Completed question;

Todd placed 32 square tiles along the edge of his wooden dining room table, as shown below.

Todd wants to paint a design on the wood along the diagonal shown. If each tile is 13 centimeters on each side, what is the length of the diagonal shown?

A. 182 centimeters

B. 169 centimeters

C. 130 centimeters

D. 91 centimeters

Step-by-step explanation:

To determine the length of diagonal, we have to first find the length of each side;

According to the attached image;

The length consist of 8 tiles

And breadth consist of 6 tiles

Length per tile = 13 centimeters

Length = 8 × 13 = 104 centimeters

Breadth = 6×13 = 78 centimeters

Using Pythagoras theorem;

diagonal length d = √(104^2 + 78^2)

d = 130 centimeters

Paula can pick 45 quarts of strawberries in 4.5 hours.

To find out how many quarts of strawberries Paula can pick in 4.5 hours, we need to convert the time into minutes for easier calculation. There are 60 minutes in 1 hour, so 4.5 hours equals 4.5 x 60 = 270 minutes.

Given that Paula can pick 5 quarts of strawberries in 30 minutes, we can set up a ratio to find the number of quarts she can pick in 270 minutes. The ratio is 5 quarts / 30 minutes = x quarts / 270 minutes.

Cross multiplying, we get 30x = 5 * 270. Solving for x, we find x = 5 * 270 / 30 = 45 quarts.

Paula can pick 45 quarts of strawberries in 4.5 hours at her current picking rate.

First, we need to understand the time frames we're working with. Paula picks 5 quarts of strawberries in a half an hour, and we want to know how much she can pick in 4.5 hours.

We are given that Paula can pick strawberries for a total of 4.5 hours. Now, we know that each hour has 60 minutes, so to get the total picking time in minutes, we multiply 4.5 (hours) by 60 (minutes per hour). This gives us a total of 270 minutes.

Next, we also know that Paula picks 5 quarts of strawberries in 30 minutes. If we want to find out how many 30-minute intervals are in 270 minutes, we simply divide 270 by 30. This gives us 9 intervals.

Finally, knowing that Paula can pick 5 quarts in each half-hour, we multiply this rate by the number of half-hour intervals. Therefore, 5 (quarts per half-hour) multiplied by 9 (half-hour intervals) equals 45 quarts.

So, Paula can pick 45 quarts of strawberries in 4.5 hours.

Answer:

Mean = 0.04

Step-by-step explanation: given that P = 4%

n = 300

the mean of the sampling distribution of the proportion of clients in this group who may not make timely payments will be

4/ 100 = 0.04

The mean of the sampling distribution is 12 loans.

Mean = 0.04

P = 4%

Loans = n = 300

To find the mean of the sampling distribution of the proportion of clients who may not make timely payments, we need to multiply the proportion of such clients by the total number of loans approved. In this case, the bank believes that 4% of the people who receive loans will not make payments on time. So, the mean is 4% of 300 loans.

Mean = (4/100) * 300

= 4 x 300/100

= 4 x 3

The following table shows the probability distribution for his score on one particular hole, known as the Water Hole.

Score 3 4 5 6 7

Probability 0.15 0.40 0.25 0.15 0.05.

We have to determine,

The probability that Miguel’s score on the Water Hole is at most 5.

According to the question,

Let the random variable X represent Miguel’s score on the Water Hole. In golf, lower scores are better.

Suppose one of Miguel’s scores from the Water Hole is selected at random.

Then,

The probability that Miguel’s score on the Water Hole is at most 5 is,

At most 5 means scores which are equal or less than 5.

P(at most 5) = P(X ≤ 5) = P(X = 3) + P(X = 4) + P(X = 5)

P(X ≤ 5) = 0.15 + 0.40 + 0.25

P(X ≤ 5) = 0.80

P(X ≤ 5) = 80%

Therefore,

There is 80% chance that Miguel’s score on the Water Hole is at most 5.

Hence, The probability that Miguel’s score on the Water Hole is at most 5 is 80%.

The chef can fill 32 cups with smoothies by converting all liquids into cups, resulting in 20 cups from pineapple juice, 8 cups from milk, and adding the 4 cups of apple juice.

