Answer:
the probability that at least one envelope is a yellow envelope is 16/21
Step-by-step explanation:
The probability that at least one envelope is a yellow envelope is P(Y);
P(Y) = 1 - P(Y)'
P(Y)' is the probability that no envelope is a yellow envelope.
Given;
red envelope = 1
blue envelopes = 3
green envelopes = 2
yellow envelopes = 3
Total = 9
Number of non-yellow envelope = 9 -3 = 6
(6 envelope are not yellow)
P(Y)' = P1 × P2 × P3
Since there is no replacement;
P(Y)' = 6/9 × 5/8 × 4/7
P(Y)' = 5/21
From equation 1;
P(Y) = 1 - 5/21
P(Y) = 16/21
the probability that at least one envelope is a yellow envelope is 16/21.
Subtract 363,321 from 778,871. Which gives you 415,550 more geese than crows :)
I would say approx 110ft. I’m not certain.
I hope this helped!
I would appreciate it if you gave me a Thanks and a brainliest (:
It looks like a reflection over the y-axis. There's a formula you can use when doing reflections over the y-axis, (x,y) is going to become (-x, y) thats also the coordinate rule I think.
If you apply that rule to each point you should get the reflected image.
G- (1, 3) then (-x,y) to get (-1,3)
E- (1, 2) then (-x,y) to get (-1, 2)
V- (5, 1) then (-x,y) to get (-5, 1)
X- (3, 3) then (-x,y) to get (-3, 3)
Answer:
121°
Step-by-step explanation:
The angle with measure x is an exterior angle of the triangle.
The angles measuring 90° and 31° are the remote interior angles to the exterior angle.
<em>Theorem:</em>
<em>In a triangle, the measure of an exterior angle equals the sum of the measures of its remote interior angles.</em>
x = 31 + 90
x = 121°
