Answer: The answer is 31.25 because The mean of 16 items was found to be 30. So once you checked, it was that 2 items were wrongly taken as 22 and 18 instead of 32 and 28 respectively. Sum = mean no of items = 30 16 = 480
(32 +28) – (22 + 18) = 20
Correct mean = = 31.25

What value of x will make the equation below true?
4.5x=18
The functions g and h are given by g(x) = x + 1 and h(x) = x²
Find the values of x for which hg(x) = 3x² + x - 5
Answer:
x = - [tex]\frac{3}{2}[/tex] , x = 2
Step-by-step explanation:
To find h(g(x)) substitute x = g(x) into h(x) , that is
h(g(x))
= h(x + 1)
= (x + 1)²
= x² + 2x + 1
For h(g(x)) = 3x² + x - 5 , then
3x² + x - 5 = x² + 2x + 1 ← subtract x² + 2x + 1 from both sides
2x² - x - 6 = 0 ← in standard form
(2x + 3)(x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
2x + 3 = 0 ⇒ 2x = - 3 ⇒ x = - [tex]\frac{3}{2}[/tex]
x - 2 = 0 ⇒ x = 2
Suzy needs a raise in her allowance to buy the new iPhone. In order to do so, she must make a total average of 90 in all of her classes. Her science average is an 85, her math average is a 92, her history average is a 95, and her choir class is a 95. Her English class is undetermined as of now. What does Suzy have to make in English to be able to receive her raise?
Answer:
83
Step-by-step explanation:
Total averages from the known classes
85+92+95+95=367
367+83=450
Divide 450 by the number of classes she has(5)
=90

find area of trapezoid
Answer:
150 sqaure ft
Step-by-step explanation:
okay so the formula for area of a trapezoid is
1/2 (b1 + b2) h
so base one of 15 plus two of 10 os 25 ft
25 feet divided by 2 is 12.5 so 12.5 × 12 is 150
Which point is best represented by the ordered pair (2, -5.5)?
A point W
b point V
c point S
d point R
Answer:
B
Step-by-step explanation:
Answer:
The answer is A, Point W.
This is because (2, -5.5) is equal to (x, y). So, x would be 2, while point y will be -5.5. Point W represents this because it goes to 2 on the x axis, and down to -5.5 on the y axis.

Which of the following is the correct expanded form for the series below?

O-1-2-4-8-16
1-2 + 4-8 + 16
O-2-4-8-16
0-2 + 4 - 8 + 16
Answer:
-1-2-4-8-16
Step-by-step explanation
The solution is, 1-2 + 4-8 + 16, is the correct expanded form for the series Σ-2^n, n = 0 to 4.
What is an exponent in math?An exponent refers to the number of times a number is multiplied by itself. For example, 2 to the 3rd (written like this: 23) means: 2 x 2 x 2 = 8. 23 is not the same as 2 x 3 = 6. Remember that a number raised to the power of 1 is itself.
here, we have,
given that,
the series Σ-2^n, n = 0 to 4.
now, we have to find,
the correct expanded form for the series ,
as , we get,
the value of n = 0 to 4
so, putting the value of n = 0,1,2,3,4
we get the series as,
Σ-2^n
= -2^0 + (-2)^1 + (-2)^2 + (-2)^3 + (-2)^4
= 1 -2 + 4 - 8 +16
Hence, The solution is, 1-2 + 4-8 + 16, is the correct expanded form for the series Σ-2^n, n = 0 to 4.

What is the image of (-9,0) after a dilation by a scale factor of 2 centered at
the origin?
Answer:
The image is (-18,0)
Step-by-step explanation:
Here, we want to find the image of the given point after dilation by the given scale factor
Mathematically, given a point with the pre-image (x,y) going under the dilation of scale factor k, centered at the origin, the coordinates of the image will be;
(kx , ky)
Applying this in the given scenario, we have
(2(-9) , 2(0))
= (-18,0)
Cassandra must share 10 1/2 kg of cookies in 3/4 kg bags. How many bags will she complete?
Show the work.
Answer:
She will complete 14 bags of cookies
Step-by-step explanation:
Here, we want to know the number of bags to be completed by the sharing
What we have to do here is to divide the total weight of the bag of cookies by what each cookie bag can take
We have this as;
10 1/2 kg divided by 3/4 kg
= 21/2 divided by 3/4
= 21/2 * 4/3 = 14 bags

A grain silo is shaped like a cylinder with a height of 24 feet and a diameter of 10 feet. A farmer wishes to determine how many cubic feet of grain could fit in the silo.
What is the maximum amount of cubic feet of grain that the silo could hold?
O A 7539 cubic feet
B
2400 cubic feet
C
1884 cubic feet
O
D
600 cubic feet
Answer:
1884.95
Step-by-step explanation:
cylinder volume formula = [tex]\pi[/tex] * height * radius^2
diameter/2 = radius = 10/2 = 5
\pi * 24 * 25 = 600\pi cubic feet = 1885 when rounderd from 1884.955592
Answer:
1884

The question is in the picture
Answer:
y= -5x+7
Step-by-step explanation:
since it is parallel, the gradient is the same
m=-5
y=mX+C
y=-5x + c
sub in the coordinate to get the y intercept
(2)= -5(1)+c
2+5 = C
C=7
therefore the ans is :
y= -5x + 7

i need help telling if these are true or false
Answers:
FalseTrueFalseTrue======================================================
Explanations:
Point A is located at (0,1). It then moves to A' which is at (0,3). Note the y coordinate goes from y = 1 to y = 3, so the scale factor is 3/1 = 3 instead of 4. Therefore, the claim is false.Point A is at (-4,4). It moves to (-2,2). Each coordinate of (-4,4) is cut in half to get (-2,2). Cutting a value in half is the same as multiplying by 0.5, so point A fits the description. Let's find out if point B does as well. B is at (2,4) and it moves to B' (1,2); we can see that point B has its coordinates cut in half as well. Points C and D also work to fit the description (I'll let you check those coordinates) which means overall, quadrilateral ABCD dilates with a scale factor of 0.5 to get to quadrilateral A'B'C'D'. The answer here is "true".Point W is at the location (-1,1). Triple each coordinate to get (-3,3) which is where point W' should be located if we applied the dilation of scale factor 3. However, the diagram shows W' is not at (-3,3). It seems to be fairly close to (-2,2) if anything. We don't need to check the other points, but I recommend you do so just for practice. The answer here is "false".Because the scale factor is 0.25 = 1/4, this means "scale factor of 0.25" is the same as "scale factor of 1/4". That tells us to "multiply each coordinate by 1/4" which in turn is equivalent to "divide each coordinate by 4". Point E is at (-4,4) which moves to (-1,1) when we divide each coordinate by 4. Note how point E' is at (-1,1). So E moves in the proper way according to the instructions given to us. Points M, W and O also move in a similar fashion after we divide their coordinates by 4. The answer here is "true".what is 2.006 + 6.001?
2.006

HELP ASAP IM GIVING BRAINLIEST For our safety, it is important that drivers recognize a stop sign immediately. Stop signs are made with exact side and angle measurements to form a regular octagon. They are red so they are easy to see. The three lines drawn below are straight lines. Lines a and b are parallel.
