Step-by-step explanation:

The equation for the purchase of n number of notebooks by Caitlin is

4n = c , where c is representing the cost that Caitlin paid.

The unitary approach is a strategy for problem-solving that involves first determining the value of a single unit, then multiplying that value to determine the required value.

Finding the value of a single unit using the unitary technique allows us to determine the value of the necessary number of units based on this value.

the price for one notebook was = $4 each

n number of notebooks were purchased by caitlin

therefore the cost price of 4 notebooks will be = 4 * n

as per given in the question cost price = c

therefore the equation formed will be

4n = c

The graph of the quadratic equation:

y = x^2 -8x + 16

Can be seen in the image at the end.

First, we have a quadratic function:

y = x^2 -8x + 16

To graph this we need to find some points on the parabola, to do that, we will evaluate it in some values of x.

if x = 0

y = 0^2 - 8*0 + 16 = 16

So we have the point (0, 16)

if x = 1

y = 1^2 - 8*1 + 16 = 9

So we have the point (1, 9)

if x = -1 we have:

y = (-1)^2 - 8*-1 + 16 = 23

So we have the point (-1, 23)

And so on, once you have enough points, you can graph them in a coordinate axis and then draw a parabola that connects them, the graph of the quadratic equation can be seen in the image below.

Answer: there is no picture again. just take a good guess

Step-by-step explanation:

The value of x and y in the angles are 15.6 and 10.5 respectively.

When parallel lines are cut by a transversal lines, angle relationships are formed such as corresponding angles, alternate angles, linear angles, vertically opposite angles etc.

Therefore, line XD, TZ, YF and LP are parallel to each other.

WC is the transversal line.

Hence,

m∠CNL = 6x - 17.6

m∠FBH = 12y - 22

m∠THR = 3x + 29.2

Hence,

180 - (12y - 22) = 6x - 17.6(corresponding angles)

Corresponding angles are congruent

180 - 12y + 22 = 6x - 17.6

6x + 12y = 180 + 22 + 17.6

6x + 12y = 219.6

Therefore,

180 - (3x + 29.2) = 12y - 22 (alternate angles)

Alternate angles are congruent .

180 - 3x - 29.2 = 12y - 22

180 + 22 - 29.2 = 12y + 3x

172.8 = 3x + 12y

combine the equation

6x + 12y = 219.6

3x + 12y = 172.8

subtract equation(ii) from equation(i)

3x = 46.8

x = 46.8 / 3

x = 15.6

12y = 219.6 - 6(15.6)

12y = 219.6 - 93.6

12y = 126

y = 126 / 12

y = 10.5

Therefore,

x = 15.6

y = 10.5

The customer can purchase 1.19788 pounds of cheese (approximately 1.2 pounds).

We are given with the cost of ham is $2.49 per pound and

Cost of swiss cheese is $3.79 per pound.

So, the cost of 2 pounds of ham will be given as-

= 2× $2.49

= $4.98

Since, the customer has a total of  $9.50 to spend on 2 pounds of ham and some cheese,

∴ Let the number of pounds of cheese she can purchase be x.

Then the equation will be this:

2.49*2 + 3.79*x = 9.50

4.98 + 3.79x = 9.50

Subtracting 4.98 from each side we get-

4.98 -4.98 + 3.79x = 9.50-4.98

3.79x = 4.54

x  [tex]=\frac{4.54}{3.79}[/tex]

If a circle has a circumference of 320 cm, then its radius can be calculated as 50.92 cm according to the formula of circumference of a circle.

In geometry, the circumference can be defined as the perimeter of a circle or an ellipse. It can also be said as the linear distance present around it.

To better describe it, you can imagine that if a circle is opened out and placed as a straight line, then the total length of that straight line can be described as the circumference of the circle.

It is synonymous to perimeter, but the terminology can only be used with circled and ellipses. It is the curved length of the object. In this case, the object is mostly 2 dimensional but sometimes 3 dimensional objects can also be placed to take out their circumference with other methods.

