Answer:
There are 21 blue marbles
Step-by-step explanation:
In this question, we are asked to calculate the number of blue marbles in a bag that contains a total of 60 marbles, given the probability of choosing a blue marble.
Mathematically, the probability of choosing a blue marble can be represented as:
P(B) = number of blue marbles/ Total number of marbles
From the question, we can identify that P(B) is 0.35, number of Marbles is unknown while the total number of marbles is 60.
We insert these values in the equation;
0.35 = number of blue marbles/60
Hence, number of blue marbles = 60 * 0.35 = 21
The tree is 19.55 meters tall.
Step-by-step explanation:
Shadow of tree = 20.7 meters
Height of tree = x
Hiker's shadow = 1.8 meters
Hiker's height = 1.7 meters
Using proportion
Shadow of tree : Height of tree :: Shadow of hiker : Height of hiker
Product of mean = Product of extreme
Dividing both sides by 1.8
The tree is 19.55 meters tall.
