According to the given information, Jeremy is saving approximately $20.56 per week for his new tires.

What is basic arithmetic?

Basic arithmetic refers to the fundamental operations of arithmetic, which include addition, subtraction, multiplication, and division. These operations are used to perform calculations with numbers, such as counting, computing sums, finding differences, calculating products, and determining quotients.

We can use this information to find Jeremy's weekly savings rate.

To find the weekly savings rate, we need to first find out how much Jeremy saves in a week.

For the first month, which is four weeks, Jeremy saves $230.

For the next three months, which is 12 weeks, he saves an additional $329 - $230 = $99.

Therefore, in total, Jeremy saves $230 + $99 = $329 in 16 weeks.

His weekly savings rate is then:

$329 / 16 weeks = $20.56 per week (rounded to the nearest cent)

So, Jeremy is saving approximately $20.56 per week for his new tires.

Answer:

To find the five-number summary of a data set, we need to find the minimum value, the first quartile (Q1), the median, the third quartile (Q3), and the maximum value.

We can first put the data set in order from smallest to largest:

14, 17, 19, 23, 25, 28, 30, 34, 40, 43

The minimum value is 14, and the maximum value is 43.

To find the median, we need to find the middle value. Since there are 10 numbers in the data set, the median is the average of the fifth and sixth values:

Median = (25 + 28) / 2 = 26.5

To find the first and third quartiles, we can use the median as a reference point. The first quartile (Q1) is the median of the lower half of the data set, and the third quartile (Q3) is the median of the upper half of the data set.

The lower half of the data set consists of the first five values:

14, 17, 19, 23, 25

The median of these values is:

Q1 = (19 + 23) / 2 = 21

The upper half of the data set consists of the last five values:

28, 30, 34, 40, 43

The median of these values is:

Q3 = (34 + 40) / 2 = 37

Therefore, the five-number summary for this data set is:

Minimum = 14

Q1 = 21

Median = 26.5

Q3 = 37

Maximum = 43

Looking at the answer choices, we can see that option C is the correct answer:

OA. 14, 19, 29, 34, 43

B. 14, 23, 26.5, 30, 43

C. 14, 19, 26.5, 34, 43

The probability of rolling a sum of 7 when rolling a pair of six-sided number cubes is 1/6

It is a branch of mathematics that deals with the occurrence of a random event.

We need to count the number of ways in which the cubes will have a sum of 7

There are six possible ways to roll a sum of 7

(1, 6), (2, 5), (3, 4), (4, 3), (5, 2), and (6, 1).

Since each cube has six possible outcomes, there are a total of 6 x 6 = 36 possible outcomes when rolling two number cubes.

The probability of rolling a sum of 7 is the number of ways to roll a sum of 7 divided by the total number of possible outcomes:

Probability of rolling a sum of 7 = number of ways to roll a sum of 7 / total number of possible outcomes

Probability of rolling a sum of 7 = 6 / 36

Probability of rolling a sum of 7 = 1 / 6

Therefore, the probability of rolling a sum of 7 when rolling a pair of six-sided number cubes is 1/6

The total amount of fencing change by 236.66 feet.

The average rate of change is 2.3666.

It quantifies how much the function changed per unit on average over that time interval. The slope of the straight line connecting the interval's ends on the function's graph is used to calculate it.

First, When width is 200 ft then

length = 19000/ 200 = 95 feet

and, When width is 300 ft then

length = 19000/ 300 = 63.33 feet

1) The amount of Fencing

= 3 x width + 2 x length

= 3 x 200 + 2 x 95

= 600 + 190

= 790 feet

2) The amount of Fencing

= 3 x width + 2 x length

= 3 x 300 + 2 x 63.33

= 900 + 126.66

= 1026.66 feet

So, the Change is

= 236.66 feet

Thus, the avreage rate of change

The solution to the division problem 2x³-4x²-3x-9/ x-3 is 2x² + 6x + 15

Synthetic division is a method of polynomial division used to divide a polynomial by a linear expression of the form x - a, where a is a constant. It is a shorthand way of performing long division for polynomials and is particularly useful when the divisor is of the form x - a, as it eliminates the need for writing out the full divisor in each step of the division process.

