Y = -4x/5 + 13/5 would be the answer to 4x+5y=13
Answer :
x = - 12 for y = - 4
Step-by-step explanation:
Given as y = - 6 when x = - 14
write in equation form
I.e y = x + c
Put x and y values ,
So, c = y - x
c = - 6 + 14 = 8
Now when y = - 4 and c = 8 ,
So, from eq x = y - c
∴ x = - 4 - 8 = - 12 Answer
Using the <u>arrangements and the probability concept</u>, it is found that there is a 0.75 = 75% probability that the number formed is not divisible by 4.
- A probability is the <u>number of desired outcomes divided by the number of total outcomes</u>.
- The number of possible arrangements of n elements is given by

In this problem, there are 4 elements, hence
.
A number is a multiple of 4 if the <u>number composed by it's last 2 digits are multiples of 4</u>.
- Hence, the possible options for the last 2 digits are: 56, 68, 76.
- For each of them, there are
options for the first 2 digits, hence, there will be 2 x 3 = 6 multiples of 4.
The other 18 numbers formed are not divisible by 4, hence:

0.75 = 75% probability that the number formed is not divisible by 4.
