X=.8(50)
x=40
Therefore 40 is 80% of 50.
Hope this helps!
(Also the formula I used is: part = percent * whole)

There are 1,023 M&M's in a bag. Out of 1,023 M&M's, 132 M&M's are blue, 69 are green, 68 are brown, 63 are olive, 62

lesantik [10]

The probability that the person pulls 1 blue M&M given that one is only allowed to pull 5 random M&M's per day will be 0.6450.

<h3>How to calculate probability?</h3>

From the information given, there are 1,023 M&M's in a bag and out of 1,023 M&M's, 132 M&M's are blue.

Therefore, the probability of getting a blue M&M will be:

= 132/1023

= 0.1290

Therefore, since the person is given the chance to pull 5 random M&M's per day, the probability will be:

= 0.1290 × 5

= 0.6450

Which is an equivalent form of the expression 1800(1.2)^-t

ololo11 [35]

Answer:

1800(5/6)^t

Step-by-step explanation:

I don't see any answer choices, but this would be another form if it is listed. The negative exponent means that you get the reciprocal of the fraction (in this case 1.2). This turns 1.2 into (1/1.2), which is equivalent to 5/6.

Four possibilities have probabilities 0.4, 0.2, 0.2 and 0.2 and values $40, $30, $20, and $10 respectively. The expected value i

LiRa [457]

Answer:

b. $28

Step-by-step explanation:

We have these following probabilities:

0.4 = 40% probability of $40

0.2 = 20% probability of $30

0.2 = 20% probability of $20

0.2 = 20% probability of $10

The expected value is:

We multiply each value by its probability. So

$E = 0.4*40 + 0.2*30 + 0.2*20 + 0.2*10 = 28$

So the correct answer is:

b. $28
