Answer:
£2,450
Step-by-step explanation:
What we want to do here is calculate the total amount spent on his birthday in £
We already have some costs in pounds, it is the costs not in pounds we are converting.
Flights already in pounds, no conversion
Hotel $105 per night at 14 days
Total here is 14 * 105 = $1470
Wifi cost at $4 per day for 13 days
Total here is 13 * 4 = $52
Total amount spent in dollars alone is $1470 + $52 = $1522
We try and covert this to pounds
$1.45 = £1
$1522 = £x
We simply cross multiply at this point
x = 1522/1.45 = 1049.65 which is approximately £1050
Total amount spent in £ is thus 1050 + 1400 = £2,450
Answer:
£2449.65
Step-by-step explanation:
105 × 14 = $1470
1470 ÷ 1.45 = £1013.79
13 × 4 = $52
52 ÷ 1.45 = £35.86
£1013.79 + £35.86 = £1049.65
£1049.65 + 1400.00 = £2449.65
The total cost was £2449.65

Alberto started out bench pressing 60 pounds. He then added 5 pounds every week. Determine whether the situation is linear or nonlinear, and proportional or nonproportional
Answer
linear
nonproportional
Step-by-step explanation:
Since for each equal change in time (1 week), there is an equal change in weight (5 lb), the situation is linear.
At time zero, the first week, the weight was not zero. It was 60 lb, so it is not proportional.
Answer:
linear

In a multiple regression model, the error term e is assumed to
a. have a mean of 1
b. have a variance of zero
c. have a standard deviation of 1
d. be normally distributed
In a multiple regression model, the error term e is assumed to be normally distributed. This means that option (d) "be normally distributed" is the correct answer.
In multiple regression, the error term (also known as the residual) represents the discrepancy between the observed values and the predicted values of the dependent variable. It captures the unexplained variation in the data.
The assumption of normal distribution for the error term is a fundamental assumption in multiple regression analysis. It implies that the errors follow a normal distribution with a mean of zero and a constant variance. This assumption allows for the use of statistical inference techniques and hypothesis testing based on the properties of the normal distribution.
Therefore, in a multiple regression model, the error term e is assumed to be normally distributed, which aligns with option (d) as the correct answer.

17. Modeling With Mathematics Three orders are placed at a pizza shop. Two small pizzas, a liter of soda, and a salad cost $14: one small pizza, a liter of soda, and three salads cost $I5, and three small pizzas, a liter of soda, and two salads cost $22. How much does each item cost?
First we notice that in each order, they place the same items from the menu. Let them be
\(\begin{gathered} x\rightarrow small\text{ pizza} \\ y\rightarrow liter\text{ of soda} \\ z\rightarrow salad \end{gathered}\)For the first order we know that they ordered 2 small pizzas, a liter of soda and a salad and that it cost 14 dollars. We can write this like
\(2x+y+z=14\)For the second order we have one small pizza, a liter of soda and three salads. That cost 15 dollars. Then
\(x+y+3z=15\)Finally, the last order was three pizzas, a liter of soda and two salads all this with a cost of 22 dollars, so
\(3x+y+2z=22\)Then, from the data we have the following system of equations
\(\begin{gathered} 2x+y+z=14 \\ x+y+3z=15 \\ 3x+y+2z=22 \end{gathered}\)Once we solve this system we can know how much each item cost. To solve, first we are going to solve the first equation for z. Then
\(\begin{gathered} 2x+y+z=14 \\ z=14-2x-y \end{gathered}\)Then we plugg this value of z in the other two equations. Then
\(\mleft\{\begin{aligned}x+y+3z=15 \\ 3x+y+2z=22\end{aligned}\rightarrow\mleft\{\begin{aligned}x+y+3(14-2x-y)=15 \\ 3x+y+2(14-2x-y)=22\end{aligned}\mright.\mright.\)Simpligying our new equations we have
\(\begin{gathered} x+y+42-6x-3y=15 \\ 3x+y+28-4x-2y=22 \\ ---------------------------- \\ -5x-2y=15-42 \\ -x-y=22-28 \\ ----------------------------- \\ 5x+2y=27 \\ x+y=6 \end{gathered}\)Now we have another system of equations, but in this case we only have two equations for two variables.
To solve this new system we solve the second equation for y,
\(y=6-x\)Then we plug the value of y in the first equation of our second system
\(5x+2(6-x)=27\)Solving for x, we have
\(\begin{gathered} 5x+2(6-x)=27 \\ 5x+12-2x=27 \\ 3x=27-12 \\ 3x=15 \\ x=\frac{15}{3} \\ x=5 \end{gathered}\)Now that we have tha value of x, we can find the value of y from
\(\begin{gathered} y=6-x \\ y=6-5 \\ y=1 \end{gathered}\)Finally, we can know the value of z from
\(\begin{gathered} z=14-2x-y \\ z=14-2(5)-1 \\ z=14-10-1 \\ z=3 \end{gathered}\)Therefore the pizza cost 5 dollars, the liter of soda 1 dollar and the salads 3 dollars.
if the equation y=1/160x^2 models a solar cooker, how many inches from the vertex (0,0) should the bracket be placed
The bracket should be placed 40 inches away from the vertex (0,0) looking at the equation y=1/160x^2 models a solar cooker.
How do you solve the inches looking at the equation y=1/160x^2?The equation with a vertex is : y = ax²
We know that the focus of a parabola is normally at the point (h, k + p), where (h, k) is the vertex of the parabola and 'p' is the distance between the vertex and the focus.
Since the vertex at the origin is (0,0), the parabolic equation then becomes;
y = (1/4p)x²
1/4p = 1/160
4p = 160

