Compute the coefficient of determination. Round your answer to four decimal places. A regression equation is obtained for a set of data points. It is found that the total sum of square is 103.5, the regression sum of squares is 89.8, and the error sum of squares is 13.7.
a. 0.1324
b. 0.1526
c. 0.8676
d. 1.1526
Answer:
0.8676
Step-by-step explanation:
Given that :
Total Sum of Square (SST) = 103.5
Regression Sum of Square (SSR) = 89.8
Erroe Sum of Square (SSE) = 13.7
The Coefficient of determination (R²) :
R² = SSR / SST
R² = 89.8 / 103.5
R² = 0.8676328
R² = 0.8676

What is 2 1/2 - 3/8 as a fraction
Answer:
[tex]\frac{17}{8}[/tex] or [tex]2\frac{1}{8}[/tex]
Step-by-step explanation:
First we will convert the first term into an improper fraction. We multiply the whole number into the denominator and add the product to the numerator.
[tex]2\frac{1}{2}[/tex][tex]-\frac{3}{8}[/tex]
[tex]\frac{5}{2}[/tex][tex]-\frac{3}{8}[/tex]
Then we will multiply the first term by 4/4 to match the denominator of the second term..
[tex]\frac{5}{2}[/tex] * [tex]\frac{4}{4}[/tex] = [tex]\frac{20}{8}[/tex]
Finally we subtract.
[tex]\frac{20}{8}[/tex][tex]-\frac{3}{8}[/tex] = [tex]\frac{17}{8}[/tex]
The solution of the given fractional expression is 17/8.
What is a fraction?A fraction is a numerical quantity that represents a part of a whole or a quotient of two quantities. It consists of a numerator (the top number) and a denominator (the bottom number), separated by a horizontal line.
The numerator represents the number of equal parts being considered, while the denominator represents the total number of parts that make up the whole.
First convert the mixed fraction into the whole fraction and solve further to get the final solution.
The given fractional expression will be solved as,
[tex]E = 2\dfrac{1}{2}-\dfrac{3}{8}\\\\E = \dfrac{5}{2}-\dfrac{3}{8}\\\\E = \dfrac{20-3}{8}\\\\E = \dfrac{17}{8}[/tex]
Hence, the solution will be 17/8.

YALL I NEED HELP ASAP!!
Answer:
32
Step-by-step explanation:
You use angle chasing. Since a triangle's angle has to add up to 180, the other angle is 180-79-69. This gives 32. So angle E is 32 degrees. Since they are parallel, that means that E equals to D. That means that D is 32, so 32 is now the answer.

Step-by-step explanation:
In an interval whose length is z seconds, a body moves (32z + 2z^ 2 ) ft. What is the average speed v of the body in this interval?
This question is incomplete, the complete question is;
In an interval whose length is z seconds, a body moves (32z + 2z²) ft.
What is the average speed v of the body in this interval?
Answer: the average speed v of the body in this interval is 32 + 2z ft/s
Step-by-step explanation:
Given that;
Length of travel = z seconds
also the body moves (32z + 2z²) ft
i.e
distance travelled = (32z + 2z²) ft
average speed v of the body in this interval = ?
Now to get the Average Speed
we simply say;
Average Speed V = (32z + 2z²) / z
Average Speed V = 32 + 2z ft/s
Therefore the average speed v of the body in this interval is 32 + 2z ft/s

The domain is {-3,0,4}
the range is {-5,0,1,7}
not a function
#8
D={3,6,12,18}
R={5,7,9,10}
not a function
Step-by-step explanation:
First, 7.
the domain is the all of the x values, in numerical order, listed once, even if it repeats.
D={-3,0,4} (notice how -3 is listed twice; despite that, we only list it once)
the range is all of the y values, in numerical order, listed once, even if the numbers repeat
R={-5,0,1,7}
A function can have the range (y values) repeat, however, the domain (x values) cannot repeat.
Therefore, this is not a function, since -3 is listed twice.
For 8.
The domain, can be listed as
D={3,6,12,18}
And the range as
R={5,7,9,10}
Notice how it says that if 6 is the input (x), the output (y) can be 5 or 10. Since we said the domain CANNOT repeat, this isn't a function.
Hope this helps!

The distance a spring will stretch varies directly how much weight is attached to the spring if a spring stretches 6 inches with 80 pounds attached how far will it stretch with 55 pounds attached? Round to the nearest 10th of an inch
Answer:
The spring will stretch 4.1 inches
Step-by-step explanation:
Direct Proportions
A direct proportion is a relation between variables where their ratio is a constant value. This means that if y and x are proportional, then:
y = kx
Where k is the constant of proportionality.
Let's call:
y = distance a spring stretches
x = weight attached to the spring
We know when x=80 pounds, y=6 inches, thus:
6 = 80k
Solve for k:
[tex]k=\frac{6}{80}=\frac{3}{40}[/tex]
The equation is now:
[tex]\displaystyle y = \frac{3}{40}x[/tex]
When x=55 pounds are attached:
[tex]\displaystyle y = \frac{3}{40}\cdot 55[/tex]
Calculating:
y = 4.1 inches
The spring will stretch 4.1 inches

The ratio of Val's savings to Dan is 2:3 at first. After Dan spent P3000.00, Val's saving became 11/3 more of that Dan's remaining savings. What is the total amount of saving the two had at first
Answer:
P.7500.00
Step-by-step explanation:
We are told that:
The ratio of Val's savings to Dan is 2:3 at first.
Now, Dan spent P3000.00 and Val's saving became 1⅓ more of that Dan's remaining savings.
Let's say the total amount of savings they had at first was x.
Thus;
Val had: 2x/5
Dan had: 3x/5
Now, Dan spent P3000.00.
So amount Dan has left = (3x/5) - 3000
We are told Val's savings is now 1⅓ = 4/3 times that of Dan's remaining savings
Thus; 2x/5 = (4/3)((3x/5) - 3000)
2x/5 = 12x/15 - 4000
Multiply through by 15 to get;
6x = 12x - (3000 × 15)
6x = 12x - 45000
Rearranging, we have;
12x - 6x = 45000
6x = 45000
x = 45000/6
x = P.7500

What is area?An area is total space occupied by two-dimensional or flat surfaces. In other words we can say that it is a number of unit squares present in a closed figure. We use various units for measurement of area like, cm², m², ft², mm².
Area of square = a²
Area of rectangle = a × b
Area of circle = πr²
Given that,
The dimensions of the room are 200 feet by 180 feet
Each bottle of carpet shampoo can be used to shampoo 320 square feet of carpet
bottles of shampoo = ?
Total area we need to clean = 200 × 180
= 36000
one bottle can clean area = 320 square feet
number of bottles = Total area /one bottle can clean
number of bottles = 36000/320
= 112.5
≈ 113 bottles
So, The number of bottles required is 113
