Jane works as a tutor for $14 an hour and as a waitress for $11 an hour. This month, she worked a combined total of 93 hours at

daser333 [38]

Answer:

3t + 1,023

Step-by-step explanation:

The computation is shown below:

As a tutor it is $14 per hour

As a waitress it is $11 per hour

Total number of hours worked is 93

Now let us assume the number of hours worked as a tutor is t

So as a waiter is 93 - t

Now the equation is

= $14(t) + $11(93 - t)

= 14t + 1,023 - 11t

= 3t + 1,023

The mean percent of childhood asthma prevalence in 43 cities is 2.32%. A random sample of 32 of these cities is selected. What

lidiya [134]

Answer:

$P(\bar X>2.8)$

We can use the z score formula given by:

$z=\frac{\bar X -\mu}{\frac{\sigma}{\sqrt{n}}}$

And replacing we got:

$z=\frac{2.8 -2.32}{\frac{1.24}{\sqrt{32}}}=2.190$

And using the normal standard distribution and the complement rule we got:

$P(z>2.190 )= 1-P(z$

Step-by-step explanation:

For this case w eknow the following parameters:

$\mu = 2.32$ represent the mean

$\sigma =1.24$ represent the deviation

n= 32 represent the sample sze selected

We want to find the following probability:

$P(\bar X>2.8)$

We can use the z score formula given by:

$z=\frac{\bar X -\mu}{\frac{\sigma}{\sqrt{n}}}$

And replacing we got:

$z=\frac{2.8 -2.32}{\frac{1.24}{\sqrt{32}}}=2.190$

And using the normal standard distribution and the complement rule we got:

$P(z>2.190 )= 1-P(z$
