Answer: Each catalog weighs 0.87 pounds
Step-by-step explanation:
Given: Number of identical catalogs = 8
Weight of package with the catalogs= 6.96 pounds
Using division operator,
Weight of each catalog = (Weight of package ) ÷ (Number of identical catalogs)
i.e. Weight of each catalog =(6.96)÷8 pounds
⇒ Weight of each catalog = 0.87 pounds
Hence, Each catalog weighs 0.87 pounds
The gradient in the equation would be 1/4x
Answer:
Theoretical probability: 50/100 or 50%
Experimental probability: 12/20 or 60%
Step-by-step explanation:
Let's find out both probabilities asked.
Theoretical probability:
In the whole bank, here are 100 coins (20 nickels + 30 quarters + 50 one-dollars), among which there are 50 one-dollar coins. So the probability to pick up a one-dollar coin is 50 out 100, so...
TP = 50/100 or 50%
Experimental probability:
For the experimental probability, we know Jonathan picked out 20 coins, out of which 12 were one-dollar coins, so the probability is 12 out of 20...
EP = 12 / 20 = 60%
