       4x + 5y = -15
4x - 4x + 5y = -15 - 4x
               5y = -4x - 15
                5          5
                 y = ⁻⁴/₅x - 3

27 divided by N has a remainder of 3.<br> How many different positive integers could n be?
myrzilka [38]

Solving this question will involve basic division knowledge.

<em><u>The different positive integer values of n are; 4,6,8,12,24</u></em>

From knowledge on division, we know that when 27 is divided by N and we have 3 as remainder, we can express it as;

\frac{27}{n} = quotient + \frac{3}{n}

Now let us rearrange to get;

\frac{27}{n} - \frac{3}{n} = quotient

this gives;

\frac{24}{n} = quotient

Now to get how many positive integers can be n, it means all positive values of the quotient must be positive integers as well.

Factors of 24 are; 1, 2, 3, 4, 6, 8, 12, 24

Thus, the possible positive integers will come from this list.

But we can't make use of 1,2,3 as possible values of n because when we divide with 27, we will get either an exact value or 1 as the remainder.

Thus <em>the possible positive integer values of n are; 4,6,8,12,24</em>

A cylinder has a volume of 825.192 cubic centimeters. The diameter of the cylinder is 12 cm. What is the height of the cylinder?
Reika [66]

Answer:

Step-by-step explanation:

diameter = 12 cm

r = 12 ÷2 = 6cm

Volume of cylinder

\boxed{Volume=\pi r^{2}h}

πr²h = 825.192 cubic cm

3.14 * 6 * 6 * h = 825.192

                   h =\dfrac{825.192}{3.14*6*6}

                  h = 7.3 cm

Different hotels in a certain area are randomly​ selected, and their ratings and prices were obtained online. Using​ technology,
hoa [83]

Answer:

Step-by-step explanation:

Hello!

A linear regression for the price of renting a room in a hotel and the rating said hotel received was calculated from a sample of n= 25 hotels.

The theoretical regression model is E(Y)= α + βXi

And the estimated regression equation is: ^Y= a + bXi

Where:

The estimator for the slope is b= 125

And the estimator of the Y-intercept is a= -400

So for this example the estimated regression line for the price of the hotel rooms given the ratings of the hotel is:

^Y= -400 + 125 Xi

^Y= represents the estimated average price of a hotel room

a= -400 is the estimated average price of a hotel room when the rating of the hotel is zero.

b= 125 is the modification of the estimated average price of a hotel room when the rating of the hotel increases one unit.

I hope this helps!
