Area of a square = (length of a side)²
64 = x²
√64 = x
8 = x
So the length of a side is 8

(Q) Find the amount in the account at the end of 2 years.
(A) $16,380
Answer:
1.5p + 3p + 2.5p
Step-by-step explanation:
This expression, 1.5p + 3p + 2.5p, will represent the amount of money received when p people buy one of each food item.
Since the price of each is the coefficient for p, this will represent how much money will be gained from each food item. All 3 terms will be added together to represent the total amount of money gained from selling all 3 items.
Answer:
If y=2x+7 were changed to y=5x+7, then the graph of the new function would be steeper than the graph of the original function. On the other hand, the y-intercept would be unchanged; ( 0, 7)
Step-by-step explanation:
If y=2x+7 were changed to y=5x+7, then the graph of the new function would be steeper than the graph of the original function. On the other hand, the y-intercept would be unchanged; ( 0, 7)
Answer:
(a) is true
Step-by-step explanation:
Given
See attachment for box plots
Required
Which of the options is true?
Option A compares the IQR of both plots.
IQR is calculated using:
![IQR = Q_3 - Q_1](https://tex.z-dn.net/?f=IQR%20%3D%20Q_3%20-%20Q_1)
Where
Lower quartile
Upper quartile
From the attached plots, we have:
Republican
![Q_1 = 170.5](https://tex.z-dn.net/?f=Q_1%20%3D%20170.5)
![Q_3 = 356](https://tex.z-dn.net/?f=Q_3%20%3D%20356)
So:
![IQR = 356 - 170.5](https://tex.z-dn.net/?f=IQR%20%3D%20356%20-%20170.5)
![IQR = 185.5](https://tex.z-dn.net/?f=IQR%20%3D%20185.5)
Democratic
![Q_1 = 181](https://tex.z-dn.net/?f=Q_1%20%3D%20181)
![Q_3 = 367.5](https://tex.z-dn.net/?f=Q_3%20%3D%20367.5)
So:
![IQR = 367.5 - 181](https://tex.z-dn.net/?f=IQR%20%3D%20367.5%20-%20181)
![IQR = 186.5](https://tex.z-dn.net/?f=IQR%20%3D%20186.5)
We have:
--- Republican
--- Democratic
<em>Hence, (a) is true</em>
