Answer:

692 different meals are possible.

Step-by-step explanation:

- There are 3 courses, appetizers, main dishes and desserts.

- There are 6 choices of appetizers, 10 choices of main dishes and 8 choices of desserts.

- A customer can order only one dish from each course and can have a meal consisting of one course only, two different courses or a meal with all three courses.

To find the number of different meals possible, we take the choice of number of courses one by one.

- If a customer decides to take a meal with only one course.

The customer can take only 1 choice out of 6 choices of appetizers or 1 choice out of 10 choices of main dishes or 1 choice out of 8 choices of desserts.

6C1 + 10C1 + 8C1 = 6 + 10 + 8

= 24 different meals

- If a customer decides on a two course meal

The customer can combine a choice of appetizer with a choice of main dish or a choice of appetizer with desert or a choice of main dish with dessert with order unimportant.

(6C1 × 10C1) + (6C1 × 8C1) + (10C1 × 8C1)

= (6 × 10) + (6 × 8) + (10 × 8)

= 60 + 48 + 80

= 188 different meals

- If a customer decides to take a combination of all the 3 courses.

This means a combination of a choice from each of the courses for the 3 courses.

6C1 × 8C1 × 10C1

= 6 × 8 × 10

= 480 different meals.

Total number of different meals possible

= 24 + 188 + 480

= 692 different meals.

Answer: Option D.

Step-by-step explanation:

this is a quadratic equation of the form:

y = ax^2 + bx + c

First, things you must see.

The graph opens up, so we must have thata a is greater than zero, so we can discard the first option.

Second, we can see that the vertex is located in x ≈ 70

The vertex of a quadratic equation is: x = -b/2a

so we have:

70 = -b/2a

let's try our options and see if we can discard other:

B:

-b/2a = 69.9/2 = 34.95

we can discard this option.

C:

-b/2a = 78/2 = 39 we can discard this option.

D:

-b/2a = 69.9/2*0.5 = 69.9

This is the only one that fits, so this is the correct option.

Answer:

Its D!!

Answer: People will pay about $5 for a ticket if 50 are sold.

Step-by-step explanation:

What we can deduce from this graph is the more expensive the tickets are, the less tickets are sold.

So far, the greatest number of tickets sold are 40 with a price of around $10.

Now, if people were to sell 50 tickets, following with the graph, it

would mean that the price would have to be less than 10.

Only one of the options is less than 10, and that is 5, so therefore, the answer is 5.

Answer:

The price of tomato per pound is $1.36

Step-by-step explanation:

Jordan has $5.37.

He is buying one red pepper for $1.29

He is also buying three pounds of tomatoes.

If he has exactly the right amount of money he needs, then

5.37 = 1.29 + 3x

Where x is the price of tomato per pound

And( 5.37 = 1.29 + 3x) is the equation to solve for x

5.37 = 1.29 + 3x

5.37-1.29 = 3x

4.08 = 3x

4.08/3 = x

1.36 = x

The price of tomato per pound is $1.36

To verify it again..

3*1.36 + 1.29

= 4.08 +1.29

= 5.37 ( which is the initial total amount)

Answer:

Jordan has $5.37, which he is using to buy ingredients to make salsa. He is buying one red pepper for $1.29 and three pounds of tomatoes. If Jordan has exactly the right amount of money he needs, what is the price per pound of the tomatoes?

Choose the correct equation to represent this real-world problem.

✔ 5.37 = 3x + 1.29

Solve the equation and verify the reasonableness of your answer.

A pound of tomatoes costs

✔ $1.36

Answer:

14.46% probability that the instructor can finish grading in 4 and a half hours

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal probability distribution

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For sums of n values from a distribution, the mean is [tex]n\mu[/tex] and the standard deviation is [tex]s = \sqrt{n}\sigma[/tex]

In this problem, we have that:

[tex]\mu = 6*50 = 300, s = \sqrt{50}*4 = 28.2843[/tex]

What is the probability that the instructor can finish grading in 4 and a half hours

Four and half hours is 4.5*60 = 270.

