Answer:
The probability that a person likes the color blue given that they are a woman=0.25%
Step-by-step explanation:
We are given that
The probability that a women likes the color blue=10%=[tex]\frac{10}{100}=0.1[/tex]
The probability of being a women=40%=[tex]\frac{40}{100}=0.4[/tex]
We have to find the probability that a person likes the color blue given that they are a woman.
We know that
Conditional probability formula
[tex]P(A/B)=\frac{P(A\cap B)}{P(B)}[/tex]
The probability that a person likes the color blue given that they are a woman
=[tex]\frac{0.1}{0.4}[/tex]
[tex]=\frac{1}{4}=0.25[/tex]
Hence, the probability that a person likes the color blue given that they are a woman=0.25%

Answer the following questions using what you've learned from this unit. Write your
responses in the space provided.
1. Factor the polynomial. (2 polnts)
-3x4 - 9x3 + 15x2
2. Use the grouping method to factor the polynomial below completely. (4 points)
10x3 - 35x2 + 6x - 21
Answer: 1. 3x^2(-x^2-3x+5). 2. (2x-7)(5x^2+3)
Step-by-step explanation:
(1) Find the greatest common factor - 3x^2. Simplify as much as possible.
(2) Split 10x^3 - 35x^2 and 6x-21 into two separate groups. Factor each group separately to get 5x^2(2x-7) and 3(2x-7). The numbers in the parentheses should be the same for each group - (2x-7). Take the numbers outside of the parentheses and put them together to get (5x^2+3). Your final answer will be (2x-7)(5x^2+3).
1. The required factor of the polynomial is
(-3x²)(x²+3x-5).
2. The required factor of the polynomial using grouping method, the answer is (5x²+3)(2x-7).
What is a polynomial?"A polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables."
What is factorization of a polynomial?"The factorization of polynomials or polynomial factorization expresses a polynomial with coefficients in a given field or in the integers as the product of irreducible factors with coefficients in the same domain.
There are six different methods to factorizing polynomials. One of those methods is factorization of a polynomial by grouping method."
1. The given polynomial is
[tex]-3x^{4} - 9x^{3} + 15x^{2} \\= - 3x^{2}(x^{2}+3x-5)\\[/tex]
Therefore, by factorizing the given polynomial, we get:
[tex]- 3x^{2}(x^{2}+3x-5)[/tex].
2. The given polynomial is
[tex]10x^{3}-35x^{2} +6x-21[/tex]
We need to factorize it using grouping method.
Therefore,
[tex]10x^{3}-35x^{2} +6x-21\\= 5x^{2}(2x-7)+3(2x-7)\\= (5x^{2} +3)(2x-7)[/tex]
Hence,
1. The required factor of the polynomial is
(-3x²)(x²+3x-5).
2. The required factor of the polynomial using grouping method, the answer is (5x²+3)(2x-7).

Answer:
Both expression equals 5 when substituting 2 for x, because the expressions are equivalent.
Step-by-step explanation:
Given the expressions:
(1/2)x + 4
x + 6 - (1/2)x - 2
Substituting 2 for x in the equation :
(1/2)x + 4
x = 5
(1/2)2 + 4
2/2 + 4
1 + 4
= 5
x + 6 - (1/2)x - 2
Substituting 2 for x
2 + 6 - (1/2)2 - 2
8 - 2/2 - 2
8 - 1 - 2
= 5

If g(x) is the inverse of f(x) and f (x) = 4 x + 12, what is g(x)?
Answer:
[tex]let \: the \: inverse \: of \: f(x) \: be \: m \\ m = {f(x)}^{ - 1} \\ m = {(4x + 12)}^{ - 1} \\ m = \frac{1}{(4x + 12)} \\ m(4x + 12) = 1 \\ 4x = \frac{1}{m} - 12 \\ x = \frac{1}{4m} - 3 \\ therefore \\ g(x) = \frac{1}{4x} - 3[/tex]
Answer:
g(x) = 1/4 x -3
Step-by-step explanation:
f (x) = 4 x + 12
g(x) = f⁻¹(x)
step 1: re-write as linear equation y = 4x+12
step 2: swap x and y x = 4y + 12
step 3: solve y 4y = x - 12 y = 1/4 x -3
step 4: inverse notation: f⁻¹(x) = 1/4 x - 3 i.e. g(x) = 1/4 x -3

The price of an item has been reduced by 10%. The original price was $21.
Use the ALEKS calculator to find the price of the item now.
Answer:
$18.90
Step-by-step explanation:
Multiply the original price by the percentage
$21 x 10% = $2.10
You then subtract this from the original to get the discounted price
$21 - $2.10 = $18.90
The measures of the angles of a triangle are shown in the figure below. Solve for x.
(4x-6)
73°
57°
Answer:
14°
Step-by-step explanation:
Sum of angles is 180°
57 + 73 + (4x - 6) = 180
130 + 4x - 6 = 180
4x = 180 - 130 + 6
4x = 56

For every 24 lb of body mass, a gorilla
will eat 4 lb of food each day. If a gorilla
eats 40 lb of food in a day, how much
does it weigh?
HELP ME
Answer:
tje gorilla weights 240 lb
Answer: 240 pounds
Work Shown:
(body mass)/(amount eaten) = (body mass)/(amount eaten)
(24 lb body mass)/(4 lb eaten) = (x lb body mass)/(40 lb eaten)
24/4 = x/40
6 = x/40
x/40 = 6
x = 40*6
x = 240
The gorilla has 240 pounds of body mass.
The time period, T, of a simple pendulum is directly proportional to the square root of the length, d, of the pendulum.
When d=6, T=5
Find the value of T when d=3
Input note: give your answer correct to 2 decimal place.
Answer:
[tex]T = 3.54[/tex]
Step-by-step explanation:
Given
Direct Variation of T to [tex]\sqrt d[/tex]
[tex]d =6;\ when\ T = 5[/tex]
Required
Determine T when d = 3
The variation can be represented as:
[tex]T\ \alpha\ \sqrt d[/tex]
Convert to equation
[tex]T = k\sqrt d[/tex]
[tex]d =6;\ when\ T = 5[/tex]; so we have:
[tex]5 = k * \sqrt 6[/tex]
Make k the subject:
[tex]k = \frac{5}{\sqrt 6}[/tex]
To solve for T when d = 3.
Substitute 3 for d and [tex]k = \frac{5}{\sqrt 6}[/tex] in [tex]T = k\sqrt d[/tex]
[tex]T = \frac{5}{\sqrt 6} * \sqrt{3}[/tex]
[tex]T = \frac{5\sqrt{3}}{\sqrt 6}[/tex]
[tex]T = \frac{5 * 1.7321}{2.4495}[/tex]
[tex]T = \frac{8.6605}{2.4495}[/tex]
[tex]T = 3.5356[/tex]
[tex]T = 3.54[/tex] -- approximated

What is the length of Line segment M N? 58 cm 75 cm 88 cm 116 cm
Answer:
A
Step-by-step explanation:
Edge
The measure of MN is equal to 58cm, the correct option is A.
What is a Triangle?A triangle is a polygon with three sides, vertices and angle.
Triangle A B C is cut by line segment M N.
such that,
A M = M B = 88 centimeter
CN =NB = 75 centimeter
AC = 116 centimeter
If a line segment joins the mid-points of two sides of a triangle, then the line segment is parallel to the third side of the triangle and the measure is equal to half of its length.
MN = (1/2) AC
MN = (1/2) * 116
