Answers
The probability that the book is nonfiction given that it is hard-covered is 4/11
How to determine the probability?From the complete question, we have:
Total = 20
n(H ∩ N) = 4
n(H) = 11
This means that:
P(H ∩ N) = n(H ∩ N)/Total
So, we have:
P(H ∩ N) = 4/20
The conditional probability is then calculated using:
P(N | H) =4/20 ÷ 11/20
Evaluate
P(N | H) = 4/11
Hence, the probability that the book is nonfiction given that it is hard-covered is 4/11

Which of the following is NOT a rational number?

Answers
Answer:
A rational number is a number that can be expressed as a fraction (the ratio of two integers).
Integer: A whole number that can be positive, negative, or zero.
To calculate if each radical can be expressed as a rational number, convert the decimals into rational numbers, then simplify:
[tex]\sqrt{121}=\sqrt{11^2}=11=\dfrac{11}{1} \quad \leftarrow \textsf{rational}[/tex]
[tex]\sqrt{12.1}=\sqrt{\dfrac{1210}{100}}=\dfrac{\sqrt{1210}}{\sqrt{100}}=\dfrac{\sqrt{121\cdot 10}}{10}=\dfrac{\sqrt{121}\sqrt{10}}{10}=\dfrac{11\sqrt{10}}{10} \leftarrow \textsf{not rational}[/tex]
[tex]\sqrt{1.21}=\sqrt{\dfrac{121}{100}}=\dfrac{\sqrt{121}}{\sqrt{100}}=\dfrac{\sqrt{11^2}}{\sqrt{10^2}}=\dfrac{11}{10} \leftarrow \textsf{rational}[/tex]
[tex]\sqrt{0.0121}=\sqrt{\dfrac{121}{10000}}=\dfrac{\sqrt{121}}{\sqrt{10000}}=\dfrac{\sqrt{11^2}}{\sqrt{100^2}}=\dfrac{11}{100} \leftarrow \textsf{rational}[/tex]

How many ways k things out of m different things (m ≥ k) can be chosen if order of the chosen things doesn't matter?We can use combinations for this case,
Total number of distinguishable things is m.
Out of those m things, k things are to be chosen such that their order doesn't matter.
This can be done in total of
[tex]^mC_k = \dfrac{m!}{k! \times (m-k)!}[/tex] ways.
If the order matters, then each of those choice of k distinct items would be permuted k! times.
So, total number of choices in that case would be:
[tex]^mP_k = k! \times ^mC_k = k! \times \dfrac{m!}{k! \times (m-k)!} = \dfrac{m!}{ (m-k)!}\\\\^mP_k = \dfrac{m!}{ (m-k)!}[/tex]
This is called permutation of k items chosen out of m items (all distinct).

Answers
Answer:

Step-by-step explanation:
The test score of the student who joined the class will be;
⇒ 55
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The mean test score of 12 students = 42
And, A student joins the class and the mean becomes 43.
Now,
Total score for 12 students is,
⇒ x / 12 = 42
⇒ x = 42 × 12
⇒ x = 504
Here, A student joins the class and the mean becomes 43.
Let the student who join = y
So, We get;
⇒ (504 + y) / 13 = 43
⇒ 504 + y = 43× 13
⇒ 504 + y = 559
⇒ y = 559 - 504
⇒ y = 55

the measure of one interior angle of a rhombus is [tex]79^{\circ}[/tex] . what are the measures of the other three interior angles?
Answers
Step-by-step explanation:
a rhombus is a parallelogram with 4 identical sides.
it has therefore two pairs of equal angles.
as any quadrilateral the sum of all interior angles is 360°.
(and yes, as add-on, the diagonals bisect each other at right angles).
so, one interior angle is 79°.
that means it has a twin that is also 79°.
together they have 79×2 = 158°.
that leaves
360 - 158 = 202°
for the other 2 angles (they must be equal too).
so, each of them has
202/2 = 101°
so, the other 3 angles are
79°, 101°, 101°

