Answer:

x≥14.5

Step-by-step explanation:

Length of the line AB is 1.414 units and midpoint of AB is (3.5,5.5).

Given in the graph,

A(4,6)  and B(3,5)

Distance formula = \(\sqrt{(x1-x2)^{2} +(y1-y2)^{2} }\)

                      AB =  \(\sqrt{(4-3)^{2} +(6-5)^{2} }\)

                            = \(\sqrt{1^{2} +1^{2} }\)

                            = \(\sqrt{2}\)

                            = 1.414 units

Midpoint = \((\frac{x1+x2}{2},\frac{y1+y2}{2})\)

Let midpoint of AB be C(x,y)

C = (x,y) = \((\frac{4+3}{2},\frac{6+5}{2})\)

             = \((\frac{7}{2},\frac{11}{2})\)

             = (3.5,5.5)

Hence, length is 1.414 units and midpoint is (3.5,5.5).

The cost to ship a box of 250 grams, with 10 books of weight of 8.5kg by natalie is $ 29.75.

The total weight of the books and the box is:

10 books × 810 grams/book + 250 grams = 8,250 grams + 250 grams = 8,500 grams

To convert this to kilograms, we divide by 1000:

8,500 grams ÷ 1000 = 8.5 kg

The cost of shipping will be based on the weight, so we can multiply the weight in kilograms by the shipping cost per kilogram:

8.5 kg × $3.50/kg = $29.75

A horizontal line has slope zero since it does not rise vertically (i.e. y1 − y2 = 0), while a vertical line has undefined slope since it does not run horizontally (i.e. x1 − x2 = 0). because division by zero is an undefined operation.

If $550 is deposited in an acount paying 8.6% annual interest, compounded semiannually the account will take approximately 5.2 years to increase to $850.

To calculate the time it takes for the account to increase to $850, we can use the formula for compound interest:

\(A = P(1 + r/n)^{(nt)\)

Where:

A is the final amount ($850),

P is the initial deposit ($550),

r is the annual interest rate (8.6% or 0.086),

n is the number of times the interest is compounded per year (semiannually, so n = 2),

and t is the time in years.

Rearranging the formula to solve for t, we have:

t = (1/n) * log(A/P) / log(1 + r/n)

Plugging in the values, we get:

t = (1/2) * log(850/550) / log(1 + 0.086/2)

Calculating this expression gives us approximately 5.2 years, rounded to the nearest tenth. Therefore, it will take around 5.2 years for the account to increase to $850.

To determine whether the given vectors V1, V2, and Vz are linearly independent, we can set up a system of linear equations using these vectors and solve for the coefficients. If the system has a unique solution where all coefficients are zero, then the vectors are linearly independent. Otherwise, if the system has non-zero solutions, the vectors are linearly dependent.

Let's set up the system of linear equations using the given vectors V1, V2, and Vz:

x * V1 + y * V2 + z * Vz = 0

Substituting the values of the vectors:

x * (11, -3) + y * (1, -3, 1) + z * (-3, 1, 1) = (0, 0)

Expanding the equation, we get three equations:

11x + y - 3z = 0

-3x - 3y + z = 0

-x + y + z = 0

We can solve this system of equations to find the values of x, y, and z. If the only solution is x = y = z = 0, then the vectors V1, V2, and Vz are linearly independent. If there are other non-zero solutions, then the vectors are linearly dependent.

By solving the system of equations, we can determine the nature of the vectors.

The statement that shows a discrepancy between the check register and bank statement is: C. Gavin: The balance in his check register is $500 and the balance in his bank statement is $510.

The check register shows a balance of $500, while the bank statement shows a balance of $510.

In the case of Gavin, where the balance in his check register is $500 and the balance in his bank statement is $510, there is a $10 discrepancy between the two.

A possible explanation for this discrepancy could be outstanding checks or deposits that have not yet cleared or been recorded in either the check register or the bank statement.

For example, Gavin might have written a check for $20 that has not been cashed or processed by the bank yet. Therefore, the check register still reflects the $20 in his balance, while the bank statement does not show the deduction. Similarly, Gavin may have made a deposit of $10 that has not yet been credited to his account in the bank statement.

The range of the possible values of r^2 is 0 to 1. It represents the proportion of the dependent variable’s variance that can be explained by the independent variable(s).


The coefficient of determination, often denoted as r^2, measures the proportion of the dependent variable’s variance that can be explained by the independent variable(s) in a statistical model. The value of r^2 ranges from 0 to 1.
A value of 0 for r^2 indicates that the independent variable(s) does not explain any of the variance in the dependent variable. On the other hand, a value of 1 implies that the independent variable(s) fully explain the observed variance in the dependent variable.
Therefore, the range of the possible values of r^2 is 0 to 1. Any positive numerical value within this range indicates a degree of explanatory power, while values outside this range are not meaningful in the context of r^2. It serves as a useful tool for assessing the strength of a statistical relationship and the predictive ability of a model.

