Step-by-step explanation:

Given that:

Cost function of banner advertisement:

C(n) = 0.30n + 5.00

n = average number of hits per hour

5 = flat rate

From the function, C(n), the cost per hit is the slope value of the function ; which is 0.30

1.) If the cost of pop-up advert will double the cost per hit, the cost function for pop-up advert will be :

D(n) = 2(0.30n) + 5

D(n) = 0.60n + 5.00

B.) This change in cost per hit has resulted in change in slope which is defined as :

[Rise / run = vertical change / horizontal change].

Hence, both vertical and horizontal change has occurred.

Answer:

14 inch ^2

Step-by-step explanation:

Area of a trapezium= (a+b) 2 times h

so side a= 5 inches

    side b= 9 inches

then times by 2 times the height (2)

you can rearrange the formula to this- a + b/ 2 times height.

5+9/2 times 2= 14

I hope this helps, have a lovely day.

Answer:

Step-by-step explanation:

For an increase of one hour in time worked, the predicted increase in the amount of money spent on entertainment is 1.86 units.

To find the predicted increase in the amount of money spent on entertainment for an increase of one hour in time worked, we need to find the slope of the line, which is the coefficient of x in the equation.

which means that for every one unit increase in x (which in this case is one hour worked), y (which in this case is the amount of money spent on entertainment) is predicted to increase by 1.86 units.

This is the change in the dependent variable (y) for a unit increase in the independent variable (x), based on the linear relationship described by the equation of the line fit.

Answer:

Option B. 3 liters

Step-by-step explanation:

First, we shall determine the total volume of soup that Mei have. This is illustrated below:

Mei have 8 jars of soup containing 300mL each. Therefore, she has a total of = 8 x 300mL = 2400mL.

Next, we shall convert 2400mL to litres (L). This can be obtain as follow:

1000mL = 1L

Therefore, 2400mL = 2400/1000 = 2.4L

Mei have 2.4L of soup.

Since the total volume of the soup that Mei have is 2.4L, she will be needing a minimum of 3L pot to heat up all the soup.

=========================================================

Explanation:

Add up the first two frequencies to get 14+18 = 32

The table shows that the person rolled either a "1" or a "2" a total of 32 times, which is the amount of rolls getting less than "3".

This is out of the 200 rolls total.

32/200 = (8*4)/(8*25) = 4/25

In decimal form, this would be 4/25 = 0.16 which is exact.

Answer : 4 times

Here it's given that ,

And we need to find out how many times the area of red winged butterfly is greater than that of sitting on the flower (blue butterfly) .

Let us take ,

Then ,

We know that ,

→ area of the triangle = 1/2 × base × height

So that ,

→ A/A' = (1/2 * b * h) ÷ (1/2 *2b *2h)

→ A/A' = bh/4bh

→ A/A' = 1/4

→ A' = 4A

Henceforth the area of blue butterfly is 4 times greater than that of red winged butterfly .

I hope this helps.

The solution is (3, 4) hence, there is a unique solution so the system is consistent and the equations are independent.

Since we know that system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

We are given the system of equations as;

x + 4y = 19

x - 2y = -5

The second equation tells us that x = 2y -5.  

Substitute this 2y -5 into the first equation, as follows:  

x + 4y = 19

2y -5 + 4y = 19

Combining like terms, we get

6y = 24

y = 4

Subbing this result into the second equation, we find x:  

x + 4y = 19

x = 19 - 16

x = 3

.  

The solution is (3, 4).

Hence, the system is consistent and the equations are independent.

Answer:

A

Step-by-step explanation:

First off we can see that there are 46 pencils - and 7 students - so we can divide the two

46/7 is not a whole number, so we need to find a number that can be multiplied by 7, and is right below 46.

If you multiply 7 by 6, you get 42, which is the highest you can get with multiply by 7, which is also below 46.

Now that we know that each student gets 6 pencils, we need to find out how many are left.

We can do 46 (total pencils) minus 42 (pencils given) to get a leftover of 4 pencils, so the answer is A.

The probability that the second ball you draw is gold is 0.619.

What is the probability?

A probability is a number that reflects the chance or likelihood that a particular event will occur. Probabilities can be expressed as proportions that range from 0 to 1, and they can also be expressed as percentages ranging from 0% to 100%.

Here, we have

Given: a room contains several urns 13 urns contain two gold balls, 6 urns contain one gold ball and one silver ball, 20 urns contain two silver balls.

Conditional probability is a measure of the probability of an event occurring given that another event has occurred.

Here given event is that first ball is gold. Hence sample space will have 13+8 = 21 urns.

For second ball to be gold, urn should have 2 gold balls hence it has 13 urns under above condition.

Probability = 13/21 = 0.619

Hence, the probability that the second ball you draw is gold is 0.619.

Answer:

16,777,216 bacterias.

Step-by-step explanation:

There are 24 hours in one day, and the given bacteria (1) doubles every hour.

Hour 0: 1

Hour 1: 1 x 2 = 2

Hour 2: 2 x 2 = 4

Hour 3: 4 x 2 = 8

Hour 4: 8 x 2  = 16

Hour 5: 16 x 2 = 32

Hour 6: 32 x 2 = 64

Hour 7: 64 x 2 = 128

Hour 8: 128 x 2 = 256

Hour 9: 256 x 2 = 512

Hour 10: 512 x 2 = 1,024

Hour 11: 1,024 x 2 = 2,048

Hour 12: 2,048 x 2 = 4,096

Hour 13: 4,096 x 2 = 8,192

Hour 14: 8,192 x 2 = 16,384

Hour 15: 16,384 x 2 = 32,768

Hour 16: 32,768 x 2 = 65,536

Hour 17: 65,536 x 2 = 131,072

Hour 18: 131,072 x 2 = 262,144

Another way to do it is using exponential functions. If it doubles every hour as such: \(2^{x}\)  , in which x is the amount of hours: \(2^{24} = 16777216\)

Answer:

Step-by-step explanation:

You would first have to plug in for x, (which is already given). After plugging in for x, you would need to solve the equation to get y.

Once you have both x and y, you will have your (x,y)

For example: (given x value = -5)

\(f(x) = -|x - 5| -4\\f(-5) = -|(-5) - 5| - 4\\f(-5) = -|-10| - 4\\f(-5) = -10 - 4\\f(-5) = -14\\f(-5) = y = -14\\\\\)

so:

x = -5

y = -14

Step-by-step explanation:

JKE and KEJ line up and are in the correct position and order to form the triangle listed by themselves. The other ones will not form even the same shape!

The reason why the other ones aren't elgible: EJR, KE and JE just form a line, and JAOE forms an uneven trapezoidal shape (forgot what it was called)

So that would leave JKE and KEJ, which are the only ones that line up.

The correct options are ΔJKE and ΔKEJ.

A and D are correct.

A triangle in geometry is a three-sided polygon with three edges and three vertices.

As per the given data:

ΔJKE:

This is correct as J, K and E are the vertices and written in the correct order.
