Answer:
(b)
Step-by-step explanation:
When two p and q events are independent then, by definition:
P (p and q) = P (p) * P (q)
Then, if q and r are independent events then:
P(q and r) = P(q)*P(r) = 1/4*1/5
P(q and r) = 1/20
P(q and r) = 0.05
In the question that is shown in the attached image, we have two separate urns. The amount of white balls that we take in the first urn does not affect the amount of white balls we could get in the second urn. This means that both events are independent.
In the first ballot box there are 9 balls, 3 white and 6 yellow.
Then the probability of obtaining a white ball from the first ballot box is:
In the second ballot box there are 10 balls, 7 white and 3 yellow.
Then the probability of obtaining a white ball from the second ballot box is:
We want to know the probability of obtaining a white ball in both urns. This is: P( and )
As the events are independent:
P( and ) = P () * P ()
P( and ) =
P( and ) =
Finally the correct option is (b)
Answer:
10.439 Km
Step-by-step explanation:
A- it’s a Pythagorean triple(6, 8, 10)
Answer:
That is a parallelogram so that opposite angles are equal.
10x -27 = 2x + 29
x = 7
and therefore those angles equal 43 degrees each
It is a parallelogram, so
angle V + W +X + Z = 360
we know that angle Y + angle W = 2 * 43 = 86 degrees
angle V + angle X = 360 -86 degrees
angle V + angle X = 274 degrees
angle V = 274 / 2 = 137 degrees
Step-by-step explanation:
Answer: 10mm
Step-by-step explanation: You are going to use the "Pythagorean Theorem" method.
Step 1 :
Equation : a^2+b^2=c^2
plug in your data to the equation given. Then simplify and add.
6^2+8^2=C^2
simplify : 36 + 64 = C^2
simplify : 100 = C^2
Step 2 :
Find what goes into 100 evenly.
100 = 10^2 = (10)(10) = C^2
Step 3:
Find the square root of 10^2 = C^2
10 = c
Last Step :
The length of the unknown leg in the right triangle is 10mm
YAY!!!! you're finished! I hope I explained this so it was easy for you to understand.
