<span>At least 75% of the data will fall within 2 standard deviations of the mean.
This is tricky problem. Usually when you're dealing with standard deviation, you have a bell curve, or something close to a bell curve and for such a data distribution, there will be approximately 95% of the data within 2 standard deviations of the mean. But if you don't know that you have a bell curve, you have to fall back to Chebyshev’s Theorem, which states that at least 75% of the data points will fall within 2 standard deviations of the mean for any set of numbers.</span>
Answer:
0.
Step-by-step explanation:
Fair dice are dice that have 6 sides, and the probability of rolling a side is the same as rolling another.
Since each die has 6 sides, the most you can get from the two dice are 6 + 6 = 12. Therefore, getting a 13 is impossible. So, there is a probability of 0.
Hope this helps!
Answer:
12 squares
Step-by-step explanation:
Data provided:
Dimension of the rectangle = 30 × 40
Area of the rectangle = 30 × 40 = 1200
Dimension of the area to be divided = 10 × 10
Thus,
Area of the square to be divided into = 100
Therefore,
The number of square in which it can be divided
= 
= 
= 12
Hence,
It can be divided in 12 squares
Answer:
Step-by-step explanation:
a)/Let x represent the amount of money earned by the World Issues club for all their fundraising activities this year.
Let y represent the revenue generated for the foundation.
b) The World Issues club has decided to donate 60% of all their fundraising activities this year to Stephen Lewis Foundation. Therefore, an equation that will determine the amount of money the foundation will receive is
60/100 × x = y
0.6x = y
