Answer:
Step-by-step explanation:
If a family has 7 children, what is the interval within which "the number of children they have" really falls.
Now, number of children is a discrete variable, not a continuous one.
You are sure that the family has 7 children because the question states that.
The true interval within which the number of children they have falls is (0 - 8)
The sum of three numbers is 110. The third number is 3 times the second. The first number is 5 less than the second. What are the numbers?
Answer:
1. 18
2. 23
3. 69
Step-by-step explanation:
y= 23
check it for your self
Answer:
18, 23 and 69
Step-by-step explanation:
Let x, y and z be the 3 numbers we are looking for.
● x + y + z = 110
z is 3 times y (z = 3y)
● x + y + 3y = 110
x is 5 less than y ( x = y -5)
● y-5 + y + 3y = 110
● 5y -5 = 110
Add 5to both sides
● 5y + 5 -5 = 110+5
● 5y = 115
Divide both sides by 5
● 5y/5 = 115/5
● y = 23
■■■■■■■■■■■■■■■■■■■■■■■■■
we have found that y = 23
● z = 3y
● z = 3×23
● z = 69
● x = y-5
● x = 23-5
● x = 18
For items 21 - 23 determine whether each sequence is arithmetic. if the sequence is arithmetic, then
Answer:
see below
Step-by-step explanation:
To be arithmetic we have to add the same term each time
1,1,2,3,5,8
1+1 =2 2+1 = 3 3+1 = 4 so it is not arithmetic
20,17,14,11,8,....
Add -3
20+-3 =17 17+-3 = 14 14+-3 = 11 11+-3 = 8
This is an arithmetic sequence
The common difference is -3
The explicit formula is
an = a1+ d(n-1) where d is the common difference and a1 is the first term
an = 20 -3( n-1)
The recursive formula is
an = an-1 + d where an-1 is the previous term and d is the common difference
an = an-1 -3
3,7,11, 15
Add 4
3+4=7 7+4=11 11+4=15
This is an arithmetic sequence
The common difference is 4
The explicit formula is
an = a1+ d(n-1) where d is the common difference and a1 is the first term
an = 3 +4( n-1)
The recursive formula is
an = an-1 + d where an-1 is the previous term and d is the common difference
an = an-1 +4
One number is 3/8 of another number. The difference of the two numbers is 4.2. What is the lesser number
Answer:
2.52.
Step-by-step explanation:
If one number is x then the other = 3x/8.
Also x - 3x / 8 = 4.2
x - 0.375 x = 4.2
0.625x = 4.2
x = 4.2 / 0.625
x = 6.72.
So the lesser number is 6.72 * 0.375 = 2.52.
The lesser number is 2.52
If that one number is x, then we can agree that the other number is 3x/8.
Again, we are told that the difference between both is 4.2. Which means
x - (3x / 8) = 4.2
(8x - 3x)/8 = 4.2
8x - 3x = 8 * 4.2
5x = 33.6
x = 33.6/5
x = 6.72.
This means that the lesser number is 6.72 * 0.375 = 2.52.

Write an equation for the nth term of the sequence 4, 12, 36, 108, .
Answer:
26,244
Step-by-step explanation:
First, find the pattern with the numbers you already have. That pattern is × 3.
Since you're already at the fourth term, just keep multiplying your product by 3 until you get to the ninth term.
108 × 3 = 324
324 × 3 = 972
972 × 3 = 2,916
2916 × 3 = 8748
8748 × 3 = 26244
Therefore, your answer is 26,244.
A city has a population of 12,961. How many people can fit on the football field if the field is
80 yards long and 45 yards wide? Can the population fit? Each person occupies 2.5 square feet
of space.
(3 Points)
Unit Conversion Factors Chart
1 foot
1 inch = 2.54 centimeters
12 inches
1 yard = 3 feet
0.621 miles = 1 kilometer
1 mile = 5,280 feet
1 meter = 100 centimeters
Answer/Step-by-step explanation:
Given:
Population = 12,961
Dimension of field:
length (l) = 80 yards = 80*3 = 240 ft (1 yd = 3 ft)
width (w) = 45 yards = 45*3 = 135 ft
Area of the field = l*w = 240*135 = 32,400 ft²
Area occupied by 1 person = 2.5 ft²
No of people the field can occupy = 32,400 ÷ 2.5 = 12,960
Exactly 12,960 people can fit into the field.
The population of the city, which is 12,961, is more than what the field can accommodate. Therefore, the population cannot fit in.
Class: Constructing graphs Student Activity Sheet 2; Exploring "Representing data" Date Page 2 of 7 3. What do you notice about the vertical axis used in Graph A? How does this affect the way the data are displayed? FA Graph A 24 The 520 16 Benton population in 1000s 12 2002 2004 2008 2008 2010 Year.
Answer:
Explained below.
Step-by-step explanation:
The vertical axis of Graph A represents the year for which the population of Benton is recorded.
Also the axis represents every other year, i.e. 2002, 2004, 2006 and so on.
This implies that the data is recorded for every other year.
Consider the data provided:
Benton population in 1000s Year
10 2002
11 2004
12 2006
13 2008
14 2010
For every 2 years the population of Benton is increasing by 1000.
That is for every year the population of Benton is increasing by 500.
If we make the vertical axis using the years:
2001, 2002, 2003, 2004, 2005, 2006 and so on, the graph will remain same with more points to plot.
So, on altering the vertical axis the graph does not changes much.

