Answer:
a. 0.333
b. 0.657
c. 1.667
d. -4.07
Step-by-step explanation:
a. Expected time of the first purchase is 10/30 = 0.333
b. Probability for time of 0.14 minutes before first purchase is :
e^-rt, r = 30/10 = 3 , t = 0.14
e^ -3 * 0.14 = 0.65704
c. Expected time until 5th order :
1 / [30/10] * 5 = 1.6667
d. Probability that 8th purchase will occur between 1.33 and 2 minutes ;
[30/10 ] / [ 1/2] = 6
Chi squared distribution ;
1.33 * 6 - 2 * 6 = -4.02
Hi!
So to find out the slope, we can use the equation change in y value over change in x value -- or vertical change over horizontal change.
Find two points on the graph that line up exactly on the lines of the graph, like (20, 0) and (12, 0).
Then, take the change in y value (20-0 = 20) and divide it by the change in x value (0 - 12) to get -20/12, or -5/3.
Hope this helped!!
Answer:
if you take into consideration the run from yesterday,
Joe needs to run at least three more days
y > = 3
if you don't take into consideration the 3 mile run from yesterday,
The answer is
He needs to run 4 or more days to achieve his goal
y > = 4
Step-by-step explanation:
12 miles as a minimum
that means
let x be the total amount of miles ran
x > = 12
Let y be the number of days in which Joe runs
3*y > = 12
y > = 4
Answer:
MN=5.5
Step-by-step explanation:
Thales theorem : MJ/LK = MN/ML = JN/JK
So: MN= (JN*ML)/JK
