Please if you know the answer tell me it and the steps also thank you.
Step-by-step explanation: Well to begin, you take 15$ and multiply it by 4, since he wants to buy 4 of those tickets, which is 60$. Then, take the 10$ and multiply it by 2 since he wants 2 of those tickets, which is 20$, you then apply 10% to 60 and 20 by taking 10 percent of 60, then adding it to 60 once have that, which is 66, you take the 3% and find 3% of 66, then add the answer of that to 66, which is 67.98$, you then do the same thing to the 20$.

A random variable is a variable that can take on different values depending on the outcome of a random event. In this case, the random variable X represents the number of calls per hour to a call center in the last month.
a. The missing value in the table is the number of calls per hour for the probability 0.03. From the table, we see that the number of calls per hour is 7.
b. The mean, also known as the expected value, is a measure of the center of the probability distribution. It is calculated by taking the sum of the product of each possible value of X and its corresponding probability. In mathematical terms, the mean of X is given by:
E(X) = 1 * P(1) + 2 * P(2) + 4 * P(4) + 5 * P(5) + 6 * P(6) + 7 * P(7)
E(X) = 0.01 + 0.2 + 1.04 + 1.65 + 1.08 + 0.21 = 4.18
So, the mean number of calls per hour to the call center in the last month is 4.18.
c. The variance of X is a measure of the spread of the probability distribution. It is calculated by taking the sum of the squared differences between each possible value of X and the mean, multiplied by the corresponding probability. In mathematical terms, the variance of X is given by:
Var(X) = (1 - 4.18)² * P(1) + (2 - 4.18)² * P(2) + (4 - 4.18)² * P(4) + (5 - 4.18)² * P(5) + (6 - 4.18)² * P(6) + (7 - 4.18)² * P(7)
Var(X) = 3.23
The standard deviation is the square root of the variance, and it is also a measure of the spread of the probability distribution. In mathematical terms, the standard deviation of X is given by:
=> SD(X) = √(Var(X)) = √(3.23) = 1.80
d. Interpretation:
The mean of 4.18 calls per hour represents the average number of calls to the call center in the last month.
The standard deviation of 1.80 indicates that the number of calls per hour deviates from the mean by approximately 1.80 calls on average.
This means that about 68% of the time, the number of calls per hour will be between 2.38 (4.18 - 1.80) and 6.08 (4.18 + 1.80).

Given two triangles.
Also given that, the scale drawings given are the reduction of the figure.
Most probably, the second triangle must be formed after a reduction with a scale factor of k.
Let k be the required scale factor.
The value of k can be found by taking the ratio of the corresponding sides.
k = 5.2 / 10.4

Simplify.
−6i−44−−−−√
Enter your answer, in simplest radical form, in the box.
Expressions that have the square root sign are said to be radicals.
The simplified form of \(-6i\sqrt{-44}\) is \(12\sqrt{11}\)
The expression is given as:
\(-6i\sqrt{-44}\)
Start by splitting the expression
\(-6i\sqrt{-44} = -6 \times i \times \sqrt{-44}\)
Factorize -44
\(-6i\sqrt{-44} = -6 \times i \times \sqrt{-1} \times \sqrt{44}\)
In complex numbers;
\(i = \sqrt{-1\)
So, we have:
\(-6i\sqrt{-44} = -6 \times \sqrt{-1} \times \sqrt{-1} \times \sqrt{44}\)
Express \(\sqrt{-1} \times \sqrt{-1}\) as \(-1\)
\(-6i\sqrt{-44} = -6 \times -1 \times \sqrt{44}\)
\(-6i\sqrt{-44} = 6 \times \sqrt{44}\)
Express 44 as 4 x 11
\(-6i\sqrt{-44} = 6 \times \sqrt{4} \times \sqrt{11}\)
Express \(\sqrt 4\) as \(2\)
\(-6i\sqrt{-44} = 6 \times 2 \times \sqrt{11}\)
\(-6i\sqrt{-44} = 12 \times \sqrt{11}\)
\(-6i\sqrt{-44} = 12\sqrt{11}\)
Hence, the simplified expression is: \(12\sqrt{11}\)

