Answer:
P = 0.000000028514
Step-by-step explanation:
First we are going to calculate the probability of correctly choosing exactly 4 of the winning numbers.
Remember that the probability of an event can be calculated thus:

The favorable cases resulting from choosing 4 numbers of the set of 5 winning numbers from the upper section.
The favorable cases can be calculated with a combinatorial thus:

and the total cases are:

Then the probability is:

and the probability of correctly choosing the Mega Ball number is:
= 0.0285714
And how both events are independent the probability of correctly choosing exactly 4 of the winning numbers and the Mega Ball number is:
P = (0.000000998)(0.0285714)
P = 0.000000028514
Answer:
d
Step-by-step explanation:
X= -4
Y= 8
I would do an explanation but there’s too many parts and it’s very long and most likely complicated to understand also, but yeah
Answer:
B.(3,2)
Step-by-step explanation:
Point translated from A(1,2) to B(4,4).
This means that for x, we add 3 units(4 - 1 = 3), while for y, we add two units(4 - 2 = 2).
If a point C at (0,0) is translated in the same way, what will be its new endpoints?
0 + 3 = 3
0 + 2 = 2
So
B.(3,2)
Answer:
60
Step-by-step explanation:
To find the mean;
add up the data
(50+60+60+70) =240
Then divide by the number of data points
240/4 = 60
The mean is 60