Suppose Robert invests $1,200 in the CD for a period of 3 years. How much interest will he earn? How much will Robert have after 3 years?
Answer:
1. The interest is $ 117.
2. The amount is $ 1,317.
Step-by-step explanation:
The following data were obtained from the question:
Principal (P) = $ 1,200
Rate (R) = 3.25%
Time (T) = 3 years
Interest (I) =..?
Amount (A) =...?
1. Determination of the interest.
Principal (P) = $ 1,200
Rate (R) = 3.25%
Time (T) = 3 years
Interest (I) =..?
I = P × R × T / 100
I = 1200 × 3.25 × 3 / 100
I = $ 117
Therefore, the interest is = $ 117
2. Determination of the amount.
This can be obtained as follow:
Interest (I) = $ 117
Principal (P) = $ 1,200
Amount (A) =?
Amount (A) = principal (P) + interest (I)
A = P + I
A = 1200 + 117
A = $ 1,317
Therefore, the amount at the end of 3 years is $ 1,317

Find an equation of the tangent plane to the surface at the point . Question 14 options: a) b) c) d) e)
This question is incomplete, the complete question is;
Find an equation of the tangent plane to the surface z=1y²−1x² at the point (-4, 3, -7).
z = .....................
Note: Your answer should be an expression of x and y; e.g. 3x - 4y + 6.
Answer:
Z = 8x + 6y + 7
Step-by-step explanation:
Given that z = 1y² - 1x²
with points (-4, 3, -7)
so
Z = y² - x²
Equation of tangent plane to the surface Z = f(x,y) at the points ( x₀,y₀,z₀) is
Z - Z₀ = fx (x₀,y₀)(x-x₀) + fy (x₀y₀)(y-y₀)
therefore
Z = f(x,y) = y² - x²
fx = -2x, fx (-4, 3, -7) = -2(-4) = 8
fy = -2y, fy ( -4, 3, -7 ) = 6
Z + 7 = 8(x+4) + 6(y-3)
Z + 7 = 8x + 32 + 6y - 18
Z + 7 = 8x + 32 + 6y - 18
Z + 7 = 8x + 6y + 14
Z = 8x + 6y + 14 - 7
Z = 8x + 6y + 7

Are two squares with the same side lengths scaled copies of one another? Explain your reasoning.
Answer:
Yes.
Step-by-step explanation:
Two squares with the same side lengths will always be a scale copy. Every side is equal because all sides are the same length if it wasn't that way it would be a rectangle or trapezoid.
A rectangle whose all sides are equal is called a square. The two squares with the same length side will be lengths scaled copies of one another.
What is a square?A rectangle whose all sides are equal is called a square.
A square is always a rectangle, parallelogram, and a quadrilateral but its reverse statement may or may not be true.(ie it is not always necessary that a rectangle is a square or a parallelogram is a square).
As it is known that two squares are always similar to each other which is because all the angles of a square are always 90°. Therefore, any two squares are always similar to each other.
Now, as it is given that the two square have the same length sides. Therefore, the two squares with the same length side will be lengths scaled copies of one another. This is because all the sides are equal and all the angles are equal.
Hence, the two squares with the same length side will be lengths scaled copies of one another.
