Answer:
Students in 7th grade took a standardized math test that they also had taken in 5th grade. The results are shown on the dot plot, with the most recent data shown first.
Find and compare the means to the nearest tenth.
7th-grade mean:
✔ 16
5th-grade mean:
✔ 13.4
What is the relationship between the means?
✔ The 7th-grade mean is about 2.5 points higher.
Step-by-step explanation:
Mean for 7th Grade Students is: 16
Mean for 5th Grade Students is: 13.4
Comparing the means, the mean for 7th grade students is 2.6 higher than 5th grade students.
What is the Mean of a Data Distribution?The mean is the average of the data set, that is the sum of each data value divided by the number of data points.
Given that, 7th Grade Students in 7th grade took a standardized math test that they also had taken in 5th grade.
Mean for 7th Grade Students:
Mean = [10 + 11 + (2 × 12) + 13 + 14 + (2 × 15) + (3 × 16) + (3 × 17) + (2 × 18) + (2 × 19) + (3 × 20)]/21
Mean = 335/21
Mean = 15.95 = 16
Mean for 5th Grade Students:
Mean = [8 + (2 × 9) + (2 × 10) + (2 × 11) + (2 × 12) + (2 × 13) + 14 + (3 × 15) + (2 × 16) + 17 (2 × 18) + 19
Mean = 281/21
Mean = 13.38 = 13.4
The difference between their means = 16 - 13.4 = 2.6.
Hence, Mean for 7th Grade Students is: 16
Mean for 5th Grade Students is: 13.4
Comparing the means, the mean for 7th grade students is 2.6 higher than 5th grade students.

Relate these 2 equations together: 5*5, 5+5+5+5+5 *
Your answer
Answer:
5x5 is 25 and 5+5+5+5+5 is also 25 please give brainliest
Step-by-step explanation:
Answer:
5*5=5+5+5+5+5
Step-by-step explanation:
Both are equivalent because both include adding 5 fives together, if you were to space out the 5*5 it would be equivalent. Also, if you add 5+5+5+5+5 it would equal 25 and 5*5=25. That is why they are equivalent. Hope this helps, let me know if correct, and have a great day!!

Step-by-step explanation:
7 - (2m - 5)
Hey there!
In order for us to find out which one is equivalent to 5 – 2m , we can go through all of your options to see which one gives us that!
“Equivalent to 5 – 2m”
Option A.
7 – 2(m + 1)
Distribute
7 – 2(m) + 2(1)
7 – 2m + 2
COMBINE LIKE TERMS
7 – 2 = 5
Option Answer: 5 – 2m
Option A can be a possible ANSWER ✅
Option B.
7 - (2m - 5)
DISTRIBUTE
7 – 2m + 5
COMBINE LIKE TERMS
7 + 5 = 12
–2m = –2m
Option Answer: –2m + 12
Option B CAN’T possibly be your ANSWER ❌
Option C.
7 - 2(m - 2)
DISTRIBUTE
7 - 2(m) + (–2)(–2)
7 – 2m + 4
COMBINE YOUR LIKE TERMS
7 + 4 = 11
–2m = –2m
Option answer: –2m + 11
Option C. CANT possibly be your ANSWER ❌
Now that we have went through ALL of your choices, this leaves “Option A” as your answer
Answer: Option A). 7 - 2(m + 1) ☑️
