Answer:
D. 6
Step-by-step explanation:
⇒The question is on Sum of Squared Errors(SSE)
⇒A linear regression equation is one inform of Y= a +bx where Y is dependent variable and x is the independent variable where as b is the slope.
⇒SSE for a set of data is the sum of squares of the calculated residuals where a residual/error is a deviation of a point from that in the line of best fit.
⇒General expression; y₁-y₀ where y₁ is the point out of the line and y₀ is the point in the line of best fit.
⇒ y₁-y₀ =ε₀................where ε is epsilon
⇒sum= (ε₀)² + (ε₁)² + (ε₂)²
ε₀= a (3,6).......A (3,7)......(6-7)² = -1² = 1
ε₁= b (6,8).......B (6,6).......(8-6)²= 2²= 4
ε₂= c (9,4).......C (9,5).......(4-5)²= -1² = 1
Sum of squares is = 1+4+1= 6
See attached graph showing the points on the line and those out of the line.
First you want to put them in order from least to greatest.
65, 72, 74, 75, 86, 89, 93, 95, 96, 97, 100.
Now you count the numbers on the left and right until you get to the middle, there is an uneven number so therefor you wont have to do any extra math.
65, 72, 74, 75, 86, 89, 93, 95, 96, 97, 100. there is 5 on each side 89 being the median.
Now moving onto the mode. You will need all of them for this not taking out the ones of there being multiple.
95, 95, <span>96, 100, </span>86, 75, 75, 75, 74, 72, 89, 97, 93, 65
You need to find the number that there is the most of to find the mode. to do this keep score of how many of each of the numbers there is
95, 95, 96, 100, 86, 75, 75, 75, 74, 72, 89, 97, 93, 65 The most commonly occuring number is 75 in this dataset.
Reviewing our answers.
In the end the median is 89 and the mode is 75

Answer:
57 children
54 adults
Step-by-step explanation:
Let's call x the number of children admitted and call z the number of adults admitted.
Then we know that:
We also know that:
We want to find the value of x and z. Then we solve the system of equations:
-Multiplay the first equation by -4 and add it to the second equation:
----------------------------------
Now we substitute the value of x in the first equation and solve for the variable z
