, . Correct option D) sin y° .
<u>Step-by-step explanation:</u>
Here we have , The figure below shows a right triangle: A right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units. The angle b . We need to find What is r ÷ q equal to . Let's find out :
We have the following dimensions for the right angle triangle as
Now, ..........(1)
but , ...........(2)
Putting value of equation (1) in equation (2) we get:
⇒
⇒
Therefore , . Correct option D) sin y° .
Answer:
- x = 4
Step-by-step explanation:
First, we add 16 and 28
Now we have to solve for x
We know we have to do parenthesis first so
Then we divided both sides by 11
To find the Prime Factorisation of 84 we have to divide 84 by the smallest prime number which is 2
So
Since 42 is an even number we can still divide it by 2
So
Now we can divide 21 by the 2nd smallest prime number which is 3
So
So the prime factors of 84 would be or
Answer:
0.0455
Step-by-step explanation:
<u>The formula for calculator probability is
</u>
# of favorable outcomes / # of possible outcomes
<u>The total number of marbles in the bag: </u>
7+3+2=12
<u>Probability of the first marble being blue:</u>
3/12
<u>Probability of the second marble being blue:</u>
2/11 -- 2 because only 2 blue marbles left after drawing the first one out, 11 because after taking the first marble out, we have 11 marbles left in the bag
<u>Formula for both events happening:</u>
p(A and B) = p(A) * p(B)
In this problem,
A = first one blue
B = second one blue
<u>Probability that if two marbles are drawn out of the bag, both are blue:</u>
3/12 x 2/11 = 0.045454
<u>Rounded answer:</u>
0.0455 (or 4.55%)
