Answer:
1/2
Step-by-step explanation:
Not sure but
I am assuming we have 8 integers :
All or (A) = {7,8,9,10,11,12,13,14} = n(A) = 8
Hence, the probability of any one outcome is 1/8.
Therefore, as you can detect, there are 4 numbers that are even numbers which means :
Even or (E) = {8, 10, 12, 14} = n(E) = 4
So, let E imply this occurrence
E x A
= 4 x 1/8
= 4/8
= 1/2
This product involves zero. So, you don't have to bother and compute all the factor, because if you multiply anything by zero you get zero.
Answer:
$250
Step-by-step explanation:
the class width (just choose one of the rows, it could be the same) =>for example:the first row = $(749-500+1) = $250
Answer:
The number 3,822 is divisible by 3 and is not divisible by 9, because the sum of the digits is 3 + 8 + 2 + 2, which equals 15, and 15 is divisible by 3 but not by 9.
Answer:
Final answer is x=4, y=7.
Step-by-step explanation:
Questions says to use the graph to determine the number of solutions the system has. where system of equations are x=4 and y=x+3
any equation of the form x=k is a vertical line crossing x-axis at k.
So x=4 is a vertical line crossing x-axis at 4.
y=x+3 has slope m=1 and y-intercept b=3
So it passes through point (0,3) and for slope m=1, rise 1 up then 1 right to get new point.
Then final graph is given as shown in the picture.
We can see that both lines intersect at point (4,7).
Hence final answer is x=4, y=7.
