Step-by-step explanation:

You can solve this by factoring.

The numbers have to add to 10 and multiply to 21.

The first numbers that should come to mind are 7 and 3

The cost of parking in a garage, in dollars, can be modeled by a step function whose graph is shown. How much does it cost to pa

S_A_V [24]

Answer:

the cost is $\$6$

Step-by-step explanation:

observing the graph

we know that

For the interval of x------> $(0,1]$ -----> the cost is $\$0$

For the interval of x------> $(1,3]$ -----> the cost is $\$4$

For the interval of x------> $(3,4]$ -----> the cost is $\$6$

For the interval of x------> $(4,infinite)$ -----> the cost is $\$10$

In this problem we have

$3$ hours and $45$ minutes

therefore

the value of x belong to the interval $(3,4]$

the cost is $\$6$

Suppose that grade point averages of undergraduate students at one university have a bell-shaped distribution with a mean of 2.5

Doss [256]

Answer:

Using the Empirical Rule, we find that .997 (99.7%) of students have grade point averages that are between 1.23 and 3.81.

Step-by-step explanation:

Calculate the z-scores corresponding to a GPA of 1.23 and 3.81.

$\displaystyle z=\frac{1.23-2.52}{.43} = \frac{-1.29}{.43}= -3$
$\displaystyle z=\frac{3.81-2.52}{.43}= \frac{1.29}{.43} =3$

We want to find the area between the z-scores of -3 and 3.

The <u>Empirical Rule</u> tells us that 99.7% of the data lies <em>within three standard deviations</em> under the normal curve.

Therefore, the <u>area</u> between <em>-3 < z < 3</em> is about <u>.997</u>, or around <u>99.7%</u>.
