A number line can be used to find the difference because you can count from 28 to 34 and the number you get will be your answer.
Answer:
16%
Step-by-step explanation:
The mean is 25, and the standard deviation is 1.
26 is 1 standard deviation above the mean.
According to the empirical rule, 68% of the population is between -1 and +1 standard deviations. That means that 32% is less than -1 or greater than +1 standard deviations. So half of that, or 16%, is greater than +1 standard deviations.
Answer:
3,781
Step-by-step explanation:
To solve this problem, we will find the area of the whole circle and use that to find teh area of the 60º section.
First, recognize the formula for the area of a circle:
A = 3.14
In this scenario, the radius (<em>r</em>) is 85 feet:
A = 3.14(85
A circle is 360º and we only require the area of 60º. 360º / 60º = 6 so we will divide by 6:
A = 
Finally, we will simplify and round:
A = 3,781
The most common scenario was the low-fuel landing. It was there in 25 % of the tests. The number of tests was 25+115=140 tests (adding up the failed and passed test.
So to find our how many were trained in the most common scenario, we have to calculate25% of 140.
25/100*140=(i calculate frist 25/100. I divide both by 25, we have 1/4)1/4*140 = In order to calculate this, we need to divide 140/4. This is:
35____140:4 12 20 20 ==
so the correct answer is 35.
