Answer:
15x
Step-by-step explanation:
9 chairs because 2 to 4 is equal to 1/2 and half of 18 chairs is 9
Answer:
y=5
Step-by-step explanation:
draw a perpendicular line from the directrix passing through the focus, this will be the line of symmetry.
The vertex(h, k) will be located on the line half way between the focus and directrix.
The distance from the focus to the vertex is called the focal length, call it a. The then equation is
(x - h)^2 = 4a(y - k)
the equation can be manipulated to
y = 1/4a(x - h)^2 + k

The conditional probability that a degree is earned by a person whose race is White, given that it is an associate's degree, is 57.14%.
Given that of all postsecondary degrees awarded in the United States, including master's and doctorate degrees, 21% are associate's degrees, 58% are earned by people whose race is White, and 12% are associate's degrees earned by Whites, to determine what is the conditional probability that a degree is earned by a person whose race is White, given that it is an associate's degree, the following calculation should be performed:
- A cross multiplication must be applied to obtain the percentage of whites who have obtained an associate degree.
- 21 = 100
- 12 = X
- 12 x 100/21 = X
- 1200/21 = X
- 57.14 = X
Therefore, the conditional probability that a degree is earned by a person whose race is White, given that it is an associate's degree, is 57.14%.
