A class contains 12 female and 20 male students. Find the probability that when two students are chosen randomly from the class, the first student is male and the second student is female.

Write the probability as a fraction in the simplest form.

Answers

3/5 for girls and 2/5 for guys

Answer:

15 / 62

Step-by-step explanation:

Since there 32 students, of which 20 are male, the probability of selecting a student and them being male first is 20/32.

The probability of selecting another student and they are female is 12/31, because the male student is counted out of the selection because he is already picked.

This makes the probability 20/32 x 12/31 = 15 / 62

Alrighty so your gonna start with finding the area of the rectangular prism so 4cm*3cm*12.5cm= 150 cm squared
(Rectangular prism formula is Length*Width*Height)

Then we’re gonna get the triangular prisms area. The formula for it is the same as the rectangular one but once u did it ur gonna divide it in half since a rectangle is made up of 2 triangles!
4cm*3cm*12.5= 150cm then divide it in half to get 75cm squared.

Now just add your rectangular prisms are and your triangular prisms area 150cm+75cm= 225cm squared!

If you look at the figure, you can see there are two shapes; the rectangular prism (bottom) and triangular prism (top). First we find the volume of the rectangular prism by using the formula length x width x height. Put the values in which would be 12.5 x 3 x 4. You get 150cm^3. then for the triangular prism, the formula is V= base x length x height x 1/2. Put the values in, which would be 3 x 12.5 x 4 x 1/2. For that you get 75cm^3. Add both answers together and you get 225 cm^3.

Round to the nearest percent. The average cost of a gallon of gas in January 2014 was $3.42, and was $2.36 in December 2014. What was the percent change in the average cost of a gallon of gas in 2014? Round to the nearest percent.

Answers

It’d be a 31% decrease

The percentage change of the gas will be 45%.

What is the percentage?

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that the average cost of a gallon of gas in January 2014 was $3.42, and was $2.36 in December 2014.

The percentage change will be calculated as,

Percentage change = ( 3.42 - 2.36 ) / 2.36

Percentage change = ( 1.06 / 2.36 )

Percentage change = 0.45 x 100

Percentage change = 45%

50%=0.5

1200*0.5 = 600

The answer is C
The reason to this is because the area of 30 and 40 is 120 and you divide that in half because 50% is half do you would get 600 therefore the answer is 600

Answer:

9. 0.016 pounds (Malika - 1.032; Adrian - 1.016)

10. The best inference I can create that is supported by this data set is that Malika put more potato salad per container (1.032) than Adrian did (1.016).

Step-by-step explanation:

Question #9 asks about the difference between mean masses, so what we need to do first is add up each of the value, and then divide them by 5.

Malika:

(1.1 + 1.08 + 1.05 + 0.95 + 0.98)/5

(2.18 + 2 + 0.98)/5

(3.16 + 2)/5

5.16/5

1.032 is the mean mass for Malika's containers.

Adrian:

(1.3 + 1.21 + 0.79 + 0.9 + 0.88)/5

(2.51 + 1.69 + 0.88)/5

(2.51 + 2.57)/5

5.08/5

1.016 is the mean for Adrian's containers.

Then, subtract the two means.

1.032 - 1.016

The difference between the means is 0.016 pounds (#9's answer).

With that information, we can quickly answer #10. For example, I've put:

The best inference I can create that is supported by this data set is that Malika put more potato salad per container (1.032) than Adrian did (1.016). (My answer for #10.)

What is the area of a square?

A square is a four sided quadrilateral with all of the side having equal lengths. The total internal angle of a square is 360° with each side perpendicular to each other.

A square is a 4 sided polygon where all the sides are of equal length.

The area of the square is the square of any one of its side

Let a be the side of the square

Area of the square = a²

Given data ,

Let the area of the square be represented as A

Now , the value of A is

a = 6 sides

Length of one side = 2 cm

So , total length of one side = 2 x 6 = 12 cm

Now , area of square = ( 12 )² = 144 cm²

And , the area of shaded portion A = area of square - area of triangle

Area of triangle = ( 1/2 ) ( 12 ) ( 12 )

Area of triangle = 72 cm²

Now , A = 144 - 72

A = 72 cm²

Hence , the area is A = 72 cm²