The advantage of synthetic division is that it is quicker and easier than long division, especially for dividing polynomials by linear expressions. It can also be used to evaluate a polynomial at a specific value of x, by setting the divisor to x - a and using the result in the final row of the synthetic division as the value of the polynomial at x = a.

We can use long division to solve this problem:

        2x² + 6x + 15

   ---------------------

x - 3 | 2x³ - 4x² - 3x - 9

       - (2x³ - 6x²)

       ---------------

              2x² - 3x

              - (2x² - 6x)

              ------------

                     3x - 9

                     - (3x - 9)

                     --------

                            0

So the solution to the division problem is:

2x² + 6x + 15

Solving a system of equations we will see that x = 2.

We know that the two rectangles are similar, so if k is the scale factor between them, we can write:

3x - 1 = k*4

8x -1  = k*12

So we have a system of equations.

Taking the quotient between the two equations we will get:

(3x - 1)/(8x - 1) = k*4/k*12

(3x - 1)/(8x - 1) = 4/12

3x - 1 = (1/3)*(8x - 1)

Answer:

the bag contains $10.89.

Step-by-step explanation:

Let's start by using algebra to represent the number of coins in terms of one variable. Let x be the number of pennies in the bag. Then:

The number of nickels is 4 more than the number of pennies, so there are x + 4 nickels.

The number of dimes is 30% of the total, so there are 0.3 * 50 = 15 dimes.

The number of quarters is the remaining coins: 50 - (x + x + 4 + 15) = 31 - 2x.

To find the total amount of money, we need to multiply the number of each type of coin by its value and add them up. Using the values of the coins:

Pennies: x * $0.01

Nickels: (x + 4) * $0.05

Dimes: 15 * $0.10

Quarters: (31 - 2x) * $0.25

Adding these expressions and simplifying, we get:

Total = 0.01x + 0.05(x + 4) + 0.10(15) + 0.25(31 - 2x)

= 0.01x + 0.05x + 0.20 + 1.50 + 7.75 - 0.50x

= 0.06x + 9.45

Now we need to find x, the number of pennies. We know that 14% of the coins are pennies, so:

0.14 * 50 = 7 = x + (x + 4) + 15 + (31 - 2x)

Solving for x, we get:

7 = 50 - x - 19

x = 24

So there are 24 pennies, 28 nickels, 15 dimes, and 3 quarters in the bag. The total amount of money is:

Total = 0.06(24) + 9.45 = $10.89

Therefore, the bag contains $10.89.

No, it is not possible for Mario to have drawn this figure.

The circumference, which is the distance around the object, the diameter, which is the length of a circle measured from one end to the other and passing through its center, and the radius, which is equal to half of the diameter, are the three key characteristics.

If two tangents to a circle meet at a point outside the circle, they must be parallel to each other.

If the two points where the two tangents meet the circle separate the circle into two semicircles, then the center of the circle must lie on the line containing the two points.

However, since the tangents are parallel, they do not intersect the line containing the two points, and therefore, the center of the circle cannot lie on this line.

This contradicts the definition of a circle, which states that the center of a circle is equidistant from all points on the circle.

Therefore, Mario's reasoning is flawed, and it is not possible for him to have drawn this figure.

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion.

Therefore, using proportion,

BC / x = 12 / x - 4 = x + 7 / 5

12 / x - 4 = x + 7 / 5

cross multiply

12 × 5 = (x - 4)(x + 7)

60 = x² + 7x - 4x - 28

x² + 3x - 28 - 60 = 0

The probability that the sample proportion will be at most 2% more than the population proportion is approximately 0.7007.

The sample size is n = 197, and the population fraction of complaints resolved by the Better Business Bureau is 0.75. P(p 0.77), where p is the sample percentage, is the chance that the sample proportion is no more than 2% greater than the population proportion.

The distribution of the sample proportion can be approximated by the central limit theorem as having a mean of 0.75 and a standard deviation of sqrt[(0.75)(0.25)/197] = 0.038.

The sample proportion is then standardised as follows:

Z = (p - μ) / σ = (0.77 - 0.75) / 0.038 = 0.526

We are looking for P(Z 0.526). We can determine that P(Z 0.526) = 0.7007 by using a calculator or a conventional normal distribution table.

Hence, 0.7007 is around how likely it is that the sample proportion will be at most 2% higher than the population proportion.
