<em>C) 52 m²</em>
- Step-by-step explanation:
<em>A = 2(lw + lh + wh)</em>
<em>l = 4m</em>
<em>w = 3m</em>
<em>h = 2m</em>
<em>A = 2(4m×3m + 4m×2m + 3m×2m)</em>
<em>= 2(12m² + 8m² + 6m²)</em>
<em>= 2×26m²</em>
<em>= 52m²</em>
Answer:
£6
Step-by-step explanation:
Let
Plain scones = x
Cheese scones = 3x
Fruits scones = 4(3x)
= 12x
Total price of scones = £96
She sells each scone for the same price.
Total price of scones = Plain scones + Cheese scones + Fruits scones
96 = x + 3x + 12x
96 = 16x
Divide both sides by 16
x = 96/16
= 6
Plain scones = x = £6
Cheese scones = 3x
= 3(6)
= £18
Fruits scones = 4(3x)
= 12x
= 12(6)
= £72
How much does she make from the sale of the plain scones?
She made £6 from the plain scones
Answer:
3) 0.30
The probability a randomly selected<em> student plays a sport</em> given they work part time = 0.30
Step-by-step explanation:
<u><em>Step(i)</em></u>:-
Given 'A' plays a sport
B work part time
Given P(A) = 0.48
P(B) = 0.40
P(A∩B) =0.12
P(A∪B)¹ =0.24
<u><em>Step(ii)</em></u>:-
By using conditional probability
and similarly
The probability a randomly selected<em> student plays a sport</em> given they work part time
Now
<u>Final answer</u>:-
The probability a randomly selected<em> student plays a sport</em> given they work part time = 0.30
