Answer:
P ($1 or $5) = 5/6
Step-by-step explanation:
There are 6 $1
There are 4 $5
There are 2 $10
There are a total of 12 spaces
P ($1 or $5) = ($1 or $5)/ total
There are 6 ones and 4 fives
= (6+4)/ 12
= 10/12
Divide the top and bottom by 2
=5/6
The x-int is (16,0)
you plug in 0 for y and solve
x-6(0)=16
x=16
the y-int is (0, -8/3)
you plug in 0 for x and solve
0-6y=16
y= -16/6
simplify by dividing both the numerator and the denominator by 2
y= -8/3
The other sides are known as the legs of the triangle.
Answer:
Step-by-step explanation:
Let X be the length of time between billing dates and checks received and deposited for non-delinquent accounts of an oil company’s monthly credit card customers
X has mean 13.5 and sigma 3 days
Sample size = n =36, x bar = 13
(One tailed test at 0.025 sign. level)
Mean diff = -0.5
Since sigma is known z test can be used
Std error =
Z statistic = -0.5/SE= -0.1
p value = 0.920
p>0.025 hence accept null hypothesis.
My conclusion is there is no statistical evidence that lock box reduced the mean time.
