Lynne is rolling a six-sided number cube repeatedly. Her goal is to roll an even number 23 times. How many times should Lynne expect to have to roll the number cube to result in an even number 23 times? Enter your answer in the box to correctly complete the statement
Answers
Using the binomial distribution, it is found that she should expect to roll the number cube 46 times.
What is the binomial probability distribution?It is the probability of exactly x successes on n repeated trials, with p probability of a success on each trial.
The expected number of trials until q successes is:
[tex]E_s(X) = \frac{q}{p}[/tex]
In this problem:
She wants 23 successes, hence q = 23.Of the six numbers on the cube, three are even, hence the probability of a success on a trial is of p = 3/6 = 0.5.Then:
[tex]E_s(X) = \frac{23}{0.5} = 46[/tex]
She should expect to roll the number cube 46 times.

Which angle is coterminal with a 120° angle?
A. An angle measuring 300°
B. An angle measuring-120°
C. An angle measuring 470°
D. An angle measuring 480°
Answers
An angle measuring 480° is coterminal with a 120° angle.
Coterminal anglesThis classification represents angles that do not present the same value, but they present vertices and sides are identical. Also, if the angles are coterminal, then their sines, cosines and tangents are equal.
A coterminal angle can be found from the formula β = α ± 360 * w, where w is a positive integer.
Thus,
For w=1 and α=120°β = 120 ± 360 * 1
β = 120 ± 360
Then, β can be 120+360=480° or 120-360= -240°
For w=2 and α=120°β = 120 ± 360 * 2
β = 120 ± 720
Then, β can be 120+720=840° or 120-720= -600°
Therefore, the answer to this question is option D.

What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
We are given that;
For daises= $6.99
For soil potting =$3.98
For ceramic pot= $7.95
Now,
The correct answer is C) $20.00 - $18.92 = $1.08.
To find the amount of change Kate receives back, we need to subtract the total cost of her purchases from the amount of money she has. The total cost of her purchases is:
$6.99 + $3.98 + $7.95 = $18.92
Kate has $20.00, so we can find the amount of change she receives back by subtracting the total cost of her purchases from $20.00:
$20.00 - $18.92 = $1.08
Therefore, by algebra answer will be $1.08.

Answers
The length of arc JL is approximately 15.08 units.
We have,
The length of an arc in a circle can be calculated using the formula:
Arc Length = (θ/360) * 2πr
where θ is the central angle in degrees, r is the radius of the circle, and 2π is approximately 6.28.
In this case, we are given the central angle JKL = 144° and the radius JK = 6 units.
Plugging in the values, we have:
Arc Length = (144/360) * 2π * 6
Arc Length ≈ (0.4) * 6.28 * 6
Arc Length ≈ 15.072 units
Rounded to the nearest hundredth,
The length of arc JL is approximately 15.08 units.
Thus,
The length of arc JL is approximately 15.08 units.

Step-by-step explanation:
The dregree is related to the exponent.
Every problem you have 1-5 shows a monomial. A monomial is a sinlge number, or a number multiplied by 1 or more variables.
The degree of a monomial is the sum of the exponents of all the variables of the monomial.
A variable is a letter. In these 5 problems, the variables are a, b, c, x, y, z.
If a variable has no exponent written, then its exponent is 1.
1. 4x²
There is one variable. The exponent on the variable is 2. The degree is 2.
2. 6abc
There are 3 variables, a, b, and c. Each variable has exponent 1 even though we do not write the 1. This expression is the same as 6a^1b^1c^1. Add the exponents: 1 + 1 + 1 = 3. The degree is 3.
3. 2xy
Rewrite, or think of it as, 2x^1y^1. Add the expoenents: 1 + 1 = 2. The degree is 2.
4. a²b²
Add the exponents: 2 + 2 = 4. The degreee is 4.
5. xyz³
Rewrite as or think of it as: x^1y^1z³. The sum of the exponents is 1 + 1 + 3 = 5. The degree is 5.

5x + (- x) - 1 = 11 - 2x , that is
5x - x - 1 = 11 - 2x
4x - 1 = 11 - 2x ( add 2x to both sides )

Mr. Schultz is randomly distributing 15 rulers with centimeter markings and 10 rulers without centimeter markings to his class. What is the probability that the first ruler he hands out will have centimeter markings and the second one does not have the markings?.
Answers
Using it's concept, it is found that there is a 0.25 = 25% probability that the first ruler will have centimeter markings and the second one will not.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem:
For the first ruler, there are 15 with markings out of 25, hence P(A) = 15/25.For the second ruler, there are 10 without markings out of 24, hence P(B|A) = 10/24.Thus, the probability is given by:
[tex]P(A \cap B) = P(A)P(B|A) = \frac{15}{25} \times \frac{10}{24} = 0.25[/tex]
0.25 = 25% probability that the first ruler will have centimeter markings and the second one will not.

There were Math and Science books in one section of a library. Before an addition of 84 Math books, the ratio of Math books to Science books was 3 : 7. How many Science books were there if the eventual ratio of Math books to Science books was 6 : 7?
Answers
Answer:
196 science books
Step-by-step explanation:
Check the attachment.
The total number of sicience books were 196.
What is ratio?Ratio is a term that is used to compare two or more numbers. It is used to indicate how big or small a quantity is when compared to another. In a ratio, two quantities are compared using division.
Let the total numbers of science books be x and maths books be y.
According to the given question.
The intial ratio of maths books to the science books is 3:7.
⇒ [tex]\frac{y}{x} = \frac{3}{7}[/tex] ...(i)
But, after the addition of 84 maths books the ratio gets changed to 6:7.
[tex]\implies \frac{y +84}{x} = \frac{6}{7}[/tex] ...(ii)
Solving the equations i and ii.
From equation i.
[tex]7y = 3x[/tex]
And from equation ii
[tex]7y + 7(84) = 6x[/tex]
Substitute the value of 7y = 3x in the above equation.
[tex]3x + 588 = 6x[/tex]
[tex]\implies 588 = 6x -3x[/tex]
[tex]\implies 3x = 588[/tex]
[tex]\implies x = \frac{588}{3}[/tex]
[tex]\implies x = 196[/tex]
Hence, the total number of sicience books were 196.
