A committee consisting of 4 males and 3 females is to be formed. In how many ways can the committee be formed if there are 8 females and 6 males available?
- A.
840
- B.
820
- C.
780
- D.
760
Correct Answer
A. 840Explanation
The committee can be formed by selecting 3 females out of 8 available females and 4 males out of 6 available males. The number of ways to select 3 females out of 8 is given by the combination formula, which is 8C3 = 8! / (3! * (8-3)!) = 8! / (3! * 5!) = (8 * 7 * 6) / (3 * 2 * 1) = 56. Similarly, the number of ways to select 4 males out of 6 is given by the combination formula, which is 6C4 = 6! / (4! * (6-4)!) = 6! / (4! * 2!) = (6 * 5) / (2 * 1) = 15. Therefore, the total number of ways to form the committee is 56 * 15 = 840.Rate this question:

There are 10 green balls, 8 white balls, and 6 blue balls in a jar. What is the probability that when a ball is picked from the bag, it is a non-white ball?
- A.
1/4
- B.
2/3
- C.
7/12
- D.
1/3
Correct Answer
B. 2/3Explanation
The probability of picking a non-white ball can be calculated by dividing the number of non-white balls by the total number of balls. In this case, there are 10 green balls and 6 blue balls, which makes a total of 16 non-white balls. The total number of balls in the jar is 10 + 8 + 6 = 24. Therefore, the probability of picking a non-white ball is 16/24, which simplifies to 2/3.Rate this question:

Which of the following polynomial equation with roots -1, 1, and 4?
- A.
P(x) = x3 – 4x2 – 2x + 4
- B.
P(x) = x3 – 4x2 – 4x – 4
- C.
P(x) = x3 – 4x2 + x + 4
- D.
P(x) = x3 – 4x2 – x + 4
Correct Answer
D. P(x) = x3 – 4x2 – x + 4Explanation
The given polynomial equation has roots -1, 1, and 4. To find the correct equation, we need to check which equation gives us these roots when plugged in. By substituting -1, 1, and 4 into each equation, we find that only P(x) = x3 – 4x2 – x + 4 gives us the desired roots. Therefore, P(x) = x3 – 4x2 – x + 4 is the correct equation.Rate this question:

What are the roots of the quadratic equation b2 – 5b – 36 = 0?
- A.
(9, 4)
- B.
(9,-4)
- C.
(-9, -4)
- D.
(-9,4)
Correct Answer
B. (9,-4)Explanation
To find the roots of the quadratic equation b^2 - 5b - 36 = 0, we can use the quadratic formula. The quadratic formula states that for an equation of the form ax^2 + bx + c = 0, the roots can be found using the formula:
x = (-b ± √(b^2 - 4ac)) / 2a
In this case, our equation is b^2 - 5b - 36 = 0. So, we have:
a = 1 b = -5 c = -36
Plugging these values into the quadratic formula, we get:
b = [5 ± √((-5)^2 - 4(1)(-36))] / 2(1) b = [5 ± √(25 + 144)] / 2 b = [5 ± √169] / 2 b = [5 ± 13] / 2
Now, we have two possible roots:
b = (5 + 13) / 2 = 18 / 2 = 9
b = (5 - 13) / 2 = -8 / 2 = -4
Therefore, the roots of the quadratic equation b^2 - 5b - 36 = 0 are 9 and -4.Rate this question:

A square with a side of 12 cm and a rectangle with a width of 8 cm have the same area. What is the length of the rectangle?
- A.
16 CM
- B.
17 CM
- C.
18 CM
- D.
20 CM
Correct Answer
C. 18 CMExplanation
The area of a square is calculated by multiplying the length of one side by itself. In this case, the side of the square is given as 12 cm, so the area of the square is 12 cm * 12 cm = 144 cm^2. The area of a rectangle is calculated by multiplying its length by its width. Since the rectangle and the square have the same area, we can set up the equation 144 cm^2 = length of rectangle * 8 cm. Solving for the length of the rectangle, we find that it is 18 cm.Rate this question:

In square FATE, the measure of angle F is 4x + 30. What is the value of x?
- A.
21 degrees
- B.
19 degrees
- C.
15 degrees
- D.
13 degrees
Correct Answer
C. 15 degreesExplanation
The measure of angle F in square FATE is given as 4x + 30. To find the value of x, we can equate this expression to the given answer choices and solve for x. By substituting 15 degrees for x in the expression 4x + 30, we get 4(15) + 30 = 60 + 30 = 90 degrees. Since 90 degrees is not one of the answer choices, we can conclude that the given answer of 15 degrees is incorrect. Therefore, the correct answer cannot be determined from the information provided.Rate this question:

