When you roll a pair of dice, there are several outcomes, as shown below:When rolling the dice, the outcome is expressed as a sum of the two dice. Forexample, if after you rolled the dice, and one die was a 3 and the other was a 4, youwill have rolled a 7.Select all of the TRUE statements below. There may be more than one.The probability of rolling the same digit with each die is 1/4.The odds in favour of rolling a 10 is 1:13.The odds against rolling a number less than 7 is 7:5.

You select two cards from a standard deck of 52 cards, one after the other. What is the probability that you select and ace then a king? A. 1/13
B. 4/663
C 2/13
D 1/169

Answers

it would be 1/169 because it is not very likley

It would be 2/13 because imagine being given 4 decks of 13 cards and you have. Higher chance of having one to two of an ace or king in the deck compared to pulling none to all four. So 2/13 due to the ratio of 13

Insert <, >, or = between the given pair of numbers to make a true statement.- |-11| - (-11)

Answers

Answer:

- |-11| < - (-11)

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

A Bloomberg BusinessWeek North American subscriber study collected data from a sample of 2861 subscribers. Fifty-nine percent of the respondents indicated an annual income of $75,000 or more, and 50% reported having an American Express credit card.1.What is the population of interest in this study?

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.

Answers

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.

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%

Look at the square pyramid shown below. Which of the equation best represents volume of this pyramid terms of H?F. V = 2h cubic units

G. V = 36h cubic units

H. V = 18h cubic units

J. V = 12h cubic units

Answers

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
