Answer:

The correct one is the bottom choice.

Step-by-step explanation:

This is because the proportion is saying that side BC over side YZ is the same as 28 over 14. This is correct because 28 and 14 are the actual lengths of these sides of the triangle. The other choices do not relate to the same sides of both triangles.

Maria Addai has been offered a future payment of $990 two years from now. If she can earn 8.2 percent compounded annually on her

IgorLugansk [536]

Answer:

845.6306

Step-by-step explanation:

Firstly this is annuity based

Let, investment at beginning of year = <em>x</em>

Then value at year 1 end = x + (8.2% $\times$ x)

Value at end of year 2 = (x + 0.082x) + (8.2% $\times$ (x + 0.082x))

Now this value = $990

Therefore,

990 = (x + 0.082x) + ((x + 0.082x) $\times$ 8.2%)

990 = x + 0.082x + 0.082x + 0.006724x = 1.170724x

x = 990/1.170724 = 845.6306

In a survey of 248 people, 156 are married, 70 are self-employed, and 25 percent of those who are married are self-employed. If

MatroZZZ [7]

Answer:

The probability of selecting a person which is self-employed but not married equals 1/8.

Step-by-step explanation:

Here, the given survey says:

Total number of people surveyed = 248

Number of people married = 156

The number of people are self employed = 70

Now, 25% of people who are married are SELF EMPLOYED.

Now, calculating 25% of 156 , we get:

$\frac{25}{100} \times 156 = 39$

⇒ out of total 156 married people, 39 are self employed.

So, number of self employed people but not married

= Self employed people - Self employed people PLUS married

= 70 - 39 = 31.

So, the probability that the person selected will be self-employed but not married = $\frac{\textrm{The total number of people self-employed but not married}}{\textrm{Total Number of people}}$ = $\frac{31}{248} = \frac{1}{8}$

Hence The probability of selecting a person which is self-employed but not married equals 1/8.
