Answer:
The answer is F) none of the above. The correct sales tax is $902.72
Step-by-step explanation:
35×.2= 7 dollars is being taken away from the sale.
35-7= 28 dollars which is the new cost.
28×.06=1.68
28+1.68=29.68 final cost of jeans
or you can do 28×1.06= 29.68 final cost of jeans.
Dt = 2(0.8)t = 1.6t = 1.6(10) - 1.6(5) = <span>8 m/s</span>
Answer:
C. Must be 1
Step-by-step explanation:
The correlation coefficient of an equation represents the relation between the two variable ( dependent and independent )
It lies between -1 to 1,
If an equation has strongly positive correlation then the value of correlation coefficient is 1,
If there is no relation then the value of correlation is 0,
If there is strongly negative relation then the value of correlation coefficient is -1,
Here, the equation is,
y = 2 + 3x
Since, the value of y is increasing with increasing the value of x,
We can say that there is strong positive relation between the variables x and y,
Hence, by the above statements,
The correlation coefficient between y and x in this data set must be 1.
Option 'C' is correct.
j=4.88 when g=8 and v=11
Further explanation:
When the increase/decrease in one quantity cause increase/decrease in other quantity, it is called direct variation.
Variation is always accompanied by a variation constant.
<u>Given</u>
g and v vary directly with j
IT can be written as:
j∝gv
Putting the variation constant k
j = kgv
Putting g = 6 and v=3
So the value of k is 1/18 which makes the equation
So, j=4.88 when g=8 and v=11
