Answer:

C. 11.60 ounces to 12.60 ounces

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

Approximately 68% of the measures are within 1 standard deviation of the mean.

Approximately 95% of the measures are within 2 standard deviations of the mean.

Approximately 99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean 12.10, standard deviation 0.25.

In which range will the amount of water dispensed be found 95% of the time?

By the Empirical Rule, within 2 standard deviations of the mean. So

12.10 - 2*0.25 = 12.10 - 0.5 = 11.60

12.10 + 2*0.25 = 12.10 + 0.5 = 12.6

So the correct answer is given by option C.

W/6 + 5/8 = -1 3/8 Solve the equation
kozerog [31]

Answer:

w = -12

Step-by-step explanation:

w/6 + 5/8 = -1 3/8

Subtract 5/8 from each side

w/6 + 5/8-5/8 = -1 3/8 - 5/8

w/6 = -1 3/5 - 5/8

w/6 = -1 8/8

w/6 = -2

Multiply by 6 on each side

w/6 *6 = -2*6

w = -12

Britta bought some carrots and apples for $24.80. A carrot and an apple cost .90 cents all together. She bought more carrots tha
MrRissso [65]

Answer:

20

Step-by-step explanation:

24.80-6.80=$18   that's what Britta spent on equal number of carrots and apples because $6.80 was spent on extra carrots only.

18/ .90=20 that means she got 20 apples and 20 carrots before she added $6.80 to buy some extra carrots

Thus, the number of apples Britta bought = 20