To calculate how many cups can be filled with smoothies, we first need to convert all quantities of liquids into the same unit of measurement, which is cups in this case.

We have 5 quarts of pineapple juice, 4 pints of milk, and 4 cups of apple juice.

First, we convert quarts to cups. The conversion is:

1 quart = 4 cups

Therefore, 5 quarts of pineapple juice equals:

5 quarts  imes 4 cups/quart = 20 cups

Next, we convert pints to cups. The conversion is:

1 pint = 2 cups

Therefore, 4 pints of milk equals:

4 pints x 2 cups/pint = 8 cups

Adding the apple juice to the mix:

20 cups (pineapple juice) + 8 cups (milk) + 4 cups (apple juice) = 32 cups of smoothie

P(X=2)=0.04129

Step-by-step explanation:

-This is a binomial probability problem whose function is expressed as;

[tex]P(X=x)={n\choose x}p^x(1-p){n-x}[/tex]

-Given that p=0.6, n=8 , the probability that among the students in the sample exactly two are female is calculated as:

[tex]P(X=x)={n\choose x}p^x(1-p)^{n-x}\\\\P(X=2)={8\choose2}0.6^2(1-0.6)^6\\\\=0.04129[/tex]

Hence, the probability of exactly two females is 0.04129

To find the probability that exactly two students are female in a sample of 8 students, we can use the binomial probability formula. The probability is approximately 43.008%.

To find the probability that exactly two students are female, we can use the binomial probability formula. The formula is:

P(X = k) = C(n, k) * pk * (1-p)n-k

where:

In this case, n = 8, k = 2, and p = 0.6 (since 60% of the students are female). Plugging these values into the formula:

P(X = 2) = C(8, 2) * 0.62 * (1-0.6)8-2

Simplifying:

P(X = 2) = 28 * 0.62 * 0.46

P(X = 2) = 28 * 0.36 * 0.4096

P(X = 2) = 0.43008

Therefore, the probability that exactly two students are female in the sample is approximately 0.43008 or 43.008%.

Answer:  x = 4

Step-by-step explanation: The mean is the average of the given numbers, so take the numbers add them up and divide by the quantity of numbers. To get the answer to this question, you know the mean is 10 and you have two numbers. You take the 10, multiply it by 2 and you get how much the numbers add up to. You can combine x and 4x to get 5x. 5x=20. Divide 20 by 5 and you get the answer of x=4  

Answer:

x = 4

Step-by-step explanation:

To find the mean of two numbers, you have to add the numbers, then divide by 2.

So, if 10 is equal to the mean of x and 4x, it is equal to the sum of 4x and x divided by 2. If we put this in the form of an equation, we get:

[tex]\frac{x + 4x}{2} =10[/tex]

Now we can multiply both sides by 2, and get:

Step-by-step explanation:

In 'n' 10!  ways, books can be arranged. But, there are also 5! permutation of blue books 'n1', 2! permutation of identical green books 'n2', and 3! permutation identical black books 'n3'.

Therefore, for non identical arrangements:

[tex]\frac{n!}{n1!n2!n3!}[/tex]

[tex]\frac{10!}{5!2!3!}[/tex] = 2520

Therefore, the books can be arranged on a shelf in 2520 patterns

There are 3,024 different patterns in which the books can be arranged on the shelf.

To calculate the number of different patterns the books can be arranged on a shelf, we can use the concept of permutations. We have 5 identical blue books, 2 identical green books, and 3 identical black books, so the total number of books is 5 + 2 + 3 = 10.

The number of different patterns is given by the formula:

n! / (n1! * n2! * n3! * ...)

where n is the total number of books and n1, n2, n3, ... are the numbers of books of each type. Substituting the values, we get:

10! / (5! * 2! * 3!) = 3,024 patterns.

Answer:

a. $4.48¢

b. 9,967 people

ci. Multiplier: F = 25 × (1.09)^t

cii. Percent increase = 9.15%

Step-by-step explanation:

a. The equation we are going to use to calculate the future cost of bread in 5 years:

P = F/(1+r)^t

Where P is current cost, F = future cost(what we are required to calculate), r = percentage increase per year, t = time (years).

Where P = 2.75

r = 5/100 or 0.05

t = 10

F = ?

