It is more likely that the Grade 7 pupils will be in the science club because 70 is more than 55.
What is a conditional relative frequency?It is defined as the frequency that can be evaluated by the two-way frequency table. Usually, we can obtain this frequency by dividing the frequency that is not in the total frequency cell by the total frequency.
As we can see in the table:
Grade 7 = 10/11
Grade 8 = 5/7
Or after making the common denominator:
Grade 7 = 70/77
Grade 8 = 55/77
Thus, it is more likely that the Grade 7 pupils will be in the science club because 70 is more than 55.

Please help me with this question !!!!!!!!!!
Answer:
1) 7/8
2) 0. 9
3) 88%
Step-by-step explanation:
total CDs = 2 + 9 +5 = 16
probability of Comedy is 2 out of the total 16
= 2/16
probability of not picking one would be 1 - 2/16 = 14/16 = 7/8
7 divided by 8 = 0.875 which rounds to 0.9
0.875 x 100 gives the percentage of 87.5% which rounds to 88%

Mr. Morris is going to save money and replace his sailboat's mainsail himself. He must determine the area of the mainsail in order to buy the correct amount of material. Calculate the area of the parallelogram to determine how much material should be purchased. Be sure to explain how to decompose this shape into rectangles and triangles. Describe their dimensions and show your work.
Welll....from the diagram, you can see you have two triangles (one on each side)
area of triangle = 1/2 base*height = 1/2 * 2 x 15 = 15ft2 each then you are left with a rectangle 13 ft x 15= 195 ft2
195+15+15=
225 ft2 <----- ANSWER
The area of the parallelogram is equal to 300 square feet.
Given the following data:
Width of parallelogram = 20 feet.Base of triangle = 4 feet.Height of triangle = 15 feet.To calculate the area of the parallelogram:
First of all, we would determine the area of the triangles.
Note: There are two (2) triangles that can be cut-off the given parallelogram.
The formula for the area of a triangle.Mathematically, the area of the triangle is given by the formula:
[tex]Area=\frac{1}{2} \times base \times height\\\\Area=\frac{1}{2} \times 4 \times 15\\\\Area=2 \times 15[/tex]
Area = 30 [tex]ft^2[/tex]
For the two (2) triangles:
[tex]Area = 2 \times 30[/tex]
Area = 60 [tex]ft^2[/tex]
For the rectangle left:
Length = 15 ft.Width = 20 - 4 = 16 ft.[tex]Area = length \times width\\\\Area = 15 \times 16[/tex]
Area = 240 [tex]ft^2[/tex]
Now, we can calculate the area of the parallelogram:
[tex]Area \;of \;parallelogram = 60 + 240[/tex]
Area of parallelogram = 300 [tex]ft^2[/tex]

What is 12 1/2% less than $80? I hope you're havin' a good day.
Answer:
10
12.5% less than 80 = 10
Step-by-step explanation:
Step 1: Our output value is 80.
Step 2: We represent the unknown value with x.
Step 3: From step 1 above, 80=100%
Step 4: Similarly, x=12.5%
Answer:
70
Step-by-step explanation:
To answer this question, we have to find out what is 12 1/2% of 80 and subtract it from 80. 12 1/2% is the same as 0.125, or 1/8. 1/8 of 80 is
1/8 * 80 = 10, 80 - 10 = 70

Here are the low temperatures (in degrees Fahrenheit) for one week in Montreal, Canada:
-3.5 ℉
5 ℉
1.5 ℉
-0.5 ℉
-2℉,
2.5℉
-4 ℉
Part 1: Weather Analysis
1. Plot and label the temperatures on a number line. You can create it by using a drawing program, by drawing it by hand and sending in a picture, or by describing in detail how the completed number line should look.
2. Compare the weather on two different days using an inequality. Then see if their comparisons change by finding the absolute value of each.
Day 1: Day 2: Comparison of Day 1 and Day 2: ____ < _____ or _____ > _______ Comparison of days with absolute value: ____ < _____ or _____ > _______
3. Which temperature during the week is the closest to 0? Explain how you decided this using absolute value.

Answer: 17
Step-by-step explanation:The other side is the same length. So its 17 :)
Answer:
18.3 = The third side
Step-by-step explanation:
Using Pythagorean Theorem; since the triangle is a right angled triangle.
Pythagorean Theorem states: A² + B² = C² (Where C is the hypotenuse, the line on the triangle opposite to the labeled right angle of the triangle, A and B would be the other 2 sides).
=> A² + B² = C²
=> 17² + B² = 25²
=> 289 + B² = 625
=> B² = 625 - 289
=> B² = 336
=> [tex]\sqrt{B^2}[/tex] = [tex]\sqrt{336}[/tex]
=> B = [tex]\sqrt{336}[/tex]
=> B = 18.3
