The n two number are n and n+7. The two numbers are relatively prime because 7 is prime and doesn't divide 60. So we get n(n+7)=60. Guess and check tells us the two numbers are 5 and 12.

The data show the number of viewers for television stars with certain salaries. Find the regression​ equation, letting salary be
larisa86 [58]

Answer:

y = 5.064 - 0.010x

Here, in this question x = 33

y = 4.734 million views

In this question data is missing and I filled it out and calculated the questions accordingly. Please refer to the attachment for the data calculated.

Step-by-step explanation:

First of all, this question is incomplete. It lacks the data needed to calculate the required things.

So, I  figured out the question and I will try my best to solve the question at hand.

I have calculated the some data sheet in excel. Please refer to the attachment for that data.

let a be the salaries

b be the viewers

S_{aa} = ∑a^{2}  - \frac{ Summtion  a^{2} }{n}

S_{aa} = 7522.8571

S_{bb} = ∑b^{2}  - \frac{ Summtion  b^{2} }{n}

S_{bb} = 47.1943

S_{ab} = ∑ab^{}  - \frac{ Summtion  a x Summation b^{} }{n}

S_{ab} = -76.8286

Now the slope of the required regression equation is:

Slope =  S_{ab}/S_{aa} = -76.8286/7522.8571 = -0.010

And the intercept of the required regression equation:

intercept = \frac{1}{n} x (∑b - slope x ∑a) = 5.064

So, the regression equation will be:

y = intercept + slope x

y = 5.064 - 0.010x

Here, in this question x = 33

y = 5.064 - 0.010 (33)

y = 4.734 million views

Mrs. Cho has 24 students in her class. Some of her students are also in the play. Explain why it is not possible for exactly 24%
lora16 [44]
Let's start by calculating how many students does 24% represent.
24% * 24 = 0.24 * 24 = 5.76
We got a decimal number as solution. The reason why exactly 24% students can't be in the play is because this percentage does not represent whole number of students. She can't take 0.76 students

If she wanted 25% students to be in a play it would mean she has to take:
25% * 24 = 0.25 *24 = 6 students
