You ask 100 randomly chosen dog owners in your town how many dogs they own. The results are shown in the table. There are 500 dog owners in your town.
Mean: _???_ dogs per owner.
The mean number of dogs per owner in your town is 1.63 dogs
What is Mean?The mean value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.
Mean = Sum of Values / Number of Values
Given data ,
To find the mean (average) number of dogs per owner in your town, we can use the formula:
Mean = (Sum of all values) / (Total number of values)
From the table, we can calculate the sum of all values by multiplying the number of dogs by their respective frequencies and adding them up:
(1 * 54) + (2 * 38) + (3 * 3) + (4 * 1) + (5 * 4) = 54 + 76 + 9 + 4 + 20 = 163
The total number of values (or dog owners) in your town is given as 100.
Plugging these values into the formula, we get:
Mean = 163 / 100
Mean = 1.63 (rounded to two decimal places)
Hence , the mean number of dogs per owner in your town is approximately 1.63 dogs

All digits in a dropdown number are different, and one of its digits is the average of all its digits. It has at least two digits. For example, 5021 is a dropdown number, but neither 4389 nor 6033 is a dropdown number.
Questions:
1. Find the smallest dropdown number.
2. What are the smallest and largest 4-digit dropdown numbers?
3. How many 3-digit dropdown numbers are there?
4. Is it possible for a pair of consecutive numbers to both be dropdown numbers? If not, explain why not. If it is possible, find the smallest such pair.
1. Start the search among 2-digit numbers. A dropdown number (DDN) with 2 digits is a number [tex]ab[/tex] such that
[tex]\dfrac{a+b}2 = a \implies a + b = 2a \implies b = a[/tex]
or
[tex]\dfrac{a+b}2 = b \implies a+b = 2b \implies a=b[/tex]
but both of these solutions violate the requirement that the digits are distinct, so there are no 2-digit DDNs.
A 3-digit DDN [tex]abc[/tex] is such that
[tex]\dfrac{a+b+c}3 = a \implies a+b+c = 3a \implies b+c = 2a[/tex]
or [tex]a+c=2b[/tex] if the average is [tex]b[/tex], or [tex]a+b=2c[/tex] if the average is [tex]c[/tex]. The smallest possible value for [tex]a[/tex] is 1 since we require 3 digits. Then [tex]b+c=2[/tex], and we can pick [tex]b=0[/tex] and [tex]c=2[/tex] to get the smallest DDN, 102.
2. In a 4-digit DDN [tex]abcd[/tex], we have
[tex]\dfrac{a+b+c+d}4 = a \implies a + b + c + d = 4a \implies b+c+d=3a[/tex]
or [tex]a+c+d=3b[/tex] or [tex]a+b+d=3c[/tex] or [tex]a+b+c=3d[/tex].
We're free to fix [tex]a=1[/tex] and [tex]b=0[/tex] to try to get the smallest DDN. This leaves us with [tex]c+d=3[/tex] or [tex]c+d=-1[/tex] or [tex]1+d=3c[/tex] or [tex]c=3d[/tex].
The first two cases are impossible - the only choices for [tex]c,d[/tex] such that [tex]c+d=3[/tex] are 1 and 2, and the sum of two positive integers must be positive. The smallest possible value of [tex]c[/tex] is 2; this leaves us with [tex]1+d=6[/tex] or [tex]2=3d[/tex], but the latter case is impossible because 3 does not divide 2. So [tex]d=5[/tex], and the smallest 4-digit DDN is 1025.
To find the largest DDN, start with the largest possible values for [tex]a[/tex] and [tex]b[/tex]. Let [tex]a=9[/tex] and [tex]b=8[/tex]. Then [tex]c+d=19[/tex] or [tex]c+d=15[/tex] or [tex]17+d=3c[/tex] or [tex]17+c=3d[/tex]. At most, we can have [tex]c+d=13[/tex] with 7 and 6, so the first two cases are impossible. If we maximize [tex]c=7[/tex], then either [tex]17+d=21\implies d=4[/tex] or [tex]24=3d\implies d=8[/tex] (which we don't want). So the largest 3-digit DDN is 9874.
3. I don't have an analytical solution to this, but using brute force (program) the total count is 112.
4. It is possible; consider 1249 and 1250, with digital averages
[tex]\dfrac{1+2+4+9}4=4 \text{ and } \dfrac{1+2+5+0}4=2[/tex]
which happens to be the smallest pair. (Also found with brute force.)

