Which expression represents a quadratic expression in complete factored form?
A.)(2x+4)(x-3)
B.)(x-1)(3x-9)
C.)(x+4)(x-3)
D.)(x-2)+(x+3)
Answer: C
Step-by-step explanation:
A) not completely factored because 2 can be factored out of 2x + 4
B) not completely factored because 3 can be factored out of 3x - 9
C) CORRECT
D) not factors because the terms are added instead of multiplied
Thus, (x - 2) + (x + 3) is not a quadratic equation. Then A, B, and C are the quadratic equation.
What is a Quadratic equation?It is a polynomial of maximum power 2. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.

A uniform distribution is defined over the interval from 6 to 10.
a. what are the values for a and b?
b. what is the mean of this uniform distribution?
c. what is the standard deviation?
d. show that the total area is 1.00 (use the area formula)
e. find the probability of a value more than 7 f. find the probability of a value between 7 and 9
Answer:
Refer below
Step-by-step explanation:
a) a and b are the lower and higher values of the interval for which uniform distribution is defined.
Here a= 6 and b =10
b) Mean of the uniform distribution= (a+b)/2 = (6+10)/2 =8
Or int x (1/4) dx = x^2/8 = 8
c) Variance of the uniform distribution = (b^2-a^2)/12 = (100-64)/12
= 36/12 =3
Std dev = sq rt of 3 = 1.732
d) To find total area
PDF of the distribution = 1/(b-a) = 1/4, 6<x<10
Area = \int 6 to 10 of 1/4 dx
= x/4
Subtitute limits
= (10-6)/4 =1
So total area = 1
d)P(X>7) = int 7 to 10 of 1/4 dx = 3/4
e) P(7<x<9) = Int 7 to 9 of 1/4 dx = 2/4 = 1/2
Probabilities are used to determine the chances of events
The values of a and b
The interval is given as 6 to 10.
So, the values of a and b are 6 and 10, respectively.
The mean
For a uniform distribution, the mean is:
[tex]\bar x = \frac{a + b}{2}[/tex]
So, we have:
[tex]\bar x = \frac{6 + 10}{2}[/tex]
[tex]\bar x = 8[/tex]
Hence, the mean is 8
The standard deviation
For a uniform distribution, the standard deviation is:
[tex]\sigma = \sqrt{\frac{b^2 - a^2}{12}}[/tex]
So, we have:
[tex]\sigma = \sqrt{\frac{10^2 - 6^2}{12}}[/tex]
[tex]\sigma = 2.31[/tex]
Hence, the standard deviation is 2.31
The total area
This is calculated as:
[tex]A = \int\limits^b_a \frac{1}{b - a}\ dx[/tex]
So, we have:
[tex]A = \int\limits^{10}_6 \frac{1}{10 - 6}\ dx[/tex]
[tex]A = \int\limits^{10}_6 \frac{1}{4}\ dx[/tex]
Factor out 1/4
[tex]A = \frac{1}{4}\int\limits^{10}_6 \ dx[/tex]
Integrate
[tex]A = \frac{1}{4} * x|\limits^{10}_6[/tex]
Expand
[tex]A = \frac{1}{4} * (10 - 6)[/tex]
[tex]A = 1[/tex]
Hence, the total area of the distribution is 1.00
The probability of a value more than 7
This is calculated as:
[tex]P(x > 7) = \frac{1}{4} * x|\limits^{10}_7[/tex]
Expand
[tex]P(x > 7) = \frac{1}{4} * (10 - 7)[/tex]
[tex]P(x > 7) = 0.75[/tex]
Hence, the probability of a value more than 7 is 0.75
The probability of a value between 7 and 9
This is calculated as:
[tex]P(7 < x < 9) = \frac{1}{4} * x|\limits^9_7[/tex]
Expand
[tex]P(7 < x < 9) = \frac{1}{4} * (9 - 7)[/tex]
[tex]P(7 < x < 9) = 0.50[/tex]
Hence, the probability of a value between 7 and 9 is 0.50

Write a division equation that has a solution of -20
Final answer:
A division equation that has a solution of -20 can be written by dividing a negative number by a positive number, such as -100 divided by 5.
Explanation:
To write a division equation with a solution of -20, you can choose any two numbers such that the division of one number by the other equals -20. For example, if we take -100 and divide it by 5, we get -20 as the solution. Thus, a sample division equation could be:
-100 / 5 = -20.
This is because when you divide a negative number by a positive number, the result is negative, and -100 \/ 5 leads to the desired solution of -20.

