When Samuel commutes to work, the amount of time it takes him to arrive is normally distributed with a mean of 32 minutes and a
k0ka [10]

Answer:

z=\frac{x-\mu}{\sigma}

And we can find the nnumber of deviations from the mean for each limit given:

z_1 = \frac{17-32}{5} = -3

z_2= \frac{47-32}{5} = 3

So we are 3 deviation from the mean and using the empirical rule we know that within 3 deviations from the mean we have 99.7% of the values

Step-by-step explanation:

Let X the random variable that represent the amount of time it takes him to arrive, and for this case we know the distribution for X is given by:

X \sim N(32,5)  

Where \mu=32 and \sigma=5

We want to find this probability:

P(17

And we can use the z score formula given by:

z=\frac{x-\mu}{\sigma}

And we can find the nnumber of deviations from the mean for each limit given:

z_1 = \frac{17-32}{5} = -3

z_2= \frac{47-32}{5} = 3

So we are 3 deviation from the mean and using the empirical rule we know that within 3 deviations from the mean we have 99.7% of the values

Simplify the expression -9-10
denis23 [38]

Answer:

-19

Step-by-step explanation:

When you subtract from a negative it becomes a bigger number in the negatives. Subtract from a negative is also kind of like adding the 2 numbers then making it negative.

<u>Example:</u>

-2 - 2 = -4

2+2=4 making it negative will give you the answer of -4

-9-10 is like 9+10 which equals 19. Making it negative will give you the answer of -19
