Answer:
A Response Variable (or dependent variable) is that variable whose variation depends on other variables In short, the response variable is the subject of change within an experiment, often as a result of differences in the explanatory variables.
Step-by-step explanation:
Answer:
And using the normal standard table or excel we find the probability:

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 avergae number of weeks an individual is unemployed 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, the distribution for the sample mean
is given by:
We select a sample of n =50 people. And we want to find the following probability
And using the normal standard table or excel we find the probability:

Answer:
She mailed 3 to Europe
Step-by-step explanation:
0.94 x 3=2.82
0.44 x 2=0.88
2.82 + 0.88=3.70
Answer:
35
Step-by-step explanation:
23 + 12 = 35
= (20 + 10) + (3 + 2)
= 35
The area of a rhombus is the product of the diagonals divided by 2. In this question, the diagonals are given, so that's really easy. Let's convert the measures to meters, that'll help for the final area calculation:
Area of one rhombus: (0.52x0.30)/2 = 0.078 m²
In 60 m², you can fit 60/0.078 tiles. That's 769.23, rounded to 770 since you'll have to cut up the last tile.