Substituting appropriately, we have:

2.75/1 = F/(1+0.05)^10

We then cross multiply

F = 2.75 × (1+0.05)^10

F = 2.75 × (1.05)^10

F = 2.75 × 1.62889

F = $4.48¢

Therefore, the bread will cost $4.48 in 10 years.

b. Here population is 42,000 people now. There's predicted 25% decrease in population every year for the next 5years. We are to calculate the expected population in 5 years. The equation that can be used to calculate the expected population:

P = F/(1 - r)^t

F = future population

P = present population

r = percentage of decrement

t = period.

Here P = 42,000

r = 25/100 = 0.25

t = 5

F = ?

Substituting accordingly:

42000 = F/(1 - 0.25)^5

Cross multiply

F = 42000 × [(1 - 0.25)^5]

F = 42000 × 0.2373

F = 9,967

The population in the next 5 years will decrease to 9,967 people.

c. Share of orange stock = $25 in the year 2000

The same share = $60 in 2010, we are required to determine the multiplier and percent increase.

Since the future value = $60, the present value = $25, the time = 2010 - 2000 = 10 years. Then we can use the formula:-

F = P × (1 + r)^t

60 = 25 × (1 + r)^10

(1 + r)^10 = 60/25

(1 + r)^10 = 2.4

1 + r = 10√2.4

1 + r = 1.0915

r = 1.0915 - 1

r = 0.0915

r = 9.15%

Therefore the multiplier is:

F = 25 × (1.09)^t

The percent increase = 9.15%

a. The cost of bread in 10 years will be approximately $4.48. b. Flood River City's population will drop to around 9,965 in 5 years. c. The Orange stock had a 2.4 multiplier, corresponding to a 140% increase over 10 years.

Let's address each part of the question with appropriate exponential equations:

a. Cost of a loaf of bread in 10 years:

We use the exponential growth formula:

Future Value = Present Value × (1 + growth rate)^number of years.

Here, the Present Value (P) is $2.75, the growth rate (r) is 5% or 0.05, and the number of years (n) is 10.

Future Value = 2.75 × (1 + 0.05)¹⁰

= 2.75 × (1.05)¹⁰

≈ 2.75 × 1.6289

≈ $4.48

So, in 10 years, the cost of the bread will be approximately $4.48.

b. Population of Flood River City in 5 years:

We use the exponential decay formula:

Future Value = Present Value × (1 - decay rate)^number of years.

Here, the Present Value (P) is 42,000, the decay rate (r) is 25% or 0.25, and the number of years (n) is 5.

Future Value = 42,000 × (1 - 0.25)⁵

= 42,000 × (0.75)⁵

≈ 42,000 × 0.2373

≈ 9,965

So, in 5 years, the population will be approximately 9,965.

c. Stock value multiplier and percent increase:

The stock value increased from $25 to $60 over 10 years. First, find the multiplier (M):

Multiplier (M) = Final Value / Initial Value

= 60 / 25 = 2.4

Next, calculate the percent increase:

Percent Increase = (Multiplier - 1) × 100

Percent Increase = (2.4 - 1) × 100 = 1.4 × 100 = 140%

So, the multiplier is 2.4 and the percent increase is 140%.

Answer:

P(E and F) = 0.123

P(E or F) = 0.677

P(E|F) = 0.189

Step-by-step explanation:

The formula for conditional probability is P(B|A) = P(A and B)/P(A)

The addition rule is P(A or B) = P(A) + P(B) - P(A and B)

∵ P(E) = 0.15

∵ P(F) = 0.65

∵ P(F|E) = 0.82

- Use the first rule above

∵ P(F|E) = P(E and F)/P(E)

- Substitute the values of P(F|E) and P(E) to find P(E and F)

∴ 0.82 = P(E and F)/0.15

- Multiply both sides by 0.15

∴ 0.123 = P(E and F)

- Switch the two sides

∴ P(E and F) = 0.123

Use the second rule to find P(E or F)

∵ P(E or F) = P(E) + P(F) - P(E and F)

∴ P(E or F) = 0.15 + 0.65 - 0.123

∴ P(E or F) = 0.677

Use the first rule to find P(E|F)

∵ P(E|F) = P(F and E)/P(F)

- P(F and E) is the same with P(E and F)

∴ P(E|F) = 0.123/0.65

∴ P(E|F) = 0.189

The painter charged $615 for a job that took 15 hours and required 3 cans of paint, which is answer choice (c).

