) H0: μ = 140 mg vs. H1: μ ≠ 140 mg
Step-by-step explanation:
Usually null hypothesis represents the claim that the values associated to the groups being tested have no statistical difference but alternative hypothesis supports the claim that there is statistical difference.
Let
be the population mean .
We are given that the mean potassium content of a popular sports drink is listed as 140 mg in a 32-oz bottle.
i.e. Null hypothesis :![H_0:\mu=140](https://tex.z-dn.net/?f=H_0%3A%5Cmu%3D140)
Alternative hypothesis for two tail hypothesis has sign (≠).
i.e. Alternative hypothesis : ![H_1 : \mu\neq140](https://tex.z-dn.net/?f=H_1%20%3A%20%5Cmu%5Cneq140)
∴ The hypotheses for a two-tailed test of the claimed potassium content:
H0: μ = 140 mg vs. H1: μ ≠ 140 mg
