The strength and relationships of the given data is verified as reasonable.

Given,

Determine the degree of the link (weak, moderate, or strong) in each of the six plots and if it is reasonable to fit a linear model to the data.

(a) There is a moderate relationship in the data. A linear model should not be reasonable.

→ From the plot here, it is clear that the data is following a quadratic trend, so a linear model should not be reasonable. On the other hand, it is also clear that the data is scattered more than a little around the approximate quadratic trend line, so there is a moderate relationship in the data.

(b) There is a strong relationship in the data. A linear model should be reasonable.

→ From the plot here, it is clear that the data is following a linear trend, so a linear model should be reasonable. On the other hand, it is also clear that the data is scattered almost a little around the approximate linear trend line, so there is a strong relationship in the data.

(c) There is a weak relationship in the data. A linear model should not be reasonable.

→ From the plot here, it is clear that the data is not following any trend, so a linear model should not be reasonable. On the other hand, it is also clear that the data is scattered everywhere, so there is a weak relationship in the data.

(d) There is a moderate relationship in the data. A linear model should not be reasonable.

→ From the plot here, it is clear that the data is following a quadratic trend, so a linear model should not be reasonable. On the other hand, it is also clear that the data is scattered more than a little around the approximate quadratic trend line, so there is a moderate relationship in the data.

(e) There is a strong relationship in the data. A linear model should be reasonable.

→ From the plot here, it is clear that the data is following a linear trend, so a linear model should be reasonable. On the other hand, it is also clear that the data is scattered almost a little around the approximate linear trend line, so there is a strong relationship in the data.

(f) There is a weak relationship in the data. A linear model should not be reasonable.

The ounces of the 50% mixture that the pharmacist should use is 6 ounce.

From the information, we need two equations to solve this problem.

equation 1:

x + y = 10

equation 2:

.5x + .75y = 10(.6)

set y = 10 - x

.5x + .75(10-x) = 6

.5x + 7.5 - .75x = 6

.5x -.75x = 6 - 7.5

-.25x = -1.5

Divide

x = -1.5/-.25

x = 6

The constant of proportionality for the relationship is 0.002.

We are provided that amount of chlorine needed is directly proportional to the volume of the pool .

So we can formulate the relation as

C = kV ... (1)                   ( where  C = amount of chlorine ,

                                              k = constant of proportionality

                                              V = volume of the pool  )

the sample ratio of chlorine to the the volume of pool , we have :

5 : 2500

10 : 5000

15 : 7500

So taking the first sample value and putting it in eqn (1)

we get

5 = k (2500)

therefore,

k = 5/ 2500

k = 0.002

So the constant of proportionality will be 0.002

Similarly if we take the other values also the constant of proportionality will remain the same.

The length of the wallpaper of 27 inches wide required is  35.56 feet

The problem requires conversion of the dimensions to have similar unit

To convert 80 square feet to square inches. we multiply by 144

80 * 144 = 11520 square inches

area = length * wide

11520 = length * 27

length = 11520 / 27

length = 426.667 feet

to get the length in inches we divide the unit in feet by 12

length = 426.667 inches / 12

a) The hypothesis are given as follows:

b) The significance level is of α = 0.1.

c) The test statistic is of: t = 4.86.

d) The p-value is of: 0.

At the null hypothesis, it is tested if there is not enough evidence that the mean level is greater at the bottom of the surface, that is, if the mean is not positive, hence:

[tex]H_0: \mu_d \leq 0[/tex]

At the alternative hypothesis, it is tested if there is enough evidence that the mean level is greater at the bottom of the surface, that is, if the mean is positive, hence:

[tex]H_1: \mu_d > 0[/tex]

As stated in the problem, the significance level is of:

α = 0.1.

The test statistic is calculated by the formula presented as follows:

[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]

The variables of this formula are listed as follows:

From the table, the sample is composed by the differences and given as follows:

0.015, 0.028, 0.177, 0.121, 0.102, 0.107, 0.019, 0.066, 0.058, 0.121.

The above sample is inserted into a calculator, to obtain the parameter values given as follows:

[tex]\overline{x} = 0.0814, \mu = 0, s = 0.053, n = 10[/tex]

Hence the numeric value of the test statistic is given as follows:

t = (0.0814 - 0)/(0.053/sqrt(10))

t = 4.86.

Using a t-distribution calculator, considering a right-tailed test, as we are testing if the mean is greater than a value, with 10 - 1 = 9 df and t = 4.86, the p-value is of 0.

Answer:

Option (C)

Step-by-step explanation:

To simplify an expression, we can combine like terms. For this expression, there are two pairs of like terms, one-fourth y and five-twelfths y, and the constants negative seventeen and six.

To combine the fractions, we can find the least common denominator, twelve, so we can rewrite the fraction as three-twelfths.

Now combine the like terms to get eight-twelfths y minus eleven, which simplifies to two-thirds y minus eleven.

Vertical asymptotes is x = -4 and horizontal asymptote is y = 1

What is an Asymptote?

An asymptote is a line that a curve approaches but never touches. A line where the graph of a function converges is known as an asymptote.

There are 3 types of asymptotes.

The given expression,

f(x) = (x² - 3x) / (x² + x - 12)

First, find Horizontal asymptote

so,

Horizontal asymptote (y) = (leading coefficient of numerator) / (leading coefficient of denominator)

leading coefficient of numerator = 1

leading coefficient of denominator = 1

y = 1/1

y =1 (Horizontal asymptote)

Now, find Vertical asymptote

so, let's simplify the expression f(x) = (x² - 3x) / (x + x - 12)

f(x) = (x(x - 3) ) / (x² + 4x - 3x - 12)

f(x) = (x(x - 3) ) / (x(x + 4) - 3 (x + 4) )

f(x) = (x(x - 3) ) / ( (x -3) (x + 4) )

f(x) = x / (x + 4)

Now, put the denominator = 0

x + 4 = 0

x = -4 ( Vertical asymptote )

Hence, Vertical asymptotes is x = -4 and horizontal asymptote is y = 1