The upper bound of the p-value for the given test is 0.109.
What is the maximum possible p-value for the given test with an upper bound of 0.109?In hypothesis testing, the p-value represents the probability of obtaining a test statistic as extreme as the one observed, assuming that the null hypothesis is true. It provides a measure of the strength of evidence against the null hypothesis. In this case, we are given the null hypothesis H0: μ = 7 and the alternative hypothesis HA: μ > 7, where μ represents the population mean.
To find the p-value, we compare the test statistic with a t-distribution table or calculator. The test statistic, denoted as f, has a t-distribution with n - 1 degrees of freedom, where n is the sample size. In our case, n = 17.
Using the appropriate table or calculator, we find that the t-value corresponding to an upper bound of 0.109 is approximately 1.337 (assuming a one-tailed test). This means that the observed test statistic of 1.1 falls within the acceptance region, and the evidence against the null hypothesis is not strong enough to reject it at the given significance level.
In summary, the p-value for the given test is bounded above by 0.109, indicating that the observed data do not provide strong evidence to reject the null hypothesis. It is important to note that hypothesis testing is just one tool in statistical analysis, and other factors such as sample size, effect size, and contextual considerations should be taken into account when drawing conclusions from the results.

Find the shortest distance from the point (2,0,-3) to the plane x+y+z=1
Shortest distance from the point (2, 0, -3) to the plane x + y + z = 1 is √3 units.
How to find the shortest distance from a point to a plane?To find the shortest distance between a point and a plane, we can use the formula:
distance = |ax + by + cz + d| / √(a² + b² + c²)
where a, b, and c are the coefficients of the plane's equation, d is the constant term, and (x, y, z) is the coordinates of the point.
In this case, the plane is x + y + z = 1, so a = 1, b = 1, c = 1, and d = -1. The point is (2, 0, -3), so x = 2, y = 0, and z = -3. Plugging in these values, we get:
distance = |1(2) + 1(0) + 1(-3) - 1| / √(1² + 1² + 1²)
= 3 / √3
= √3
Therefore, the shortest distance from the point (2, 0, -3) to the plane x + y + z = 1 is √3 units.

The system of inequalities did not have any solution, but after reversing the sign we will get a solution of the system of inequalities.
The inequalities are : y > 2x + 2/3 and y < 2x + 1/3
There is no intersection and no solution to the system since the region above the line y = 2x + 2/3 and the region below the line y = 2x + 1/3, respectively, are the solutions to the inequality y > 2x + 2/3 and y <2x + 1/3, respectively.
Now when the signs are changed we get:
y < 2x + 2/3 and y > 2x + 1/3
The region below the line y = 2x + 2/3 is the solution of the inequality
y= 2x + 2/3, and the region above the line y = 2x + 1/3 is the solution of the inequality y > 2x + 1/3. This implies that the area between the two lines is where the system's solution lies.

Solve the inequality. Suggestion: A calculator may be useful for approximating key numbers. 4(x^2-5) - (x^2 - 5)^2 > -12
The solution of the given inequality 4(x² - 5) - (x² - 5)² > -12 is x ≥ √3 or x ≤ -√3.
The given inequality is 4(x² - 5) - (x² - 5)² > -12. In order to solve the given inequality, first, we will multiply (x² - 5)² by -1 to get rid of the squared term. Next, we will simplify the terms by using the distributive property. Then, we will collect the like terms and solve the inequality.
Multiply (x² - 5)² by -1. => -(x² - 5)² = -x⁴ + 10x² - 25
Now, the given inequality is:
4(x² - 5) - (x² - 5)² > -12
4(x² - 5) + x⁴ - 10x² + 25 > -12
Simplify the terms by using the distributive property:
4x² - 20 + x⁴ - 10x² + 25 > -12
Simplifying further:
x⁴ - 6x² + 13 > 0
Collect like terms and solve the inequality:
(x² - 3)² + 4 > 0
As the square of any number is always greater than or equal to 0, so
(x² - 3)² ≥ 0 ⇒ (x² - 3)² + 4 ≥ 4
Hence, x² - 3 ≥ 0 ⇒ x² ≥ 3 ⇒ x ≥ ±√3
Therefore, the solution of the given inequality is x ≥ √3 or x ≤ -√3.

Error bars are graphical representations of data variability that are used to indicate the error or uncertainty in a reported measurement on graphs.
The estimated error in a measurement is indicated by error bars. In other words, an error bar represents the degree of uncertainty in a value.
When the standard deviation error bars overlap significantly, it is an indication that the difference is not statistically significant. To reach a conclusion, you must conduct a statistical test.
When the standard deviation error bars overlap even less, it indicates that the difference is unlikely to be statistically significant.

The difference between two positive integers is 4. The sum of the larger and the square of the
smaller is 24. Find the integers.
If the difference between two positive integers is 4. The sum of the larger and the square of the smaller is 24, then The two positive integers are 4 and 8.
Let the two positive integers be x and y, where x is the smaller integer and y is the larger integer.
From the problem statement, we know that:
y - x = 4 (equation 1)
\(y + x^2 = 24\) (equation 2)
We can solve for y in equation 1:
y = x + 4
Substituting this expression for y into equation 2, we get:
\(x^2 + (x + 4) = 24\)
Simplifying and rearranging, we get:
\(x^2 + x - 20 = 0\)
We can factor this quadratic equation as:
(x - 4)(x + 5) = 0
So, x = 4 or x = -5. Since x has to be a positive integer, we can ignore the negative solution and conclude that:
x = 4
Substituting this value for x into equation 1, we get:
y - 4 = 4
So, y = 8