Step-by-step explanation: First multiply $3.00 by 10, so 3*10=30. Then you multiply $2.00 by 20, so 2*20=40. Then add those together 40+30=$70.
Select the action you would use to solve x/4 =16. Then select the property that justifies that action
Answer:
Given equation is:
x/4 = 16
Multiply both side of equation by 4
4* x/4 = 16*4
x= 64
Step-by-step explanation:
This is called Multiplication property of Equality.
If you multiply equation by a number on both sides, it remain same or balance.
The equation x/4 =16 is solved by multiplying both sides by 4, resulting in x = 64. This action is justified by the Multiplication Property of Equality.
Explanation:To solve the equation x/4 =16, the action one would use is to multiply both sides of the equation by 4. This operation will isolate the variable 'x'.
Your equation would thus be transformed as: 4 * (x/4) = 16 * 4. This simplifies to x = 64.
The property that justifies this action is the Multiplication Property of Equality, which states that multiplying both sides of an equation by the same non-zero number does not change the equality.

Fred spins a spinner with five equal spaces numbered 1 thru 5 and draws a card from a standard 52-card deck. What is the probability he spins a 3 or draws a king?
The probability of spinning a 3 or drawing a king is approximately 0.2769231, or around 27.69%.
Explanation:The question is asking us the probability that Fred spins a 3 from a spinner numbered 1 to 5 or draws a king from a standard 52-card deck. This involves the concept of probability, which requires us to look at the total possibilities and the outcome we are interested in.
Probability of spinning a 3 from the spinner numbered 1 to 5 is 1/5 or 0.2 because there is one favorable outcome (spinning a 3) out of 5 total outcomes (the numbers 1 to 5).
A standard 52-card deck has four kings (one from each suite; clubs, diamonds, hearts, and spades). So, the probability of drawing a king is 4/52, which also simplifies to 1/13 or approximately 0.0769231.
In this problem, we're looking at Fred spinning a 3 or drawing a king, hence we use the principle of addition in probability. The total probability will be the sum of the two individual probabilities, which is 0.2 + 0.0769231 = 0.2769231.
So, the probability that Fred spins a 3 or draws a king is approximately 0.2769231 or 27.69% when expressed as a percentage.

d
8x4 + 4x2 + 9
Answer:
a) 8x^2 + 4x + 9
Step-by-step explanation:
To find the total number of red and pink geranium pots, we need to add the two expressions given for the number of pots for red and pink respectively.
x (7x - 2) + (x + 3)^2

The vertex form of a parabola is
[tex]y=a(x-h)^2+k[/tex] ..... (1)
Where, (h,k) is vertex and a is a constant.
From the given graph it is clear that the vertex of the graph is (3,-7) and y-intercept is (0,2).
Substitute h=3 and k=-7 in equation (1).
[tex]y=a(x-3)^2-7[/tex]
The y-intercept is (0,2). So, substitute c=0 and y=2 in the above equation to find the value of a.
[tex]2=a(0-3)^2-7[/tex]
[tex]2+7=a(3)^2[/tex]
[tex]9=9a[/tex]
Divide both sides by 9.
[tex]1=a[/tex]
The value of a is 1.
Substitute a=1, h=3 and k=-7 in equation (1).
[tex]y=1(x-3)^2-7[/tex]
[tex]y=x^2-6x+9-7[/tex]
[tex]y=x^2-6x+2[/tex]
The equation of the parabola is [tex]y=x^2-6x+2[/tex].
Therefore the correct option is A.
