Answer:
i) is irrational and ii) is rational
Step-by-step explanation:
i) does not keep a consistent pattern. If it was .11011011011.... it would be a rational number, but since it keeps changing its pattern it would be considered irrational. ii) is rational because it has a consistent pattern that doesn't change.
Answer
0.975 is the probability value
Step-by-step explanation:
We start by getting the z score of 86
z-score = (x - mean)/SD
z-score = (86-98)/6 = -12/6 = -2
So we want to find the probability of z greater than or equal to 2
We shall be using the standard normal distribution table here
We have the answer as;
0.975
1 kg= 1000g
threfore 100g=100/1000 kg
=0.1 kg
95p= 1/2 kg ...1/2 kg=0.5 kg
; 0.5=95
0.1=? ; (0.1*95)/0.5
=19p
First, I solve the equation: 5^7+5^6...
I got 93750

The divisibility rules of 6 are:
- It must be divisible by 2
- It must be divisible by 3
So, let's check if 93750 is divisible by 2 first.
It's in even number which automatically means that it is divisible by 2.
No odd numbers are divisible by 2

Now let's check if it is divisible by 3 second.
The divisibility rules of 3 are:
- The digits added must be divisible by 3
So, 9 + 3 + 7 + 5 + 0 = 17
17 is NOT divisible by 3.

Therefore, your equation is not divisible by 6!
X + 1/4x = 15
4/4x + 1/4x = 15
5/4x = 15
5x = 60
x = 12
