Answer:
First break apart 923 into 900+20+3 then do 9 times 900,9 times 20 and 9 times 3. Then add all the products together to get your answer.
Step-by-step explanation:
Answer:
P(T) = 1/20 = 0.05
The probability of randomly selecting an umbrella and a shaving kit in that order is 0.05
Step-by-step explanation:
The probability of randomly selecting an umbrella and a shaving kit in that order.
P(T) = Probability of selecting umbrella first P(U) × probability of selecting shaving kit second P(S)
P(U) = 1/5 (1 umbrella out of five possible gifts)
P(S) = 1/4 (1 shaving kit out of four remaining possible gifts)
P(T) = 1/5 × 1/4
P(T) = 1/20 = 0.05
Yes because simplified 9/15 equals 3/5 and 6/10 also equals 3/5
so... that's how much an internal angle is
now, subtract that from 180 and you get the angle outside, in the picture
subtract that outside angle twice from 180, and you get angle "2"
because angle 2 is in the same triangle as those two outside angles, and all internal angles in a triangle is 180, thus 180 - (those two angles) is angle "2"
Answer:
x = - 1, y = 4
Step-by-step explanation:
A. We are going to use elimination method because we have +2y and -2y, and when we add these equations +2y and -2y are going to be eliminated.
B.
x + 2y = 7
<u>+ 3x - 2y = -11</u>
4x = - 4
x = - 1
x + 2y = 7
-1 + 2y = 7
2y = 8
y = 4
