Answer:
1\3
Step-by-step explanation:
Answer:
<em>The events are independent (the outcome of flipping thee coin has no effect on the outcome of rolling the die).</em>
<em>The events are independent (the outcome of flipping thee coin has no effect on the outcome of rolling the die).⇒</em>
<em>The events are independent (the outcome of flipping thee coin has no effect on the outcome of rolling the die).⇒ P(head and an even number) </em>
<em>The events are independent (the outcome of flipping thee coin has no effect on the outcome of rolling the die).⇒ P(head and an even number) = P(head) ×</em><em> P(even number)</em>
<em> P(even number)Assuming a fair coin and a fair die:</em>
<em> P(even number)Assuming a fair coin and a fair die:P(head) </em>
<em> P(even number)Assuming a fair coin and a fair die:P(head) =50%</em>
<em> P(even number)Assuming a fair coin and a fair die:P(head) =50%P(even number) </em>
<em> P(even number)Assuming a fair coin and a fair die:P(head) =50%P(even number) =50%</em>
<em> P(even number)Assuming a fair coin and a fair die:P(head) =50%P(even number) =50% (since half the numbers on a die are even).</em>
<em> P(even number)Assuming a fair coin and a fair die:P(head) =50%P(even number) =50% (since half the numbers on a die are even).P(head and even number) </em>
<em> P(even number)Assuming a fair coin and a fair die:P(head) =50%P(even number) =50% (since half the numbers on a die are even).P(head and even number) =50%×50%</em><em>=25%</em>
Answer:
8 and 14
Step-by-step explanation:
let the 2 numbers be x and y with x > y
We can model the situation using the following 2 equations
x + y = 22 → (1)
3x - y = 34 → (2)
adding the equations term by term will eliminate the term in y
(x + 3x) + (y - y) = (22 + 34)
4x = 56 ( divide both sides by 4 )
x = 14
substitute x = 14 into (1)
14 + y = 22 ⇒ y = 22 - 14 = 8
Answer:
You answer would be option B
Step-by-step explanation:
You would have to open parenthesis/distribute 4 by multiplying it by x and 8 which are inside the parenthesis.
