The answer of this question is C
It shouldn’t the whole number is 2/33 you don’t multiples anything
Given that the ship was traveling for 4 mph faster heading west than south then let the speed of the ship heading south be x mph, the speed of the ship heading west will be (x+4) mph
the distance is given by:
distance=speed*time
distance heading south was:
x*4=4x miles
distance heading west was:
5(x+4)=5x+20
thus the total distance will be given by:
4x+(5x+20)=191
9x+20=191
9x=191-20
9x=171
x=171/9
x=19 mph
the speed the ship used to travel west was:
x+4
=19+4
=21 mph
Answer:
True
Step-by-step explanation:
Assume the following
Mean is represented by μ
Standard deviation by σ
Sample mean by x
Sample Size by n
Given that all possible values of a random variable calculated from a sample of size n with a population mean and standard deviation μ and σ, respectively, it's known that the sampling distribution of the sample mean x is its probability distribution.
Having said that, assume that a simple random sample of size n is drawn from a large population with mean μ and standard deviation σ, as stated above.
The sampling distribution of x will be distributed normally as long as the random variable is normally distributed.
Answer:
5/6+1/8 = 23/24
Step-by-step explanation:
The lowest common denominator here is the smallest denominator that can be divided evenly by both 6 and 8. It is 24. Note that 6 = 2·3 and that 8 = 2·2². We use the factors 2³ and 3 to come up with the LCD 24.
Then 5/6 + 1/8 can be rewritten with this LCD as:
20/24 + 3/24 = 23/24
5/6+1/8 = 23/24
