Answer:
16.7%.
Step-by-step explanation:
There are initially
pencils in the bag.
Take a pencil out of this bag of 47 pencils. 15 out of the 47 pencils blue. Let
represent the event of getting a blue pencil on the first pick. The probability of getting a blue pencil is:
.
There are now
pencils left in the bag. However, given that the first pencil removed from the bag is blue, the number of red pencils in the bag will still be 24. Take another pencil out of this bag of 46 pencils. Let
represent the event of getting a red pencil on the second pick. The possibility that the second pencil is red given that the first pencil is blue will be:
.
The question is asking for the possibility that the first pencil is blue and the second pencil is red. That is:
.
Answer:
x = 37.5
Step-by-step explanation:
By Basic Proportionality Theorem:

Answer: The jet will fly 4400miles in 8 hours.
Step-by-step explanation:
Let the missing value be represented by x
2 hours = 1100 miles
8 hours = x
We cross multiply:
2x = 1100 x 8
2x = 8800
Divide both sides by 2 to get the value of x
x = 8800/2
x = 4400
Therefore, the jet will fly 4400miles in 8 hours.
The height of the cone is 4 cm (approx).
Step-by-step explanation:
Given,
The radius (r) of the cone = 4.96 cm
Volume (V) = 102 cm³
To find the height (h) of the cone.
Formula
The volume of a cone V =
πr²h
Now,
According to the problem,
πr²h = 102
or,
×
×(4.96)²h= 102
or, h = 
or, h = 3.95 = 4 (approx)
so,
Height = 4 cm (approx)
