What does if mean?
Step-by-step explanation:
if means not true but what if it was a question like that or a thing you ask your friends
Answer:
6
Step-by-step explanation:
3(x+2) = 4x
3x + 6 = 4x <- you times the x and 2 that is inside of the parentheses by the 3 that is on the outside
3x - 3x + 6 = 4x - 3x <- you have to subtract the 3x from the left side and you have to do the same on the right so you can get the numbers alone.
6 = x
Answer:
Slope-intercept
y = 3/4(x) - 7
Point slope
y -5= 3/4(x - 16)
Step-by-step explanation:
In slope-intercept
We have the general slope intercept as;
y = mx + b
where m is the slope and b is the y-intercept
in this case, m = 3/4 and b = -7
So we have;
y = 3/4(x) - 7
In point-slope
we have the general form as;
y-y1 = m(x-x1)
So what we have is as follows;
y -5= 3/4(x - 16)
Where we have (x1,y1) = (16,5)
The mean of this discrete random variable is 7.96
<em><u>Solution:</u></em>
Given that,
x 4 6 9 11 15
P(x) 0.20 0.34 0.15 0.22 0.09
<u><em>Mean is given as:</em></u>
![\mu_{x}=\sum[x \times P(x)]](https://tex.z-dn.net/?f=%5Cmu_%7Bx%7D%3D%5Csum%5Bx%20%5Ctimes%20P%28x%29%5D)
Therefore,
Thus, mean of this discrete random variable is 7.96
Answer:
the first one
Step-by-step explanation:
m=10 n=1
10+1 =11
10 x 1=10
