Answer:
Step-by-step explanation:
Let the probability of getting employed after graduated within a year be P(A)
and the probability of buying a car within a year be P(B)
Given that:
The probability of getting employed after graduated within a year = 90% = 0.9
Then; Let that be P(A)
The probability of getting employed and buying a car within a year = 72% = 0.72.
Then; Let that be P(A∩ B).
The probability that a college student will get both events is P(B/A)
P(B/A) = 0.80
Answer:
(-1, -1/2)
Step-by-step explanation:
To find the x coordinate of the midpoint, add the x coordinates and divide by 2
( -11+9)/2 = -2/2 = -1
To find the y coordinate of the midpoint, add the y coordinates and divide by 2
(0+-1)/2 = -1/2
(-1, -1/2)
3,000 = 3 x 10 x 10 x 10 = 3 * 10^3
--------------
10^3 * 3 * (640)
= 10^3 * 3 * (600 + 40)
= 10^3 * (1800 + 120)
= 10^3 * 1920
= 1,920,000
Answer:
Interval positive and negative
The positive regions of a function are those intervals where the function is above the x-axis. It is where the y-values are positive (not zero). The negative regions of a function are those intervals where the function is below the x-axis. ... y-values that are on the x-axis are neither positive nor negative.
Step-by-step explanation:
Property: In every triangle the median is divided by the centroid (intersection point of the medians) in a 2:1 ratio, the shorter toward the midpoint of the side. We use this property in all of the above:
1. PD = 15. Since we know CP=30, PD is half of that, i.e., 15
2. FP = 13. Since BF = 39, and we know that FP is 1/3 of BF (see property stated above), FP = 13.
3. BP = 26. Following (2), BF is partitioned by FP and BP as 1:2. Hence BP is 2/3 of FP, or 26.
4. CD=45. In (1) we calculated PD=15 and we are given CP=30, so CD=45.
5. PA=36. We are given EP=18, which is 1/3 of length EA, so PA = 2*EP = 36.
6. EA=54. EA=EP+PA = 18+36=54
