A multiple-choice test with 50 questions has five possible choices for each question. There are 4 marks for each correct answer, -1 mark for each incorrect answer, and 0 marks for each unanswered question. What is the total score of a student with 35 correct answers, 10 incorrect answers and 5 unanswered questions?
Answer: 130 marks
Step-by-step explanation:
There are 4 marks for every correct answer and there are 4 marks for each correct answer:
= 35 * 4
= 140 correct marks
There are -1 marks for every incorrect answer and there are 10 incorrect answers:
= 10 * -1
= -10 marks
Total score = 140 - 10
= 130 marks
Answer:
130 marks

The two fractions when multiplied together make 3/4 are, 1/2 and 3/2.
What is a fraction?A fraction is written in the form of p/q, where q ≠ 0.
Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.
The first fraction can be 1/2 when multiplied by the second fraction 3/2.
Therefore,
The two fractions, when multiplied together make 3/4 is (1/2)×(3/2).

7 + x/5 = - 4 x=___ help
Answer:
x = -55
Step-by-step explanation:
7 + x/5 = -4
Combine the constants.
x/5 = -11
Multiply both sides by 5 to simplify the denominator.
x = -55
Check.
7 + (-55)/5 = -4
7 + (-11) = -4
7 - 11 = -4
-4 = -4
Your answer is correct.
Hope this helps!
Answer:
[tex]7 + \frac{x}{5} = - 4 \\ \frac{x}{5} = - 4 - 7 \\ = - 11 \\ x = - 11 \times 5 \\ = - 55[/tex]
The following graphs are transformations of f(x) = x^2.
Complete the boxes below to describe the transformations.
A(x) = f (x + _) + _
B(x) = f (x + _) + _
C(x) = f (x + _) + _
D(x) = f (x + _) + _
Step-by-step explanation:
Let's look at A(x) and see how it is different from f(x)
it is shifted downwards by 8 unitsit is not shifted to the left or the rightTherefore A(x) = f(x) - 8
Let's look at B(x) and see how it is different from f(x)
it is not shifted downwards or upwardsit is shifted to the left 7 unitsTherefore B(x) = f(x + 7)
Let's look at C(x) and see how it is different from f(x)
it is shifted upwards by 4 unitsit is shifted to right by 5 unitsTherefore C(x) = f(x - 5) + 4
Let's look at D(x) and see how it is different from f(x)
it is not shifted downwards or upwardsit is not shifted to right by 12 unitsTherefore D(x) = f(x - 12)

A baseball stadium holds 15,002 seats. The lower level has 50 fewer than three times as many seats as the upper level. The middle level has 40 more than twice as many seats as the upper level.
x + (2x + 40) + (3x – 50) = 15,002
The upper level has seats.
Answer:
The correct answer is 2,502 seats

how many square feet of outdoor carpet will we need for this hole
Answer:
42 ft²
Step-by-step explanation:
First of all, who makes a hole in this shape?
Anyways,
You're going to want to split the figure into multiple different shapes. We already have a triangle, so I would split the remaining shape into a rectangle and trapezoid.
We can find the area of the triangle easily with the equation 1/2(bh)
So
1/2(2 · 3)
1/2(6)
3
So the triangle is 3 ft²
Now we can find the area of the rectangle.
The measurements will be 3 and 7. It's just base x height so it'll be 21 ft²
Finally the trapezoid.
Base 1: 6
Base 2: 3
Height: 4 (11-7)
Formula: 1/2h (b1 + b2)
1/2 · 4 (6+3)
2(9)
18 ft²
Now just add them together:
3+21+18=42
Hence, your answer is 42 ft²
the perimeter of the floor of a room is 18 metre and its height is 3 cm what is the area of 4 walls of the room
Note: The height of the room must be 3 m instead of 3 cm because 3 cm is too small and it cannot be the height of a room.
Given:
Perimeter of the floor of a room = 18 metre
Height of the room = 3 metre
To find:
The area of 4 walls of the room.
Solution:
We know that, the area of 4 walls of the room is the curved surface area of the cuboid room.
The curved surface area of the cuboid is
[tex]C.S.A.=2h(l+b)[/tex]
Where, h is height, l is length and b is breadth.
Perimeter of the rectangular base is 2(l+b). So,
[tex]C.S.A.=\text{Perimeter of the base} \times h[/tex]
Putting the given values, we get
[tex]C.S.A.=18\times 3[/tex]
[tex]C.S.A.=54[/tex]
Therefore, the area of 4 walls of the room is 54 sq. metres.

The data to represent average test scores for a class of 16 students includes an outlier value of 78. If the mean, including the outlier of 78, equals 84, which statement is always true about the new data when the outlier is removed?
The mean would increase.
The mean would decrease.
The median would increase.
The median would decrease.
Answer:
Given that The data to represent average test scores for a class of 16 students includes an outlier value of 78.
We can find sum of all 16 test scores = 84(16) = 1344
Outlier found = 78
If outlier is removed new sum = 1344-78 = 1266
Number of entries without outlier = 15
New average = 1266/12 =84.4
We find that average of new data increases.
Also whenever we remove outlier std deviation also would be reduced.
Step-by-step explanation:
Answer:
The mean would decrease.
Step-by-step explanation:
Without the outlier, the mean decreases. The median stays the same with or without the outlier.

For a walk-a-thon a sponsor committed to give you a flat free of $5 plus $2 for every mile m you walk
Answer:
$45
Step-by-step explanation:
THIS IS THE COMPLETE QUESTION BELOW;
For a walk-a-thon a sponsor committed to give you a flat fee of $5 plus $2 for every mile you walk. If you walk for 20 miles, what is the total amount you will collect from your sponsor at the end of the walk-a-thon?
$5 was given for participants of the walk-a-thon.
$2 was given for every miles won
Then, for "y" number of miles, the the amount that can be won is ( 2×y)= 2y
The Total amount that can be given
= (5 + 2y)
Where "y" is the miles value
Then, if you walk for 20 miles, The Total amount that can be given
= 5 + 2(20)
= 5+ 40
= $45
