Answer:
it will not change
Step-by-step explanation:
the outlier is 3
the mode is the most occuring value in the list which is 16 before and after the 3 is removed
Area of triangle = I/2*b*h
96 = I/2*b*8
96 = 4b
24in = b
Therefore perimeter = 24*3
= 72in
The length of B'C' in the rectangle A'B'C'D' = 9 units.
<u>Step-by-step explanation</u>:
step 1 :
Draw a rectangle with vertices ABCD in clockwise direction.
where, AB and DC are width of the rectangle ABCD.
AD and BC are length of the rectangle ABCD.
step 2 :
Now,
The length of the rectangle is AD = 5 units and
The width of the rectangle is AB = 3 units.
step 3 :
Draw another rectangle with vertices A'B'C'D' extended from vertices of the previous rectangle ABCD.
step 3 :
The length of the new rectangle is A'D' which is 4 units down from AD.
∴ The length of A'D' = length of AD + 4 units = 5+4 = 9 units
step 4 :
Since B'C' is also the length of the rectangle A'B'C'D', then the measure of B'C' is 9 units.
Ok so the total amount the mom paid is 50.50. It says she bought 10 journals at 2.50 each so subtract 25 which leaves 25.50. Then it says 2 markers at 5 each so subtract 10 which leaves 15.50. Then it states she paid 4.10 in annoying sales tax. So subtract 4.10 and you get 11.40 which is the remaining, which means thatbis how much she spent on a mouse.
x – 2y = 4
ax– 6y = 12
The second equation must has a value for a that makes the second equation equal to the first. In other words a has to be something that divides through the second equation to get the first.
The easiest way to proceed is to look at the right hand side. One equation has 12 on the right. The other has 4. What do you have to do to 12 to get it down to 4. I suppose you could subtract 8, but that would not apply to the left side.
The answer is divide 12 by 3.
If you do that then the 6 is divided by 3.
Find a
Now you need to consider a's value. It is either 1 or 3. If you choose 1, you will not be able to divide properly: dividing by 3 will leave you with 1/3.
The thing you must do is make a = 3
The second equation then becomes
3x - 6y = 12 Divide everything by 3
x - 2y = 12/3 = 4
Answer: a = 3