If Jay spends 40 at the store, the number of points he will earn is; 10 points

Let the number of rewards points a customer earns be y

Let the amount of money, in dollars, that the customer spends at the store be x.

Since the number of rewards points a customer earns varies directly with the amount of money, in dollars, that the customer spends at the store, then we can say that;

y ∝ x

Thus;

y = kx

where k is the constant of proportionality.

We are given x = 15 when y = $60. Thus;

60 = 15k

k = 60/15

k = 4

Answer:

0.4032

Step-by-step explanation:

First, we find the z score of the higher given number (20.6)

z-score equation:

z =  (x – μ)  
          σ

In this case, x is 20.6, μ is 20.6, and σ is 2

20.6-20.6=0

0/2 = 0

0 on a z score table is 0.5000

Next, we find the z-score of the lower given number (18)

μ is still 20.6 and σ is still 2

18-20.6 = -2.6

-2.6 / 2 = -1.3

-1.3 on a z-score table is 0.0968

Finally, we subtract our two z-scores

0.5000 - 0.0968 = 0.4032

Answer: 0.4032

The proportion of 0.4032 of temperatures are between 18°C and 20.6°C.

A Z-score is a metric that quantifies how closely a value relates to the mean of a set of values.

Standard deviations from the mean are used to measure Z-score. A Z-score of zero means the data point's score is the same as the mean score.

First, we find the z score of the higher given number (20.6)

z-score formula:

z =  (x – μ)/ σ

In this case, x is 20.6, μ is 20.6, and σ is 2

So z = (20.6-20.6) / 2

        =0/2 = 0

0 on a z score table is 0.5000.

Next, we find the z-score of the lower given number (18)

μ is still 20.6 and σ is still 2

18-20.6 = -2.6

-2.6 / 2 = -1.3

-1.3 on a z-score table is 0.0968

Finally, we subtract our two z-scores

0.5000 - 0.0968 = 0.4032

Therefore, the proportion of 0.4032 of temperatures are between 18°C and 20.6°C.

The question asks to identify the quadrant in which an angle in standard position lies.

When an angle is in standard position, it means that its initial ray coincides with the positive x-axis, and the terminal ray determines the angle's position. The position of the terminal ray relative to the axes determines the quadrant in which the angle lies. In Quadrant I, the angle measures between 0 and 90 degrees, with both the x and y coordinates being positive. In Quadrant II, the angle measures between 90 and 180 degrees, with the x coordinate being negative and the y coordinate being positive. In Quadrant III, the angle measures between 180 and 270 degrees, with both the x and y coordinates being negative. In Quadrant IV, the angle measures between 270 and 360 degrees, with the x coordinate being positive and the y coordinate being negative. By examining the signs of the x and y coordinates, we can determine the specific quadrant in which the angle lies.

The probability of getting a score of 80% or higher is 0.18750.

We are given that;

The probability of getting a score = 80%

Now,

We can use the binomial probability formula:

\($$P(X) = {n \choose x} p^x (1-p)^{n-x}$$\)

where P(X) is the probability of getting x successes out of n trials, p is the probability of success on each trial and (1-p) is the probability of failure on each trial.

In this case, we have:

n = 5 the number of questions on the quiz

x = 4 or x = 5, the number of correct answers needed to get 80% or higher

p = 0.5, the probability of guessing correctly on each question

(1-p) = 0.5, the probability of guessing incorrectly on each question

So, we can plug these values into the formula and calculate the probabilities for x = 4 and x = 5:

\($$P(X=4) = {5 \choose 4} (0.5)^4 (0.5)^{5-4} = \frac{5!}{4!(5-4)!} (0.5)^4 (0.5)^1 = \frac{5}{1} (0.0625) (0.5) = 0.15625$$$$P(X=5) = {5 \choose 5} (0.5)^5 (0.5)^{5-5} = \frac{5!}{5!(5-5)!} (0.5)^5 (0.5)^0 = \frac{1}{1} (0.03125) (1) = 0.03125$$\)

To find the probability of getting 80% or higher, we need to add these two probabilities:

\($$P(X \geq 4) = P(X=4) + P(X=5)\)

= 0.15625 + 0.03125 = 0.18750$$

Therefore, by probability the answer will be 0.18750.

The Inequality notation of the given equation 10+3x>-16 is x > -2

What is Inequality notation?

A mathematical statement known as an inequality expresses the relationship between two quantities while indicating that they are not completely equal. The four symbols used to represent inequality are. ≥, >,<, and ≤.

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare the two values in inequality. Less than (or less than and equal to), greater than (and greater than or equal to), and also not equal to signs are used in place of the equal sign.

Consider the above equation.

-10 +3x > -16

Add 10 on both sides.

= -10+3x+10> -16+10

= 3x> -6

Divide by 3 to equation into both sides.

= \(\frac{3x}{3} > \frac{-6}{3}\)