So this probability is the pvalue of Z when X = 270.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{270 - 300}{28.2843}[/tex]

[tex]Z = -1.06[/tex]

[tex]Z = -1.06[/tex] has a pvalue of 0.1446

14.46% probability that the instructor can finish grading in 4 and a half hours

Step-by-step explanation:

The model for the amount of carbon-14 after t years is given by:

[tex]A(t) = A(0)e^{-0.000121t}[/tex]

In which A(0) is the original amount.

The paint contained 3% of the original carbon-14.

This means that [tex]A(t) = 0.03A(0)[/tex]. This means that we have to find t.

[tex]A(t) = A(0)e^{-0.000121t}[/tex]

[tex]0.03A(0) = A(0)e^{-0.000121t}[/tex]

[tex]e^{-0.000121t} = 0.03[/tex]

[tex]\ln{e^{-0.000121t}} = \ln{0.03}[/tex]

[tex]-0.000121t = \ln{0.03}[/tex]

[tex]t = -\frac{\ln{0.03}}{0.000121}[/tex]

[tex]t = 28980[/tex]

The painting area is approximately 28980 years old.

Answer:

If Hank shoots from inside the three-point line we can say that he has to shoot 246 inches to make the ball into the hoop.

Hank's distance from the center of the basket, if he is shooting from inside the three-point line, would be less than the distance of the three-point line from the basket. This distance varies between 6.75 metres (NBA, FIBA) or 6.1 metres (college games).

When a player stands inside the three-point line in basketball, it can be said that they are less than 6.75 metres (for NBA and FIBA) or 6.1 metres (for college games) from the centre of the basket. This distance varies because different basketball associations have different guidelines for the distance of the three-point line from the center of the basket. For instance, the NBA has its line located 7.24 metres from the basket, FIBA has it at 6.75 metres, and in college games, it's 6.1 metres away. As such, if Hank is shooting inside the three-point line, he is definitely standing closer than these distances to the basket's center.

Answer:

3.5, three-and-a-half, 7/2

Answer:

0.078 or 7.8%

Step-by-step explanation:

Mean salary (μ) = $37,764

Standard deviation (σ) = $5,100

The z-score for any given teacher's salary in California, X, is determined by:

[tex]z=\frac{X-\mu}{\sigma}[/tex]

For X = $45,000:

[tex]z=\frac{45,000-37,764}{5,100}\\ z=1.419[/tex]

A z-score of 1.419 corresponds to the 92.20th percentile of a normal distribution. Therefore, the probability that a salary is greater than $45,000 is:

[tex]P(X>\$45,000) = 1-0.9220\\P(X>\$45,000) = 0.078=7.8\%[/tex]

The probability is 0.078 or 7.8%.

To find the probability of a teacher's salary being more than $45,000 in California, calculate the Z-score using the formula given and find the corresponding probability. This calculation reveals there's a 7.78% chance of a randomly selected teacher's salary exceeding $45,000.

To find the probability that a randomly selected teacher’s salary in California is greater than $45,000 when the salaries are normally distributed with a mean of $37,764 and a standard deviation of $5,100, we use the Z-score formula: Z = (X - μ) / σ, where X is the value in question, μ is the mean, and σ is the standard deviation. In this case, X = $45,000, μ = $37,764, and σ = $5,100.

Calculating the Z-score gives us: Z = ($45,000 - $37,764) / $5,100 ≈ 1.42. Using the Z-table or a calculator with normal distribution functions, we find that the area to the right of Z = 1.42 corresponds to the probability we are looking for.

This area represents the probability that a teacher’s salary is greater than $45,000. Since we know the total area under the normal curve equals 1 (or 100%), the area to the right of Z = 1.42 is approximately 0.0778, which means there is a 7.78% chance that a randomly selected teacher’s salary in California is greater than $45,000.

Answer: 45

Explanation: Remember that dividing by a fraction is the same thing as multiplying by the reciprocal of that fraction or that fraction flipped.

Also, think of the 15 in this problem as 15/1.

So we can rewrite 15/1 ÷ 1/3 as 15/1 · 3/1.

Multiplying across the numerators and the denominators,

we find that our answer is 45/1 or just 45.

