Find the mean,median and range of the following list of values and choose the correct result.
8, 9, 10, 10, 10, 11, 11, 11, 12, 13
Mean: 10.5
Median: 10.5
Range: 5
--------------------------------------------
To find the mean you order the numbers then add then divide.
Add
8+9+10+10+10+11+11+11+12+13=105
Divide
105÷10=10.5
Mean = 10.5
--------------------------------------------
Finding the median essentially involves finding the value in a data sample that has a physical location between the rest of the numbers.
Find the middle number. Put your left finger on 8 and your right finger on 13. Move your left finger to the right to 10 and move your right finger to 11.
the middle number is 10.5 so therefore it is the median.
--------------------------------------------
To find the range you subtract the biggest number to the smallest number.
Subtract
13-8=5
Therefore 5 is the range
Answer:
The median is 10.5 the range is 5 and the mean is 10.5
Step-by-step explanation:
To find the median you have to cross out each number till you get 2 since there are 10 numbers together then add 10 and 11 and get 21 divide by 2 which gives you 10.5 to find the mean add all the numbers then divide 105 by 10 and get 10.5 to find the range take 13-8 and get 5
Suppose the length of an oarfish is normally distributed with a mean of 6.5 m and a standard deviation of 1.5 m. Which group describes 16% of the oarfish population? Select each correct answer. oarfish that are between 6.5 m and 9.5 m oarfish that are shorter than 5 m oarfish that are between 3.5 m and 9.5 m oarfish that are longer than 8 m
Answer:
Step-by-step explanation:
Let x be the random variable representing the length of an oarfish. Since it is normally distributed and the population mean and population standard deviation are known, we would apply the formula,
z = (x - µ)/σ
Where
x = sample mean
µ = population mean
σ = standard deviation
The given probability value is 16% = 0.16. From the normal distribution table, the z score corresponding to the probability value is - 0.99
This indicates that the sample mean is lower than the population mean
Therefore,
- 0.99 = (x - 6.5)/1.5
- 0.99 × 1.5 = x - 6.5
- 1.5 = x - 6.5
x = - 1.5 + 6.5
x = 5m
The correct answer is
oarfish that are shorter than 5 m
Answer:
oarfish that are shorter than 5
oarfish that are longer than 8 m

An airplane's change in altitude before landing is shown in the table. What equation
represents this change in altitude?
Answer:
Step-by-step explanation:
We have been given a table that represents the altitude of an airplane with passing minutes.
Since we know that equation of a line in slope-intercept form is: y=mx+b, where, m = Slope of the line and b = y-intercept.
To find the equation of line we will have to the slope of our given line using values from table.
m=\frac{y_2-y_1}{x_2-x_1}, where,
y_2-y_1 = Change in two y-coordinates.
x_2-x_1 = Change in the corresponding x-coordinates.
Upon substituting the coordinates of point (1, 35000) and (2, 31000) we will get our slope as:
m=\frac{31000-35000}{2-1}
m=\frac{-4000}{1}=-4000
Now let us find y-intercept of our given line by substituting m=-4000 and the coordinates of point (1, 35000) in slope intercept form of equation.
31000=-4000*1+b
31000=-4000+b
31000+4000=-4000+4000+b
35000=b
Upon substituting the value of slope and y-intercept the equation of line will be:
a=-4000m+35,000
Therefore, the equation representing the change in altitude a after m minutes is a=-4000m+35,000 and option A is the correct choice.

(80%) mortgage has an interest rate of 4.75%, and the second (20%)
mortgage has an interest rate of 7.525%. Both the first mortgage and the
second mortgage are 30-year fixed-rate mortgages. What is his total
mortgage payment for this house?
A. $730.31
B. $975.63
C. $245.32
D. $805.87
Answer:
Its b got it correct
The total monthly mortgage payment for the house is $975.63
What is percentage?A percentage is a number or ratio that can be expressed as a fraction of 100. A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.
here, we have,
The principle amount is $175000
80% of 175000 is = = $140000
20% of 175000 is = = $35000
Emi formula is :
p*r*(1-r)^n/(1-r)^n-1
For 1st part:
p = 140000
r = 4.75/12/100=0.00395
n = 360
Putting values in formula we get
= $729.508
For 2nd part:
p = 35000
r = 7.525/12/100=0.00627
n = 360
Putting values in formula we get
= $245.301
Adding both the monthly payments:
974.809 dollars
This is closest to option A.
So, option A is the answer.
And for 30 years the mortgage payment will be = 351226.80 dollars
Hence, The total monthly mortgage payment for the house is $975.63.

