Answer:
125 times.
Step-by-step explanation:
Prob(Heads) = 1/2.
Prob(Spinner lands on 2) = 1/4 ( as there are 4 sections on the spinner).
So the best prediction for the number of times this occurs in a 1000 trials
= 1/2 * 1/4 * 1000
= 1/8 * 100
= 125 times.
Answer:
it's the second one

Answer:
28 quarters
Step-by-step explanation:
28 quarters = $7.00
16 dimes = $1.60
(28 + 16 = 44 and $7.00 + .60 = $7.60)
5.8 = 58/10 = 29/5 ;
1.2 = 12/10 = 6/5;
(29/5) ÷ (6/5) = (29/5) × (5/6) = 29/6 = 4.83;
The correct answer os D.
Answer:
C. 1 and 3
Step-by-step explanation:
You are right, now here's why.
You are looking for two equations that have the same constant of proportionality. That means they behave the same, that if you enter a X value in one, you'll get the same effect as if you enter it in another.
If you look at all four equations, you'll see that 1 and 3 are essentially the same thing, just that the first one is simplified (4y = 3x) while the other isn't (8y = 6x). But for each time you enter a X value, the Y value will be 33% (1/3) bigger.
