P+A=420
P=6A
6A+A=420
7A=420
A=60
P=6(60)
P=360
CHECK:
P+A=420
360+60=420
420=420
Answer:
y = -3
Step-by-step explanation:
y + 3 = 7(2 - 2)
y + 3 = 0
Subtract 3 from both sides
y + 3 - 3 = 0 - 3
y = -3
In order to answer this question we have to find all the 4 measure, Mean, Median, Mode and Range of both data sets.
1) For the Rocks of Isabella:
Mean = (Sum of all numbers)/Total numbers
So, Mean weight of Isabella's Rocks = 7.64
Median is the central value.
So, Median weight of Isabella's Rocks = 6
Mode is the most frequently occurring value.
So, Mode weight of Isabella's Rocks = 8.75
Range = Maximum - Minimum
So, Range weight of Isabella's rocks = 13.75
2) For Mateo's Rocks:
Mean = 8
Median = 6
Mode = 8
Range = 14.75
From the above data, we can see that the Range of Mateo's Rocks is more as compared to the Isabella's Rocks.
Thus, Range can be used be used to support the claim that Mateo’s rocks generally weigh more than Isabella’s rocks.
So option D is the correct option
The answer is True hope this helps
