There are two different music download companies that offer a monthly plan for downloading songs. S-Jams charges $1.29 per song plus $10 monthly fee. C-tunes charges $0.99 per song plus $16 monthly fee. When will the company’s plans cost the same? Write an expression for the cost of S-Jams.

Answers

Answer:

Thus, when both S-jams and C-tunes have 20 songs downloaded in a month , the cost will be same.

an expression for the cost of S-Jams $0.99n + $16

Step-by-step explanation:

For

S-Jams

cost of 1 song = $1.29

let there be n songs downloaded in a month

then

cost of n songs = n*cost of 1 song = $1.29n

monthly fee = $10

Total cost of S-Jams = $1.29n+$10

________________________________________

For

C-Tunes

cost of 1 song = $0.99

let there be n songs downloaded in a month

then

cost of n songs = n*cost of 1 song = $0.99n

monthly fee = $16

Total cost for C-Tunes= $0.99n + $16

we have to find When will the company’s plans cost the same.

Total cost of S-Jams = Total cost of C- Tunes

1.29n+10 = 0.99n + 16

=> 1.29n - 0.99n = 16-10

=> 0.30n = 6

=> n = 6/0.3 = 20

Thus, when both S-jams and C-tunes have 20 songs downloaded in a month , the cost will be same.

an expression for the cost of S-Jams $0.99n + $16

The two key parts of regression equation involve the______ and the y'________ a. slope; axis
b. asymptote; axis
c. asymptote; intercept
d. slope; intercept

Answers

Answer:

d. slope; intercept

Step-by-step explanation:

A regression equation is represented in the form :

y = mx + c (linear regression)

Where y = predicted variable

m = slope of regression line

x = independent variable

c = intercept (where the regression line crosses the y axis).

For a multiple regression equation where there are more than one independent, then we have multiple slopes

y = c + m1x1 + m2x2 +...mnxn

Hence, the slope. And intercept are the two key part of a regression equation which enables us to make prediction and correlation about the dependent and independent variables.

Answer:

y = 3x + 3

Step-by-step explanation:

y = mx + b

m = slope

m = y2-y1/x2-x1 = 9-6/2-1 = 3/1 = 3

m = 3

b = y-intercept

b = 3

Answer:

The answer would be y = 3x + 3.

Rewrite 3/11 amd 1/4 so they have a common denominator

Answers

Hello!

Answer:

$\Large \boxed{\sf (12)/(44) ~~ and~~ (11)/(44) }$

Step-by-step explanation:

We want that the fractions 3/11 and 1/4 have a common denominator.

Let's find the LCM (least common multiple) of 4 and 11:

$\text{\sf Multiples of 4:}~~ \sf 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, \boxed{\sf 44}, 48\n\n\text{\sf Multiples of 11:} ~~ \sf 11, 22, 33, \boxed{\sf 44}, 55, 66, 77, 88, 99, 110$
