Asuume that the distribution in the small sample is representative of the whole. We can first compute the fraction of yellow in the sample:

Y=\frac{y}{total} = \frac{y}{r+y+b+p} = \frac{20}{15+20+12+8}=\frac{20}{55}=\frac{4}{11}

We can tehen use this fractino to compute the expected number of yellow in a sample of 22 total beans:

Y_{22} = 22 \times \frac{4}{11} = 7.999999

There will be about 8 yellow beans.

Answer:

You can expect 8 yellow jelly beans.

Step-by-step explanation:

The ratio of yellow jelly beans to the total amount is:

20 : 55

If you want find the rate of 20 yellow jelly beans to the total amount, you would have to divide:

20 / 55 = 0.36363636 (long series of number continues)

Now that you have the rate of yellow jelly beans, you can use that rate to find the estimated amount of yellow jelly beans in a total of 22:

0.36363636 * 22 = 8

Hope this helped :))

0.046666666666667 Rounded to the nearest cent
svp [43]

Answer: 5 Cents.

Step-by-step explanation: Mate, if its 0.046666666666 (repeating,) just go from the four, then to the left. since your number is six, and its higher than five (if its below five, keep it the same, if its above five, raise the number you went off of.) so it gets rounded up to 0.05. Which i believe if 5 cents, according to the question.

Brandy set her watch 4 seconds behind and it falls behind another 1 second every day. How many days had it been since brandy las
kari74 [83]

Answer:

18 days

Step-by-step explanation:

Let x represent number of days.

We have been given that Brandy's watch falls 1 second every day. So Brandy's watch will fall 1x seconds behind in x days.

We are also told that Brandy set her watch 4 seconds behind, so Brady's watch will be behind by total x+4 seconds in x days.

Since Brady's watch is 22 seconds behind, so we will equate x+4 by 22 to solve for x as:

x+4=22

x+4-4=22-4

x=18

Therefore, Brandy set her watch 18 days ago.
