Answer:
Event 2, Event 3, Event 4, Event 1
Step-by-step explanation:
The probability of Event 2 occurring is 0/12(0%) as there are no red marbles in the bag.
The probability of Event 3 occurring is 13/20(65%) as you will get an orange marble from Bag B 13 out of 20 times.
The probability of Event 4 occurring is 9/12(75%) as you will get a yellow marble from Bag A 9 out of 12 times.
The probability of Event 1 occurring is 20/20(100%); therefore you will always get either a yellow or an orange marble from Bag B.
Answer:
Quotient = a²+ 4a- 2
Step-by-step explanation:
(8a3+31a2-20a-5)/(8a-1)
=
<u> a² +4a-2 ⇒ quotient</u>
(8a-1)√(8a3+31a2-20a-5)
8a²- a² ⇒ Multiplying (8a-1) by a²
<u> - + </u> ⇒ Changing signs
32a²- 20a- 5
32a²- 4a ⇒ Multiplying (8a-1) by 4a
<u> - + </u> ⇒Changing signs
-16a -5
- 16a +2 ⇒ Multiplying (8a-1) by -2
<u> + - ⇒</u> Changing signs
-7 ⇒ Remainder
We follow the steps of simple division to get the quotient which is a²+ 4a- 2
We multiply (8a-1) by factors such as a², +4a and -2 to get the same terms as given in the dividend.
Answer:
As a proper fraction - 39/51 = 13/17
As a decimal number: 39/51 ≈ 0.76
As a percentage: 39/51 ≈ 76.47%
Step-by-step explanation:
Calculate the greatest (highest) common factor (divisor), gcf (gcd).
13/17 =
13 ÷ 17 =
0.764705882353 ≈
0.76
By precentage
0.764705882353 =
0.764705882353 × 100/100 =
76.470588235294/100 =
76.470588235294% ≈
76.47%
Answer:
6
Step-by-step explanation:
Correct formula is y = kx, where k is the "constant of proportionality."
If y = 9 when x = 2, then 9 = k(2), or k = 9/2.
Then y = (9/2)x.
If x = 3, y = (9/2)(3) = 27/2 (answer)
