B. 4/663
C 2/13
D 1/169
Answer:
Step-by-step explanation:
Given the pair of numbers - |-11| and - (-11), we want to determine which is greater or whether they are equal
First lets rewrite both numbers.
- |-11| = -11 (note that the modulus sign will change any negative value into a positive value and that's why |-11| is equivalent to 11)
- (-11) = 11 (note that the negative sign here was retained since it is not an absolute value like the former)
It can be seen that both numbers are therefore not equal i.e - |-11| is less than - (-11). Hence the expression - |-11| < - (-11) is a true statement
2.Is annual income a qualitative or quantitative variable?
3.Is ownership of an American Express card a qualitative or quantitative variable?
4.Does this study involve cross-sectional or time series data?
5. Determine whether the following two statistical inferences may be made based on the sample data collected.
An estimated 59% of the population of subscribers has an annual income of $75,000 or more.
An estimated 60% of the population of subscribers has an American Express credit card.
Answer:
Bloomberg Business week NorthAmerica Subscribers
; Quantitative ; Qualitative ; No ; Yes ; No
Step-by-step explanation:
Sample size = 2861
Percentage respondent with annual income ≥ 75000 = 59%
Percentage having an American Express credit card
1.What is the population of interest in this study?
Bloomberg business week NorthAmerica Subscribers
2. Quantitative
Annual income is quantitative because it is numeric, that is repress red by numbers which can be used to perform sensible numerical computation such as additions, mean, multiplication and so on.
3.Qualitative
No ; ownership of an American express card is a Qualitative variable as it will take responses as (yes or no), even when represented or coded as numbers, it will make no numerical sense to peform mathematical calculations with it.
4.
No ; time series data has to do with data collected with respect to a particular month, year or seasonal data.
5. Determine whether the following two statistical inferences may be made based on the sample data collected.
An estimated 59% of the population of subscribers has an annual income of $75,000 or more.
Yes ;
An estimated 60% of the population of subscribers has an American Express credit card.
No ; the research says 50% and not 60%
G. V = 36h cubic units
H. V = 18h cubic units
J. V = 12h cubic units
Answer:
J. V = 12h cubic units
Step-by-step explanation:
Volume if a square pyramid = ⅓*a²*h
Where,
h = height = ?
a = edge = 6 in.
Plug in the values
Volume = ⅓*6²*h
V = ⅓*36*h
V = 12*h
V = 12h cubic units
Answer:
0.11
Step-by-step explanation:
The events are independent, so:
P(A and B) = P(A) × P(B)
P = 0.5 × 0.22
P = 0.11
