Which inequality represents all the values of x for y<(or equal to)-6(x-18)-2 when y=46

Answer: 12 miles

Step-by-step explanation:

Let y represent the cost and x represent the number of miles!

y = 1.25x + 3

Now put the $18 in for y

18= 1.25x + 3

15 = 1.25x

x = 12 miles

Answer:

Step-by-step explanation:

We can model the cost of a taxi trip with y = 1.25x + 3, where y is the total cost and x is the miles traveled. $1.25 is charged per mile, and the initial $3 is added to find the total cost. We know that the total cost is $18, so we can put 18 in for y and solve for x:

18 = 1.25x + 3

15 = 1.25x (subtracted 3 from both sides)

12 = x (divided each side by 1.25)

So, the trip was 12 miles

The mean can only be used with interval/ratio level data.

what is  ratio data ?

Ratio data is a form of quantitative (numeric) data. It measures variables on a continuous scale, with an equal distance between adjacent values. While it shares these features with interval data (another type of quantitative data), a distinguishing property of ratio data is that it has a 'true zero.

What are mean , median and mode?

The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set. The median is the middle value when a data set is ordered from least to greatest. The mode is the number that occurs most often in a data set.

Hence, the mean can only be used with interval/ratio level data.

The probability that the ladybug will be at position 1 at time t+1 is ((1/2)*(12/50) + (1/2)*(16/50)) = 14/50 = 0.28.

Information on possibility of occurrence is provided by probability. For instance, meteorologists can forecast the likelihood of rain by looking at weather patterns. Probability theory is utilized in epidemiology to comprehend how exposures and the risk of health impacts are related.

The probability is computed by dividing the total number of outcomes by the number of possible ways the event could occur. Probability and odds are two separate ideas. Odds are calculated by dividing the likelihood that something will occur by the likelihood that it won't.

The system of equations representing the charges for plans A and B include the following:

y = 0.2x - 50

y = 0.3x - 105

A graph of the system of equations for plans A and B are shown in the image attached below.

In order to write the system of equations representing the charges, we would have to calculate the slope of the line based on the data points described above for each plans.

Mathematically, the slope of a straight line can be calculated by using this formula;

Slope, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope, m = (y₂ - y₁)/(x₂ - x₁)

Slope, m = (66 - 50)/(580 - 500)

Slope, m = 16/80

Slope, m = 0.2

At point (500, 50), a linear equation for plan A can be calculated by using the point-slope form:

y - y₁ = m(x - x₁)

Where:

Substituting the given points into the point-slope form formula, we have;

y - 50 = 0.2(x - 500)

y - 50 = 0.2x - 100

y = 0.2x - 100 + 50

y = 0.2x - 50.

For plan B, the slope is as follows;

Slope, m = (y₂ - y₁)/(x₂ - x₁)

Slope, m = (69 - 45)/(580 - 500)

Slope, m = 24/80

Slope, m = 0.3

At point (500, 45), a linear equation for plan B can be calculated by using the point-slope form:

y - y₁ = m(x - x₁)

y - 45 = 0.3(x - 500)

y - 45 = 0.3x - 150

y = 0.3x - 150 + 45

y = 0.3x - 105.

These tables show the monthly charges for plans A and B when different numbers of messages are sent. Plan A Cell Phone Charges

Phone plans A and B each have a different flat monthly rate for the first 500 text messages and a different constant rate for every additional message over 500.

Plan A charges $50 monthly for 500 text messages and $66 monthly for 580 text messages.

Plan B charges $45 monthly for 500 text messages and $69 monthly for 580 text messages.

Letting x represent the number of messages over 500, and y the total monthly charges, write equations representing the charges for plans A and B. Then graph the equations for plans A and B on the same coordinate grid.

The value of a for which v is a linear combination is given as follows:

a = -8.

How to obtain the value of a?

A vector generated by adding two or more vectors (with various orientations) and multiplying by scalar values is known as a linear combination of two or more vectors.

v will be a linear combination of the set H if it can be obtained as the solution of a system of equations from the set H.

From the vectors, the system is defined as follows:

-x = -1.

2x - y = 4.

5x + 4y - 3z = -6.

-x + 3y - z = a.

From the first equation, the value of x is obtained as follows:

-x = -1

x = 1.

From the second equation, the value of y is obtained as follows:

2x - y = 4

2 - y = 4

y = 2 - 4

y = -2.

From the third equation, the value of z is obtained as follows:

5x + 4y - 3z = -6.

5 - 8 - 3z = -6

3z = 3

z = 1.

Then the value of a needed for the linear combination is of:

The credit card holder paid an additional D. $559.56 over the 12 months versus paying the balance in full before the end of the first month.

The additional payment made by the credit card holder results from paying installments instead of clearing the balance in the first month.

Installment plans attract finance charges at an annual percentage rate (APR), which increases the total amount paid.

Therefore, the additional payment is the difference between the total installment payments and the credit card balance at the beginning of the first month.

N (# of periods) = 12 months

I/Y (Interest per year) = 11.99%

PV (Present Value) = $6,299.59

PMT (Periodic Payment) = $-350

Results:

FV = $3,009.15

Sum of all periodic payments = $3,850 ($350 x 11)

Total Interest = $559.57

The total amount paid over the 12 months = $6,859.15 ($3,009.15 + $3,850)

The total amount paid in full in the first month = $6,299.59

Additional payment made via installments = $559.56 ($6,859.15 - $6,299.59)

Yes, it is possible for a line to be tangent to a circle at a point.

If a line is tangent to a circle at a point, it means that the line touches the circle at that point but does not intersect the circle at any other point. The line is perpendicular to the radius of the circle at the point of tangency.

In this case, the line QR is tangent to circle P at point Q. This means that the line QR touches the circle P at point Q, but does not intersect the circle P at any other point. The line QR is also perpendicular to the radius of circle P at point Q.

Answer:

Correct answer is ([7],[5])

Step-by-step explanation:

For the vertex form of the parabola, y = a(x – h)2 + k, the coordinates (h, k) of the vertex are:

(h, k) = (-b/2a, -D/4a)

where,

a is the coefficient of x2,

b is the coefficient of x,

D = b2 – 4ac is the discriminant of the standard form y = ax2 + bx + c.

We can conclude that there is a statistically significant correlation between the two variables, a and b. The correlation coefficient is .10, which indicates a weak positive relationship.

A correlation coefficient of .10 indicates that there is a weak positive relationship between the two variables, a and b. A p-value of .01 indicates that the correlation between the two variables is statistically significant, meaning that it is unlikely to be due to chance. This suggests that there is a real relationship between the two variables, even though it is weak.

To calculate the correlation coefficient, you can use the formula  where x and y are the two variables in question. In this case, the correlation coefficient is .10. This can be determined by plugging in the values for x and y and doing the necessary calculations.

Answer: The cost of a ticket for an adult is $12 while for children it is $10.

Step-by-step explanation:

Let's assume that cost for adults is A while for children it is C

Now,

2 adults and 4 children spend $64.

2A + 4C = 64

1 adult and 3 children spend $42.

A + 3C = 42

Multiply by 2

2A + 6C = 84

By subtracting equations

6C - 4C = 84 - 64

2C = 20

C = 10

A = 42 - 3(10)

A = 12

Hence "The cost of a ticket for an adult is $12 while for children it is $10".
