1. y=6
2. y=-12
Step-by-step explanation:
<u>1) If y varies inversely as x, and y=3 as x = -2, find y for the x value of -1.</u>
It is given that
y varies inversely as x
IT will be written as:
y∝1/x
Removing the proportionality symbol
y=k/x
Given
y=3 , x=-2
Putting the values
3=k/-2
k=3*-2 = -6
The equation will be:
y=-6/x
So,
When x=-1
<u>2) If y varies directly as x, and y=15 as x=-3, find y for the x value of 4</u>
y is directly proportional to x
y∝x
y=kx
Given
y=15, x=-3
Putting the values
Hence,
1. y=6
2. y=-12

Quick Answer: 1/12
P(H) * P(2) = 1/2 * 1/6 = 1/12
What this means is that is you flip the coin 12 times and follow that with a role of 1 die, a head and a 2 out to come up once. That does not mean it will. It only means that it should.
Answer:
Sammy is expected to lose $1.39 on average per roll
Step-by-step explanation:
Since Sammy is rolling two six-sided cubes, the number of possible outcomes is given by:
6 x 6 =36
Out of those 36 outcomes, only two would result in a sum of 3, rolling a 1 and 2 or a 2 and a 1. Therefore, the probability of winning (P(W)) and the probability of losing (P(L)) are:
The expected value is defined as the sum of the product of the likelihood of each event by its payout:
Sammy is expected to lose $1.39 on average per roll.
