No. 6r is 6 multiplied by r so in order to get r, you will need to divide both sides by 6 in the first equation so r should =12
Linear inequalities with two variables have infinitely many ordered pair solutions, which can be graphed by shading in the appropriate half of a rectangular coordinate plane. To graph the solution set of an inequality with two variables, first graph the boundary with a dashed or solid line depending on the inequality.
1) Linear model
R(t) = y = at + b
Where t is the year - 2000 (year since 2000)
For year 2006, t = 6; for year 2010, t = 10
Then:
1) 10.7 = a*6 + b
2) 34.2 = a*10 + b
Subtract (1) from (2)
34.2 - 10.7 = 10a -6a
23.5 = 4a
a = 23.5/4 = 5.875
Now from (1) 10.7 = 6a + b => b = 10.7 - 6a = 10.7 - 6*5.875 = - 24.55
Then the resulting model is R(t) = 5.875a - 24.55
2) Exponential model
R(t) = A[B]^t
(1) 10.7 = A[B]^6
(2) 34.2 = A[B]^10
Divide (2) by (1)
[34.2/10.7] = [B]^10 / [B]^6
3.1963 = [B]^4 => B = 1.3371
Now, from (1) 10.7 = A [1.3371]^6 => A = 10.7 / [1.337]^6 = 1.8725
Then, the model is R(t) = 1.8725{1.3371]^t
"on sale for 12% off" means that whatever the price is (y) we multiply it by 0.88 since 1-0.12 = 0.88
Price before discount = original price = y
Price after discount = 0.88y
Put another way, we took 88% of the original price to get the discount price.
------------------------------------
Now tack on the sales tax. We do this by multiplying the discount price by 1.03 (1 + 0.03 = 1.03)
So we have:
final cost = 1.03*(discount price)
final cost = 1.03*(0.88y)
final cost = 0.9064y
telling us that the final cost is 90.64% of the original price (y). With the tax added, the discount is not 12% but actually 100% - 90.64% = 9.36%
The correct statements about the box plots are:
the median of nadia’s data is equal to the median of ben’s data.
nadia had the highest score on a test.
<h3>Which statements are true?</h3>
A box plot is used to study the distribution and level of a set of scores. The scores are distributed into 4 groups. Each group has a value of 25%
The ends of the whiskers represents the minimum score and the maximum score. The maximum score of Nadia is 99 while that of Ben is 98.
The median is the line at the center of the box. Both lines are on the same number.
