The pay rates of these two people are not proportional because if you divide 234 by 36 and 288 by 40, it is shown that Miguel earns $7.20 every hour and Jeremy earns $6.50 per hour. Thus, the pay rates of these two people are not proportional.

1.2million users of social media via mobile devices were added each day. How many users added on an average each second
Pachacha [2.7K]

Answer: 14 new users are added per second

Step-by-step explanation:

1,200,000/24 = 50000

50000/60 = 833.333333333

833.333333333/60 = 13.8888888889

then round because it said on average

so if we round 13.8888888889 we get 14

so on average 14 new users are added per second.

Please help as soon as possible
ch4aika [34]

To solve this problem you must apply the proccedure shown below:

You must switch the variables, and then, you must solve for y, as following:

x=-\frac{1}{2} \sqrt{y} +3\\ (x-3)^{2} = (\frac{1}{2}\sqrt{y})^{2}   \\ y=4x^{2} -24x+36\\ f^{-1}  (x)=4x^{2} -24x+36

Therefore, as you can see, the answer is: f^{-1} (x)= 4x^{2} -24x+36

(URGENT) Madelina wants to make a prediction using a linear model with a correlation coefficient of 0.55.
alekssr [168]

Answer:

<h2>Her prediction will be somewhat likely to be close to the actual value.</h2>

Step-by-step explanation:

A correlation coefficient of 0.55 implies a weak positive correlation, because it's close to 0.50. Remember that strong correlations are 1 or -1, positive or negative, and the middle of the interval represents no correlation.

Having said that, 0.55 indicates some correlation, but weak. Therefore, the right answer is C.
