Answer:
A = π · (r²)
Step-by-step explanation:
π · r² is the area of a circle.
While π · r² · h can also give you the radius, it can only do so for the Volume 
, not the Area 
.
doesn't really apply for a circular object, as it requires the length and width. For circular objects, both are equal to the diameter of the object, and 2² · r² · h does not equal the Volume.
π · r³ seems awfully like the volume of a sphere, but there's something missing. The true volume of a sphere is 
· π · r³, not π · r³.
only applies for triangles.
Given:
A submarine dives below the surface, heading downward in 5 moves.
Each move downward = 200 feet
To find:
The location of submarine after it is finished diving.
Solution:
According to the question,
1 move downward = 200 feet
5 move downward = 5 × 200 feet
= 1000 feet
Since, the submarine heading downward in 5 moves, therefore the submarine is 1000 feet downward after it is finished diving.
Answer: The standard deviation is 0.0998. The 10% condition is met because it is very likely there are more than 250 fish in the river.
Step-by-step explanation:
The standard deviation of the sampling distribution = 
, where p= population proportion and n = sample size.
Let p be the proportion of fish in a river are catfish.
As per given , we have
p= 0.47
n= 25
The, the standard deviation of the sampling distribution will be 
The 10% condition : Sample sizes should be no more than 10% of the population.
But a river can have more than 250 fish [where 10% of 250 =25 (sample size)]
i.e. The 10% condition is met because it is very likely there are more than 250 fish in the river.
So the correct answer is "The standard deviation is 0.0998. The 10% condition is met because it is very likely there are more than 250 fish in the river."
Answer:
So, total gallons were made in all =9.31 gallons
Step-by-step explanation:
We are given
A scientist repeated an experiment three times, making 1.42, 3.81, and 4.08 gallons of a new product
so,
first experiment =1.42 gallons
Second experiment =3.81 gallons
Third experiment =4.08 gallons
now, we can find total gallons
total gallons = first experiment + second experiment + third experiment
total gallons =1.42 gallons + 3.81 gallons +4.08 gallons
total gallons =9.31 gallons
Here I will help you
Step-by-step explanation:
We have to divide 838,880 in to the 50% Like this
838,880/50%=1676
