Is 7n - 8m = 4-2m a linear equation? If so, put it in standard form.

Alex777 [14]

Answer:

1.a. E>D

b. E<F

2. Yes. There are multiple combinations on how to do number 1. The first question asks how for a, you need a letter that is bigger than another letter, and for b, you need a letter that is smaller than the other letter's value. There are many ways to go about that previous problem.

Step-by-step explanation:

Hello!

To solve this question, we first need to realize that this is a simple number line. A number line is just a line that contains multiple points from the left being negative, middle is zero, and right becoming increasingly positive.

In this case, D is zero, and A-C are deemed negative. E-F are positive.

For a, we need to find a point that is bigger than another point.

We have various answers for this. F is bigger than A-E, E is bigger than A-D, D is bigger than A-C, C is bigger than A-B, and B is bigger than A. As long as any of your answer goes along this format it is correct.

B is asking a number that is smaller than that said number. A is smaller to B-F, B is smaller to C-F, C is smaller to D-F, E is smaller to F. So again, any letter combination that falls within this category is correct.

For the last one, there are multiple combinations, meaning there is just not one answer that fulfills that question.

13+(w)/(7)=-18 step by step?

kotykmax [81]

w in (-oo:+oo)

w/7+13 = -18 // + 18

w/7+13+18 = 0

1/7*w+31 = 0 // - 31

1/7*w = -31 // : 1/7

w = -31/1/7

w = -217

An experimenter conducted a two-tailed hypothesis test on a set of data and obtained a p-value of 0.44. If the experimenter had

Lyrx [107]

Answer:

Correct option is (C).

The possible value of the p-value for a one-tailed test are 0.22 and 0.78.

Step-by-step explanation:

The p-value is the probability of acquiring a result as extreme as the observed result, assuming the null hypothesis statement is true.

The p value of a test is:

Left-tailed test: $P(TS$

Right-tailed test: $P(TS>ts) = 1- P(TS$ .

Here,

TS = Test statistic

ts = computed value of the test statistic.

The two-tailed p-value is: $2P(TS$ or $2P(TS>ts)$ .

The p-value of the two tailed test is, 0.44.

Compute the p-value for one-tailed test a follows:

For a left-tailed test:

$2P(TS$

For a right-tailed test:

$P(TS>ts) = 1- P(TS$

Thus, the possible value of the p-value for a one-tailed test are 0.22 and 0.78.

The correct option is (C).

2 pipes running together can fill a cistern in 3 1÷3 min.if one pipe takes 3 min more than the other to fill it,find the time in

charle [14.2K]

It takes one pipe x minutes, the other pipe x+3 minutes
the portion filled per minute is by one pipe is 1/x, by the second pipe 1/(x+3)

when two pipes running together:
3&1/3[1/x+1/(x+3)] =1, 1 means the whole cistern
solve for x: 3&1/3(x+3) +3 1/3(x)=x(x+3)
6 &2/3 x +10 =x^2+3x
x^2- (3&2/3) x-10=0
3x^2-11x-30=0

this cannot be factored, so use the quadratic equation:
x is about 5.5
x+3=8.5
