Answer:
common ratio
Step-by-step explanation:
When you have a geometric sequence
an = a1 r^(n-1)
The term r is call the common ratio, which is the number we are multiplying by each time
Answer:
0.2103 = 21.03% probability that, in any seven-day week, the computer will crash less than 3 times.
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given interval.
Mean of 0.6 times a day
7 day week, so 
What is the probability that, in any seven-day week, the computer will crash less than 3 times? Round your answer to four decimal places.

In which




So

0.2103 = 21.03% probability that, in any seven-day week, the computer will crash less than 3 times.

Given:
At the store a cell phone cost 1.1 times as much as it sells online.
The cost of it is $888.98 online.
To find:
How much more does it cost from the store?
Solution:
It is given that,
Cost of a cell phone online = $888.98
At the store a cell phone cost 1.1 times as much as it sells online. So, cost of the cell phone at store is

The cost of cell phone at store is $977.878
.
The difference between the cost of cell phone at store and online is

Therefore, the cell phone cost is $88.898 much more at the store.
Answer:
Option (D)
Step-by-step explanation:
Standard equation of a quadratic function is,
ax² + bx + c
Comparing this function with the given quadratic function,
f(x) = 2x² - 4x - 3
a = 2, b = -4 and c = -3
By using quadratic formula to get the value of x,
x = 
= 
= 
= 
= 
Therefore, Susie made a mistake in step IV.
Option (D) is the answer.
