The linear function of the table is a) g(x)=x-7
What is linear function?
If the largest power of the variables in a function is 1, then that function is linear. A line across these two points with a straightedge is needed to complete the graph because two points determine a line. When m and b are real numbers, the slope of a linear function has the form f(x)=mx+b. To find the x-intercept, set f(x)=0 and solve for x. Because y=f(x), we can use y and f(x) interchangeably.
Here let us take g(x) as y values. In given table take any two points ,
[tex](x_1,y_1)=(0,-7)\\(x_2,y_2)=(2,-5)[/tex]
Now using slope formula ,
=> slope m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
=> slope m = 2/2 = 1
Now using equation formula,
=> [tex]y-y_1=m(x-x_1)[/tex]
=> y+7=1(x-0)
=> y+7=x
=> y =x-7
Then y=g(x)
=> g(x) = x-7
Therefore the linear function of the given table is g(x)=x-7 .

We are told that the equation that models the concentration in parts per million of a type of antibiotic in a human's bloodstream after h hours is;
A(h) = -0.06h² + 2h + 4
where h is the time in number of hours after which the concentration is recorded.
Now, we want to find the concentration after 4 hours and as such we will input 4 for h in the equation to get;

A percentage is a certain number or part in every hundred. It is a fraction with the denominator 100, and the symbol for it is "%." Finding the percentage of a whole in terms of 100 is what percentage calculation refers to. Two methods exist for calculating a percentage. By adjusting the fraction's denominator to 100 and applying the unitary approach.
We are given that Landyn's current monthly net pay is $560
And he does not wish to spend more than 10% of his current net pay
That means not more that $56
Now we are given 3 choices
Out of which the third one is more than 60 hence this rules out the third option. Now the first option the value is 55+55(0.005) which again is more than $56
Consider the option B)
50 + 50(0.05)
= 52.5
Which is less than $56
Hence, The plan that fits to Landyn's budget is plan B

A boat sails 285 miles south and then 132 miles west. What is the magnitude of the boats resultant vector?
Answers
The magnitude of the boats resultant vector is 314.1 mi
What is a vector?A vector is a physical quantity that has both magnitude and direction.
What is a resultant vector?A resultant vector is the sum of two or more vectors.
How to find the boats resultant vector?Since the boat sails 285 miles south and then 132 miles west, we have that its first direction vector is r = (285 mi)j. Also, its direction vector west is r' = -(132 mi)i
So, the resultant vector R = r + r'
= (285 mi)j + (132 mi)i
= (132 mi)i + (285 mi)j
So, the magnitude of the resultant vector is R = √(r² + r'²)
So, substituting thevalues of the variables into the equation, we have
R = √(r² + r'²)
R = √((285 mi)² + (132 mi)²)
R = √(81225 mi² + 17424 mi²)
R = √(98649 mi²)
R = 314.08 mi
R ≅ 314.1 mi
So, the resultant vector is 314.1 mi

What is slope?A line's steepness can be determined by looking at its slope.
Slope is determined mathematically as "rise over run" (change in y divided change in x).
assuming slope is m
m = (y₂ - y₁) / (x₂ - x₁) = change in y / change in x
considering the formula
slope is between 0 and 1 when rise (change in y) is so smaller than run (change in x) hence the line is closer to horizontal
slope is greater than 1 then the rise is more than run, in this case the line is approaching vertical line
numbers less than zero are negative hence slope has a negative value
A horizontal line is a line that has a slope of of zero while vertical lines has its slope as infinity

Josephine invests £3,500 in a bank account which pays annual compound interest of 4.5%. How much money will she have in the bank after: (a) 2 years, (b) 3 years?
Answers
Josephine have £3882.9 amount after 2 years and £3994.9 amount after 3 years.
Using the formula of compound interest we can find the amount after t years compounded annually at the r per cent rate.
The formula of compound interest is as follows,
[tex]A=p(1+\frac{r}{100} )^t[/tex]
Where P is the principal value, A is the amount, r is the rate and t is the time.
Here we have a principal value of £3,500 and a rate is 4.5%.
Now, finding the amount after 2 years by putting the values in the formula of compound interest,
[tex]A=p(1+\frac{r}{100} )^t\\\\A=3500(1+\frac{4.5}{100} )^2\\\\A=3500(1+0.045 )^2\\A=3500(1.045)^2\\A=3500\times1.092025\\A=3882.0875[/tex]
So, After 2 years Josephine will have £3882.9.
Now, finding the amount after 3 years,
[tex]A=p(1+\frac{r}{100} )^t\\\\A=3500(1+\frac{4.5}{100} )^3\\\\A=3500(1+0.045 )^3\\A=3500(1.045)^3\\A=3500\times1.141166125\\A=3994.0814375[/tex]
So, After 3 years Josephine will have £3994.9.
Therefore, After 2 years Josephine will have £3882.9 and after 3 years Josephine will have £3994.9 when 4.5% interest is compounded annually.

Quantity = 40 ounces
cost/quantity = 14.99/40 = 0.374 dollar/ounce
For Brand B
Cost = $19.99
Quantity = 50 ounces
cost/quantity = 19.99/50 = 0.399 dollar/ounce
For Brand C
Cost = $21.99
Quantity = 1/2 gallon = 64 ounces

If 202 are sampled, what is the probability that the sample proportion will differ from the population proportion by greater than 0.03? Round your answer to four decimal places.
Answers
The probability that the sample proportion of the number of people using the courier will differ from the population proportion by greater than 0.03 is 0.0504
How to get the required probabilityThe probability is calculated using z score, this is used to determine the amount of standard deviations a sample, X is from the mean
The z score is given by the formula
z = (X - μ) / σ
Definition of variables
mean, μ = p = 0.05
sample size, n = 202
standard deviation, σ
= √{(p(1 - p)) / n}
= √{(0.05(1 - 0.05)) / 202}
= √{(0.05 * 0.95) / 202}
= 0.01533
The probability
differ from the population proportion by less than 3%
|X - 0.05| > 0.03
X < 0.02 OR X > 0.08
P(z < 0.02) + P(z > 0.08 )
z score for z < 0.02
z = (0.02 - 0.05) / 0.01533
= -1.9569
p value for z < -1.9569 = 0.02518
z score for z > 0.08
z = (0.08 - 0.05) / 0.02196
= 1.9569
p value for z > 1.9569 = 1 - 0.9748 = 0.02518
The probability required = 0.02518 + 0.02518 = 0.0504 = 5.04%