Solve for the unknown. q- 5/6=1 5/6
Answer:
q=8/3
Step-by-step explanation:
First, add 5/6 to both sides to get rid of -5/6 to get q=16/6 then simplify to q=8/3.
Answer:
\(q=2\frac{2}{3}\)
Step-by-step explanation:
The given equation consists of a fraction and a mixed number.
First, convert the mixed number into an improper fraction by multiplying the whole number by the denominator of the fraction, adding this to the numerator of the fraction, and placing the answer over the denominator:
\(q-\dfrac{5}{6}=1 \frac{5}{6}\)
\(q-\dfrac{5}{6}=\dfrac{1 \cdot 6+5}{6}\)
\(q-\dfrac{5}{6}=\dfrac{11}{6}\)
Now, add 5/6 to both sides of the equation to isolate q:
\(q-\dfrac{5}{6}+\dfrac{5}{6}=\dfrac{11}{6}+\dfrac{5}{6}\)
\(q=\dfrac{11}{6}+\dfrac{5}{6}\)
As the fractions have the same denominator, we can carry out the addition by simply adding the numerators:
\(q=\dfrac{11+5}{6}\)
\(q=\dfrac{16}{6}\)
Reduce the improper fraction to its simplest form by dividing the numerator and denominator by the greatest common factor (GCF).
The GCF of 16 and 6 is 2, therefore:
\(q=\dfrac{16\div 2}{6 \div 2}\)
\(q=\dfrac{8}{3}\)
Finally, convert the improper fraction into a mixed number by dividing the numerator by the denominator:
\(q=2 \; \textsf{remainder}\;2\)
The mixed number answer is the whole number and the remainder divided by the denominator:
\(q=2\frac{2}{3}\)

Eliminate the parameter in the equations x = t^1/3 and y = t – 4. How can the rectangular equation be described?
This is the rectangular equation described by the parameter equation x = t1/3 and y = t – 4.
Elimination of the parameter means to rewrite the equations in terms of only x and y. To do this, substitute t from one equation into the other equation. Here, the two equations are:x = t1/3 and y = t – 4Substitute t from the first equation into the second equation:y = (x^3) – 4Now the equation is in terms of x and y only.
This is the rectangular equation described by the parameter equation x = t1/3 and y = t – 4.The rectangular equation, y = (x^3) – 4 can be plotted on a graph. It is a cubic equation. The graph will look like a curve that passes through the point (0, -4) and continues to move towards infinity. The graph will be symmetric to the origin because the equation involves an odd power of x.
If the equation involved an even power of x, the graph would be symmetric to the y-axis. The graph will never touch the x-axis or y-axis, it will only approach them.In conclusion, the rectangular equation y = (x^3) – 4 is derived from the two parameter equations, x = t1/3 and y = t – 4. The graph of this equation is a cubic curve that is symmetric to the origin. The curve passes through (0, -4) and approaches the x and y-axes but never touches them.

The solution of the equation 3(p - 5) = 5p -27 is
A) p = 6
B) p = 5
C) p = 4
D) p = 3
Answer:
A) p = 6
Step-by-step explanation:
Given equation:
3(p - 5) = 5p -27
Apply the Distributive Property of Multiplication over subtraction law:
⇒ 3 · p - 3 · 5 = 5p - 27
⇒ 3p - 15 = 5p - 27
Add 27 to both sides:
⇒ 3p - 15 + 27 = 5p - 27 + 27
⇒ 3p + 12 = 5p
Subtract 3p from both sides:
⇒ 3p - 3p + 12 = 5p - 3p
⇒ 12 = 2p
⇒ 2p = 12
Divide both sides by 2:
⇒ 2p ÷ 2 = 12 ÷ 2
⇒ p = 6
Manny grows vegetables in a community garden.
His part of the garden is a rectangular area that is 6 yards long and 5 1/3 yards wide. What is the area of Manny’s garden? Be sure to include units in your answer.
Answer:
32 yards (squared)
Step-by-step explanation:
Length x width = area (LxW=A)
Step 1:
Length = 6 yards
Width = 5 1/3 yards
Step 2:
Multiply 6 x 5 1/3 because 6 is the length, 5 1/3 is the width, and LxW=A.
6 x 5 1/3 = 32 yards (squared)

