fgiga [73]2 years ago
7 0

Answer:

  • 7m minutes

Step-by-step explanation:

<u>We know that:</u>

  • 3 days of practice = Monday + Tuesday + Wednesday
  • Monday = m
  • Tuesday = m + 6
  • Wednesday = 5m - 6

<u>Solution:</u>

  • 3 days of practice = Monday + Tuesday + Wednesday
  • => 3 days of practice = m + m + 6 + 5m - 6

[Simplifying]

  • => 3 days of practice = 7m - 6 + 6

[Final Answer]

  • => 3 days of practice = 7m

Hence, the total number of minutes she practiced over the course of the three days is 7m minutes.

Serggg [28]

Answer:

The claim that less than 50% of internet users get their health questions answered online is correct, given that according to the survey, 45.98% of people do.

Step-by-step explanation:

Since an online health and medicine company claims that about 50% of Internet users would go to an online sight first for information regarding health and medicine, and a random sample of 1318 Internet users was asked where they will go for information the next time they need information about health or medicine; 606 said that they would use the Internet, to test the claim that less than 50% of Internet users get their health questions answered online, the following calculation must be performed:

1318 = 100

606 = X

606 x 100/1318 = X

60600/1318 = X

45.978 = X

Therefore, the claim that less than 50% of internet users get their health questions answered online is correct, given that according to the survey, 45.98% of people do.

Find the Slope and Y- intercept of the line
lara [203]
Find slope by calculating rise over run (can pick whatever points are easiest for you). I'm choosing (0,2) and (-3,0)

(0-2)/(-3-0)
(-2)/(-3)
2/3

Slope=2/3

Y intercept is the value of y when x is 0. We can look to see the y intercept is 2.

Final answer: D
