Answer:

To solve this problem, we just have to multiply.

(A) The event: woman in the blue class room is related to 60% of women representation and 30% of students representation in the blue classroom.

Therefore, the chances of choosing a woman student from the blue classroom is

[tex]P= 0.60 \times 0.30 = 0.18[/tex]

Which is equivalent to 18% of probability.

We apply the same process to find the probability of choosing a man from the black classroom.

[tex]P= 0.40 \times 0.20 = 0.08[/tex]

Which is equivalent to 8% of probability.

Answer:

24

Step-by-step explanation:

How do we know that a circle must complete up to 180, then we have to:

180 - 48 = 132

Now knowing this distance we can also know the other, starting from the same concept, in addition to what the circle below is like, a semicircle refers to so we divide by 2:

(180-132) / 2 = 24

Therefore the answer is 24.

We can also do it ABC is half of ADC. So ABC = 48/2 = 24

24 is the answer

Answer:

x always comes first so that is 0

then it is y and that is -6 so the answer is (0,-6) aka B

IF i could get brainliest  that would be great

Answer: (0, -6)

Step-by-step explanation: When finding the coordinates of a given point, be very careful with your signs.

On the x-axis, left means negative and right means positive and

on the y-axis, down means negative and up means positive.

So to find the coordinates for point C, we start at the origin

which is where the x-axis and y-axis intercept.

So, we go 0 units to the left or right and 6 units down.

So that's (0, -6).

Remember that the first number in the ordered pair represents the x-coordinate or how far we move to the left or right from the origin and the second number represents the y-coordinate or how far we move up or down from the origin.

Answer:

Step-by-step explanation:

You are given that ...

  40x +40y = 3040

  80x +40y = 3760

Eliminate y by subtracting the first equation from the second:

  (80x +40y) -(40x +40y) = (3760) -(3040)

  40x = 720

  x = 18

Using the first equation to find y, we have ...

  40y = 3040 -40x

  y = 76 -x . . . . . divide by 40

  y = 76 -18 = 58

The cost of a bracelet is $18; the cost of a necklace is $58.

Answer:

2(b + 3c)²(b + 3c)² is equivalent to

2b^4 + 8b³c + 12b²c² + 8b²c³ + 2c^4

Step-by-step explanation:

The expression

2(b + 3c)²(b + 3c)²

Is equivalent to the expression

2(b + 3c)^4

This can be further expanded using the Pascals triangle as

2(b^4 + 4b³c + 6b²c² + 4b²c³ + c^4)

= 2b^4 + 8b³c + 12b²c² + 8b²c³ + 2c^4

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

If you use a table, B is the only point that falls on the graph.

Step-by-step explanation:

When the problem says 3f(x), it means that you are multiplying f(x) by 3. The same goes for 2g(x).

[tex]3(2x^2+8x-4)= 6x^2+24x-12[/tex]

[tex]2(5x+6) = 10x+12[/tex]

Now, we subtract f(x) from g(x) after being multiplied.

[tex](6x^2+24x-12)-(10x+12)[/tex]

[tex]6x^2+14x-24[/tex]

Answer:

34.63

Step-by-step explanation:

A=a2+2aa2

4+h2=32+2·3·32

4+42≈34.63201

Cost of necklace is $939 and cost of bracelet is 645

Given that;

Number of necklace = 1

Number of bracelets = 4

Cost of necklace = Cost of bracelets + 294

Find:

Cost of necklace

Computation:

Assume;

Cost of bracelets = a

Cost of necklace = a + 294

So,

4a + a + 294 = 3519

5a + 294 = 3519

5a = 3225

a = 645

Cost of necklace = 645 + 294

Cost of necklace = $939

Answer:

Step-by-step explanation:

Let the number of days be x because x is the independent variable

Any y is the number of calories consumed the dependent variable.

Now slope = y2 - y2/ x2 - x2

= 10600-4100/8-3

= 6500/5 = 1300

From our analysis we know it consumes 1300 per day so ideally on day 3 we expect him to consume 1300x3= 3900

But the given value is 4100

This means it's inherent energy is 4100-3900= 200

This is the y- intercept and it occurs when x= 0

from the above explanation we know that

C = 200. and it's the y- intercept.

Look at the general equation of a line

y = mx + C; when x= 0, y = C; note we define C as the value of y when x = 0

Answer:

The value of x is 12 feet

Step-by-step explanation:

The shape in question is a composite shape. We can see that x is both the base of the triangle and the breadth of the rectangle.

To get the area of the shape, we will have to add the area of the rectangle to the area of the triangle.

Area of rectangle = length X breadth

Area of triangle = 1/2 base X height.

However, to calculate the area of the triangle, we need to find its height first.

The next step is to get the height of the triangle. Observing the shape properly, we can see that we can get the height by subtracting the length of the rectangle from the overall length of the shape.

Height of triangle = 16 ft - 10 ft = 6 ft

recall area = 156 square feet.

We now have most of our missing dimensions

We can now set up an equation as follows:

[tex](10 \times x) +0.5 \times x \times 6 = 156[/tex]

[tex]10x +3x=156\\13x=156\\x=12 feet[/tex]

Therefore the value of x is 12 feet

Answer:

(x + 1 s 1) n (x + 12 1)

(x +1<1) n (x + 1 > 1)

Step-by-step explanation:

Just simplify each the statements.

Then compare and and see if the statements are contradictory and therefore FALSE, if so, then there is no solution.

(x + 1<-1) n (x + 1< 1)

(x <-2) n (x < 0) which is true, so there is a solution.

(x + 1 s 1) n (x + 12 1)

this doesn't make sense so there is no solution.

(x +1<1) n (x + 1 > 1)

(x < 0) n (x > 0)

This is not possible, the statements are contradictory and therefore FALSE, so there is no solution.

Answer:

Step-by-step explanation:

To find the five-number summary for the commute times (in minutes) of the two samples, we would determine the lowest, highest, first quartile, median and third quartile for each set of values.

1) Considering the data for faculty, arranging in ascending order, it becomes

5 12 12 12 15 22 25 30 35 45

Minimum = 5

Maximum = 45

Median = (15 + 22)/2 = 18.5

Placing the median in the data, it becomes

5 12 12 12 15 18.5 22 25 30 35 45

The median divides the data into the lower and upper halves

First quartile is the 25% mark. It is also the middle of the lower halve. Therefore,

First quartile = 12

Third quartile is the 75% mark. It is also the middle of the upper halve. Therefore,

Third quartile = 30

2) Considering the data for students, arranging in ascending order, it becomes

10 12 14 15 15 20 22 24 25 30

Minimum = 10

Maximum = 30

Median = (15 + 20)/2 = 17.5

Placing the median in the data, it becomes

10 12 14 15 15 17.5 20 22 24 25 30

The median divides the data into the lower and upper halves

First quartile is the 25% mark. It is also the middle of the lower halve. Therefore,

First quartile = 14

Third quartile is the 75% mark. It is also the middle of the upper halve. Therefore,

Third quartile = 24
