. The cost of 2 pizzas and 1 burger is ₹ 450. Write a linear equation for this situation and draw its graph.​

Answer:

The result to your inquiry is 2 7/24.

Step-by-step explanation:

Data:

Hank's cows yield = 4 3/4 and 4 1/8

Debra's cows yield = 5 1/2 and 5 2/3

Process:

1.- Convert the mixed numbers into improper fractions:

For Hank: (16 + 3)/4 = 19/4 and (32 + 1)/8 = 33/8.

For Debra: (10 + 1)/2 = 11/2 and (15 + 2)/3 = 17/3.

2.- Add Hank's and Debra's milk quantities:

Hank: 19/4 + 33/8 = 38/8 + 33/8 = 71/8.

Debra: 11/2 + 17/3 = 33/6 + 34/6 = 67/6.

3.- Subtract Hank's total from Debra's total:

67/6 - 71/8 = (268 - 213)/24.

Thus, it simplifies to 55/24.

- Convert back to a mixed number:

2

24 55

7

Where 55/24 equals 2 7/24.

4.- Conclusion:

Debra produced 2 7/24 more milk than Hank.

Answer: (97.98, 112.020)

Step-by-step explanation: We will create a 95% confidence interval for the average weight of melons.

Given the information, we determine that the critical value for the interval needs to be retrieved from a t distribution table due to the sample size being below 30 (specifically, 20), and we are provided with the sample standard deviation (s = 15 lb).

The parameters provided are:

Sample mean = x = 105 lb

Sample standard deviation = s = 15 lb

Sample size = n = 20

To establish the 95% confidence interval, we indicate that the level of significance is 5%.

The formula for the confidence interval is:

u = x + tα/2 × s/√n... for the upper limit

u = x - tα/2 × s/√n... for the lower limit.

tα/2 represents the critical value for the test (which will be determined using the t distribution table).

To derive tα/2, we look for the value based on the degrees of freedom (sample size - 1) against the significance level for a two-tailed test (α/2 = 0.025%) in a t distribution table.

For the upper limit, we calculate:

u = 105 + 2.093×15/√20

u = 105 + 2.093× (3.3541)

u = 105 + 7.020

u = 112.020.

u = 105 - 2.093×15/√20

u = 105 - 2.093× (3.3541)

u = 105 - 7.020

u = 97.98

Confidence interval (97.98, 112.020)

Detailed breakdown:

For beef, we calculate 12 * 8 (since 25 * 8 gives 200)

Thus, beef totals = 96

For chicken, we find 8 * 8 (again, because 25 * 8 equals 200)

Hence, chicken totals = 64

For pasta, the calculation is 5 * 8 (as 25 * 8 = 200)

Thus, pasta totals = 40

Conclusion- C] There are 32 extra students preferring beef over those who choose chicken

Answer:

Step-by-step explanation:

The graph can take on three forms as displayed in the figure.

(a) having no intersections

(b) having a single point of intersection (tangency)

(c) having two points of intersection.

Consequently, the maximum number of intersections that these graphs can yield is 2, as illustrated in figure (c).

Answer:

This phrasing is unusual, but let's attempt to tackle it:

M stands for Molly's weight

A represents Arthur's weight

G signifies Ginny's weight.

We can express the total weight as:

(M + A) + G

or alternatively as:

A + (G + M)

the first configuration illustrates Molly and Arthur's weights combined (hence their weight is presented as a single value), followed by Ginny's weight calculated separately.

The second configuration indicates Arthur's weight on its own, while Ginny and Molly's weights are combined (which is why their total weight appears as a single value)
