Part 10, What is the area of this figure? NO LINKS!!!​
Tamiku [17]

Answer:

shaded area  = 601 mm²

Step-by-step explanation:

Area of rectangle = Length * Breadth

Area of first section = 12 * 16 = 192 mm²

Area of 2nd middle section = 8 * ( 16 - 10 ) =  48 mm²

Area of the bottom section = 19 * 19 = 361 mm²

Area of total therefore = 192 mm² + 48 mm² + 361 mm²

                                      =  601 mm²

When Harper commutes to work, the amount of time it takes her to arrive is normally distributed with a mean of 24 minutes and a
Korvikt [17]

Answer:

\mu -2\sigma = 24-2*3= 18

\mu -2\sigma = 24+2*3= 30

So then we can conclude that we expect the middle 95% of the values within 18 and 30 minutes for this case

Step-by-step explanation:

For this case we can define the random variable X as the amount of time it takes her to arrive to work and we know that the distribution for X is given by:

X \sim N(\mu = 24, \sigma =3)

And we want to use the empirical rule to estimate the middle 95% of her commute times. And the empirical rule states that we have 68% of the values within one deviation from the mean, 95% of the values within two deviations from the mean and 99.7 % of the values within 3 deviations from the mean. And we can find the limits on this way:

\mu -2\sigma = 24-2*3= 18

\mu -2\sigma = 24+2*3= 30

So then we can conclude that we expect the middle 95% of the values within 18 and 30 minutes for this case
