190 = 6n - 2(-8n - 7)
andrew11 [14]

Answer:

n=8

  • First you remove the parentheses making it 190=6n+16n+14
  • Then you combine like terms making it 190=22n+14
  • After that, you move the terms making it -22n=14-190
  • After that, you calculate and that gives you -22n=-176
  • Lastly, you divide both sides leaving you with n=8

At a high school debate tournament, half of the teams were asked to wear suits and ties and the rest were asked to wear jeans an
vovangra [49]

Answer:

A) The proportions of wins is the same for teams wearing suits as for teams wearing jeans

Step-by-step explanation:

Although the question says that they will "test the claim at the 0.05 level that the proportion of win is the same for teams wearing sutis as for the teams wearing the jeans", the claim, that will be expressed in the alternative hypothesis, is that there is a significant difference between the two proportions.

The null hypothesis, the one that this test try to nullify, will state that there is no significant difference between the two proportions. Or, saying the same, that the proportions are equal.

The right answer is A, which states that the two proportions (as this is a test on the difference of proportions) are equal.

The royal fruit company produces two types of fruit drinks the first type is 70% pure fruit juice and the second type is 95% pur
Ipatiy [6.2K]
This is a typical mixture problem where using a table is the best thing.
                 pints juice        % juice     =      total % juice
juice A            x                  .70          =        .70x
juice B        60-x                 .95          =    .95(60-x)
total              60                  .75          =    60(.75)

The last row gives you a total that you need to use, so do that multiplication to get 45. You now to need to add the last columns together for rows 1 and 2 and set them equal to 45: .7x +.95(60-x) = 45. When you do that math, you'll get that x = 48. This means that you need 48 pints of juice A and 60-48 pints of juice B, which is 12 pints.
