Answer: 0.20
Step-by-step explanation:
The given probability distribution of number of televisions per household in a small town:
x 0 1 2 3
P(x) 0.05 0.15 0.25 0.55
To find : The probability of randomly selecting a household that has one or two televisions ( in both parts a. and b.).
The computations for this would be :
P( 1 or 2) = P(1)+P(2)
= 0.05+0.15
= 0.20
Hence, the required probability= 0.20
Answer:
We get value of y: y = 2
Step-by-step explanation:
The points (3,5) and (2, y) are on a line with a slope of 3. Find y.
We can find y using formula of finding slope of a line.
The formula is:
We have and Slope = 3
Putting values and finding y
So, we get value of y: y = 2
Step-by-step explanation:
The line will have the same slope as the given line, which is m = 3. Therefore, the equation of the line in its slope-intercept form is
Next we need to solve for b by plugging in the coordinates of the given point:
So the equation of the line is
Answer:
22, 19, 16
Step-by-step explanation:
To find the first 3 terms substitute n = 1, 2, 3 into the n th term rule
25 - 3(1) = 25 - 3 = 22 ← first term
25 - 3(2) = 25 - 6 = 19 ← second term
25 - 3(3) = 25 - 9 = 16 ← third term
