7+10+12= 29
232-29= 203
7+10+12+203= 232
I hope this helps ^-^
How many levels are in the game? You would take that number and multiply it by 0.72 to find 72% of it.
Answer:
y = x^2 +2x -35
Step-by-step explanation:
Multiply the binomials. The distributive property is helpful.
y = x(x -5) +7(x -5) . . . . the terms of the first binomial multiplied by the second
= x^2 -5x +7x -35 . . . . eliminate parenthses
y = x^2 +2x -35 . . . . . . collect terms
Answer:
I am 100% sure its 4.03 x 10^7
Step-by-step explanation:
A standard deviation is 2500 miles, so the range of 25,000 to 37,500 is 2 standard deviations below, and 3 standard deviation above the mean of 30,000.
We aren't assuming anything about the distribution, but we sort of have to assume a normal distribution in order to answer. When you don't know anything about a distribution, this is generally what you do.
The general rule for standard deviations is:
+/- 1 SD: +/- 34% of population, for a total of 68%
+/- 2 SD: Another 14% in either direction, for a total of 96% of population.
+/- 3 SD, Another 2% in either direction, which pretty much captures the entire distribution (4 standard deviations from the mean is incredibly rare/unlikely)
We have a range of +/- 1 SD, so we know that 68% percent o the tire 'population' is captured in the range. We also have one more standard deviation in both directions, so we add 28% to this number to get 96% of the population. We have a third standard deviation above the mean, so we add another 2% to arrive at 98% of the population.
Answer is 98% of all such tires.
