B. Expression 1. Sarah can’t apply the Distributive Property if there are three addends.
C. Expression 2. Sarah can’t combine -4 and -6. She must combine -4 with 8.
D. Expression 3. Sarah applied the Distributive Property but incorrectly multiplied 1/2 (-6) .
Answer:
The answer is d
Step-by-step explanation:
The step expression 3 is incorrect, there should be -3 in place of +3.
What is expression?An expression in maths, a statement involving at least two different numbers (known or unknown) and at least one operation.
Given is an expression, 1/2{-4+8+(-6)}
On solving, we get,
1/2{-4+8+(-6)}
= 1/2(-4) + 1/2(8) +1/2(-6)
= 1/2{-4+(-6)} + 4
= -2+4-3
When we will divide, -6 by 2, we will get -3 and Sarah used +3 which made her expression 3 incorrect.
Hence, The step expression 3 is incorrect, there should be -3 in place of +3.

A class of 37 students took a test worth 100 points. The five-number summary of their scores is 55, 67, 73, 81, 98. Give an interval of typical test scores that represents the middle 50% of grade distribution.
Answer:
(67, 81)
Step-by-step explanation:
Given that :
Five number summary of scores :
55, 67, 73, 81, 98
Five number summary :
Minimum = 55
Lower quartile = 67
Median = 73
Upper quartile = 81
Maximum = 98
Interval which represents the middle 50% of the grade distribution is the interquartile range, which is the difference between the upper and lower quartile
Hence the interval is ;

what is the square root of 83, 10, 63, and 99?
Answer: square root of 10 - 100 3.162
√63 =√32⋅7=√32⋅√7=3√7.
Thus, the square root of 99 lies somewhere between 9.9 and 10. Choosing an estimate in the middle of this range, we know that sqrt(99) is approximately equal to 9.95, with an error of not more than 0.05.
Step-by-step explanation:
Explanation: √83 is an irrational number. You won't be able to simplify it any further either, since it doesn't have any perfect square factors.

What is an equation of the line that passes through
the point (-2,3) and is parallel to the line whose
equation is y = {x – 4?
Answer:
B
Step-by-step explanation:
For the perpendicular of an equation you need to flip the fraction and change the sign from positive to negative or if it's negative to positive. 3/2 is changed to -2/3 which when multiplied by -2 gives you 4/3 and 4/3+5/3 is equal to 3.
Mike has a loan of $36,320. This loan has a simple interest rate of 6% per year. What is the
amount of interest that will be charged on this loan at the end of the first year?
Answer:
$2,179.2Step-by-step explanation:
Given;
Loan = $36,320 (Principal)
Rate R = 6% = 0.06
Time T = 1year
Required
Interest that will be charged on this loan at the end of the first year
Using the formula for calculating simple interest as;
SI = PRT/100
SI = 36,320 * 6 * 1/100
SI = 0.06 * 36,320
SI = $2,179.2
Hence the amount of interest that will be charged on this loan at the end of the first year is $2,179.2

Net value (or the total of everything) is total revenue - total expenses.
Total revenue = $9,550
Total revenue = $9,000 + $200 = $9,200
Net value = $9550 - $9200 = $350
Since the total revenue is greater than the expenses, it is a profit.
So, Mia had a profit of $350
