Answer:

Drinks = $1.5

Pizza = $10.50

Step-by-step explanation:

let d = drinks

p = pizza

p = 7d  equation 1

2p + 8d = 33 equation 2

from equation 1, we know the price of one pizza, the price of two pizzas can be determined by multiplying by 2

2p = 7d x 2 = 14d  eqn 3

Substitute for 2p in equation 2  

14d + 8d = 33

22d = 33

Divide both sides of the equation by 22

d = $1.5

Substitute for d in equation 1

p = 1.5 x 7 = $10.5

Answer: 480 milligrams

Step-by-step explanation:

We can solve this by using direct proportion whereby y = kx

where,

x = patient's weight = 92 pounds

k = constant

y = milligrams of antibiotics = 320

Using y = kx

320 = 92k

k = 320/92

k = 3.4782609

The antibiotic that should be given to a patient who weighs 138 pounds will be:

y = kx

y = 3.4782609 × 138

y = 480 milligrams

The antibiotic that should be given to a patient who weighs 138 pounds is 480 milligrams.

Anwser: B - 480 milligrams

Stochastic Gradient Descent is that it does the calculations faster than gradient descent and batch gradient descent that is where stochastic gradient descent preferred over deterministic gradient descent.

One of the most widely used techniques for selecting the model that best fits the training data is gradient descent. Typically, that model is the one that minimizes the loss function, such as in a linear regression by minimizing the Residual Sum of Squares. Stochastic Gradient Descent is a variation on gradient descent that is stochastic, or probabilistic. It performs significantly better in large datasets and fixes Gradient Descent's flaws. It is therefore frequently employed as the optimization algorithm in extensive, online machine learning techniques like Deep Learning. SGD is a method of generalization outside of the training set and is an extension of the gradient descent algorithm.

The answer is (a) There is not enough information to compare John's and Peter's exam scores.

A z score and a T score are both measures of how a particular score compares to the mean in a distribution, but they are calculated using different formulas. A z score measures the number of standard deviations a score is from the mean, while a T score is a linear transformation of the raw score that is adjusted to have a mean of 50 and a standard deviation of 10.

Without additional information about the specific distribution of scores, the mean, and the standard deviation, we cannot determine the raw scores of John and Peter or compare their relative performance on the exam. The z score of 0.5 for John indicates that his score is half a standard deviation above the mean, but we don't know the actual raw score. Similarly, the T score of 60 for Peter indicates that his score is above the mean, but we don't have enough information to determine the raw score or make a direct comparison between the two.

Statistic: average time 20 players, 6.32.

(D) The statistic is the average time it takes 20 professional football players to run a mile, which is 6.32 minutes in this case. The statistic was calculated by taking a sample of 20 professional football players and recording the amount of time it took each player to run a mile.

The recorded times were then summed and divided by the total number of players in the sample, which is 20. The resulting value is the average time it takes 20 professional football players to run a mile, also known as the statistic. In this case, the calculated statistic is 6.32 minutes.

It is important to note that the statistic only represents the sample of 20 players and not the entire population of professional football players. Therefore, the estimated average time it takes for all professional football players to run a mile may be different than the calculated statistic.

Answer:

\(y=5x+15\)

Step-by-step explanation:

Since this situation is a linear relationship between the number of movies and the total cost, we need to determine the slope of the line given our two ordered pairs \((x_1,y_1)\rightarrow(5,40)\) and \((x_2,y_2)\rightarrow(12,75)\):

\(m=\frac{y_2-y_1}{x_2-x_1}\\ \\m=\frac{75-40}{12-5}\\ \\m=\frac{35}{7}\\ \\m=5\)

Thus, our equation so far is \(y=5x+b\). Next, we need to find our y-intercept, \(b\), which represents our flat fee. We do so by using one of our original given ordered pairs:

\(y=5x+b\\\\40=5(5)+b\\\\40=25+b\\\\15=b\)

Therefore, our final equation for the function is \(y=5x+15\)

Total stockholders’ equity 7,800,000

Statement of stockholders’ equity for CC for the year ended December 31, 2012:Particulars Amount ($)
Common Stock 100,000

Additional Paid-in Capital 4,100,000
Retained Earnings (Opening Balance) 3,000,000
Add: Net Income for the year ended December 31, 2012 800,000
Total retained earnings 3,800,000

Less: Cash Dividend Declared on July 1 and paid on July 31 (200,000)
Retained earnings (Closing balance) 3,600,000
Total stockholders’ equity 7,800,000

Explanation:The given information is as follows:Common Stock on January 1, 2012 = $100,000Additional Paid-in Capital on January 1, 2012 = $4,100,000

Retained Earnings on January 1, 2012 = $3,000,000Net Income for the year ended December 31, 2012 = $800,000Cash Dividend Declared on July 1 and paid on July 31 = $200,000

To prepare the statement of stockholders’ equity for the year ended December 31, 2012, we will begin by preparing the opening balances of each of the equity accounts. We will then add the net income to the retained earnings account.

The closing balance for retained earnings is then computed by subtracting the cash dividend declared and paid from the total retained earnings. Finally, the total stockholders' equity is calculated by adding the balances of all the equity accounts.

Calculations:Opening balance of common stock = $100,000

Opening balance of additional paid-in capital = $4,100,000

Opening balance of retained earnings = $3,000,000

Net Income for the year ended December 31, 2012 = $800,000

Retained earnings (Opening Balance) = $3,000,000

Add: Net Income for the year ended December 31, 2012 = $800,000

Total retained earnings = $3,800,000Less: Cash Dividend Declared on July 1 and paid on July 31 = $200,000Retained earnings (Closing balance) = $3,600,000

Total stockholders’ equity = Common Stock + Additional Paid-in Capital + Retained Earnings (Closing balance) = $100,000 + $4,100,000 + $3,600,000 = $7,800,000

Therefore, the statement of stockholders’ equity for CC for the year ended December 31, 2012, is as follows:Particulars Amount ($)
Common Stock 100,000
Additional Paid-in Capital 4,100,000

Retained Earnings (Opening Balance) 3,000,000
Add: Net Income for the year ended December 31, 2012 800,000
Total retained earnings 3,800,000

The rate of discount for the CD radio cassette is 17.65%.

To calculate the rate of discount, we need to find the difference between the original price and the discounted price, and then divide that difference by the original price.

Original price: $16,999

Discounted price: $13,999

So, the Discount amount

= Original price - Discounted price

= $16,999 - $13,999

= $3,000

Rate of discount = (Discount amount / Original price) * 100%

= ($3,000 / $16,999) x 100%

≈ 17.65%

Therefore, the rate of discount for the CD radio cassette is 17.65%.

A relation where each input has precisely one output was described as a function. Each input is mapped to a single output value, in other words. Every input value is translated into a single distinct output value in a one-to-one function. Another way to phrase it is that no two input items produce the same output value.

The function f(x)=x +2 is depicted in the graph above. This graph does not map the same x-value to the same y-value everywhere, indicating that it is a one-to-one function.

Here are some additional one-to-one functions:

Because no 2 input values have the same cube root and thus do not produce the same outputs, X³+1 is a one-to-one function.

Because different inputs might result in the same outputs, X² is not a function. Consider the numbers -1 and 1. These two values both produce the value 1, indicating that this equation is not one-to-one.
