Answer:
Gareth has a deck of cards with 12 challenge cards and 8 prize cards.
=> The probability he selects a prize card: P = 8/(12 + 8) = 8/20 = 0.4
Gareth is going to randomly select a card from the deck 148 times, replacing the card and shuffling the deck after each selection .
=>The randomness is kept same for all selecting times
Then the best prediction for the number of times Gareth will select a prize card:
=> N = 0.4 x 148 = 59.2 = 59 times
Hope this helps!

Answer:
1
Step-by-step explanation:
Answer:
Our inequality is 8 < x < 10, where x is our number.
Since the problem doesn't specify whether the number x is an integer or not, we can assume that x can be either a decimal or a whole number. That means that we want any decimal number or whole number between 8 and 10. The only whole number is 9, but there are infinitely many decimal solutions. For example, we could have 8.001, 8.0001, 8.00001, etc.
Thus the answer is D.

<u>Answers</u>
C = 58.84
B = 97.16°
<u>Explanation</u>
The sine rule states:
SinA/a = sinB/b
∴ sin24 / 77 = sinC / 162
sinC = (162 × sin24)/77
= 65.89/77
= 0.85573
C = 58.84°
Angles in a triangle add up to 180°
∴ B + 24 + 58.84 = 180
B = 180 - 24 - 58.84
= 180 - 82.84
= 97.16°
