[tex]\displaystyle y = -3x + 9[/tex]
Step-by-step explanation:
First, find the rate of change of the line:
[tex]\displaystyle \frac{-y_1 + y_2}{-x_1 + x_2} = m \\ \\ \frac{-6 + 3}{-1 + 2} = m \hookrightarrow \frac{-3}{1} = m \\ \\ \boxed{-3 = m}[/tex]
_______________________________________________
Now plug all the information into the Slope-Intercept Formula. It does not matter which ordered pair is chosen:
[tex]\displaystyle 3 = -3[2] + b \hookrightarrow 3 = -6 + b; 9 = b \\ \\ \boxed{\boxed{y = -3x + 9}} \\ \\ OR \\ \\ 6 = -3[1] + b \hookrightarrow 6 = -3 + b; 9 = b \\ \\ \boxed{\boxed{y = -3x + 9}}[/tex]

A cylinder has a height of 23m and a volume of 18488m^3 what is the radius of the cylinder. Round your answer to the nearest whole number
Answers
Answer:
Radius=16m
Step-by-step explanation:
It is given that A cylinder has a height of 23 m and a volume of 18,488 m³. then, the volume of the cylinder is given as:
Substituting the given values, we get
≈
Thus, the radius of the cylinder will be 16m.
Answer:
Radius = 16m
Step-by-step explanation:
It is given that A cylinder has a height of 23 m and a volume of 18,488 m³. then, the volume of the cylinder is given as:
[tex]v=\pi r^{2} h[/tex]Substituting the given values, we get
[tex]18488=3.14(r^{2} )(23)[/tex]
[tex]18488=72.22(r^{2} )[/tex]
[tex]r^{2} =255.99[/tex]
[tex]r=\sqrt{255.99}[/tex]
[tex]r=15.99[/tex]
[tex]r=16m[/tex]
Thus, the radius of the cylinder will be 16m.

Step-by-step explanation:
Part A
Area of a rectangle = length x width
Garden area = 7 3/4 x 2 2/3
= 31/4 x 8/3
= 62/3
= 20 2/3 square feet
Part B
5/8 of the area = 62/3 * 5/8
= 31*5 / 3*12
= 155 / 36
= 4 11/36
The question asks to do so without calculation - the only way is that because the length is approximately 8 feet, section off 5 feet along the length will give an area approximately 5/8 of the total area.

The cost of a concert ticket last week was $60.00. This week a concert ticket is $75.00. What is the percent increase of the ticket from last week to this week
Answers
Answer: The increase was by 25 %. (125% change)
Step-by-step explanation: 75-60 is 15, so the difference was that it increased by $15. 15 divided by 60, is .25, or 25%. Meaning it increased by 25%, or there was an 125% change.
Determine whether the underlined number describes a population parameter or a sample statistic. Explain your reasoning. Sixty-five of the 93 passengers aboard an airship survived an explosion Choose the correct statement below.
A. The number is a sample statistic because it is a numerical description of all of the passengers that survived.
B. The number is a population parameter because it is a numerical description of all of the passengers that survived.
C. The number is a population parameter because it describes the people in the airship, which is a subset of all people.
D. The number is a sample statistic because it describes the people in the airship, which is a subset of all people.
Answers
Answer: A. The number is a sample statistic because it is a numerical description of all of the passengers that survived.
Step-by-step explanation:
A population is simply similar items or events that a researcher or an experimenter is interested and wants to carry out an experiment on.
A statistic is simply referred to as the piece of information gotten from the population while a sample statistic is the piece of statistical information which a researcher will be able to get from the statistic.
In this scenario, the number is a sample statistic because it is a numerical description of all of the passengers that survived.

A ternary string is an ordered string of characters which consists of digits (0,1, or 2). For example, the ternary string 2122010 consists of exactly 2 zero's, 2 one's and 3 two's; another ternary string meeting these conditions is 0021221. How many ternary strings are there with exactly 4 zero's, 3 one's and 6 two's?
Answers
The number of ternary strings is an illustration of combination
There are 6227020800 ternary strings with exactly 4 zero's, 3 one's and 6 two's
How to determine the number of stringsAssume the zero's, one's and the two's can take any position in the string
For a ternary string of exactly 4 zero's, 3 one's and 6 two's, the number of characters in the string is 13.
The first 4 zeros can take any of the 13, 12, 11 and 10th positions
The next 3 ones can take any of the 9, 8 and 7th positions
The remaining 6 twos can take any 6! positions
So, the number of strings is:
Strings = 13* 12 * 11 * 10 * 9 * 8 * 7 * 6!
Evaluate the products
Strings = 6227020800
Hence, there are 6227020800 ternary strings with exactly 4 zero's, 3 one's and 6 two's

It is known that 10% of the 9-year old children in a town have three siblings. Fifteen 9-year old children are selected at random. Find the probability that more than 3 of these selected children have three siblings (round off to second decimal place).
Answers
Using the binomial distribution, it is found that there is a 0.0555 = 5.55% probability that more than 3 of these selected children have three siblings.
What is the binomial distribution formula?The formula is:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.In this problem, for the parameters, we consider that:
10% of the 9-year old children in a town have three siblings, hence p = 0.1.Fifteen 9-year old children are selected at random, hence n = 15.The probability that more than 3 of these selected children have three siblings is given by:
[tex]P(X > 3) = 1 - P(X \leq 3)[/tex]
In which:
[tex]P(X \leq 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)[/tex]
Then:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{15,0}.(0.1)^{0}.(0.9)^{15} = 0.2059[/tex]
[tex]P(X = 1) = C_{15,1}.(0.1)^{1}.(0.9)^{14} = 0.3432[/tex]
[tex]P(X = 2) = C_{15,2}.(0.1)^{2}.(0.9)^{13} = 0.2669[/tex]
[tex]P(X = 3) = C_{15,3}.(0.1)^{3}.(0.9)^{12} = 0.1285[/tex]
[tex]P(X \leq 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) = 0.2059 + 0.3432 + 0.2669 + 0.1285 = 0.9445[/tex]
P(X > 3) = 1 - 0.9445 = 0.0555
0.0555 = 5.55% probability that more than 3 of these selected children have three siblings.