We can measure temperature in two different common units: degrees Celsius and degrees Fahrenheit.
The variable F represents the temperature in degrees Fahrenheit that is equivalent to CCC, the temperature in degrees Celsius.
F=32+1.8CF=32+1.8CF, equals, 32, plus, 1, point, 8, C
What is the temperature increase in degrees Fahrenheit that is equivalent to a temperature increase of 10 degrees Celsius?
Answer:
Step-by-step explanation:
Thank you for asking this question. Here is your answer:
1/2 The increase in temperature by 10
10°C
Times the unit rate of the conversion function.
2/2 F
is given in slope-intercept form, so the slope of the graph is 1.8
This means the unit rate is 1.8°F / 1°C
Therefore, for 10°C
The increase in Fahrenheit is
10⋅1.8
= 18°F

On a electricity bill of $14.80, mrs.miller pays only $38.76 because she pays a certain date. what percent discount is mrs.miller allowed?
Answer:
I assumed that you made a mostake and meant:
On a electricity bill of $38.76, mrs.miller pays only $14.80 because she pays a certain date. what percent discount is mrs.miller allowed?
62% approx
Step-by-step explanation:
$38.76 - $14.80 = $23.96
23.96/38.76 = 61.8%
Mrs. Miller is allowed a discount of approximately 5% on her electricity bill.
To calculate the percent discount that Mrs. Miller is allowed on her electricity bill, we can use the following formula:
Percent discount = (Discount amount / Original amount) * 100
In this case, the original amount of the bill is $40.80, and Mrs. Miller pays only $38.76, which means she receives a discount of $40.80 - $38.76 = $2.04.
Now, let's calculate the percent discount:
Percent discount = ($2.04 / $40.80) * 100 ≈ 5%
The discount is given as a percentage of the original bill amount and represents the amount saved by Mrs. Miller due to paying on a certain date or any other special offer provided by the electricity company. By paying $38.76 instead of $40.80, she saves $2.04, which is 5% of the original bill.

Select all equations that have graphs with the same y-intercept.
Select all that apply:
A) y = 3x - 8
B) y = 3x - 9
C) y = 3x + 8
D) y = 5x - 8
E) y = 2x - 8
F) y = (1/3)x - 8
Answer: A, C, D, E, and F have the same y-intercepts.
Step-by-step explanation:
The Equation for graph A has a y-intercept of -8
The Equation for graph B has a y=intercept of -9
The Equation for graph C has a y-intercept of -8
The Equation for graph D has a y-intercept of -8
The Equation for graph E has a y-intercept of -8
The Equation for graph F has a y-intercept of -8
The only difference between the y-intercepts of the equations is the equation for graph B, it has a y-intercept of -9 so it will not be the same as the other equations with the same y-intercepts. \
A, C, D, E, and F have the same y-intercepts.

Answer:
30
Step-by-step explanation:
Since 5 and 6 are coprime, the least common multiple is their product, which is 30.
Answer: 30
Step-by-step explanation:
The least common multiple of two numbers, or LCM, is the smallest multiple that can divide evenly into both numbers. We can easily find the LCM by finding the primes that multiply into both numbers.
[tex]5=5\\ 6=2*3[/tex]
If there were any in common between the factorization of both numbers, we would only need to count it once. Since there weren't any, the smallest multiple of both numbers would be their product, 30.
Hence, the LCM of 5 and 6 is 30.

how many ten digit numbers have at least two equal digits
Answer:
A ten digit number without any equal digits is a permutation of 0,1,2,3,4,5,6,7,8,9.
Assuming the first digit cannot be zero, there are 9×9! such permutations.
In total there are 9×109 ten digit numbers so you can easily calculate the probability.