The computation for profit in a textile store is presented by the mathematical model P(x) = 3x2 + 6x – 120,000 where x is the number of meters being sold. What is the computed profit if the number of meters being sold is 250?
- A.
70,000.00
- B.
69000.00
- C.
68, 000.00
- D.
67,000.00
Correct Answer
B. 69000.00Explanation
To find the computed profit when 250 meters are being sold, we can substitute the value of x = 250 into the given mathematical model:
P(x) = 3x^2 + 6x - 120,000
So,
P(250) = 3(250)^2 + 6(250) - 120,000
Now, let's compute:
P(250) = 3(62500) + 1500 - 120,000 = 187500 + 1500 - 120,000 = 189000 - 120,000 = 69,000
Therefore, the computed profit when 250 meters are being sold is $69,000.Rate this question:

Which of the following function will cross the x-axis thrice?
- A.
P(x) = (x2-1)(x2 – 5x + 6)
- B.
P(x) = (2x2 – 5x + 2) (x+3)
- C.
Both A and B
- D.
Neither A Nor B
Correct Answer
B. P(x) = (2x2 – 5x + 2) (x+3)Explanation
The function P(x) = (2x^2 - 5x + 2) (x+3) will cross the x-axis thrice because it is a quadratic function with a leading coefficient of 2, which means it opens upwards. The quadratic factor (2x^2 - 5x + 2) will have two x-intercepts, and the linear factor (x+3) will have one x-intercept. When multiplied together, these factors will result in a function that crosses the x-axis three times.Rate this question:

Plug in the values:
C(8, 6) = 8! / (6!(8 - 6)!)
Calculate the factorials:
8! = 8 * 7 * 6!
6! = 6 * 5 * 4 * 3 * 2 * 1
Now calculate:
C(8, 6) = (8 * 7 * 6!) / (6! * 2!)
Simplify:
C(8, 6) = (8 * 7) / (2 * 1)
C(8, 6) = 56 / 2
C(8, 6) = 28

Correct Answer
D. 30Explanation
The expression 10!/(4!7!) can be simplified as follows:
10! = 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 4! = 4 × 3 × 2 × 1 7! = 7 × 6 × 5 × 4 × 3 × 2 × 1
Substituting these values into the expression:
10!/(4!7!) = (10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1) / [(4 × 3 × 2 × 1) × (7 × 6 × 5 × 4 × 3 × 2 × 1)]
Many terms cancel out in the numerator and the denominator:
(10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1) / [(4 × 3 × 2 × 1) × (7 × 6 × 5 × 4 × 3 × 2 × 1)] = (10 × 9 × 8) / (4 × 3 × 2) = (720) / (24) = 30

- B.
3a2 + 5a + 1
- C.
6a2 + 5a + 1
- D.
6a2 + 5a + 3
Correct Answer
C. 6a2 + 5a + 1Explanation
(6a^2 + 5a + 1) is divisible by (3a + 1), because when we divide it by (3a + 1), we get no remainder:
(6a^2 + 5a + 1) ÷ (3a + 1) 2(3a^2 + 3a) + 1 = (2 * 3a^2) + (2 * 3a) + 1
When we divide the first two terms, we get a quotient of (2 * 3a^2) + (2 * 3a), which is the same as (3a^2 + 3a) multiplied by 2. Therefore, (3a + 1) is a factor of (6a^2 + 5a + 1).Rate this question:

What is the value of P(8, 5)? (P = Permutation)
- A.
2580
- B.
1120
- C.
860
- D.
6720
Correct Answer
D. 6720Explanation
The value of P(8, 5) represents a permutation of 8 items taken 5 at a time. In permutation, the order of selection matters. The formula for calculating permutations is:
P(n, r) = n! / (n - r)!
Where:
P(n, r) represents the number of permutations of n items taken r at a time.
n! (read as "n factorial") represents the product of all positive integers from 1 to n.
In this case, for P(8, 5):
P(8, 5) = 8! / (8 - 5)! P(8, 5) = 8! / 3!
Now, calculate the factorials:
8! = 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 = 40,320 3! = 3 × 2 × 1 = 6
Now, divide 8! by 3!:
P(8, 5) = 40,320 / 6 = 6,720
So, P(8, 5) = 6,720.Rate this question:

A bag contains 5 red marbles, 3 blue marbles, and 2 green marbles. If two marbles are drawn at random without replacement, what is the probability that both marbles are blue?
- A.
3/10
- B.
9/100
- C.
1/15
- D.
3/50
Correct Answer
C. 1/15Explanation
To find the probability of drawing two blue marbles without replacement, we need to consider the probability of each draw separately.
First draw: The probability of drawing a blue marble is 3 (number of blue marbles) / 10 (total number of marbles).
Second draw: After taking out one blue marble, there are only 2 blue marbles left and 9 total marbles. So, the probability of drawing another blue marble is 2/9.
To get the probability of both events happening, we multiply the individual probabilities: (3/10) * (2/9) = 6/90 = 1/15.Rate this question:
