<u>The given expressions 7+ 7x ; 7 x + 1/7 are not equivalent or equal </u>
<u>to each other </u>
<u />
<u>Step-by-step explanation:</u>
Let us firstly assume that 7 + 7x is equivalent ( to 7(x + 1/7) so that means
7 + 7x = 7(x + 1/7)
7 + 7x = 7x + 7(1/7)
7 + 7x = 7x + 1
7x + 7 = 7x + 1
Now, subtracting 7x from both sides, we get:
7x - 7x + 7 = 7x - 7x + 1
(7 - 7)x + 7 = (7 - 7)x + 1
(0)x + 7 = (0)x + 1 thus their occurs a false statement:
7 = 1 ( we know, 7 >1)
Thus we can say that
<u>7 + 7x is NOT equivalent to 7(x + 1/7)</u>
So for example 50 65 68 72 74 78 80 82 83 84 90 91 92 92 92 92 93 94 95 97 98 98 99 99 100 100.
if we use that we could make this.

9 0 1 2 2 2 2 3 4 5 7 8 8 9 9

Answer:
Step-by-step explanation:
Given
--- proportion that have very little confidence
--- sample
Required
Determine the probability that exactly 5 have very little confidence
This question will be solved using binomial probability:
In this case: x = 5.
So, we have:
Number two is thirty weeks
