A number's square root multiplied by another number's square root does not always equal the total of these two numbers' square roots.
Why is it called sum of squares?A statistical method called the sum of squares (SS) is used in regression analysis to determine how well the data can fit the model and how dispersed the data are. Since it is determined by adding up the squared differences, the sum of squares is how it is calculated.
A sum's square is equal to the product of its summands' squares and its double products' sums of summands in twos.
So, it is not always true that the square root of a sum is equal to the sum of the square roots.

Why is it called sum of squares?In regression analysis, the sum of squares (SS), a statistical technique, is used to assess how well the data fit the model and how distributed they are. The sum of squares is used to compute it as it is obtained by combining together the squared differences.
The product of a sum's square and its double products' sums of its summands in twos is known as the summands' square. Hence, the square root of such a sum is not necessarily equal to the total of the square roots.

Step-by-step explanation:
The upper-left coordinates on a rectangle are (- 8, 8) and the upper-right coordinates are (- 3, 8) The rectangle has an area of 15 square units
Answer:
See attachment for diagram
Step-by-step explanation:
Given
[tex](x_1,y_1) = (-8,8)[/tex]
[tex](x_2,y_2) = (-3,8)[/tex]
[tex]Area = 15[/tex]
Required
Draw the rectangle on a coordinate plane --- (missing from the question)
First, we calculate the distance between the given pairs.
[tex]D = \sqrt{(x_1 - x_2)^2 + (y_1-y_2)^2}[/tex]
[tex]D = \sqrt{(-8-(-3))^2 + (8-8)^2}[/tex]
[tex]D = \sqrt{25}[/tex]
[tex]D = 5[/tex]
So, the distance between the given pairs is 5 units... Let this be the length of the rectangle.
Using:
[tex]Area = Length * Width[/tex]
[tex]15 = 5 * Width[/tex]
[tex]Width = \frac{15}{5}[/tex]
[tex]Width = 3[/tex]
The width is 3 units.
This implies that the opposite sides of the rectangle are either 3 units down or 3 units up the given pairs.
Assume they are 3 units up.
[tex](x_1,y_1) = (-8,8)[/tex] and [tex](x_2,y_2) = (-3,8)[/tex]
[tex](x_3,y_3) = (x_1,y_3 + 3) = (-8,8+3) = (-8,11)[/tex]
[tex](x_4,y_4) = (x_2,y_2 + 3) = (-3,8+3) = (-3,11)[/tex]

PLEASE HELP, I DON'T UNDERSTAND THE WORDING
Answer:
C. 8 miles per hour
Step-by-step explanation:
It takes Diego [tex]\frac{1}{8}[/tex] of an hour to complete the lap = [tex]\frac{1}{8}[/tex] x 1 hour = [tex]\frac{1}{8}[/tex] hour
Distance of the track = 1 mile long
The speed of an object expresses the ratio of distance moved to time taken to cover the distance.
i.e speed = [tex]\frac{distance}{time taken}[/tex]
= [tex]\frac{1}{\frac{1}{8} }[/tex]
= 8
Speed = 8 mile per hour
Therefore, Diego's bike has a speed of 8 miles per hour.

Sam surveyed his classmates to find out if they played a sport after school or practiced in the
school band
- 14 of his classmates played a sport
- of those 14 who played, 5 participated in the school band
- 8 students played in the school band, and out of those 8, 3 did not play sports
- there were 10 students who did not play a sport nor participate in the school band

- of those 14 who played, 5 participated in the school band
- 8 students played in the school band, and out of those 8, 3 did not play sports
- there were 10 students who did not play a sport nor participate in the school band
Create a two way table to represent the data and answer the following questions
Step-by-step explanation:
Here is a two-way table that represents the given data:
Look at the pic
To create this table, we first divided the students into two categories: those who play a sport and those who do not. Then, we further divided each category into those who play in the school band and those who do not.
From the table, we can answer the following questions:
How many students did Sam survey in total?
To find the total number of students surveyed, we can add up the values in the table:
14 + 5 + 3 + 9 + 10 = 41
Therefore, Sam surveyed a total of 41 students.
How many students played a sport but did not participate in the school band?
From the table, we can see that 14 students played a sport, and 5 of those also participated in the school band. Therefore, the number of students who played a sport but did not participate in the school band is:
14 - 5 = 9
So, 9 students played a sport but did not participate in the school band.
How many students did not play a sport but participated in the school band?
From the table, we can see that 8 students played in the school band, and 3 of those did not play a sport. Therefore, the number of students who did not play a sport but participated in the school band is:
8 - 3 = 5
So, 5 students did not play a sport but participated in the school band.

