Answer:
415$
Step-by-step explanation:
This might seem a bit confusing, and the best thing you can do is simplfy this and pick out all the important information. Here is what I gathered:
So, we know we need 200$.
We also need 115$.
Then we need 100$..
To find how much money we need in total, lets add these all up:
200+115
=
315
315+100
=
415
So the total money we need is 415!
Hope this helps!
Answer:
(8a)⁻¹⁸
1 / (8a)¹⁸
Step-by-step explanation:
(((8a)^6a)^4/4a))^-3
((8a)^6a*4/4a)^-3
((8a)^6)^-3
(8a)^6*(-3)
(8a)⁻¹⁸
1 / (8a)¹⁸
If the probability of independent event A is 0.5, then P(A|B) will be 0.5. Then the correct option is B.
<h3>Which pair of events are called independent events?</h3>
When one event's occurrence or non-occurrence doesn't affect occurrence or non-occurrence of other event, then such events are called independent events.
Symbolically, we have:
Two events A and B are said to be independent iff we have:
P(A ∩ B) = P(A)P(B)
Comparing it with chain rule will give
P(A|B) = P(A)
P(B|A) = P(B)
Suppose A and B are dependent events.
If P(A) = 0.5
Then P(A|B) will be
P(A|B) = P(A)
P(A|B) = 0.5
Then the correct option is B.

The required number which when decreased by 8 is divisible by 21, 27, 33, and 55 is 10403.
We need to find the smallest number which when decreased by 8 is divisible by 21, 27, 33, and 55.
<h3>What is LCM?</h3>
The least common multiple is also known as LCM (or) the lowest common multiple in math. The least common multiple of two or more numbers is the smallest number among all common multiples of the given numbers.
We find the LCM of 21, 27, 33, and 55.
3 | 21 27 33 55
3 | 7 9 11 55
3 | 7 3 11 55
7 | 7 1 11 55
5 | 1 1 11 55
11 | 1 1 11 11
| 1 1 1 1
When decreased by 8, we have to add 8 in the LCM of the numbers.
That is 10395+8=10403
Therefore, the required number when decreased by 8 is divisible by 21, 27, 33, and 55 is 10403.

Well, let's discover how many times 7 goes into 126 first.
7 x 11 = 77
7 x 12 = 84
7 x 13 = 91
7 x 14 = 98
7 x 15 = 105
7 x 16 = 112
7 x 17 = 119
7 x 18 = 126
Well, 7 goes into 126 - 18 times - therefore the quotient is 18. The use of the distributive property wouldn't be necessary.
Nevertheless, you could say that:
* I've used the distributive property above.