Step-by-step explanation:
Sam is transferring files from his friend's laptop into his flash drive. This is the formula for the size of the files on Sam's friends drive S (measured in megabytes) as a function of time t (measured in seconds): S(t)=5t+45
Use the above information to answer the following:
When the transfer began the drive had___ megabytes of files on it
Every 10 seconds, an additional___ megabytes are transferred into the drive.
Answer:
1. 45 megabytes
2. 50 megabytes
Step-by-step explanation:
Given
S(t) = 5t + 45
Required
Find S(t) when the transfer began
And find the additional transfer size at interval of 10 seconds
When the file transfer initially began, the value of t is 0.
Given that S(t)=5t+45.
Substitute 0 for t
S(0)=5 * 0 + 45
S(0) = 0 + 45
S(0) = 45.
Hence, the hard drive had 45 megabytes on it when the transfer started.
At every interval of 10 seconds. We take t to be 10, 20, 30...seconds
When t = 10
S(t)=5t+45 becomes
S(10) = 5(10) + 45
S(10) = 50 + 45
S(10) = 95 megabytes
When t = 20
S(t)=5t+45 becomes
S(20) = 5(20) + 45
S(20) = 100 + 45
S(20) = 145 megabytes
When t = 30
S(t)=5t+45 becomes
S(30) = 5(30) + 45
S(30) = 150 + 45
S(30) = 195 megabytes
Calculating the difference
Difference = S(30) - S(20) or S(20) - S(10)
Difference = 195 - 145 or 145 - 95
Difference = 50 or 50
See that the difference is the same.
So, at every 10 seconds interval, there's an additional 50 megabytes transferred
a pitcher contains 17.5 cups of iced tea. you drink 0.75 cup of tea each morning and 1.75 cups of tea each evening. when will you run out of iced tea?
Answer:
7 days
Step-by-step explanation:
Based on the amount of iced tea in the pitcher and the amount drank per day, you will run out of iced tea in 7 days.
The total number of cups drank per day is:
= 0.75 + 1.75
= 2.5 cups
With 2.5 cups being drank per day, the pitcher would last:
= Pitcher quantity / Cups per day
= 17.5/2.5
= 7 days
In conclusion, you will run out after 7 days.

The solutions to the equation n³+3n²+n-33=0 are n=-11, n=-3, and n=1.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
Given that, 9/(n²+1) = (n+3)/4.
Here, 9×4=(n²+1)×(n+3)
36=n²(n+3)+1(n+3)
36=n³+3n²+n+3
n³+3n²+n+3-36=0
n³+3n²+n-33=0
The equation n³+3n²+n-33=0 can be solved by factoring. The factors of -33 are -1 and 33. Since the coefficient of the n³ term is 1, this means that n-1 and n+33 are factors of the equation.
Dividing both sides of the equation by n-1, we get:
n²+3n+33/(n-1)=0
Factorizing the numerator, we get:
(n+11)(n+3)=0
Solving this equation, we get n=-11 and n=-3.
Therefore, the solutions to the equation n³+3n²+n-33=0 are n=-11, n=-3, and n=1.

Theoretical: 10/30 = 1/3
Experimental: 12/30 = 6/15
Step-by-step explanation:
the theoretical probability is if every number was rolled an equal amount of times. as there are 3 options and a number was chosen 30 times, if we divide 30 by 3 we will get the theoretical probability of choosing a 2
30 ÷ 3 = 10
the theoretical probability = 10/30 or simplified 1/3
the experimental probability is the result when one of the numbers from

What is the measure of AngleJHN? 25° 45° 50° 95°
Answer:
95 is the answer!
The measure of the angle ∠JHN will be 45°. Then the correct option is B.
What is an angle?The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360 °.
Vertically opposite angle - When two lines intersect, then their opposite angles are equal.
Angle ∠MHL and angle ∠JHK are equal because the angles are opposite angles.
∠MHL = ∠JHK
3x + 20 = x + 20 + x + 25
x = 25
Then the measure of the angle ∠JHN is calculated as,
∠JHN = x + 20
∠JHN = 25 + 20
∠JHN = 45°
The measure of the angle ∠JHN will be 45°. Then the correct option is B.
