Answer:
a. 0.68 or 68%
b. 0.08 or 8%
c. 0.32 or 32%
Step-by-step explanation:
Probability of reaching client on the first call = 60%
Probability of reaching client on the second call = 20%
a. The probability that the manager reaches her client in two or fewer calls is the probability of reaching a client with one or two calls:
b. The probability that the manager reaches her client on the second call but not on the first call is:
c. The probability that manager is unsuccessful on two consecutive calls (needing more than two calls), P(X>2), is:
Answer:
The slope - intercept equation for this line is y = 17x - 55
Step-by-step explanation:
The general form of the slope-intercept form is
y = mx +b
where m is the slope and b is the y-intercept.
We are given slope m = 17
we need to find b the y-intercept.
To find y-intercept we would use point(3,-4) and formula
y = -4
x = 3
m = 17
b=?
y = mx + b
-4 = (17)(3) + b
-4 = 51 + b
b = -4 -51
b = -55
So, y-intercept is -55
The slope - intercept equation for this line is y = 17x - 55
Answer:
18
Step-by-step explanation:
x = number
45 + 1/2 x = 3x
45 = 2.5 x
x = 45/2.5 = 18
Answer:
x=3, y=-6
Step-by-step explanation:
As you know there are many ways to solve this question! First is Subsitutuion, Second is Elimination, and Third is Graphing!
Let’s begin with our detailed answer:
As you know subsitution is solving for a variable and then it can be used as a variable substitution to figure out x and y.
So in our system of equations:
I will just take one equation and solve for x but it actually dosent matter which variable you subsitutue and solve for.
To eliminate this question we can divide the top part by -3:
Let‘s sum these system of equation and we get:
We can now insert y as -6 and solve for x:
So,