Explanation:

To calculate the total charge for a painting job that took 15 hours and used 3 cans of paint, we need to plug these values into the painter's pricing formula, 35h + 30c.

Substituting the given values into the equation, we get:

Total charge = 35(15) + 30(3)

Total charge = 525 + 90

Total charge = $615

Therefore, the painter charged $615 for the job, which corresponds to answer choice (c).

Answer:

Step-by-step explanation:

Since there are 360° in a circle, and 240° is 2/3 of 360°, we can say that the area of the bolded sector is 2/3 the area of the whole circle. The area of a circle with a radius of r is πr², or approximately 3.14r², so the area of the whole circle is ≈ 3.14(16)² = 3.14(256) = 803.84 ft². Taking 2/3 of this gets us 803.84 * (2/3) ≈ 535.9 ft²

Answer:

Step-by-step explanation:

Each successive year, he

earned a 5% raise. It means that the salary is increasing in geometric progression. The formula for determining the nth term of a geometric progression is expressed as

Tn = ar^(n - 1)

Where

a represents the first term of the sequence(amount earned in the first year).

r represents the common ratio.

n represents the number of terms(years).

From the information given,

a = $32,000

r = 1 + 5/100 = 1.05

n = 20 years

The amount earned in his 20th year, T20 is

T20 = 32000 × 1.05^(20 - 1)

T20 = 32000 × 1.05^(19)

T20 = $80862.4

To determine the his total

earnings over the 20-year period, we would apply the formula for determining the sum of n terms, Sn of a geometric sequence which is expressed as

Sn = (ar^n - 1)/(r - 1)

Therefore, the sum of the first 20 terms, S20 is

S20 = (32000 × 1.05^(20) - 1)/1.05 - 1

S20 = (32000 × 1.653)/0.05

S20 = $1057920

The math teacher's salary in the 20th year, with a 5% annual raise, is approximately $85,200. Over the 20-year period, the total earnings amount to about $1,068,753.

The calculation also includes finding the total earnings over the 20-year period.

The salary in the 20th year can be calculated using the formula for compound interest: A = P(1 + r)^n, where A is the amount (salary in this case), P is the principal amount (initial salary), r is the rate of increase (5% expressed as 0.05), and n is the number of years.

Using the formula: A = 32000(1 + 0.05)^19, since the first year salary is given and we calculate the increase starting from the second year,

the salary in the 20th year is approximately $85,200.

To calculate the total earnings over 20 years, we sum all annual salaries over the 20 years which involve a geometric series. The sum of a geometric series can be found using the formula S = P(1 - (1+r)^n) / (1 - (1+r)), where S is the total sum, P is the initial amount, r is the rate, and n is the number of terms.

So, total earnings over 20 years is approximately $1,068,753.

To find tangent plane at the point (5,-1,1).

We know equation of tangent plane at the point $(x_0,y_0,z_0)[/tex] is,

[tex]z=f(x_0,y_0)+f_x(x_0,y_0)(x-x_0)+f_y(x_0,y_0)(y-y_0)\hfill (1)[/tex]

So that,

[tex]f(x_0,y_0)=6-\frac{6}{5}(5+1)=-\frac{6}{5}[/tex]

[tex]f_x=-\frac{6}{5}y\implies f_x(5,-1,1)=\frac{6}{5}[/tex]

[tex]f_y=-\frac{6}{5}x\implies f_y(5,-1,1)=-6[/tex]

Substitute all these values in (1) we get,

[tex]z=\frac{6}{5}(x-5)-6(y+1)-\frac{6}{5}[/tex]

[tex]\therefore z=\frac{6}{5}(x-5y-11)[/tex]

Which is the required euation of tangent plane.

Therefore the average sum of three numbers is 45:3=15. The number 15 is called the magic number of the 3x3 square. You can also achieve 15, if you add the middle number 5 three times. The odd numbers 1,3,7, and 9 occur twice in the reductions, the even numbers 2,4,6,8 three times and the number 5 once.

9+1+3+2= 15

Hope this helps you:)
