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.
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
The answer is B. -32 this is a really easy question
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
