how many ten digit numbers have at least two equal digits

Answers

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.

Permutation of 0,1,2,3,4,5,6,7,8,9

There are x students in Mrs. Schwartz's third-grade class. One fewer than half the students have brown eyes. Six fewer children have blue eyes than have brown eyes. The rest of the students have green eyes. How many students have green eyes?


F. 8
E. 7
G. x/2-7
H. x - 8

Answers

Brown Eyes: 1/2x - 1
Blue Eyes: 1/2x-6

Let the students who have green eyes be y.

1/2x-1+1/2x-6= x-y (Because the RHS is the students with brown and blue eyes and hence x-y on the LHS)
x-7=x-y
-y=-7
y=7

Therefore 7 students have green eyes.

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.

Answers

the mean is 5 since you do 500 divided by 100 which is 5

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

What is scale factor of the dilation?
Can scale factors be rationals numbers?
Please explain in the most detailed way you can.

Answers

1) How much larger or smaller the image will be depends on the scale factor in a mathematical object's dilatation (compared to the original object). When the scaling factor's absolute value exceeds 1, an expansion takes place.

2) No. scale factors can’t be rational numbers. Scaling up always involves a scale factor larger than 1. Let's put this in the formula, which makes it: 15 5 = 3, for instance, if the larger figure's dimension is 15 and the smaller one's is 5. As a result, it is clear that the scale factor is higher than 1.

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?

Answers

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.

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.

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.

Answers

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.)
