Answer: x=10 7/8

Step-by-step explanation:

Subtract 3/4 from both sides. Multiply both sides by 3. Divide both sides by 2 (basically just isolate x on one side of the equal sign).

Minute Maid states that a bottle of juice contains 473 mL. Consumer groups are interested in determining if the bottles contain

kramer

Answer:

The average contents of all bottles of juice in the population

$\mu = 473\text{ mL}$

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 473 mL

Sample mean, $\bar{x}$ = 472 mL

Sample size, n = 30

Sample standard deviation, s = 0.2

First, we design the null and the alternate hypothesis

$H_{0}: \mu = 473\text{ mL}\\H_A: \mu < 473\text{ mL}$

Representation of $\mu$

It is the population parameter for mean.
Thus, it represents the average contents of all bottles of juice in the population, which is 473 mL.

Please help In the sequence below the first term is 2 and each term after the first is k times the preceding term where k is a c

Maslowich

Apparently k=6. It doesn't say it in the question, but I'll assume that you had a mistype and forgot to say that the second term is 12.
Anyway,
The nth term of a geometric sequence is $a_{1}* k^{n-1}$ . Thus, the 52nd term would be $2* k^{51}$ and the 50th term would be $2* k^{49}$ When you divide the two, the 2's would cancel out and k^49 would cancel out, leaving you with 1 on the bottom and k^2 on the top. As we said at the beginning, k=6, so our answer is just 6*6=36.

Line A has a slope of 6/10 and a line B has a slope of 3/5 are both lines parallel?

White raven [17]

Answer: Yes

Step-by-step explanation:

6/10 simplifies to 3/5, meaning they are proportionate. This means that the slope will be exactly the same and the lines will never intersect, meaning they are paralell.
