Answer:
A. 0.47 ; B. 0.40 ; C. 0.73 ; D. 0.23 & 4.26
Step-by-step explanation:
- Total Animals = Total Possible Outcomes = 8 + 12 + 6 + 5 + 11 = 42
- Probability = No. of Possible Outcomes / No.of total outcomes
- Odds in favour of event = Prob (Event) / Prob (No Event) ; Odds in against event = Prob (No Event) / Prob (Event)
A. Probability of choosing a Cat = All no. of cats / Total no. of animals
= ( 8 + 12 ) / 42 = 20 / 42 = 0.47
B. Probability of choosing a Common Cat or a Labrador Retriever :-
No. of common cats + no.of labrador retrievers / Total Animals
= (12 + 5) / 42 = 17 / 42 = 0.40
C. Probability of selecting non 'mixed breed' dog :-
No. of animals except mix breed dogs / Total Animals
= ( 8 + 12 + 6 + 5 ) / 42 = 31 / 42 = 0.73
D. Probability of choosing Siamese cat = Siamese Cat / Total Animals = 8 / 42 = 0.19 ; Probability Not choosing Siamese Cat = 1 - Prob (Siamese Cat) = 1- 0.19 = 0.81.
Odds in favour of choosing Siamese Cat :-
Prob (Siamese cat) / Prob (Not Siamese Cat) = 0.19 / 0.81 = 0.23
Odds against choosing Siamese Cat :-
Prob (Not Siamese Cat) / Siamese Cat = 0.81 / 0.19 = 4.26
Answer:
The third one is a rational number
Step-by-step explanation:
This is because the square root of 36 is 6 and the square root of 225 is 15. So the simplified problem for 3 is 6/15 or 2/5
Step-by-step explanation:
Hey there!
Given;
-5/6m = -60
~ Multiply "6m" and "-60".
-5 = 6m*-60
-5 = -360m
~ Divide "-5" by "-360"
m = -5/-360
m = 1/72
Therefore, the value of "m" is 1/72.

To solve this problem, we must remember our conversions: 7 days = 1 week, 1 mile = 5280 feet. If Bob walked 6000 feet in one day, to find the number of feet he walked in a week, we must multiply this value by 7 (because there are 7 days in a week).
6000 * 7 = 42,000
Then, we must divide this amount by 5,280 to find out how many miles Bob walked in the week (because there are 5, 280 feet in one mile).
42,000/5,280 = 7.954545454
However, the question asks us to round to the nearest hundredth of a mile, which means two decimal places.
7.95454 rounds to 7.95 when rounded to the hundredths place, because 4 is less than 5 so we round down.
Therefore, Bob walks 7.95 in one week.
Hope this helps!
