Step-by-step explanation:
Answer:
look at the picture above
Answer:
95% of premiums that are between $600 and $1300.
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 = 950
Standard deviation = 175
Estimate the percent of premiums that are between $600 and $1300.
600 = 950 - 2*175
So 600 is two standard deviations below the mean.
1300 = 950 + 2*175
So 1300 is two standard deviations above the mean
By the Empirical Rule, 95% of premiums that are between $600 and $1300.
Answer:
The x-intercepts are where the graph crosses the x-axis, and the y-intercepts are where the graph crosses the y-axis. An x-intercept is a point on the graph where y is zero, and a y-intercept is a point on the graph where x is zero.
Step-by-step explanation:
Answer:
a) x = 3.0625m
y = 45.9375 m
b) A = 140.68359375 m²
Step-by-step explanation:
Let x be the length
Let y be the width
2x + 2y = 98
x + y = 49
y = 3(5x)
y = 15x
x + 15x = 49
16x = 49
x = 3.0625 m
y = 15(3.0625) = 45.9375
A = xy = 3.0625(45.9375) = 140.68359375
