6. Find the mode of the set of data: 55, 56, 45, 51, 60, 53, 63, 70, 62, 58, 63

6. 63(Could have counted wrong. Mode is the number that appears the most in a set of data)
7. Couldn't solve sorry!
First, set up a proportion. 10.3% is the percentage of students who cancelled, but the question is asking for the students who are attending, so let’s use 89.7% to make it easier. The proportion would be x over 58 is equal to 89.7% over 100%. Multiply 58 by 89.7, giving you 5,202.6. Next, take 5,202.6 and divide it by 100. This should give you 52. 026, but it’s best to round this to 52. 52 students actually attend the art class, making this your final answer.
Answer:
Amy worked for 128 hours while Brayden worked for 112 hours
Step-by-step explanation:
Given
Let A represents Amy and B represents Brayden
A = 16 + B ------(1)
A:B = 8:7------- (2)
Required
Find A and B;
Convert (2) to fractions
Cross Multiply
Substitute A = 16 + B in the above expression
Open Bracket
Subtract 7B from both sides
Recall that A = 16 + B
Hence, 
<em>This implies that Amy worked for 128 hours while Brayden worked for 112 hours</em>
Answer:
Add 36. The factored form is 
.
Step-by-step explanation:
A perfect square is a trinomial that factors into the form 
. To find the value to add to it divide 20 by 2 and square it.
12/2 = 6
6*6 = 36
This means c=36. The factored form is .
Answer:
D
Step-by-step explanation:
--2x-2x-2x-2 = -16
2x (-2x-2x-2) = -16
-2x-2= 4
4x-2+8= 0
-16+-16+4+0 = -32+4
= -36
