Step-by-step explanation:
Step 3 is incorrect because it shows an incorrect ratio for the slope.
The 5 people can seat in a row in 5! ways
But we need to exclude the ways <span>that ann and bob are seated next to each other which is = 4! * 2!
</span>
So, the number of <span>ways can ann, bob, chuck, don and ed be seated in a row such that ann and bob are not seated next to each other = 5! - 4! * 2! = 72
</span>
<span>=====================================================
</span>
<span>Another solution:
</span>
<span>If ann seated in one of the ends, the number of ways = 3*2
</span>
<span>If ann didn't seat in one of the ends , the number of ways = 2*3
</span>
So, the total number of <span>ways that can <span>ann, bob be seated = 3*2 + 2*3 = 12
</span></span>
The remaining persons can seat with a number of ways = 3! = 6
So, the total ways that the five persons can seat = 12*6 = 72
Answer:
The expressions a(8x+7) and 4x + 3.5 are equivalent
Therefore, according to the above problem the equation is :---
By comparing the term, we get
and,
<h3>The value of "a" is <u>1/2</u>.</h3>
Answer:
so it need 6 m
Step-by-step explanation:
= mgh
height will be one quarter
then compression is half so it is 6m far
