The answer is c because you have to divide
Answer with explanation:
The Meaning of the word Random is , selecting instantaneously from a group of Population for the study.
Suppose you are in a room where mathematics students are studying.You selected few week and few quite intelligent among them for a test to check how whole group of maths student is performing in maths.
So, Selecting participants at random will, on average, lead to samples that are...........
Option B.→ Representative of the population from which they were sampled.
<span><span>K = k + 13</span><span>78</span></span>
Cross multiply:
K * 8 = 7 * k + 13
Simplifying
K * 8 = 7 * k + 13
Reorder the terms for easier multiplication:
8K = 7 * k + 13
Reorder the terms:
8K = 7 * 13 + k
8K = 13 * 7 + k * 7
8K = 91 + 7k
Solving
8K = 91 + 7k
Solving for variable 'K'.
Move all terms containing K to the left, all other terms to the right.
Divide each side by '8'.
K = 11.375 + 0.875k
Simplifying
K = 11.375 + 0.875k
there it was hard but i got it
Step-by-step explanation:
I hope you understand.....
6 numbers per cube
3 numbers are less than 4 ( 1, 2 & 3)
so you have a 3/6, reduce to 1/2 probability of rolling a number less than 4 on each cube
2 cubes
so 1/2 * 1/2 = 1/4 probability
