Answer:
15
Step-by-step explanation:
Let the probability of picking an orange = P(O), and the probability of picking a strawberry = P(S),
Based on the question, he picked an orange first and the probability of picking that is
P(O) = 12/50
Then he picked a strawberry on the second pick, the probability of picking the strawberry is P(S) and we'll find that later.
The probability of picking orange then strawberry with replacement is
P(O) × P(S) = 9/125
Substitute the P(O)=12/50,
12/50 × P(S) = 9/125
P(S) = 3/10
Then by finding the number of strawberry candies, we'll just have to multiply P(S) with the total number of candies, i.e.
Number of strawberry candy
= 3/10 × 50
= 15
Divide the number of revolutions by the number of seconds.
(6 2/5) / (2 2/3) =
Rewrite each mixed numeral as a fraction.
= (32/5) / (8/3)
= 32/5 * 3/8
= 96/40
= 12/5
= 2 2/5
Answer: 2 2/5 revolutions per second
Given:
Shape of the shelf is a right triangle.
Width of the shelf = 9 inches
Length of the shelf = 40 inches
He believes the diagonal will be 41 inches.
To find:
Whether he is accurate or not.
Solution:
According to the Pythagoras theorem,
Using Pythagoras theorem, find the length of the diagonal.
Taking square root on both sides.
But side cannot be negative.
Therefore, the length of the diagonal is 41 inches. So, John is accurate.
