Hi, What is the lowest positive integer greater than 1, which when divided by 5 or 8 leaves a remainder of 1

1 answer:

3 0

Very interesting question!

Let's try to get something that would work for just 5 for now.
Any of these numbers would leave a remainder of 1 when divided by just 5:
6, 11, 16, 21, 26, 31, 36, 41, 46, 51, 56, 61, 66, 71, 76, 81, 86, ...
Notice that they all look like 5*(something) + 1. Basically, they are all multiples of 5 plus 1.

Let's see what would work for just 8:
9, 17, 25, 33, 41, 49, 57, 65, 73, 81, 89, ...

Are there any matches... AHA! It's 81. This is the lowest positive integer greater than 1 that follows the rule for both 5 and 8.

Amelie has a spinner divided into ninths equal sections that are labeled 1 through 9. she wants to compare the theoretical proba

VMariaS [17]

The theoretical probability = $\dfrac{5}{9}$ , The experimental probability = $\dfrac{5}{12}$

<h3>What is experimental probability?</h3>

The experimental probability of an event occurring is the number of times that it occurred when the experiment was conducted as a fraction of the total number of times the experiment was conducted.

The sample will be ={1,2,3,4,5,6,7,8,9}=9

favourable outcomes={1,3,5,7,9,}=5

The theoretical probability of spinning and odd number = $\dfrac{5}{9}$

As she spends the spinner 12 times

The experimental probability = $\dfrac{5}{12}$

Hence the theoretical probability = $\dfrac{5}{9}$ , The experimental probability = $\dfrac{5}{12}$

Solve the system of equations using elimination.

Andrej [43]

Answer:

{x = 3, y = 9 thus Answer A is correct

Step-by-step explanation:

{5 y - 7 x = 24 | (equation 1)

{5 y - 9 x = 18 | (equation 2)

Swap equation 1 with equation 2:

{-(9 x) + 5 y = 18 | (equation 1)

{-(7 x) + 5 y = 24 | (equation 2)

Subtract 7/9 × (equation 1) from equation 2:

{-(9 x) + 5 y = 18 | (equation 1)

{0 x+(10 y)/9 = 10 | (equation 2)

Multiply equation 2 by 9/10:

{-(9 x) + 5 y = 18 | (equation 1)

{0 x+y = 9 | (equation 2)

Subtract 5 × (equation 2) from equation 1:

{-(9 x)+0 y = -27 | (equation 1)

{0 x+y = 9 | (equation 2)

Divide equation 1 by -9:

{x+0 y = 3 | (equation 1)

{0 x+y = 9 | (equation 2)

Collect results:

Answer: {x = 3, y = 9
