2+7x=4-3x I need help solving

Answers

Answer 1

Answer: X=1 for the first equation for the second X=9 Because 2+7=9*1=9 then you do 4-3=1*9. GOOD LUCK!(:

Answer 2

Answer:    2 + 7x = 4 - 3x
      + 3x + 3x
   2 + 10x = 4
- 2    - 2
   10x = 2
      10 10
   x = 0.2

Weston completed a hypothesis test and found that he could not reject the null hypothesis. Which of the following is a valid reason for his conclusion? A.The z-statistic is less than 0.
B.The z-statistic lies in the critical region.
C.The z-statistic is greater than 0.
D.The z-statistic lies outside the critical region.

Answers

Answer: D.The z-statistic lies outside the critical region.

Step-by-step explanation:

When we run a hypothesis test , the result of that test will be a probability value. The probability value is represented by a “p value” .

It tells us if hypothesis statement is probably true or not.

If the value falls in the rejection region, it means you have statistically significant results; You can reject the null hypothesis.

If the p-value falls outside the rejection region, it means your results aren’t enough to throw out the null hypothesis.

Hence, if Weston ound that he could not reject the null hypothesis. The z-statistic lies outside the critical region would be the valid reason for his conclusion.

The right answer for the question that is being asked and shown above is that: "D.The z-statistic lies outside the critical region." Weston completed a hypothesis test and found that he could not reject the null hypothesis. A valid reason for his conclusion is that D.The z-statistic lies outside the critical region.

The question that I'm having issues with is, "The complement of an angle, A, in degrees, is equal to one-sixth of the supplement of the angle, also in degrees. Then A= "I know the answer is 72 degrees, but I don't know how to figure the problem out!

Answers

'Complement' = difference between an angle an 90 degrees.

'Supplement' = difference between an angle and 180 degrees.

Complement of A = 90 - A

Supplement of A = 180 - A

The problem says that the complement is 1/6 of the supplement, right ?

So 90 - A = (1/6) x (180 - A)

Multiply each side of this equation by 6 :

540 - 6 A = 180 - A

Subtract 180 from each side:

360 - 6 A = - A

Add 6A to each side :

360 = 5 A

Divide each side by 5 :

A = 72°

$90-A=(180-A)/(6)\n 540-6A=180-A\n 5A=360\n A=72$
