The test scores of five students for the first two test of the semester are shown in the table below.
Answer:
A
Step-by-step explanation:
Take test score from Test 1 and add them all together and divide by the number of test
ex) 77+82+69+85+93=406
406/5= 81.2
Then repeat with Test 2
ex) 75+76+71+68+72=362
362/5= 72.4
Therefore the MAD of Test 1 > MAD of Test 2
the answer is A.
Step-by-step explanation:
Add the test scores of the first test together then add the test scores of the second test together then compare and contrast.

Step-by-step explanation:
What is the equation in vertex form of the quadratic function with a vertex at (-1,-4) that goes through (1,8)?
Answer:
G
Step-by-step explanation:
vertex formula = a(x-h)^2 + k
vertex is (h, k) so (-1, -4) means
y = a(x+1)^2-4
passes through (1, 8) so when x = 1 and y = 8
8 = a(1+1)^2-4 = 4a - 4
4a = 4
a = 1

The volume of the rectangular prism can be found using the 6x6x7 option (A) 6x6x7 is correct.
What is a rectangular prism?It is defined as the six-faced shape, a type of hexahedron in geometry.
It is a three-dimensional shape. It is also called a cuboid.
It is given that:
A rectangular prism is given in the picture with dimensions:
As we know, volume can be defined as a three-dimensional space enclosed by an object or thing.
The volume of the rectangular prism is given by:
V = L×W×H
Here, V is the volume of the rectangular prism
L is the length of the rectangular prism
W is the width of the rectangular prism
H is the height of the rectangular prism
From the figure:
L = 6 cm
W = 7 cm
H = 6 cm
V = 6x7x6
or
V = 6x6x7
Thus, the volume of the rectangular prism can be found using the 6x6x7 option (A) 6x6x7 is correct.

Step-by-step explanation:
Ms. Edwards can spend, at most, $250 on new books for the school library. She will buy a reference book on birds for $30 and a reference book on the planets for $14.95. Let x represent the amount of money Ms. Edwards can spend on other books. Write an inequality that correctly describes this situation.
Answer:
x ≤ 205.05
Step-by-step explanation:
x = dollar amt remaining for other books
30 + 14.95 + x ≤ 250
44.95 + x ≤ 250
x ≤ 205.05
x ≤ $205.05 is an inequality that correctly describes this situation.
What is algebraic Expression?Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression. In the phrase 4m + 5, for instance, the terms 4m and 5 are separated from the variable m by the arithmetic sign +.
Let's use x to represent the amount of money Ms. Edwards can spend on other books.
We know that Ms. Edwards can spend at most $250 in total and that she will already spend $30 + $14.95 = $44.95 on the reference books on birds and planets.
Therefore, the amount she has left to spend on other books is:
x = $250 - $44.95
x = $205.05
Ms. Edwards can spend up to $205.05 on other books.
To write this as an inequality, we can use the less than or equal symbol since Ms. Edwards cannot spend more than $205.05:
x ≤ $205.05
Therefore, the inequality that correctly describes this situation is:
x ≤ $205.05

Round your answer to the nearest cent. Show your work?
Answer:
$92.60
Step-by-step explanation:
7($5.99) + 7($6.49)=$41.93
$41.93 + $45.43 = $87.36
$87.36 + ($87.36 × 6%=0.06)

A loading ramp is extended from the back of a truck to form a 30° angle with the ground. The truck and the ramp are both on level ground. If the length of the ramp is x feet, how high is the back of the truck from the ground?
A) 2x feet
B) x√3/2
C) x√3
D) x/2
Answer:
Height between ground and truck = 5.5 feet
Step-by-step explanation:
Given:
Angle of elevation = 30°
Length of the ramp = 11 feet
Find:
Height between ground and truck
Computation:
Length of the ramp = Hypotenuse
Height between ground and truck = Perpendicular
Sin θ = Perpendicular / Hypotenuse
Sin 30 = Height between ground and truck / Length of the ramp
0.5 = Height between ground and truck / 11
Height between ground and truck = 0.5 x 11
Height between ground and truck = 5.5 feet

