Answer:
a
Mutually exclusive
b
Not Mutually exclusive
c
Not Mutually exclusive
d
Not Mutually exclusive
Step-by-step explanation:
From the question we are told that
The number of bolt is n = 12
The event that all the bolt are torqued correctly is A
The event that the 3rd bolt is not torqued correctly is B
The event that exactly one bolt is not torqued correctly is C
The event that the [tex]4^{th}[/tex] and [tex]8^{th}[/tex] are torqued correctly is D
Generally for an event to be mutually exclusive it means that both event can not occur at the same time
Considering a
The A and B are mutually exclusive because they can not occur at the same time
Considering b
The event B and D are not mutually exclusive because they can occur at the same time
Considering c
Event C and D are not mutually exclusive because they can occur at the same time
Considering d
Event B and C are not mutually exclusive because they can occur at the same time

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Total pages= 230
Percentage of reading = 70%
So, number of Pages Tim reads
= 70 /100 x 230
= 161 pages
Hence, number of pages left = 230- 161 = 69 pages

We have to find out what the shaded regions represent. We can count up ten rectangles in total, and three of them are shaded. We take the amount of shaded rectangles over the total amount to get [tex]\tt \frac{3}{10}[/tex] as a fraction, and 0.3 as a decimal.
[tex]\tt First~option:[/tex]
The first choice is 0.300. The zeroes at the end of the number do not mean anything, so we can simplify it to 0.3. 0.3 is equal to 0.3, so this is not the answer.
[tex]\tt Second~ option:[/tex]
The second choice is 0.30. Again, we can simplify it to 0.3. We can see that it is equivalent to 0.3, so this is not the answer, either.
[tex]\tt Third~option:[/tex]
Our third choice is 0.3. 0.3 = 0.3, so this is not our answer either.
[tex]\tt Fourth ~option:[/tex]
Our final choice is 0.030. Take out the last zero to get 0.03. 0.03 is equal to [tex]\tt \frac{3}{100}[/tex], so this is our answer, since it is not 0.3.

Divide polynomials using long division
(13q–91)÷(q–7)
Answer:
13
Step-by-step explanation:
q-7 can go into 13q-91 thirteen times.
Set up the long division sign with the q-7 on the outside and the 13q-91 inside.
Then, notice that to get to 13, you multiply the q and 7 by 13. This gets both terms to 13q and 91, which cancel out the numbers inside the long division sign.

Plug in a to verify it's a solution.
Substitute: 3(5 + 3) + 6 = 30Add: 3(8) + 6 = 30Multiply: 24 + 6 = 30Add: 30 = 3010.2 is 21.25% of what number?
Answer: 48
Step-by-step explanation: Using proportions
48 is the number whose 21.5 percent is 10.2 .
What is percentage?
A percentage is a number or ratio that can be expressed as a fraction of 100.
How to convert a percentage into a number?Divide the given percentage by hundred to convert it into a number.
Let x be a number whose 21.5% is 10.2.
Therefore,
[tex]\frac{21.25}{100} (x) = 10.2[/tex]
⇒ [tex]21.25x = 10.2(100)[/tex]
⇒[tex]21.25x = 1020[/tex]
⇒[tex]x = \frac{1020}{21.25}[/tex]
⇒[tex]x = 48[/tex]
Hence, 48 is the number whose 21.5 percent is 10.2.
