Answer:99.7%

Step-by-step explanation:

The empirical rule states that for a normal distribution, almost all of the

data will fall within three standard deviations of the mean. It states that

1) 68% of the data falls within one standard deviation of the mean.

2) 95% of the data falls within two standard deviations of the mean.

3) 99.7% of the data falls within three standard deviations of the mean.

From the information given, the mean is $70 and the standard deviation is $9. We want to determine the percentage of her phone bill that is between 43% and 97%

Looking at ±3 standard deviations of the mean, it becomes

70 ± 3×9 = 70 ± 27

The value is between 70 - 27 = 43 and 70 + 27 = 97

Therefore, the percentage of her phone bills that is between 43% and 97% is 99.7%

The lifespans of gorillas in a particular zoo are normally distributed. The average gorilla lives 16 years; the

STatiana [176]

Using the Emperical rule:

68% lie with one one standard deviation:

16 + 1.7 , 16-1.7 = 17.7, 14.3

14.3 is part of the 68%.

The remaining 32% of the distribution is outside the range, with half being less than and half being greater than.

32/2 = 16

The probability of living loner than 14.3 Would be 16%

What is the quotient in the polynomial form?

Oxana [17]

First step of a synthetic divison is that we need to carry down the leading coefficient. Here the leading coefficient is 2. So, carry down 2 at the bottom.

Next step is to multiply the divisor -3 with this carry down number 2. So, we have got 3*(-2)= -6 which will place atthe bottom of the next coefficient 4.

Next step is to add this column.

Now repeat the same method again till the last colum.

At the end we have got 0 after the addition. Which means the remainder is 0.

So, the quotient is 2x^2-2x+2.

There are 680 raisins in 8 bags. If each bag has the same number of raisins, how many raisins are in 12 bags?

dmitriy555 [2]

Answer:

1020 raisins

Step-by-step explanation:

The problem tells you the number of raisins is proportional to the number of bags, so there will be "r" raisins in 12 bags:

r/12 = 680/8 = raisins/bag

r = (12/8)(680) = 1020

There will be 1020 raisins in 12 bags.
