Answer:
The value of y is 125 when x=25.
Step-by-step explanation:
It is given that y varies directly as x. It means y is proportional to x.
Where k is constant of proportionality.
It is given that y=25 when x=5. Put x=5 and y=25 in the above equation to find the value of k.
Divide both sides by 5.
The value of k is 5.
The relation between x and y is defined by the equation
Put x=25 in the above equation.
Therefore the value of y is 125 when x=25.
Answer:
m=18
Step-by-step explanation:
2=m/2-7
+7 +7
9=m/2
2 * 9=m/2 * 2
18=m
Answer:
170 is the answer of mine
The probability that out of 8 newly hired people is 3.2.
According to the statement
we have given that the some conditions and based on these conditions we have to find the probability that out of 8 newly hired people.
So, For this purpose,
we have given that the
new employee in a fast-food chain still being with the company at the end of the year is 0.5
Now, we See that is probability of remaining with the company.
There is only one is 0.5.
According to the probability law
P + Q = 1
and this become
Q = 1 - 0.60.
And the probability of one people hired is Q.
Then
Q = 0.4
And probability that out of 8 newly hired people is
8Q = 0.4 * 8
it become 3.2.
So, The probability that out of 8 newly hired people is 3.2.