question: find the value of t
Answer:
t = 5
Step-by-step explanation:
since those 2 angles make up 180 degrees turn it into an equation
20t + 5 + 15t = 180
combine like terms 20t + 15t = 35t
the equation is now 35t + 5 = 180
subtract 5 from both sides, 5 - 5=0, 180 - 5 = 175
35t = 175
now divide each side by 35, 35t/35 = t, 175/35= 5
t = 5
hope this helps :)
Answer:
5
Step-by-step explanation:
Line (which has the the equation)= 180
So,
15t + 20t + 5 = 180
35t + 5 = 180
35t = 180 - 5
35t = 175
t = 175/35
t = 5
An online furniture store sells chairs and tables. Each day, the store can ship at most 25 pieces of furniture. Write an inequality that could represent the possible values for the number of tables sold, t, and the number of chairs sold, c, that would satisfy the constraint.
9514 1404 393
Answer:
t + c ≤ 25
Step-by-step explanation:
"At most 25" means "less than or equal to 25." The total number of pieces of furniture is the sum of the numbers of tables and of chairs: t + c.
The shipping constraint can be written as ...
t + c ≤ 25

On a map, the distance between Louisville, Kentucky, and Nashville, Tennessee, is 1 3/4 inches. The scale of the map is 1 in:100 mi. What is the actual distance between the two cities?
Answer:
Step-by-step explanation:
The distance between 2 cities is 175 miles
What is scale on graph?
A scale is a set of numbers that help to measure or quantify objects. A scale on the graph shows the way the numbers or pictures are used in data.
Given data ,
The distance between Louisville and Nashville = 1 3/4 inches
Scale of the map = 1 in : 100 miles
Now , 1 inch = 100 miles on the map
And , 1 3/4 = 7 / 4 inches
So , 7 / 4 inches = ( 7 / 4 ) x 100 miles
= 1.75 x 100 miles
= 175 miles
Hence , the distance between 2 cities is 175 miles

Sara bought 12 feet of fabric to make curtains. She needs to cut it into 1/4 foot sections. How many sections of fabric will she have.
Answer: 48 sections
Step-by-step explanation:
Sara bought 12 feet of fabric. From that 12 feet, she needs to cut out sections that are 1/4 in length.
The number of sections she will have if she does so is:
= Total length of fabric / Length of sections
= 12 ÷ 1/4
= 12 * 4/1
= 48 sections

Answer: y=(4/3)x-2
Step-by-step explanation:
(y-y1)/(x-x1)=(y2-y1)/(x2-x1)
x1=0, x2=6
y1=-2, y2=6
(y-(-2))/(x-0)=(6-(-2))/(6-0)
(y+2)/(x)=(6+2)/6
(y+2)/(x)=8/6=4/3
Cross multiply
3(y+2)=4x
y+2=(4/3)x
y=(4/3)x-2
A woman is standing 12 feet from a sculpture. The angle of elevation from her eyes to the top of the sculpture is 35º. If the woman's eyes are 5 feet 6 inches off the ground, how tall is the sculpture? Round answer to the nearest thousandth of a foot.
Answer:
13.903 feet
Step-by-step explanation:
Let the height from the woman's eyes to the top of the sculpture be represented by x.
So that,
Tan 35 = [tex]\frac{x}{12}[/tex]
x = Tan 35 x 12
= 0.70021 x 12
= 8.4025
x = 8.403 feet
The height of the sculpture = The woman's eye level to the ground + x
= 5 feet 6 inches + 8.403 feet
= 5.50 feet + 8.403 feet
= 13.903 feet
Thus, the sculpture has a height of 13.903 feet.
