The probability that a tutor will see 0, 1, 2, 3, or 4 students
Answers
For the given probability distribution, the missing value is 5/17.
What is probability distribution?A probability distribution is a mathematical function used in probability theory and statistics that estimates the likelihood that various possible outcomes of an experiment will occur. In terms of its sample space and event probability, it is a mathematical description of a random phenomena.
For the given distribution,
Let the missing value be x
we know that sum of probabilities = 1
⇒ 0 + 0 + 7/17 + x + 5/17 = 1
⇒ 12 / 17 + x = 1
⇒ x = 1 - 12/17
⇒ x = 5 / 17

10. The value of the 8th term is 78.The sequence is increasing by 10 at each step.Explicit equation: y = 10x - 2Recursive: now = previous term + 10Find the 9th term.Explanation:
Answers
We have the explicit equatiion:
[tex]\text{ y = 10x - 2}[/tex]The 8th term is 78
y = 10 * 8 - 2
y = 80 - 2
We replaced x by 8
Therefore, for finding the 9th term, we calculate the value this way:
y = 10 * 9 - 2
y = 90 - 2
y = 88
The 9th term of the series is 88

She spent a total of $21 dollars.
The soda cost $3
Then, she bought 7 candy bars for x dollars
We set x because we don't know the price
3 + 7x = 21
Solve the equation for x
Subtract both sides by 3
3-3 + 7x = 21 -3

A new social media site is increasing its user base by approximately 6% per month.Ir the site currently has 21,740 users, what will the approximate user base be 8 months from now?
Answers
Data
• Increase: 6% per month
,• Current users: 21,740
,• Users after 8 months: ?
Procedure
As we are increasing 6%, we have to multiply the original quantity, which represents the 100%, times 100% plus the increase (6%). However, this must be done in decimals:
[tex]\frac{100\%+6\%}{100\%}=\frac{106\%}{100\%}=1.06[/tex]Then, for the first month the user base will be:
[tex]21,740\times1.06=23,044.4[/tex]Then, for the second month the user base will be:
[tex]23,044.4\times1.06=24,427.06[/tex]The third month would be:
[tex]24,427.06\times1.06=25,892.70[/tex]We could do this for eight months or we can take a shortcut:
[tex]U=U_0\times i^n[/tex]where U represents the user, U0 is the initial users, i is the increase rate, and n is the number of months.
Replacing the data we have we get:
[tex]U=21,740\times1.06^8[/tex][tex]U=34,650.26[/tex]Answer: 34,650.26 users after 8 months with a 6% increase per month.

Which of the following ratios does NOT represent a proportional relationship?
Answers
ANSWER
D 3/4 = 8/6
EXPLANATION
For the ratios to be proportional, the fraction on the left hand side must be equivalent to the one on the right hand side.
So, for each of them, we will check if the values are the same.
a) 3/4 = 6/8
Simplifying 6/8 by dividing numerator and denominator by 2 yields:
3/4 = 3/4
The ratio is proportional.
b) 3/6 = 4/8
Simplifying both sides yields:
1/2 = 1/2
The ratio is proportional.
c) 4/3 = 8/6
Simplifying 8/6 by dividing numerator and denominator by 2 yields:
4/3 = 4/3
The ratio is proportional.
d) 3/4 = 8/6
Simplifying 8/6 by dividing numerator and denominator by 2 yields:
3/4 = 4/3
Because the two fractions are not equal, the ratio is not proportional.

What are two ways you can find 17-8? Explain.
Answers
The two ways to find solution of the expression (17-8) are by direct arithmetic method and indirect simplification method.
In arithmetic method, the first step is to determine whether the numbers are rational or irrational, so as to simplify the solution process. If numbers are rational, then they are checked for the sign determining their position on number line and then the calculations are performed. Here, 17 is positive rational number and -8 is negative rational number. Hence, 17-8 is equalized to 9. In indirect simplification method, the numbers to be subtracted are broken down to simpler terms which can be easily subtracted and reduced to get the answer. In the subtraction of 17-8, we break 8 in the form of (7+1). Then the expression becomes 17 - (7+1). Now, this expression can easily be solved to get the answer. Therefore, 17 - (7+1) = 10 - 1 = 9.

What is segment?
In mathematics, the line segment is one of the part of the straight line. It has two endpoints which can be used to calculate the length of the respective segment. It is measured in different units called as meter, centimeter, etc.
According to the question, the given data for the line segment is as follows:
DD' = 58.4 cm; EE' = 58.4 cm; FF' = 58.4 cm
All three segments are equal in length.
In this, the ΔDEF and ΔD'E'F' are equal from angle as well as length sides. And the relationship between two triangles and their vertex state that they are forming two congruent Polygon shapes as well as generating a segment between them. Thus, if there is congruence among the pentagons, it will exist between the formed triangles.
Therefore, it is observed about the segments that connect corresponding vertices that the two triangles are congruent and its corresponding angle pair is congruent. also the two corresponding side pairs are also congruent.

Okay, here we have this:
Considering the provided figure, we are going to calculate the requested surface area, so we obtain the following:
Then we will substitute in the following formula:
Surface Area of Triangular Prism=(√3a^2)/2+3(a+h)
Replacing:
Surface Area of Triangular Prism=(√3*8^2)/2+3(8+6)
Surface Area of Triangular Prism=(√3*64)/2+3(14)
Surface Area of Triangular Prism=(√3*64)/2+42
Surface Area of Triangular Prism=(√3*32)+42
Surface Area of Triangular Prism=32√3+42

Step 1: What is Sam's rate as stated?
Answers
The Sam's rate is 10.35 miles per hours.
What is miles per hour?
In mathematics, miles per hour is the unit for the speed measurement. It is used for the calculation of the speed of the train or people or any another objects. It can be calculated by dividing the distance with time.
According to the question, the given data states that the Sam ran 63,756 feet in 70 minutes.
Distance = 63,756 feet and Time = 70 minutes
And the given conversion is: 5280 feet = 1 miles
Therefore, Sam's rate or speed in miles per hour is as written below:
Speed = Distance/Time
Speed = (63,756/70) x (1/5280) x 60 = 10.35 miles per hours
