C
Step-by-step explanation:
Answer:
19.37.
Step-by-step explanation:
Integrating the function we get
x^4/4 - 5x^3/3 + x^2 + 8x
Area under the curve from x = -1 to x = 0
= (-1)^4/4 - 5(-1)^3/3 + (-1)^2 - 8
= 5.083
In a similar way we calculate area from 0 to 2
this = 10.667.
Total = 15.75.
Now we subtract 12.13 to get the area from x = 2 to x =p.
= 15.75 - 12.13 = 3.62
So total shaded area = 15.75 + 3.62
= 19.37.
Answer is From all those aforementioned, the true statement is: Thanh’s grade is 2.5 standard deviations below the mean of the test grades.
explanation
The z scores are standard deviations. If, for example, a tool returns a z score of +2.5, it means that the result is a standard deviation of 2.5. Very high or very low (negative) z scores associated
with very low p values are at the ends of the normal distribution.
This is how you do it!
So, There is a ratio of 1:2 for the orange to green.
This means that e can write an equation like this:
Let x be the orange picks
x + 2x = 12
3x = 12
x = 4
This means that there are 4 orange picks, and also 8 green picks
Now we can check that by simplifying the ratio --> 4:8 = 1:2
Therefore, your answer would be 8 green picks
Hope this helped!
