Answer:
15
Step-by-step explanation:
525/4 ÷ 35/4
=525/4 x 4/35
=525/35
=105/7
=15/1
=15
Answer:
Step-by-step explanation:
y₂₋y₁ / x₂-x₁ if you have two points you can plug them in and find the slope using this.
If it is on a graph you can look at two points and count the rise over run, for example if one point is (0, 0) and another is (2, 3) then from the first point it goes up 2 and over 3, so the slope would be 2/3
Answer:
First choice:
- <em><u>Most of the data in each plot are greater than 48.</u></em>
Explanation:
1. Boy's Heights.
Using the information you can create a frequency table:
Heigth Frequency
40 0
41 1
44 3
46 3
48 2
50 3
52 4
54 4
56 0
58 0
60 0
======
20 boys
2. Girl's Heights.
Similarly, create your frequency table:
Height Frequency
40 0
41 0
42 0
44 2
46 3
48 1
50 3
52 4
54 3
56 4
58 0
60 0
======
20 girls
<em>Which is a true statement for most of the data in each plot?</em>
<u><em>Most of the data in each plot are greater than 48.</em></u>
- Count the dots or add the frequencies from the tables.
- For boys, the frequency of points greater than 48 is: 3 + 4 + 4 = 11 which is more than half (there are 20 dots).
- For girls, the frequency of points greater than 48 is: 3 + 4 + 3 + 4 = 14, which is also more than half.
Hence, it is correct that most fo the data in each plot are greater than 48.
No it is not the worst subject
