The value of sin 75 without using a calculator is 1/4(√2 +√6)

From the question, we have the following parameters that can be used in our computation:

sin(75)

This can be expanded as

sin(75) = sin(45 + 30)

Using the sine rule, we have

sin(75) = sin(45)sin(30) + cos(45)cos(30)

Evaluate the trigonometry ratios

So, we have

sin(75) = √2/2 * 1/2 + √2/2 * √3/2

So, we have

sin(75) = √2/4 + √6/4

Evaluate the sum

sin(75) = 1/4(√2 +√6)

Hence, the value is sin(75) = 1/4(√2 +√6)

The cost price of the article, which is sold for Rs. 150 at a gain but if sold for Rs. 135 would have resulted in a loss equal to 50% of the original gain, is Rs. 127.50.

The cost price is the difference between the selling price and the profit or gain.

The difference is determined by subtraction.

Selling price of the article = Rs. 150

Loss if sold at Rs. 135 = 50% of the original gain

Original gain = Rs. 15 (Rs. 150 - Rs. 135)

50% of the original gain = Rs. 7.50 (Rs. 15 x 50%)

Cost price of the article = Rs. 127.50 (Rs. 135 - Rs. 7.50)

Thus, the cost price is Rs. 127.50.

The virus will thus increase from 160 to 600 in around 10 days.

A virus is a submicroscopic infectious agent that only reproduces inside of an organism's live cells.

We can resolve this issue using a proportion. Let x be the period of time needed for the virus to multiply from 160 to 600. Then: (240 - 160) / 18 = (600 - 160) / x

This equation may be written as

80/18 = 440/x.

Cross-multiplying:

80x = 18 * 440

80 divided by both sides yields x = 9.9

We obtain x = 10 by rounding to the next full value.

Therefore, The virus will thus increase from 160 to 600 in around 10 days.

Step-by-step explanation:

There is only one way for the doctor to visit all seven patients exactly once.

A combination is a way of selecting items from a larger set, where the order of the items is not important. In this problem, we need to select seven patients out of a larger set of seven patients, so we can use the formula for the number of combinations of n items taken r at a time:

C(n,r) = n! / (r!(n-r)!)

where n is the total number of items, r is the number of items to be selected, and the exclamation mark represents the factorial function.

In this case, we need to find the number of combinations of 7 patients taken 7 at a time, which can be written as:

C(7,7) = 7! / (7!(7-7)!) = 7! / (7!0!) = 1

The order in which she visits the patients does not matter since each patient is visited only once.

To determine the minimum area of the piece of fabric Jonna needs, we need to calculate the diameter of the circle after adding 2 inches to the radius.

The radius of the pillow is half its diameter, which is 15/2 = 7.5 inches.

When Jonna adds 2 inches to the radius, the new radius becomes 7.5 + 2 = 9.5 inches.

The diameter of the circle with the new radius is 2 x 9.5 = 19 inches.

Therefore, Jonna needs to cut a circular piece of fabric with a diameter of 19 inches.

To calculate the minimum area of the fabric, we need to use the formula for the area of a circle:

Area = π x (radius)^2

The radius is 9.5 inches, so:

Area = π x (9.5)^2

Area = π x 90.25

Area ≈ 283.77 square inches

Therefore, Jonna needs a piece of fabric with a minimum area of approximately 283.77 square inches.

As per the given percentage, the value of the loan 10 years after it starts is £4506.32.

We know the values of P and A for the first two years. So, we can use these values to find the value of r. Let's use the formula for the first year:

2645 = 2500(1 + r/1)¹ˣ¹

Simplifying the equation, we get:

1 + r = 2645/2500

1 + r = 1.058

r = 0.058 or 5.8%

Therefore, the interest rate per annum is 5.8% (to 1 decimal place).

Now, let's move on to finding the value of the loan after 10 years. We can use the same formula for compound interest, but we need to substitute the values of P, r, n, and t accordingly. Here's the formula:

A = P(1 + r/n)ⁿˣ

Where:

P = 2500

r = 0.058

n = 1 (as the interest is compounded annually)

x = 10

Substituting these values, we get:

A = 2500(1 + 0.058/1)¹ˣ¹⁰

A = 2500(1.058)¹⁰

A = 4506.32

To factor the expression x^2 - 14 - 4x, we can use the technique of grouping.

First, we can rearrange the terms as:

x^2 - 4x - 14

Next, we can factor out a common factor of x from the first two terms:

x(x - 4) - 14

Then, we can factor out a negative 1 from the last two terms:

x(x - 4) - 1(14)

Finally, we can write the expression as the product of two binomials:

(x - 4)(x - 14)

Answer:

Step-by-step explanation:

To find the mean absolute deviation for a set of data, we first need to find the mean (average) of the data set. Then, for each data point, we find the absolute value of the difference between the data point and the mean. Finally, we take the mean of those absolute differences.

Step 1: Find the mean

Mean = (6+7+10+12+13+4+8+12)/8 = 72/8 = 9

Step 2: Find the absolute differences

|6-9| = 3

|7-9| = 2

|10-9| = 1

|12-9| = 3

|13-9| = 4

|4-9| = 5

|8-9| = 1

|12-9| = 3

Step 3: Find the mean of the absolute differences

Mean absolute deviation = (3+2+1+3+4+5+1+3)/8

Mean absolute deviation = 22/8

Mean absolute deviation = 2.75

Therefore, the mean absolute deviation for the given data set is 2.75.

The electricity cost for the Val's AC to run for a summer month of 30 days is $84.

Given that,

Val's whole-house central air conditioner uses 4,000 watts when running.

Val runs the AC 7 hours per summer day.

Electricity costs (10 cents)/(1 kilowatt-hour).

Total electricity used for the whole house = 4000 watts = 4 kilowatts

Number of hours that the AC runs = 7 hours

Cost of electricity = (10 cents)/(1 kilowatt-hour).

Cost of electricity for 4 kilowatts for 1 hour = 10 × 4 = 40 cents

Cost of electricity for 4 kilowatts for 7 hours = 40 × 7 = 280 cents

                                                                                       = $2.80

Cost of electricity for a summer month of 30 days = $2.80 × 30

                                                                                   = $84
