A ball is drawn at random and then replaced, and then a second ball is drawn. Find the probability that the first is black and the second iswhite.
Answer:
[tex]Probability = 0.2470[/tex]
Step-by-step explanation:
Given
[tex]Black = 4[/tex]
[tex]White = 5[/tex]
[tex]Total = 9[/tex] i.e. 5 + 4
Required
Determine [tex]P(Black\ and\ White)[/tex]
In probability;
[tex]P(A\ and\ B) = P(A) * P(B)[/tex]
So:
[tex]P(Black\ and\ White) = P(Black) * P(White)[/tex]
i.e. multiply the probability of selecting black by that of selecting white
[tex]P(Black\ and\ White) = \frac{n(Black)}{Total} * \frac{n(White)}{Total}[/tex]
[tex]P(Black\ and\ White) = \frac{4}{9} * \frac{5}{9}[/tex]
[tex]Probability = \frac{20}{81}[/tex]
[tex]Probability = 0.2470[/tex]
Write a function to convert Celsius to Fahrenheit using F=(9/5)C+32. Find the Fahrenheit value when C=56.7 and when C=−89.2. (The record high and low temperatures ever recorded on Earth.)
If x is the given temperature in Celsius, the function to return the equivalent temperature in Fahrenheit it:
f(x) = 9 / 5 * x + 32
f(x) = 9/5x + 32
f(x) = 9/5 * (x + 32)
f(x) = 9/5c + 32
The value in Fahrenheit at C=56.7 (a record high) is:
?
The value in Fahrenheit at C=−89.2 (a record low) is:
?
Using your function, f(C), to convert Celsius to Fahrenheit, compare the difference at C=20 between the function value and the simpler function: g(C)=2C+30. (In other words, is "double and add 30" a reasonable approximation?)
The difference f(C)−g(C) at C=21 (approximate room temperature) is:
?
The function used to convert Celsius to Fahrenheit is: 5/9(F - 32)
The Fahrenheit value when C = 56.7 is: 134.06
and when C = 89.2, F = -128.56, as found by basic algebra. If x is the given temperature in Celsius, the function used to return the equivalent temperature in Fahrenheit is: f(x) = 9 / 5 * x + 32 (Option A).
What is basic algebra?Numbers, variables, constants, expressions, equations, linear equations, and quadratic equations are all part of the basics of algebra. Additionally, the algebraic expressions contain the basic arithmetic operations of addition, subtraction, multiplication, and division.(1)
Given:
F = 9/5 × (C) + 32
F - 32 = 9/5 × (C)
5/9 × (F-32) = C(2)
For C = 56.7, in the above formula, by basic algebra, we get:
F = 9/5 × (56.7)+32
F = 102.06 + 32
F = 134.06
For C = -89.2, by basic algebra,
we get: F = (9/5) × (-89.2)+32
F = -160.56 + 32
F = -128.56(3)
We are given:
F = 9/5 (C) + 32
If f(x) represents the temperature in Fahrenheit, we get:
f(x) = 9/5 (C) + 32,
which is equivalent to Option A.
Hence, (1) The function used to convert Celsius to Fahrenheit is:
9/5(F-32)
(2) The Fahrenheit value when C = 56.7 is: 134.06 and when C = 89.2, F = -128.56, as found by basic algebra.
(3) If x is the given temperature in Celsius, the function used to return the equivalent temperature in Fahrenheit is: f(x) = 9 / 5 * x + 32 (Option A).

Six more than seven times a number equals 10 times the number -12
Answer:
The equation becomes
[tex]7x+6 = 10x-12[/tex]
Thus, the number = x = 6
Step-by-step explanation:
Let 'x' the number
seven times a number = 7x
Six more than seven times a number = 7x+6
10 times the number -12 = 10x-12
Given that Six more than seven times a number equals 10 times the number -12.
Thus, the equation becomes
[tex]7x+6 = 10x-12[/tex]
We can further solve for x
[tex]7x+6 = 10x-12[/tex]
[tex]6+12 = 10x-7x[/tex]
[tex]18 = 3x[/tex]
[tex]x = 6[/tex]
Thus, the number = x = 6

Dedra polled people at the mall to determine which types of movies
they preferred to watch. She displayed the results in a circle graph.
Of the people polled, 120 preferred to
to watch action movies. Use this information and
the graph to answer these questions.
a) What is the total number of people
Dedra polled?
The total number of people Dedra polled is 400.
Given,
Number of people preferred to watch action movies = 120
We have to find the total number of people Dedra polled:
According to the given circle graph:
Percentage of people preferred to watch action movies = 30%
Now,
The total number of people polled = x
Then,
30% of x ix 120.
So,
x = (120 × 100) / 30
x = 4 × 100
x = 400
Therefore the total number of people Dedra polled is 400.
Lets check the others also:
Comedy: 35%
∴ (400 × 35) / 100 = 4 × 35 = 140
140 people preferred to watch comedy movies.
Drama: 20%
∴ (400 × 20) / 100 = 4 × 20 = 80
80 people preferred to watch drama movies.
Fantasy: 10%
∴ (400 × 10) / 100 = 4 × 10 = 40
40 people preferred to watch fantasy movies.
Horror: 5%
∴ (400 × 5) / 100 = 4 × 5 = 20
20 people preferred to watch horror movies.
The total number of people Dedra polled is 400

The coordinates of points A and B are A (-10,-8) and B (80, 37). Which are the
coordinates of a point that partitions segment AB in a ratio of 4:5?
Given that,
The coordinates of A = (-10,-8)
The coordinates of B = (80,37)
To find,
The coordinates of a point that partitions segment AB in a ratio of 4:5.
Solution,
Let the coordinate of required point is (x,y). We can use section formula to find it as follows :
The section formula is :
[tex](x,y)=(\dfrac{m_2x_1+m_1x_2}{m_1+m_2},\dfrac{m_2y_1+m_1y_2}{m_1+m_2},)[/tex]
We have,
m₁ =4, m₂ = 5, x₁ = -10, x₂ = 80, y₁ = -8, y₂ = 37
Using all the values,
[tex](x,y)=(\dfrac{5(-10)+4(-10)}{4+5},\dfrac{5(-8)+4(37)}{4+5})\\\\=(-10,12)[/tex]
So, the required point in which AB is divided is (-10,12)
