Answer:
Step-by-step explanation:
I believe the answer is going to be 830 or higher. Kaleys score needs to be 2 standard deviations above the mean and one standard deviation is 40 so 40*2=80. The mean is 750 + 80 = 830 is what she would need to get in.
Answer:
0.015
Step-by-step explanation:
The probability two independent events take place is the product of their individual probabilities.
p(shoes & book) = p(shoes) * p(book) = 0.15 * 0.10 = 0.015
Let's imagine all the tickets were for children.
The fees collected would've been 342 x 1.25 = $427.5
That is 1337 - 427.5 = $909.5 less than the actual fees.
Everytime we switch 1 children ticket to an adult ticket, the gap goes down 6.60 - 1.25 = 5.35
For example, if 341 tickets were children tickets, and 1 is adult, the gap go from 909.5 to 904.15.
We do this until the gap becomes 0... So, there are 909.5 : 5.35 = 170 adult tickets
And there are 342 - 170 = 172 children tickets
Recheck : 172 x 1.25 + 170 x 6.6 = 215 + 1122 = 1337.
Answer:
Step-by-step explanation:
Equation of the line perpendicular to f(x) that passes through origin:
Intersection point:
, 
Triangle formed with vertex A (0,9), O(0,0), and C (27/13, 51/26).
The height of the triangle is 27/13 with respect to the base OA
Now, the leftover is just applying the formula to find the area of the triangle.
