Answer: 70 meters.
Step-by-step explanation:
Observe the figure attached.
The distance between the walls is:
<em />
Both triangles are right triangles. Therefore, you can calculate the distance between the walls as following:
- Calculate the distance AD:
- Calculate the distance AE:
Therefore the distance between the walls is:
Answer:
In a normal distribution, 50 percent of the data are above the mean, and 50 percent of the data are below the mean. Similarly, 68 percent of of all data points are within 1 standard deviation of the mean, 95 percent of all data points are within 2 standard deviations of the mean, and 99.7 percent are within 3 standard deviations of the mean.
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.
Also:
The normal distribution is symmetric, which means that 50% of the data is above the mean and 50% is below.
Then:
In a normal distribution, 50 percent of the data are above the mean, and 50 percent of the data are below the mean. Similarly, 68 percent of of all data points are within 1 standard deviation of the mean, 95 percent of all data points are within 2 standard deviations of the mean, and 99.7 percent are within 3 standard deviations of the mean.
Answer:
130 mg
Step-by-step explanation:
As the statement indicates that the daily recommended amount of calcium is 1,000 mg and that Velveeta contains 13% of that, you have to calculate the 13% of 1,000 to find the answer:
1,000*13%=130
According to this, there are 130 mg of calcium in one serving of Velveeta.
