Answer:

The manager's estimate was really accurate. The correct income was of 6408 $ instead of the 6400$ he estimated.

Step-by-step explanation:

There are 37 x 23 = 851 seats. 200 of them are occupied by children, 651 are occupied by adults.

200 x 6 = 1200 $ are raised with child tickets,

651 x 8 = 5208 $ are raised with adult tickets.

The total income is 1200 + 5208 = 6408 $, so the manager's estimate was really accurate.

D: Applicant presents a drivers license

M applicant presents a marriage license

1.)

This means that any one of the three must be presented :

Birth certificate OR Driver's license OR Marriage certificate

B v D v M

2.)

This means any two combination of the three certificates :

(birth certificate and marriage certificate) OR (birth certificate and driver's license) OR (marriage certificate and driver's license)

The average home price in Massachusetts is $410,000, with a standard deviation of $65,000. A city planner is studying the distri
77julia77 [94]

Answer:

P(z

And replacing the value obtained we got:

z=-1.282

And if we solve for a we got

a=410000 -1.282*\frac{65000}{\sqrt{200}}=404107.68

Step-by-step explanation:

Let X the random variable that represent the average home prices of a population, and for this case we know the distribution for X is given by:

Where \mu=410000 and \sigma=65000

For this part we want to find a value a, such that we satisfy this condition:

P(X>a)=0.90   (a)

P(X   (b)

We want to find a value who accumulate 0.10 of the area on the left and 0.90 of the area on the right of the normal standard distributon and for this case it's z=-1.282

And using the distribution for the sample mean we can do this:

P(X  

P(z

And replacing the value obtained we got:

z=-1.282

And if we solve for a we got

a=410000 -1.282*\frac{65000}{\sqrt{200}}=404107.68

The answers are D.)3, B.) Values were not subtracted from each side, and A.) The substitution property of equality

<h3>What is a straight line?</h3>

A straight line is a combination of endless points joined on both sides of the point.

We have;

UX=WZ

VW=XY

In line 3 the statement does not justify.

Because values were not subtracted from each side.

The reason should be substitution property of equality.

Thus, the answers are D.)3, B.) Values were not subtracted from each side, and A.) The substitution property of equality
