Consider a political discussion group consisting of 4 Democrats, 9 republicans, and 4 independents. Suppose that two group membe

rs are randomly selected in succession to attend a political convention. Find the probability of selecting two Democrats.

All in all, we are selecting from a pool of 17 members (4+9+4 = 17). So seeing we have 4 democrats, the probability would be 4/17.

Normally we would simplify the fraction from there but 4/17 is already the simplified form. Therefore that is already the answer.

If 1/2 is 50%, how is 50% converted into a fraction
Dominik [7]

Step-by-step explanation:

Given Input Value = 50%

Place the Percentage Value at the top over 100.

50/100

The given fraction is

50/100

On <u>reducing</u> the fraction, we get the exact form

50/100

which would equal 1/2.

The exact form of the fraction is

1/2

In the decimal form, the fraction can be written as 0.5.

A map of a rectangular park has a length of 4 inches and a width of 6 inches. It uses a scale of 1 inch for every 30 Miles. What
andre [41]

Answer:

Step-by-step explanation:

Dimensions of the rectangular park = 4 inches by 6 inches

Since scale factor = \frac{\text{Dimensions of the park on map}}{\text{Dimensions of the original park}} = \frac{1}{30}

\frac{4}{\text{Length of the original park}}=\frac{1}{30}

Length of the original park = 120 miles

Similarly, width of the park = 180 miles

Area of the park = Length × Width

                           = 120 × 180

                           = 21600 square miles

Therefore, area of the original park is 21600 square miles.

Formula for the ratio of area of the park on map and original park is,

\frac{\text{Area of the park on map}}{\text{Area of the original park}}=(\text{Scale factor})^2

\frac{6}{21600}=(\text{Scale factor})^2

Scale factor = \sqrt{\frac{1}{3600}}

                    = \frac{1}{60}

Scale factor to reproduce the map so that it fits in the brochure will be 1 inch for every 60 miles.

A line is drawn on a coordinate grid by the equation x = 6. Which of the following lines would represent a row parallel to it?
elena-14-01-66 [18.8K]

Answer:

D, x = 3

Step-by-step explanation:

to know if a line is parallel, we need to know what kind of line x = 6 is

we can use the mnemonic VUX/HOY to determine the slope, the type of line, and which axis it corresponds to. VUX/HOY stands for:

Vertical line

Undefined slope

X axis

Horizontal line

0 is the slope

Y axis

according to this, the equation x = 6 is a vertical line

now we can start eliminating answer choices

A. a line containing the point (6,2)

the point lies on the line x = 6, as the x-coordinate in the ordered pair is 6. this  is not parallel to the line

B. y = 6

this intersects x = 6 and is not parallel

C. y = 4

this intersects x = 6 as well and is not parallel

D. x = 3

this leaves us with x = 3, which is a vertical line as seen by the equation and therefore x = 3 is our answer
