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!

First is 42 and the second is 4.5
3 Because 7 x 3 = 21 and 7 + 3 = 10
7 x w = 21 and 7 + w = 10
Answer:
c: 5 x 3/5
Step-by-step explanation:
so the is 15 blocks shaded on the 25 grid
so i would work out each fraction answer and find which one makes 15/25
5 x 5/3 = 25/25
3/5 + 3/5 + 3/5 + 3/5 + 3/5 + 3/5 = 21/5
5 x 3/5 = 15/25
hope this helps :)
if the answer is wrong plz comment and i will fix thanks :)
Step-by-step explanation:
A equation of a line can be represented by
Where m is the slope and b is the y intercept.
For Line A, the slope is 0 so our m is 0 and our y intercept is 4 so our equation will be
For the second equation, qe have no y intercept and a undefined slope so that means that our equation will be in the form of
where a is the x intercept
7 is the x intercept so our equation is
