Answer:11.5

Step-by-step explanation:

distance=6 2/5 + 2 3/4 + 2 1/3

d=(5x6+2)/5 + (4x2+3)/4 + (3x2+1)/3

d=32/5 + 11/4 + 7/3

d=(12x32+15x11+20x7) ➗ 60

d=(384+165+140) ➗ 60

d=689 ➗ 60

d=11.5

The total distance  did she run is 11.5 miles.

It is required to find the total distance.

The distance of an object can be defined as the complete path travelled by an object .Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion.

Given:

Melissa ran 6 2/5 miles north ,2 3/4 west and 2 1/3 south.

According to given question we have,

Total distance=6 2/5 + 2 3/4 + 2 1/3

d=(5x6+2)/5 + (4x2+3)/4 + (3x2+1)/3

d=32/5 + 11/4 + 7/3

d=(12x32+15x11+20x7) /60

d=(384+165+140) / 60

d=689 / 60

d=11.5 miles.

Therefore, the total distance  did she run is 11.5 miles.

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]

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:

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.

The experimental probability  of the coin landing on tails is 1/3

Step-by-step explanation:

Total no. of times coin tossed = 18

No. of times lands on head = 12

No. of times lands on tail = 18-12

No. of times lands on tail = 6

We are supposed to find  the experimental probability  of the coin landing on tails

So,  the experimental probability  of the coin landing on tails =[tex]\frac{\text{favorable outcome}}{\text{Total outcome}}[/tex]

So,  the experimental probability  of the coin landing on tails =[tex]\frac{6}{18}[/tex]

So,  the experimental probability  of the coin landing on tails =[tex]\frac{1}{3}[/tex]

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.

Step-by-step explanation:

There is more than one way to solve this; the easiest way is to plug in some numbers for x. We can see the roots are (3,0) and (7,0) and the lowest point is (5,0). So when we plug in 3 or 7, we should get zero.

B: (3-3)(3-7)=0

D: 3(3-3)(3-7)=0

So we have two possible solutions, So to check, let's find a point where we can easily find the y value.

When x is equal to 4,5, or 6, there is an integer value for y. so let's plugin 5:

(5-3)(5-7)=-4

We can see when x is five, y has to be -12, so that is not the answer, thus d is the final answer.

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: 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.

(a). Σx= 108, Σx^2 = 4984, Σy^2 = 2,157.

(b). 10.8, 0.1.

(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.

Σy^2 = 9× 9 + -3 × -3 + 28 ×28 + 14 × 14 + 23 × 23 + 16 × 16 + 14× 14 + -3 ×-3 + -4 × -4 + -9 × -9= 2,157.

(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

(c). 75% Chebyshev interval around the mean for x values = 10.8 + 2 (0.3162); 10.8 - 2(0.3162).

=> (11.4324, 10.1676).

(d). The coefficient of variation= (0.3162)/10.8 × 100 = 2.92%.

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.

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.

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.
