Answer:
m=6
Step-by-step explanation:
8(3+7m)=360
24 + 56m = 360
-24 -24
56m = 336
/56 /56
m = 6
1/6 divided by 2
Keep, change, flip
1/6 * 1/2 = 1/12
Answer: 1/12
Answer:
68% of the sample can be expected to fall between 28 and 32 cm
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 30
Standard deviation = 2
What proportion of the sample can be expected to fall between 28 and 32 cm
28 = 30-2
28 is one standard deviation below the mean
32 = 30 + 2
32 is one standard deviation above the mean
By the Empirical Rule, 68% of the sample can be expected to fall between 28 and 32 cm
Answer:
4.428 hours
Step-by-step explanation:
If the learning rate is 0.81, the slope of the learning curve is:
The time it takes to produce the n-th unit is:
If T1 = 8 hours, the time required to produce the seventh unit will be:
It will take roughly 4.428 hours.
