<h2>○=> <u>Correct option</u> :</h2>
<h3>○=> <u>Steps to derive correct option</u> :</h3>
Selling price of a car = $19,000
Percentage of sales tax in the city = 8.3%
Sales tax :
Thus, the sales tax on the car = $1577
Cost of license and title = $75
Total price of car :
= Cost price of car + Sales tax + cost of license/title
Thus, the total purchase price of the car = $20,652.00
Therefore, the correct option is <em>(C) $20,652.00</em>
Answer:
83.07
Step-by-step explanation:
If you multiple the original price $78 times the sale tax in decimal form 0.065 you get 5.07, $78 + $5.07 = 83.07.
The probability is 1/512
This is my work
So you know a die has 3 odd and 3 even so to get a even it is 1/2 chance now you have 9 die so you have to multiply 1/2 by itself 9 times so it can be represented by 1/2^9 (1/2 to the power of 9), which 1*1=1 so just look at the 2. 2^9 is 2*2*2*2*2*2*2*2*2 which is 512. So 1/512 chance they are all even.
Answer:
a) ρ (X,Y) = 0.125
b) The linear relationship is weak because ρ (X,Y) is almost 0
c) There is a positive linear relationship because ρ (X,Y) > 0
Step-by-step explanation:
The Pearson correlation coefficient is calculate as :
ρ (X,Y) = (σXY) / (σX)(σY)
-1 ≤ ρ ≤ 1
When ρ = 0 there is no linear relationship between the variables. This does not mean that the variables are independent.
When ρ = 1 the linear relationship is perfect positive. ρ = 1 means a direct relation between X and Y : When X increases also Y increases in constant proportion. When Y increases also X increases in constant proportion.
When ρ = -1 the linear relationship is perfect negative. ρ = -1 means a inverse relation between X and Y : When X increases Y decreases in constant proportion. When Y increases X decreases in constant proportion.
In our exercise ρ (X,Y) = 13.44 / (15.57)(6.90) = 0.125
a) ρ (X,Y) = 0.125
b) The linear relationship is weak because ρ (X,Y) is almost 0
c) There is a positive linear relationship because ρ (X,Y) > 0
Well. To put it simple, let's start off with an equation to help figure out this problem:
16/8 = ? / 2.55
(16 ounces are in a pound btw)
8 x 2 = 16
2.55 x 2 = 5.1
meaning:
16/8 = 5.1/2.55
Answer: 5.1 ounces of barley can be purchased with $2.55
Hope this helped! :D
