First, you convert 33 1/3 % into decimals which is 0.33333333333 then you multiply 29.99 by the decimal to get the amount you save which is then subtracted from the initial amount.
29.99 x 0.33 1/3 = 9.99667
29.99 - 9.99667 = 19.99
Hope this helps!
we have to choose the correct conic section to fit the equation.x ^2+ y^ 2= 9. we know the equation of a circle is x^2 + y^2 = r^2
and if we compare both the equations we find that both are similar and we can even find the value of r by comparing both the equations.
So the correct conic section is circle
Answer:
As both the mean and standard deviation are in the desired ranges, the tool passes the technical control.
Step-by-step explanation:
Mean of the batch:
The mean of the batch is the sum of all values divided by the number of items. So
Mean in the desired interval.
Standard deviation:
Square root of the sum of the difference squared between each term and the mean, divided by the number of items. So
As both the mean and standard deviation are in the desired ranges, the tool passes the technical control.
(4y-3)(2y²+3y-5)
First , let's start with "4y"
4y*2y² = 8y³
4y*3y = 12y²
4y*-5 = -20y
Next, let's multiply by "-3"
-3*2y² = -6y²
-3*3y = -9y
-3*-5 = 15
Now, let's combine all of our values.
8y³+12y²-6y²-20y-9y+15 = 8y³+6y²-29y+15