using technology, how many walkways must be shoveled to result in equal billing from both companies?
Answers
The number of walkways that must be shoveled to result in equal billing from both companies is 10
Calculating costFrom the question, we are to determine how many walkways must be shoveled to result in equal billing from both companies
Let the number of walkways be x
From the given information,
Bobs snowplow business charges 300$ per season plus 10$ for each walkway shoveled
∴ If x walkways are shoveled
the billing will be $300 + $10x
For Mikes snow removal
Mikes snow removal charges 250$ per season plus 15$ per walkway
∴ If x walkways are shoveled
the billing will be $250 + $15x
Now, we are to determine the value of x for which the billings from both companies will be equal,
That is,
$300 + $10x = $250 + $15x
$15x - $10x = $300 - $250
$5x = $50
x = $50 / $5
x = 10
Hence, the number of walkways that must be shoveled to result in equal billing from both companies is 10.

Someone is thinking of two numbers that are natural, and one is bigger than the other one by 10, if you multiply those two numbers you get 375 what are those two numbers.
Answers
Answer:
So the two numbers are {15, 25}.
Step-by-step explanation:
Simultaneous Equations:
xy = 375
x = y + 10
Subsitute the Second One into the First:
(y + 10)y = 375
y^2 + 10y - 375 = 0
y = 15 [and not -25 (natural numbers are not negative)]
Solve for x by Substituing y in the Second Equation:
x = 15 + 10
x = 25
Solution:
So the two numbers are {15, 25}.
Answer:
15 and 25
Step-by-step explanation:
The given relations between the two numbers allow you to write a system of equations. Algebraic solution of the system involves the solution of a quadratic equation. The numbers are "natural numbers", so are both positive integers.
__
setupLet x and y represent the smaller and larger of the two numbers, respectively. The given relations are ...
y = x +10 . . . . . . the larger is 10 more than the smaller
xy = 375 . . . . . . their product is 375
solutionSubstituting for y in the second equation, we have ...
x(x +10) = 375
Adding (10/2)² will complete the square.
x² +10x +25 = 375 +25 . . . . add 25
(x +5)² = 400 . . . . . . . . . . . write as a square
x +5 = √400 = 20 . . . . . . positive square root
x = 20 -5 = 15
y = x +10 = 25
Those two numbers are 15 and 25.
__
The attachment shows a graphical solution of the equations.
_____
Additional comment
Your number sense tells you that both numbers end in 5. Their geometric mean is √375 ≈ 19.4, so the first numbers that deserve consideration are numbers ending in 5 that are either side of this value: 15 and 25.
You can also consider their arithmetic mean. If that is represented by z, then we have (z-5)(z+5)=375 ⇒ z²-25=375 ⇒ z²=400 ⇒ z=20, and the two numbers are 20±5.

Answers
The value of x is 6.
What are complementary?Complementary angles are angles that sum up to 90°.
Analysis:
For angles A and B, to be complementary, the sine of angle A must be equal to the cosine of angle B.
sin A = cos B
5X+9 = 3x+21
5x - 3x = 21 - 9
2x = 12
x = 6

Answers
Answer:
a. $0.47 per ounce
b. $0.36 per ounce
c. the gallon size costs less per ounce
Step-by-step explanation:
A unit rate is a rate that is expressed with one unit in the denominator. That is, it is <some amount> per unit. The <some amount> value will generally depend on what unit is chosen. This problem suggests the desired unit is 1 oz of paint.
__
a.Unit cost for a quart:
ratio = cost/ounces = $14.99/(32 oz) ≈ $0.468/oz ≈ $0.47/oz
__
b.Unit cost for a gallon:
ratio = cost/ounces = $45.99/(120 oz) ≈ $0.359/oz ≈ $0.36/oz
__
c.The cost per ounce is less for the gallon size. If at least 3 quarts of paint is needed, then buying it in the gallon size will cost less.
If less than 3 quarts are needed, then a gallon container will cost more than is necessary for the paint required. The "better deal" depends on the amount of paint required.