is 4 a factor of 93 explain in words
IM MAKING THE POINTS HIGH
No 4 is not a factor of 93 :)
let me know if this helped<3
Explanation: a factor is whether or not a number can be multiplied with another number, 4 cannot be multiplied by any number to evenly come out as 93, the way you can check this is by dividing 93 by 4, if it comes out as a whole number with no decimal or remainder than the number is a factor if it has a decimal or remainder it is not a factor
Answer:
No.
Step-by-step explanation:
The first method entails simply listing all factors of 93 and then seeing if 4 is one of them. The factors of 93 are 1, 3, 31, and 93. Looking at the list, you see that 4 is not on the list, and the answer to "is 4 a factor of 93?" is therefore no. For the second and perhaps easier method, we divide 93 by 4 to see if the quotient is a whole number or fractional number. If the quotient is a whole number, then 4 is a factor of 93. If the quotient is a fractional number, then 4 is not a factor of 93. 93 divided by 4 is 23.25 which is a fractional number. Thus, once again, the answer to "Is 4 a factor of 93?" is no.

Mateyo is building a rectangular prism with a volume of 1000 cubic units. The height of the prism is 10 units. Mateyo claims that the base of the prism must be a square. Draw a base for th rectangular prism that shows that Mateyo is not correct. Remember to label the units.
Answer:
See attachment for drawing
Step-by-step explanation:
Given
[tex]Volume = 1000[/tex]
[tex]Height = 10[/tex]
Required
Drawing that proves Mateyo wrong
First, calculate the base area
[tex]Volume = Base\ Area * Height[/tex]
This gives:
[tex]1000= Base\ Area * 10[/tex]
Divide both sides by 10
[tex]100= Base\ Area[/tex]
Rewrite as:
[tex]Base\ Area = 100[/tex]
The base area is calculated as:
[tex]Base\ Area = Length * Width[/tex]
So, we have:
[tex]Length * Width = 100[/tex]
Mateyo's claim can be interpreted as:
[tex]Length = Width = 10[/tex]
However, there are other possible cases such that:
[tex]Length \ne Width[/tex]
For instance:
[tex]Length = 20[/tex]
[tex]Width = 5[/tex]

PLEASE HELP WITH ANSWER ITS DUE TOMORROW
Answer:
A: 46 meters at 3 seconds
B: 0 meters at 6.033 seconds
C. It depends where the tree is
D. 6.033 seconds
Step-by-step explanation:
A. To find max height, we need to find the vertex.
We can do this by using vertex from y=a(x-h)+k for y=a^2+b^2+c^2
h(t) = -5t^2+30t+1
h(t)+45 = - 5x^2+30x+45+1
h(t)+45= -5(x^2-6x-9)+1
h(t)+45 = -5(x-3)^2+1
h(t) = -5(x-3)^2+46
Hence, the max height is 46 at 3 seconds
B. The minimum height is 0 meters because of the problem
C. It depends because the parabola intersects x=10 in 2 places meaning that you need the tree to be in either of these two places to intercept the horseshoe
D. -5x^2+30x+1=0
5x^2-30x-1=0
x= (30+-sqrt(30^2-4*5*-1))/2*5
x=(30+-sqrt920)/10
x=3+-2sqrt230/10
x=3+-sqrt230/5
This means that x = -0.033 or 6.033. Negative value doesn't make sense so it's 6.033 seconds
17. What are the three angle measures in the triangle shown below?
Answer:
Option (1)
Step-by-step explanation:
By using triangle sum theorem in the given triangle,
(5x - 7)° + (11x - 4)° + (3x + 1)° = 180°
(5x + 11x + 3x) - (7 + 4 - 1) = 180
19x - 10 = 180
19x = 190
x = 10
Therefore, (3x + 1)° = 30 + 1
= 30°
(11x - 4)° = 110 - 4
= 106°
(5x - 7)° = 43°
Therefore, Option (1) will be the correct option.
