A recent survey by the American Automobile Association showed that a family of two adults and two children on vacation in the Un

masha68 [24]

Answer: We are given:

$\mu=247,\sigma=60$

We need to find the z scores for the following vacation expense amounts:

$197, $277, $310

We know that z score formula is:

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

When $x = 197$ , the z score is:

$z=\frac{197-247}{60}$

$=\frac{-50}{60}$

$=-0.83$

When $x = 277$ , the z score is:

$z=\frac{277-247}{60}$

$=\frac{30}{60}$

$=0.5$

When $x = 310$ , the z score is:

$z=\frac{310-247}{60}$

$=\frac{63}{60}$

$=1.05$

Therefore, the z scores for the vacation expense amounts $197 per day, $277 per day, and $310 per day are -0.83, 0.5 and 1.05 respectively

If an object is projected upward with an initial velocity of 129 ft per sec, its height h after t seconds is h = -16^2+123t. Fin

elena-s [515]

This problem can be solved directly by neglecting the initial velocity given. All we have to do is to plug in t = 4 in the given equation. That is:

h = -16^2 + 123 * 4

h = 236 ft

The area of a small pond is 78.5 yds. What is the diameter of the pond?

Zolol [24]

Answer:

Diameter of pound = 10 yd

Step-by-step explanation:

Given area of circular pond = 78.5 square yd

To find the diameter of the pond.

Solution:

The pond being circular in shape, the area of pond can be given as:

⇒ $\pi\ r^2$

where $r$ represents radius of the pond.

Thus, we have:

⇒ $\pi\ r^2=78.5$

Using $\pi=3.14$

⇒ $3.14r^2=78.5$

Solving for $r$

Dividing both sides by 3.14

⇒ $\frac{3.14r^2}{3.14}=\frac{78.5}{3.14}$

⇒ $r^2=25$

Taking square root both sides.

⇒ $\sqrt{r^2}=\sqrt{25}$

⇒ $r=\pm5$

So, radius = 5 yd, as distances are always positive.

Diameter = $2\times radius=2\times 5\ yd= 10\ yd$

Thus, diameter of pound = 10 yd
