Answer:
347.55
Step-by-step explanation:
331 x 0.05 =16.55
16.55 + 331 = 347.55
Answer:
30/10 and 5/11
Step-by-step explanation:
Answer:
Where
and
Then we have:
With the following parameters:


Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the number of cars running a red light of a population, and for this case we know the distribution for X is given by:
Where
and
Since the distribution for X is normal then we know that the distribution for the sample mean
is given by:
With the following parameters:


Answer:
13.5 yards
Step-by-step explanation:
as They have asked for the width (only).
9 is width and they told 2 INCHES is 3 YARDS So

and the normal

and area is

Perimeter is

Sorry if its wrong
The given sequence is neither arithmetic nor geometric.
Further explanation:
In order to check whether a sequence is geometric or arithmetic we have to find the common ratio and common difference respectively
Common difference is the deifference between cunsecutive terms of a sequence while common ratio is the ratio between two consecutive terms.
Common difference is denoted by d and common ratio is denoted by r
- If the common difference is same then the given sequence is an arithmetic sequence
- If the common ratio is same then the given sequence is a geometric sequence
Given
1, 3, 6, 10, 15
Common difference:
Here

As the common difference is not same, the given sequence is not an arithmetic sequence
Common Ratio:

As the common ratio is also not same the sequence is not a geometric sequence.
The given sequence is neither arithmetic nor geometric.
