Marshal has the following data:
18
3
18
t
18
If the mean of the above data is 15, which number could t be?
t has a value of 18.
What is Mean?In statistics, in addition to the mode and median, the mean is one of the measures of central tendency. Simply put, the mean is the average of the values in the given set. It indicates that values in a particular data set are distributed equally. The three most frequently employed measures of central tendency are the mean, median, and mode. The total values provided in a datasheet must be added, and the sum must be divided by the total number of values in order to determine the mean. When all the values are organized in ascending order, the Median is the median value of the given data. While the number in the list that is repeated a maximum of times is the mode.
As per the given data:
Mean of 18, 3, 18, t, 18 is 15
Mean = (Sum of all observations)/(Total number of observation)
Mean = (18 + 3 + 18 + t + 18)/5
15 = (18 + 3 + 18 + t + 18)/5
75 = 57 + t
t = 18
The value of t is 18.

Step-by-step explanation:
20. Which set of parametric equations over the interval 0 ≤ t ≤ 1 defines a line segment with initial point (–5, 3) and terminal point (1, –6)?
x(t) = –5 + t; y(t) = 3 – 6t
x(t) = –5 + 3t; y(t) = 1 – 6t
x(t) = –5 + 6t; y(t) = 3 – 9t
x(t) = –5 + 8t; y(t) = 1 – 7t
Given:
Initial point = (–5, 3)
Terminal point = (1, –6)
To find:
The set of parametric equations over the interval 0 ≤ t ≤ 1.
Solution:
The interval is 0 ≤ t ≤ 1, initial point is (–5, 3) and terminal point is (1, –6). It means,
[tex]x(0)=-5,y(0)=3[/tex]
[tex]x(1)=1,y(1)=-6[/tex]
Put t=1 in each parametric equation.
In option A,
[tex]x(1)=-5+1=-4\neq 1[/tex]
In option B,
[tex]x(1)=-5+3(1)=-5+3=-2\neq 1[/tex]
In option D,
[tex]x(1)=-5+8(1)=-5+8=3\neq 1[/tex]
Therefore, options A, B and D are incorrect.
In option C,
[tex]x(1)=-5+6(1)=-5+6=1[/tex]
[tex]y(1)=3-9(1)=3-9=-6[/tex]
Put t=0 in x(t) and y(t).
[tex]x(0)=-5+6(0)=-5[/tex]
[tex]y(0)=3-9(0)=3[/tex]
Since, only in option C [tex]x(0)=-5,y(0)=3,x(1)=1,y(1)=-6[/tex], therefore, the correct option is C.
Answer:
C. x(t) = –5 + 6t; y(t) = 3 – 9t

Rewrite the expression with a rational exponent as a radical expression.
three to the two thirds power all raised to the one sixth power
Answer:
[tex]\huge\boxed{\sqrt[9]{3}}[/tex]
Step-by-step explanation:
In order to convert the expression [tex](3^{\frac{2}{3}})^{\frac{1}{6}}[/tex] into a radical, we need to simplify it down first.
Using exponent rules, we know that [tex](a^b)^c[/tex] can be simplified to [tex]a^{b\cdot c}[/tex].
Therefore we can say that [tex](3^{\frac{2}{3}})^{\frac{1}{6}}[/tex] is the same as [tex]3^{\frac{2}{3} \cdot \frac{1}{6}}[/tex].
[tex]\frac{2}{3} \cdot \frac{1}{6} = \frac{2}{18} = \frac{1}{9}[/tex]
So we have [tex]3^{\frac{1}{9}}[/tex].
When we have a number to a fraction power, it's the same thing as taking the denominator root of the base to the numerator power.
Basically:
If we have [tex]2^{\frac{3}{4}}[/tex]:
We'll take the denominator root (the denominator is 4) of the base (2):
[tex]\sqrt[4]{2}[/tex]
But inside the radical, we raise the base to the numerator (3) power.
[tex]\sqrt[4]{2^3}[/tex]
Same logic for [tex]3^{\frac{1}{9}}[/tex]
[tex]\sqrt[9]{3^1}[/tex]
[tex]3^1[/tex] is the same as 3.
[tex]\sqrt[9]{3}[/tex]

