Regina kept track of the points she scored during her team’s first eight basketball games. What is Regina’s mean score?
Responses
A 3939
B 1616
C 3737
D 1313
E 17
Answers
Answer:
Mean = 16
Step-by-step explanation:
MEAN can be find bg the sum of all score divided by the amount of the score.
Mean = total amount / number of amount
Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39
= 128
number of amount = 2, 3, 5, 9, 17, 22, 31, 39
= 8
Then we can calculate mean as
Mean = 128/8
Mean = 16
2+3+5+9+17+22+31+39=128
128/8=16

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111
Answers
Here are the pairs matched with their products:
- (-5)(4.2) matches with -21
- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.

Considering area (A) of garden as 30 square feet:
30 = x(2x+7)
Now we need to expand it:
x(2x+7) = 2x^2 + 7x
2x^2 + 7x = 30
Adding this into an Algebra calculator gives us 5/2 or 2.5
So x = 2.5
To prove this:
2(2.5) + 7 = 12
14 * 2.5 = 30
(2x+7) x = 30
you can distribute to make this easier
2x^2 + 7x = 30
you can plug this into quadratic formula by setting the equation =0, so:
2x^2 +7x -30 = 0
where 2x^2 = a
7x = b
and -30 = c
you can plug this into your calculator and get an answer of
X = 2.5

Answers
5 guinea pigs weigh 144 ounces.
What is Unit of Measurement?A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity.
One pound is equal to 16 ounces. So, 1.8 pounds is equal to:
1.8 pounds × 16 ounces/pound = 28.8 ounces
Therefore, one guinea pig weighs 28.8 ounces.
To find out how much 5 guinea pigs weigh
Let us multiply the weight of one guinea pig by 5:
5 guinea pigs × 28.8 ounces/guinea pig = 144 ounces
Therefore, 5 guinea pigs weigh 144 ounces.

Answer:
33
Step-by-step explanation:
Arrange number in numerical order (least to greatest)
22, 26, 29, 33, 35, 39, 42,
Cross out a number from each side until there's one number left, in this case, it would be 33. This would only work if there is an even amount of numbers.
If there is an odd amount of numbers then do the previous steps and there would be two numbers left. Add them then divide by 2 and you've got your answer.
Explain the cosine rule and sine rule while also saying how to use it and provide examples (keep it in simple terms)
Answers
Answer:
Sure, I'll explain the cosine rule and sine rule in simple terms:
The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.
Here's an example of how to use the cosine
Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.
Using the cosine rule:
a^2 = b^2 + c^2 - 2bc * cosA
where A is the angle opposite side a, we can plug in our values and solve for a:
a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)
a^2 = 64 + 36 - 96 * 0.707
a^2 = 10.56
a = sqrt(10.56)
a = 3.25 (rounded to two decimal places)
Therefore, the length of side a is approximately 3.25 units.

multiply the bottom with -1 so that you have
positive or +9y
-2x-9y= -25
-1 times (-4x-9y= -23)
-2x-9y= -25
+4x+9y= +23
this equals

x = -1
put -1 where the x is in -2x-9y= -25 to get y
-2(-1) -9y = -25 =
+2 -9y = -25
-9y = -27
y = 3
6.
8x+ y= -16
-3x+ y= -5
multiply 8x+ y= -16 with +3 AND
multiply -3x+ y= -5 with -8
so you can cancel out the x's

-8 times (-3x+ y= -5)
8x+ y= -16
