-(1.5, -3)
think of the y axis intercepting the x axis at coordinates (0,0)
-they then said their point is 1.5 left of the y axis
-now all you have to do is to find another x value of that same distance (x,y)
Answer: Score is 629
Step-by-step explanation: z value for P(x > 0,90) is 1,29
Average x is 500 and deviation is 100. Value of score p is solved from
z = (p - x) / s p = s·z· + x = 129 + 500 = 629
If you multiply 2/3 by a product less then 1 you will get a product that is less then 2/3

Answer:
0.1875
Step-by-step explanation:
Let A be the event that class two has been chosen . So the probability of A would be P (A) = 1/2= 0.5
Now class two has 9 girls out of total 24 students . So the probability of chosing the girl would be= P (B=) 9/24= 0.375
So the probability that Classroom #2 was chosen at random, given that a girl was chosen is given by = P(A) . P(B)= 0.5 * 0.375= 0.1875
Another way of finding the probability that Classroom #2 was chosen at random, given that a girl was chosen is by drawing a tree diagram.
P (1/2) Class 1 ------------------------5 boys
-------------------------11 girls (11/16)
P (1/2) Class 2 -------------------------15 boys
-----------------------9 girls P (9/24) Class 2 was chosen (0.5) *9/24
