c = price of a slice of Cheese pizza

m= price of a slice of mushroom pizza

Jack bought 3 slices of cheese pizza and 4 slices of mushroom pizza fora total cost of $12.50

3c + 4 m = 12.50

Grace bought 3 slices of cheese pizza and 2 slices of mushroom pizza for a total cost of $8.50.

3c + 2m = 8.50

We have the system of equations:

3c + 4 m = 12.50 (a)

3c + 2m = 8.50 (b)

Subtract (b) to (a) to eliminate c

3c + 4m = 12.50

-

3c + 2m = 8.50

_____________

2m = 4

Solve for m:

m = 4/2

m=2

The cost of one slice of mushroom pizza is $2

We know that the equation of a line is given by

y = mx + b,

where m and b are numbers: m is its slope (shows its inclination) and b is its y-intercept.

In order to find the equation we must find m and b.

In all cases, m is given, so we must find b.

We use the equation to find b:

y = mx + b,

↓ taking mx to the left side

y - mx = b

We use this equation to find b.

We have that the line passes through

(x, y) = (-10, 8)

and m = -1/2

Using this information we replace in the equation we found:

y - mx = b

↓ replacing x = -10, y = 8 and m = -1/2

Then, the equation of this line is:

y = mx + b,

↓

y = -1/2x + 3

Equation 1: y = -1/2x + 3

Similarly as before, we have that the line passes through

(x, y) = (-1, -10)

and m = 0

we replace in the equation for b,

y - mx = b

↓ replacing x = -1, y = -10 and m = 0

-10 - 0 · (-1) = b

↓ 0 · (-1) = 0

-10 - 0 = b

-10 = b

Then, the equation of this line is:

y = mx + b,

↓

y = 0x - 10

y = -10

Equation 2: y = -10

Similarly as before, we have that the line passes through

(x, y) = (-6, -9)

and m = 7/6

we replace in the equation for b,

y - mx = b

↓ replacing x = -6, y = -9 and m = 7/6

Then, the equation of this line is:

y = mx + b,

↓

y = 7/6x - 2

Equation 3: y = 7/6x - 2

The line passes through

(x, y) = (6, -4)

and m = does not exist

When m does not exist it means that the line is vertical, and the equation looks like:

x = c

In this case

(x, y) = (6, -4)

then x = 6

Then

Equation 4: x = 6

The line passes through

(x, y) = (6, -6)

and m = 1/6

we replace in the equation for b,

y - mx = b

↓ replacing x = 6, y = -6 and m = 1/6

Then, the equation of this line is:

y = mx + b,

↓

y = 1/6x - 7

Equation 5: y = 1/6x - 7

Answer:

5(5m + 2)

Explanation:

To factor out the expression, we first need to find the greatest common factor between 25m and 10, so the factors if these terms are:

25m: 1, 5, m, 5m, 25m

10: 1, 2, 5, 10

Then, the common factors are 1 and 5. So, the greatest common factor is 5.

Now, we need to divide each term by the greatest common factor 5 as:

25m/5 = 5m

10/5 = 2

So, the factorization of the expression is:

25m + 10 = 5(5m + 2)

the perimeter is the sum of the outside sides. So in this case is 4+4+2+2+2+2=16

so the answer is 16cm

Considering the given dot plot for the distribution, it is found that:

a) The distribution is right skewed.

b) There is an outlier at 9.

c) Since there is an outlier, the best measure of center is the median.

A dot plot shows the number of times that each measure appears in the data-set, hence the data-set is given as follows:

1, 1, 1, 1, 2, 2, 2, 2, 2 3, 3, 3, 3, 4, 4, 4, 5, 5, 5, 9.

To find the skewness of the data-set, we need to find the mean and the median.

The mean is the sum of all values divided by the number of values of 20, hence:

Mean = (4 x 1 + 5 x 2 + 4 x 3 + 3 x 4 + 3 x 5 + 9)/20 = 3.1.