15 divided by 1/3 is equal to 45.

To divide 15 by 1/3, we can interpret it as finding how many groups of 1/3 can be made from 15.

To begin, we can convert the division of 15 by 1/3 into a multiplication problem by taking the reciprocal of 1/3, which is 3/1 or simply 3.

So, we have:

15 ÷ (1/3) = 15 x 3

Multiplying 15 by 3, we get:

15 x 3 = 45

Therefore, 15 divided by 1/3 is equal to 45.

In other words, 15 can be divided into 45 equal parts of size 1/3. Each of these parts represents the quotient when dividing 15 by 1/3.

When we multiply 1/3 by 45, we get 15. This confirms that 15 divided by 1/3 is indeed equal to 45.

(C) and (d) => check explanation.

Step-by-step explanation:

To Calculate for Σx we will have to add all the values for x that is the summation of x-values.

Σx = 11 + 0 + 36 + 22 + 34 + 24 + 25 + -11 + -11 + -22 = 108.

Σx^2 = 11 × 11 + 0 × 0 + 36 × 36 + 22 × 22 + 34 × 34 + 24 ×24 + 25 × 25 + -11 × -11 + -11 × -11 + -22 × -22 = 4984.

(b). Sample mean for x = 108/10 = 10.8.

Variance for x:

11 - 10.8 = 0.3

0 - 10.8 = -10.8

36 - 10.8 =25.2.

22 - 10.8=11.2.

34 - 10.8 = 23.2

24 -10.8 = 13.2.

25 - 10.8= 14.2

-11 - 10.8 = -21.8.

-11 - 10.8 = - 21.8

-22 -10.8 = -32.8.

Total=0.1

Standard deviation for x = √ s^2 = 0.3162

This can be done for y too

The sample means for annual returns of the Vanguard Total Stock Index (x) and Vanguard Balanced Index (y) have been computed as 10.8 and 8.5 respectively. The inclusion of bonds in a portfolio can lower overall return slightly while also reducing the risk.

The student's task revolves around the subject of statistical analysis, here applied to investment portfolio management. Their goal is to compute the sample mean (average) for two variables - x and y - which each represent annual returns for certain types of portfolios.

Portfolio x represents a 100% stock holding in the Vanguard Total Stock Index, while y represents a 60% stock and 40% bond holding in the Vanguard Balanced Index. Such portfolios carry varying degrees of risk, with all-stock portfolios generally accepted to be more volatile, yet offering higher potential returns than mixed portfolios.

In order to calculate the sample means for x and y, you simply add together all the annual returns for each, then divide by the number of years.

For x: (11 + 0 + 36 + 22 + 34 + 24 + 25 - 11 - 11 - 22)/10 = 10.8 (rounded to the nearest tenth)

For y: (9 - 3 + 28 + 14 + 23 + 16 + 14 - 3 - 4 - 9)/10 = 8.5 (rounded to the nearest tenth)

As seen, stocks did yield a higher average return over the period in consideration, though the range of returns was also much wider. By adding bonds to the portfolio (shown by y), the overall return reduced slightly, but so did the risk (variability) of returns.

Answer:

In my own words interest rate is the  proportion of a loan that is charged as interest to the borower, typically expressed as an annual percentage of the loan outstanding. :D Hope this help and do you like brownies

Step-by-step explanation:

Final answer:

The interest rate is the cost of borrowing money or the return on investment deposited in financial institutions. It's influenced by financial regulations like usury laws, which cap the maximum interest rate to prevent excessive charges.

Explanation:

The interest rate is often referred to as the "price" of borrowing money in the financial market, and it's also the rate of return on an investment. When you deposit money into a savings account at a bank, the bank will pay you interest, which is a percentage of your deposits. This is the interest rate. Conversely, when you take out a loan, you will pay interest to the lender, which is the cost of borrowing the funds you need to purchase something, like a car or a computer.

There are also regulations like usury laws that set maximum limits on the interest rates that can be charged, ensuring that lenders do not exceed legal thresholds. The concept is similar to the idea of minimum wage, which sets a 'price floor' for hourly wages, below which it is illegal for employers to pay employees.
