Answer:
C. 60,000
Step-by-step explanation:
<u>Given</u>
- 24,000 fans attended a football match
- three times as many bought tickets
- one-sixth of them cancelled their tickets
<u>Three times as many bought tickets</u>
24,000 * 3 = 72,000
<u>one-sixth of them cancelled their tickets</u>
72,000 * 1/6 = 12,000
<u>Subtract</u>
72,000 - 12,000 = 60,000
<u>Answer</u>
60,000 people are attending this week
Natural numbers: Counting things! You look around your room and see an electronic device, then another, then another! You just counted to 3 using the natural numbers.
Whole numbers! You try to look for electronic devices and realise that they’re all gone. You have zero electronic devices, and you just used whole numbers.
You go online to find where your electronic devices went, and realise they were taken because you’re in debt to the bank so they took some of your stuff. You’re in negative numbers, and now you’ve used integers.
Answer:
<h2>p(obtaining a red counter) = 0.625</h2>
Step-by-step explanation:
The total number of counters in the bag is 5 + 3 = 8.
and only 5 are red.
Then
the probability of obtaining a red counter is :
Answer:
(x + 1)^2 + (y - 2)^2 = 3^2 = 9
Step-by-step explanation:
The standard equation of a circle with center at (h, k) and radius r is
(x - h)^2 + (y - k)^2 = r^2.
Here, h = -1, k = 2 and r = 3, so the equation of this particular circle is
(x + 1)^2 + (y - 2)^2 = 3^2 = 9.
Answer:
x ∉ R
Step-by-step explanation:
x² = - 21
if x² < 0 => x ∉ R
