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.
Answer:
C
Step-by-step explanation:
Dividing zero by any value gives a result of zero, thus
= 0 → C
Answer: $96
Step-by-step explanation:
12x2=24
24x4=96
Hopefully this is good enough but this is what I got
In mathematics<span>, </span>trigonometric identities<span> are equalities that involve </span>trigonometric functions<span> and are true for every value of the occurring </span>variables<span> where both sides of the equality are defined. Geometrically, these are </span>identities<span> involving certain functions of one or more </span>angles<span>.

So we know this identity:
Given that α = 20° and β = 4°, the solution is:
The equation of parabola is . If a is positive and is always greater than zero or equal to zero, then x is also greater or equal to zero. This means that parabola is determined for non-negative x and for all real y.
Tha canonical equation of parabola is , where p>0. The branches of this parabola go up in positive y-direction. When you change x to y and y to x, then the branches of parabola go in positive x-direction, that is right.
Answer: correct choice is A.