The median is the mean of the 9th and the 10th elements(even cardinality) of the data-set, hence:

Median = (2 + 3)/2 = 2.5.

The mean is greater than the median, hence the distribution is right skewed.

To identity outliers, we need to look at the quartiles, as follows:

The interquartile range is:

IQR = 4 - 2 = 2.

Outliers are more than IQR from the quartiles, hence:

4 + 1.5 x 2 = 4 + 3 = 7 < 9, hence 9 is an outlier in the data-set, and hence the median will be the best measure of center.

The questions are as follows:

Part A: Describe the dotplot. (4 points)

Part B: What, if any, are the outliers in these data? Show your work. (3 points)

Part C: What is the best measure of center for these data? Explain your reasoning. (3 points) (10 points)

Let the amount of 30% acid solution be a

Let the amount of 60% acid solution be b

Given, "a" and "b" mixed together gives 570 liters of 31% acid. We can write:

Also, we know 30% acid and 60% acid amounts to 570 liters, thus:

The first equation becomes:

We can solve the second equation for a:

Putting this into the first equation, we can solve for b. The steps are shown below:

So, a will be:

a = 570 - b

a = 570 - 19

a = 551

Thus,

551 Liters of 30% acid solution and 19 Liters of 60% acid solution need to be mixed.

We have to solve for c:

When we have quadratic expressions, we have to take into account that each number has two possible square roots: one positive and one negative.

We can see it in this example: the square root of 4 can be 2 or -2. This is beacuse both (-2)² and 2² are equal to 4.

Then, taking that into account, we can solve this expression as:

We then calculate the first solution for the negative value -8:

And the second solution for the positive value 8:

Then, the two solutions are c = -17 and c = -1.

We can check them replacing c with the corresponding values we have found:

Both solutions check the equality, so they are valid solutions.

Answer: -17 and -1.

Given the equation

To apply the subtraction property of equality, we subtract 20 from both sides.

If b is a positive real number

then

a) Let's say initial population is po and p = p(t) is the function that describes that population at time t. If it increases 10% each hour then we can write:

t = 0

p = po

t = 1

p = po + 0.1 . po

p = (1.1)¹ . po

t = 2

p = 1.1 . (1.1 . po)

p = (1.1)² . po

t = 3

p = (1.1)³ . po

and so on

So it has an exponential growth and we can write the function as follows:

p(t) = po . (1.1)^t

p(t) = 500 . (1.1)^t

Answer: p(t) = 500 . (1.1)^t

b)

We want the population for t = 2 hours, then:

p(t) = 500 . (1.1)^t

p(2) = 500 . (1.1)^2

p(2) = 500 . (1.21)

p(2) = 605

Answer: the population at t = 2 hours is 605 algae.

c)

Let's plug t = 4 in our function again:

p(t) = 500 . (1.1)^t

p(4) = 500 . (1.1)^4

p(4) = 500 . (1.1)² . (1.1)²

p(4) = 500 . (1.21) . (1.21)

p(4) = 500 . (1.21)²

p(4) = 732.05

Answer: the population at t = 4 hours is 732 algae.

The amount Andrew have to pay to buy 4 pounds of walnuts = $19

This also means that the maximum height will be given as the y component of the vertex of the parabola, then if we want to find the maximum height, we need to write the function in vertex form so let's do that:

Hence the function can be written as:

and its vertex is at (1.9,19.9) which means that the maximum height of the ball is 19.9 m

We have to select a point that is the best representative of the square root of 15.

We can calculate the square root of 15 with a calculator, but we can aproximate with the following reasoning.

We know that 15 is the product of 3 and 5. If we average them, we have 4.

If we multiply 4 by 4, we get 16, that is a little higher than 15.

If we go to the previous number (3) and calculate 3 by 3 we get 9, that is far from 15 than 16.

So we can conclude that the square root of 15 is a number a little less than 4.
