Answer:
The circumference of Mario's circle is 75 cm
Step-by-step explanation:
<u><em>The correct question is</em></u>
Joe drew a circle whose circumference is 25 cm. Mario drew a circle whose diameter is 3 times the diameter or Joe’s circle. What is the circumference of Mario’s circle?
we know that
All circles are similar
The ratio of the circumferences of two circles, is equal to the scale factor
Let
z ----> the scale factor
x ----> circumference of Mario's circle
y-----> circumference of Joe's circle
so
we have
substitute the given values
solve for x
therefore
The circumference of Mario's circle is 75 cm

Answer:
Option C
Step-by-step explanation:
We want to know the percentage of women among people who only prefer exercise.
We have the following information:
Diet Only Exercise Only Diet and Exercise
Men 7 28 15
Women 22 18 10
Then we get the total of people who prefer just exercise.
Now the proportion of women who only prefer exercise is calculated as:
Therefore we must search among the options the table that shows a proportion of 39 for women who prefer only the exercise.
This table is in option C.
C.
Diet Only Exercise Only Diet and Exercise
Men 0.24 0.61 0.60
Women 0.76 0.39 0.40
Answer:
From $1600 to $3400.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 2500
Standard deviation = 300
What interval of dealer incentives would we expect approximately 99.7% of vehicles to fall within?
By the Empirical Rule, 99.7% fall within 3 standard deviations frow the mean. So
From 2500 - 3*300 = 1600 to 2500 + 3*300 = 3400.