In this particular question,

2[tex]\pi[/tex]r = 320

⇒ r = 320/2[tex]\pi[/tex]

⇒ r = 50.92

⇒ r ≈ 51 cm

59.25 euros is the the total cost of the cans of weedkiller needed to cover the lawn

A trapezium is a convex quadrilateral with exactly one pair of opposite sides parallel to each other

The figure that is formed is the following with the respective measurements, now to calculate the area we need the height, for Pythagoras we have:

17 ²= h ² + 8 ²

h ² = 289 - 64

h ² = 225

h = 15

now the figure area is as follows:

A = h × (b + a) / 2

b long side 20 m and short side 12 cm, replacing:

A = 15 × (12 + 20) / 2

A = 240 m²

We are told that each can of weed killer can cover up to 100m ^ 2

Thus:

240/100 = 2.4, so you would need 3 cans of weedkiller

each can costs 19.75, which means that the total cost is:

Applying logarithm properties, the solution of the highlighted question is given as follows:

x = 4.

The logarithmic equation is given as follows:

[tex]\log_{a}(x + 2) = \frac{1}{3}\log_{a}{8} + \log_{a}{3}[/tex]

First, we apply the power rule, meaning that the multiplying coefficient of the logarithm can be the power of the given term, hence:

[tex]\frac{1}{3}\log_{a}{8} = \log_{a}{8^{\frac{1}{3}}} = \log_{a}{\sqrt[3]{8}} = \log_{a}{2}[/tex]

Then the equivalent expression is:

[tex]\log_{a}(x + 2) = \log_{a}{2} + \log_{a}{3}[/tex]

Now we apply the product rule, as the sum of two logarithms of same base can be written as a single logarithm, keeping the base and multiplying the terms.

Hence the equivalent expression is:

[tex]\log_{a}(x + 2) = \log_{a}{(2 \times 3)}[/tex]

[tex]\log_{a}(x + 2) = \log_{a}{6}[/tex]

The logarithm function is one-to-one, meaning that if they have the same input, they will have the same output, hence we can solve for x as follows:

Since X² (68.732) > X²₀.₀₁ (13.277), we reject the null hypothesis and conclude that There is evidence that political views and level of marijuana usage are related.

The alternative hypothesis states that political beliefs and marijuana use depend on one another within the population, contrary to the null hypothesis that asserts these two variables are independent.

H₀ : Pij = Pi · Pj ; i = 1, 2, 3 ; j = 1, 2, 3

Ha : at least one Pij ≠ Pi · Pj

We want to test whether there is a relationship between political views and marijuana usage levels. The results of a random sample of size n = 1353 are derived from the following formula;

e = (Row total) x (Column total) /Total sample size

We are told to use the 0.01 level of significance to test the null hypothesis. Thus, α = 0.01. The table has r = 3 rows and c = 3 columns. An r × c table has degrees of freedom df = (r - 1) x (c - 1). So, a 3×3 table has degrees of freedom df = (3 - 1) x (3 - 1) = 4. From formula the df = 4 and α = 0.01, χ²₀.₀₁ = 13.277. Reject the null hypothesis if X² ≥ 13.277 where

x² =Σ(a - e)²/e

Substituting the observed and expected frequencies summarized in the table above into the formula for x², we get

X² = 68.732

Rejection Region → X² ≥ 13.277

Test statistic → X² = 68.732

Since X² (68.732) > X²₀.₀₁ (13.277), we reject the null hypothesis and conclude that There is evidence that political views and level of marijuana usage are related.

The ratio of x:y  is 4:3.

Comparing two amounts of the same units and determining the ratio tells us how much of one quantity is in the other. Two categories can be used to categories ratios. Part to whole ratio is one, while part to part ratio is the other. The part-to-part ratio shows the relationship between two separate entities or groupings.

For instance, a class has a 12:15 boy-to-girl ratio, but the part-to-whole ratio refers to the relationship between a particular group and the entire. For instance, five out of every ten people enjoy reading. As a result, the ratio of the portion to the total is 5: 10, meaning that 5 out of every 10 persons enjoy reading.

Given:

15% of x=20% of y

So,

15 / 100 × x = 20 / 100 × y

3 / 20x = 1/5y

x / y = 1/5 x 20/3
