Answer:
B. 72 cm by 108 cm
Step-by-step explanation:
We know scale is 4 cm:30 ft. So find how many time 30 ft goes into each measurement of playground and then multiply that by 4...
540/30=18
18×4=72
810/30=27
27x4=108
Answer:
Each value (1 to 6) has exactly the same probability of being rolled.
Step-by-step explanation:
Given
Rolls: 10
Outcome: 5 5 1 3 2 1 5 6 5 1
Required
Which is true about the next 10 rolls
In the roll of a fair die (as stated in the question), each face has equal probability of being the outcome of individual rolls.
This implies that options (a), (b) and (c) are not true because they do not support the above statement,
<em>Hence, (d) is correct</em>
The number of student tickets is 175 and the number of adult tickets is 425.
<h3>What is an expression?</h3>
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
<h3 />
Given that:-
- A concert manager counted 600 ticket receipts the day after a concert. The price for a student ticket was $13.50, and the price for an adult ticket was $17.00. The register confirms that $9,587.50 was taken in
Suppose the number of the student ticket is St and adult are At.
St + At = 600
St = 600 - At
Another expression for the total amount will be given as:-
13.5St + 17At = 9587.50
Put the value of St in the equation to find the value of At.
13.5( 600 - At) + 17At = 9587.50
8100 - 13.5At +17At = 9587.5
17At - 13.5 At = 9587. 5 - 8100
3.5 At = 1487.5
At = 425
St + At = 600
St = 600 - At = 600 - 425 = 175
Therefore the number of student tickets is 175 and the number of adult tickets is 425.
