79.6 is the mean of given set of scores calculated by adding all the given scores and dividing it by number of scores which is 10.
To find the mean (average) of a set of scores, you need to add up all the values and then divide by the total number of values.
Let's calculate the mean of the math test scores you provided:
Math test scores: 92, 52, 80, 54, 75, 62, 78, 78, 95, 80
Add up all the scores:
92 + 52 + 80 + 54 + 75 + 62 + 78 + 78 + 95 + 80
= 796
Find the total number of scores:
There are 10 scores in the set.
Calculate the mean:
Mean = Sum of scores / Total number of scores
Mean = 796 / 10
Mean = 79.6
So, the mean of the math test scores is 79.6.

The value of Hector's house has increased by 5%.
His house is now valued at £609 000
Work out the value of the house before the increase.
Answer:
$580000
Step-by-step explanation:
To find decrease we simply reverse the operations of increase
increase is x x 1.05 = 609000
x = 609000 / 1.05 = 580000 initial value
x= $580000
proof
580000 x 1.05 = 609000 new value

point to a parallel line (8,-8); 9x - 4y= 7
Answer:
y = 9/4x - 26
Step-by-step explanation:
9x - 4y= 7
-4y = -9x + 7
y = 9/4x - 7/3
y = 9/4x + b
-8 = 9/4(8) + b
-8 = 18 + b
-26 = b

- 6x < 24
solve for x and what’s the solution?
Answer:
x > -4
Step-by-step explanation:
In order to get x by itself, you divide -6 on both sides. So, -6x divided by -6 = x and 24 divided by -6 equals -4.
However, the answer is not x < -4 because a rule of inequalities states that any time you divide or multiply both sides of an inequality by a negative number, the inequality sign is flipped. So, the answer is x > -4
Answer:
x > -4
Step-by-step explanation:
- 6x < 24
Divide each side by -6, remembering to flip the inequality
-6x/-6 > 24/-6
x > -4
Factor the expressions

Answer:
< b = 73°
Step-by-step explanation:
The angle with a measure of < 73° has the same measure as < b because they are vertical angles. Two angles are vertical angles if they are opposite angles formed by the intersection of two lines. Vertical angles are congruent.
Therefore, the correct answer is: < b = 73°

A box has a length of 30 inches, a width of 40 inches, and a height of 120 inches. Can a cylindrical rod with a length of 342.9 centimeters fit in the box?
Answer: 6 inches = 15.24 cm length
8 inches = 20.32 cm width
24 inches = 60.96 cm height
The diagonal along the side of the box = 20.32^2 + 60.96^2 = 4,129.024
square root (4,129.024) = 64.257 so the rod will fit diagonally.
