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!

The missing length of the triangle is 35 units.
According to the question,
We have the following information:
We have a figure of triangle where a line is drawn parallel to the base of the triangle.
Now, we know that in this case the ratio of the corresponding sides of the triangle will be equal.
Let's take the missing length to be x units.
So, we have the following expression:
x/28 = 15/12
Using the cross multiplication method:
12x = 28*15
x = 28*15/12
Dividing by 12 on both sides of the equation:
x = 35 units
Hence, the missing length of the triangle is 35 units.

$72
Since 20% of 60 is 12 (do .2 * 60) you add $12, which is the answer to the multiplication, to the original.
