Answer: D. The probability of a time from 75 seconds to 250 seconds.
Step-by-step explanation:
We know that a density curve graph for all of the possible values from a to b can be used to find the the probability of the values from a to b .
Given: A density graph for all of the possible times from 50 seconds to 300 seconds.
Then it can be used to find the the probability of a time in the range from 50 seconds to 300 seconds.
From all the given option only option D gives the interval which is lies in the above range.
i.e A density graph for all of the possible times from 50 seconds to 300 seconds can be used to determine the probability of a time from 75 seconds to 250 seconds.
Answer:
$20d = c
Step-by-step explanation:
Since the cost is $20 per day, $20d ($20 for how many days) would be the start of the equation.
C = cost, and $20d will determine the cost, so $20d = c
is your final answer/equation.
Cheers!
Answer: x=40 y=140
Step-by-step explanation:
To work out x:
The angles in a triangle always add up to 180.
You already have one angle which is 50 the bottom left angle is a right angle and right angles always equal 90. To work out x, do 50+90=140 then do 180-140=40.
To work out y:
Angles on a straight also add up to 180.
So as you have figured out what x is (40) you would take it away from 180 to give you y.
180-40=140
Hope this helps :)
Answer:
The length of the rectangle=16/45 feet
Step-by-step explanation:
The area of a rectangle is given by;
A=L×W
where;
A=area of the rectangle
L=length of the rectangle
W=width of the rectangle
In our case;
A=(8/10) square feet
L=unknown
W=2 1/4 feet=9/4 feet
replacing;
8/10=l×9/4
l=8/10×4/9
l=16/45 feet
The length of the rectangle=16/45 feet