The sum of the fractions 2 / 13 + 4 / 13 is 6 / 13
What are fractions:Fractions are number expressed as a quotient, in which a numerator is divided by a denominator. A fraction is improper if the numerator(upper value) is bigger than the denominator(lower value). A fraction is proper if the denominator is bigger than the numerator.
Therefore, let's find the sum of 2 / 13 and 4 / 13.
2 / 13 is a proper fraction
4 / 13 is a proper fraction
2 / 13 + 4 / 13
The least common denominator is 13. Therefore,
2 / 13 + 4 / 13 = 2 + 4 / 13 = 6 / 13

Answer:
1.4
Step-by-step explanation:
we have to subtract the length of the first hike from the second to see how much longer the second hike was.
6.1 - 4.7 = 1.4
The second hike was 1.4 miles longer.
What is Subtraction?Subtraction can be done for any numbers or algebraic expressions. It is the process of taking out certain value from a given amount of number.
The process of subtraction can also be termed as finding difference.
Given that,
Tameron took two hikes this week.
Distance that Tameron hiked in first hike = 4.7 miles
Distance that Tameron hiked in second hike = 6.1 miles
We have to find that how much longer is the second hike.

Given:
m∠SPQ = 113 degrees
Let's find the measure of angle RQS, m∠RQS.
By applying the angle-arc relationship, we have:
m∠SPQ = measure of arc SQ = 113 degrees.
Since RQ is the diameter, measure of arc RQ = 180 degrees.
Now, let's find the measure of arc RS:
measure of arc RS = 360 - arc SQ - arc RQ
measure of arc RS = 360 - 113 - 180 = 67 degrees.
To find the m∠RQS, apply angle-arc relationship:
\(\begin{gathered} m∠RQS=\frac{1}{2}arcRS \\ \\ m∠RQS=\frac{1}{2}*67 \\ \\ m∠RQS=33.5^o \end{gathered}\)Therefore, the measure of angle RQS is 33.5 degrees.
ANSWER:
m∠RQS = 33.5°
A realtor is decorating some homes for sale, putting a certain number of decorative pillows on each twin bed and a certain number on
each queen bed. In one house, she decorated 1 twin bed and 2 queen beds and used a total of 27 pillows. At another house, she used
37 pillows to spruce up 3 twin beds and 2 queen beds. How many decorative pillows did the realtor arrange on each bed?
Answer:
Each of the twin beds: 5 decorative pillows
Each of the queen beds: 11 decorative pillows
Step-by-step explanation:
Let the number of pillows used for each twin bed be x
Let the number of pillows used for each queen bed be y
she decorated 1 twin bed and 2 queen beds and used a total of 27 pillows. Thus;
x + 2y = 27 - - - (eq 1)
Also, she used
37 pillows to spruce up 3 twin beds and 2 queen beds. Thus;
3x + 2y = 37 - - - (eq 2)
From eq 1, x = 27 - 2y
Thus;
3(27 - 2y) + 2y = 37
81 - 6y + 2y = 37
81 - 4y = 37
4y = 81 - 37
4y = 44
y = 44/4
y = 11
x = 27 - 2(11)
x = 27 - 22
x = 5
Thus, she used 5 decorative pillows for each of the twin beds and 11 decorative pillows for each of the queen bed