What factors of 32 add up to -12
Answer: -8 and -4
This is something you do through trial and error. Making a list or a table like shown below might help.
For what value of x will the relation R not be a function? R:{(2x,7),(8,3)}
Answer:
x=4
Step-by-step explanation:
The answer is 4 because 2 multiplied by x has to equal x2 or 8. So divided 8 and 2, so you get the answer of 4. Since the numbers are the same the relation of R won't be a function.
Solve the following inequality. 2 x < 8
Answer:
x < 4
Step-by-step explanation:
Step 1: Write inequality
2x < 8
Step 2: Divide both sides by 2
x < 4
We see here that any value of x less than 4 will work. So numbers like 1, 0, -124 or even -14687206589174 would work.
Answer:
X could = 1,2, or 3
Step-by-step explanation:
2x1=2 2x2=4 and 2x3=6
All if these examples are less than 8
Also anything negative ir zero would work also

What was Buffalo's snowfall rate? Round your answer to the nearest hundredth.
Do not include units (inches per hour) in your answer.
Answer:
Buffalo's snowfall rate is 1.83
Step-by-step explanation:
Rate of change
It usually refers to how fast one quantity changes with respect to another, frequently time.
In our problem, we are given the information on two snowfall rates, one during the winter of 2012–2013 in Buffalo, New York, and the other in Oswego, New York. Buffalo received 22 inches of snow in 12 hours. It means the rate of change or ratio of snowfall in time is:
[tex]\boxed{\displaystyle s_1=\frac{22}{12}=1.83}[/tex]
The snowfall rate received by Oswego is:

What is the conditional of a capital letter is a vowel if and only if it is symmetrical
Answer:
If the capital letter is symmetrical, only then would the letter be a vowel.
Step-by-step explanation:
Note, in logic a conditional statement or sentence refers to a statement that has a hypothesis (assumed condition), with a conclusion (or results).
In other words, the conditional statement is saying that a certain event would occur if the first condition is true.
For example, saying: if today is Monday, only then would tomorrow be Tuesday.

Greetings from Brasil...
F(V) = - 11V² - 8
F(a + h) - F(a)]/h
let's do it by steps
F(a + h) = - 11 · (a + h)² - 8
F(a + h) = - 11 · (a² + 2ah + h²) - 8
F(a + h) = - 11a² - 22ah - 11h² - 8
and
F(a) = - 11 · (a)² - 8
F(a) = - 11a² - 8
Then
F(a + h) - F(a)]/h
{- 11a² - 22ah - 11h² - 8 - [- 11a² - 8]}/h
[- 11a² - 22ah - 11h² - 8 + 11a² + 8]/h
[- 22ah - 11h²]/h
h · [- 22a - 11h]/h
[- 22a - 11h]Estimate the product.

Consider the following scenario in email filtering. You know based on your data that 10% of messages sent out are phishing attempts. Now, you look for a few keywords to improve your estimate of whether a particular message is a phishing email. In particular, you see two interesting words in a message you are considering that might indicate that the message is or is not a phishing email. These words and the likelihood that they appear in both a phishing and non-phishing message are listed below. Apply Bayes rule to update the probability that the message is a phishing email once for each word and give the final probability that the message is a phishing email. Note that your prior for the second update is based on the posterior probability after applying Bayes rule for the first word.

Step-by-step explanation:

Probability of phishing email given the word urgent is 0.45.
Probability of phishing email given the word password is 0.53.
What is Bayes' Rule?Bayes' rule is most powerful rule in probability which states that,
P(A|B) = [ P(B|A) P(A) ] / P(B)
Given that,
P(phishing) = 10% = 0.1
P(not phishing) = 1 - 0.1 = 0.9
P(urgent | phishing) = 0.15
P(urgent | not phishing) = 0.02
P(password | phishing) = 0.10
P(password | not phishing) = 0.01
P(urgent) = P(urgent | phishing)P(phishing) + P(urgent | not phishing)P(not phishing)
P(urgent) = 0.033
Similarly, P(password) = 0.019
By Bayes' Rule,
P(phishing | urgent) = [P(urgent | phishing) P(phishing)] / P(urgent)
= (0.15 × 0.1) / 0.033
= 0.45
P(phishing | password) = [P(password| phishing) P(phishing)] / P(password)
= (0.10 × 0.1) / 0.019
= 0.53
Hence the probability of phishing email given for each word is found.
