Answer:
The answer should be the range of the 7th grade data is greater than the range of the 8th grade data
Step-by-step explanation:
You can find the range of data by subtracting the lowest value from the largest value, looking at the chart:
7th Graders: Lowest is 10, Highest is 80
Range for 7th Graders is 70
8th Graders: Lowest is 15, Highest is 75
Range for 8th Graders is 60
Answer:
9.24 m to 2 DP's.
Step-by-step explanation:
Consider the right triangle formed from a side , altitude and 1/2 the base.
By pythagoras:
x^2 = 8^2 + (0.5x)^2 where x is the length of each side.
x^2 - 0.25x^2 = 64
0.75x^2 = 64
x^2 = 64/0.75 = 85.3333.
x = 9.2376 m.

Answer:
x = 2.3
Step-by-step explanation:
Since we know all three sides, what we do here is multiply side a & b's lengths together and divide by the hypotenuse. (a + b)/c
(2.5 * 6)/6.5
<em>Step 1: Multiply 2.5 by 6 to get 15.</em>
15/6.5
<em>Step 2: Convert 6.5 into a whole number by multiplying it by 10. Make sure to do that to the 15 as well.</em>
150/65
<em>Step 3: 150/65 simplifies to 30/13 (GCF: 5).</em>
30/13
<em>Step 4: 30/13 becomes 2 4/13.</em>
2 4/13
<em>Step 5: 2 4/13 rounds to 2.3</em>
2.3 is the value of x.
