Answer:C

Step-by-step explanation:

The expression that most adequately expresses the model would be:

C). 3 × 2/5

A fraction is described as an expression employed to denote a segment or section belonging to a larger whole.

In the given question, it can be observed that the model contains 10 parts in total with a division of 5 each into 2 parts.

Since the division of 2 is made thrice, it gives 3 × 2/5 which makes the third option the correct one.

Thus, option C is the correct answer.

Answer:

the two possible amounts of change are £3.01 and 39p.

Step-by-step explanation:

Let's start by finding the possible prices for the pie after the 24% tip has been added. We know that the total price must be an exact number of pence, which means that the price before the tip must have been a multiple of 25 (since there are 100 pence in a pound).

The possible prices before the tip, between £1.30 and £2.99, are:

£1.30 = 130p

£1.31 = 131p

...

£2.98 = 298p

£2.99 = 299p

To find the prices after the 24% tip, we multiply each of these values by 1.24:

130p * 1.24 = 161.2p = £1.612 = £1.61 (rounded to 2 decimal places)

131p * 1.24 = 162.44p = £1.6244 = £1.62

...

298p * 1.24 = 369.52p = £3.6952 = £3.70

299p * 1.24 = 370.76p = £3.7076 = £3.71

So the possible prices for the pie after the 24% tip are between £1.61 and £3.71.

Next, we need to find the possible amounts of change that would result from paying with a £5 note and receiving the fewest possible coins. We can do this by subtracting the total cost of the pie from £5 and seeing which combinations of coins add up to that amount.

Let's start with the lowest possible price for the pie, £1.61. If we add 24% to that, the total cost is £1.99 (rounded to 2 decimal places), which means our change is £3.01. The fewest possible coins we could receive for that amount are:

£2 coin

£1 coin

1p coin

So the first possible combination of change is:

£2 + £1 + 1p = £3.01

Now let's try the highest possible price for the pie, £3.71. If we add 24% to that, the total cost is £4.61, which means our change is 39p. The fewest possible coins we could receive for that amount are:

20p coin

10p coin

5p coin

2p coin

2p coin

So the second possible combination of change is:

20p + 10p + 5p + 2p + 2p = 39p

Therefore, the two possible amounts of change are £3.01 and 39p.

The zeros of the function f(x) = 2x⁴ + 11x³ + 16x² + x - 6 are x = -3, x = -2,

x = -1 and x = 1/2 respectively

The zero of a real-, complex-, or generally vector-valued function f, is a member x of the domain of f such that f(x) vanishes at x; that is, the function f attains the value of 0 at x, or equivalently, x is the solution to the equation f(x) = 0. Graphically, the real zero of a function is where the graph of the function crosses the x‐axis; that is, the real zero of a function is the x‐intercept(s) of the graph of the function.

In the given problem, the zero of the function;

f(x) = 2x⁴ + 11x³ + 16x² + x - 6; -3 are

f(-3) = 2(-3)⁴ + 11(-3)³ + 16(-3)² -3 - 6 = 0

f(-2) = 2(-2)⁴ + 11(-2)³ + 16(-2)² - 2 - 6 = 0

f(-1) = 2(-1)⁴ + 11(-1)³ + 16(-1)² - 1 - 6 = 0

f(1/2) = 2(1/2)⁴ + 11(1/2)³ + 16(1/2)² - 1/2 - 6 = 0

The statements supported by the data in the table are:

The mean number of cars sold in a month is the same at both dealerships.

The total number of cars sold is the same at both dealerships.

The data for Admiral Autos shows greater variability.

To determine which statements are supported by the data in the table, let's analyze the given information:

The mean number of cars sold in a month is the same at both dealerships.

To calculate the mean, we need to find the average number of cars sold each month at each dealership.

For Admiral Autos:

(4 + 19 + 15 + 10 + 17) / 5 = 65 / 5 = 13

For Countywide Cars:

(9 + 17 + 14 + 10 + 15) / 5 = 65 / 5 = 13

Since both dealerships have an average of 13 cars sold per month, the statement is supported.

The median number of cars sold in a month is the same at both dealerships.

To find the median, we arrange the numbers in ascending order and select the middle value.

For Admiral Autos: 4, 10, 15, 17, 19

Median = 15

For Countywide Cars: 9, 10, 14, 15, 17

Median = 14

Since the medians are different (15 for Admiral Autos and 14 for Countywide Cars), the statement is not supported.

The total number of cars sold is the same at both dealerships.

To find the total number of cars sold, we sum up the values for each dealership.

For Admiral Autos: 4 + 19 + 15 + 10 + 17 = 65

For Countywide Cars: 9 + 17 + 14 + 10 + 15 = 65

Since both dealerships sold a total of 65 cars, the statement is supported.

The range of the number of cars sold is the same for both dealerships.

The range is determined by subtracting the lowest value from the highest value.

For Admiral Autos: 19 - 4 = 15

For Countywide Cars: 17 - 9 = 8

Since the ranges are different (15 for Admiral Autos and 8 for Countywide Cars), the statement is not supported.

The data for Admiral Autos shows greater variability.

To determine the variability, we can look at the range or consider the differences between each data point and the mean.

As we saw earlier, the range for Admiral Autos is 15, while for Countywide Cars, it is 8. Additionally, the data points for Admiral Autos are more spread out, with larger differences from the mean compared to Countywide Cars. Therefore, the statement is supported.

Based on the analysis, the statements supported by the data are:

The mean number of cars sold in a month is the same at both dealerships.

The total number of cars sold is the same at both dealerships.

The data for Admiral Autos shows greater variability.

Answer:

The small business made 48642 dollars last year.

Step-by-step explanation:

To solve this problem we can look at 73700 and see that it is 34 percent more than last year. To solve this problem we can multiply 73700 by 0.66.

The expression, in terms of x and y, for the Total number of sweets in 3 boxes and 2 packets is 3x + 2y.

To find the total number of sweets in 3 boxes and 2 packets, we need to add the number of sweets in the boxes and the number of sweets in the packets.

Let's start by finding the number of sweets in 3 boxes. Since there are x sweets in each box, the total number of sweets in 3 boxes would be 3x.

Next, let's determine the number of sweets in 2 packets. If there are y sweets in each packet, the total number of sweets in 2 packets would be 2y.

To find the total number of sweets in 3 boxes and 2 packets, we can add the two quantities we calculated:

Total number of sweets = 3x + 2y

Answer:

2 / 5

Step-by-step explanation:

Fractions are written in the form part/whole, in this case, the part is 18 and the whole is 45 so the fraction would be 18 / 45 which simplifies to 2 / 5.

For finding a 95% confidence interval:

a) The sample mean is x = 16.13.

The sample standard deviation is s = 6.948.

The degrees of freedom are df = 10.

The critical value of t for a 95% confidence interval is t = 2.228.

The margin of error is ME = t × s/√n = 2.228(6.948)/√11 = 4.263.

The 95% confidence interval is x ± ME = 16.13 ± 4.263 = (11.867, 20.393).

b) The 95% confidence interval is (11.867, 20.393).

This means that we are 95% confident that the true population mean number of visits per physical therapy patient is between 11.867 and 20.393 visits.

c) This is because the confidence interval is a range of values that is likely to contain the true population mean. If many samples of the same size are taken from the same population, then about 95% of the confidence intervals from these samples will contain the true population mean.
