Answer:
$1890
Step-by-step explanation:
x= couches
y=chair.
x=2y
2x=3y+270
2(2y) or 4y=3y+270
y=270
x=540
2(540)+3(270)=1890.
Hope this helps :D

Answer:
A. The first equation is for sample data; the second equation is for a population.
Step-by-step explanation:
The first equation is y = 
, this is the equation for sample data as the intercept (
) and the slope parameter(
) both are calculated then we have got this and these values are not taken as given.
The Second equation is 
, this is the equation for population data as we can't calculate these 
and 
as we take these values as given and also we do testing for 
parameter using t test and it is sure that testing is always done on population data not on sample data.
We are going to have to divide...
We have to put 1 as a denominator for 3 because it's a whole.
Cross multiply.
Each person would get
of the original pizza.
Have a nice day! :)
Answer:the selling price if payment is made in cash is $395
Step-by-step explanation:
The list price of the computer software program is $500
A dealer offers the computer software program at a 19% discount.
She will give an extra 3% discount if paid in cash. This means that the total discount in percentage if a customer paid in cash would be
19 + 3 = 21%
The value of the discount would be
21/100 × 500 = 0.21 × 500 = $105
Therefore, the selling price if payment is made in cash would be
500 - 105 = $395
