200 physics textbooks and 122 math textbooks were sold.

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants.

Let's use variables to represent the number of physics and math textbooks sold. We can call the number of physics textbooks "p" and the number of math textbooks "m".

From the problem, we know that the total number of textbooks sold is 322, so we can write:

p + m = 322

We also know that the number of math textbooks sold was 78 less than the number of physics textbooks sold. In other words, we can write:

m = p - 78

Now we can substitute the second equation into the first equation to eliminate "m" and solve for "p":

p + (p - 78) = 322

2p - 78 = 322

2p = 400

p = 200

So 200 physics textbooks were sold. To find the number of math textbooks sold, we can substitute this value of "p" back into the equation we used earlier:

m = p - 78

m = 200 - 78

m = 122

Therefore, 122 math textbooks were sold.

To check our work, we can verify that the sum of the number of physics and math textbooks sold is indeed 322:

200 + 122 = 322

So our solution is correct.

Therefore, 200 physics textbooks and 122 math textbooks were sold.

Answer:

The length of the diagonal of the rectangle is of \(\sqrt{58}\) units.

Step-by-step explanation:

Pythagorean theorem:

The square of the hypothenuse h is equal to the sum of the squares of sides a and b, that is:

\(h^2 = a^2 + b^2\)

Diagonal of a rectangle:

The diagonal is the hypothenuse, while the sides are a and b.

In this question:

The height has coordinates are y = 9 and y = 12, so the height is \(a = 12 - 9 = 3\)

The length has coordinates at \(x = -6, x = -13\), so the length is \(b = -6 - (-13) = 7\)

Diagonal:

\(d^2 = a^2 + b^2\)

\(d^2 = 3^2 + 7^2\)

\(d^2 = 9 + 49\)

\(d^2 = 58\)

\(d = \sqrt{58}\)

The length of the diagonal of the rectangle is of \(\sqrt{58}\) units.

Answer:

\(\sqrt3\)

Step-by-step explanation:

I'm assuming you're dealing with degrees.

If that's the case, then I would first find the closest multiple of 360 to that number.

360*20 = 7200, which is a bit too high; 360*19 = 6840, still a bit too high; 360*18 = 6480, perfect.

Now, just subtract 6480 from 6720 and you will get 240.

The answer is now simplified to tan 240, which can be expressed as sin(240)/cos(240).

240 degrees is 30 degrees away from 270, creating a 30-60-90 triangle.

That means cos(240) is -1/2 and sin(240) is -sqrt(3)/2.

Now, just divide:

\(-\frac{\sqrt3}{2}/-\frac{1}{2} = -\frac{\sqrt3}{2}\cdot-2 = \sqrt{3}\)

Therefore, tan(6720 degrees) = \(\sqrt3\)

The value of K in the given equations 6x+4y=7 and Kx+8y=7 is k=(-4y/x)+6.

Two things are equal, according to an equation.

It will be written with the equals sign "=" as in x+2=6.

What is on the left (x + 2) is equal to what is on the right ((6)), according to that equation.

A remark like "this equals that" can be compared to an equation.

So, we have the equations:

6x + 4y = 7

Kx + 8y = 7

Now, we know that both equations are equal to 7. so, we can write it as:

6x + 4y = Kx + 8y

Solve with subject K as follows:

6x + 4y = Kx + 8y

Kx - 6x  = 4y - 8y

(K-6)x = -4y

k-6 = -4y/x

k = (-4y/x) + 6

Therefore, the value of K in the given equations 6x+4y=7 and Kx+8y=7 is k=(-4y/x)+6.

The price after the markdown is 36 dollars.

Step-by-step explanation:

First, I found out what 10% of 45 is by moving the decimal point 1 time to the left, getting 4.5. Then I multiplied each value by 2 to get 20% and 9, meaning that 20% of 45 is 9. Then 1 subtracted 9 from 45 to get 36.

The function m(x) = 2tan(3x+4) is obtained by applying a sequence of transformations to the parent tangent function.

To determine the sequence of transformations, let's break down the given function:

1. Inside the tangent function, we have the expression (3x+4). This represents a horizontal compression and translation.

2. The coefficient 3 in front of x causes the function to compress horizontally by a factor of 1/3. This means that the period of the function is shortened to one-third of the parent tangent function's period.

3. The constant term 4 inside the parentheses shifts the function horizontally to the left by 4 units. So, the graph of the function is shifted to the left by 4 units.

4. Outside the tangent function, we have the coefficient 2. This represents a vertical stretch.

5. The coefficient 2 multiplies the output of the tangent function by 2, resulting in a vertical stretch. This means that the graph of the function is stretched vertically by a factor of 2.

In summary, the sequence of transformations applied to the parent tangent function to create the function m(x) = 2tan(3x+4) is a horizontal compression by a factor of 1/3, a horizontal shift to the left by 4 units, and a vertical stretch by a factor of 2.

Example:
Let's consider a point on the parent tangent function, such as (0,0), which lies on the x-axis.

After applying the transformations, the corresponding point on the function m(x) = 2tan(3x+4) would be:
(0,0) -> (0,0) (since there is no vertical shift in this case)

This example helps illustrate the effect of the transformations on the graph of the function.

If x and y be  i.i.d. unif(0, 1), then the covariance of x + y and x - y is zero

Here  x and y be i.i.d. unif(0, 1)

The i.i.d stands for independent and identically distributed

unif means that the uniformly distributed

Here x and y are i.i.d unif (0,1)

The covariance is defined as the relationship between the two random variables . Therefore, variance of one variable is equal to the change in another variable

Here we have to find the covariance of x + y and x - y

According to the properties of covariance

Cov(x+ y, x - y) = Cov (x, x) + Cov(y, x) - Cov(x, y) - Cov(y, y) = 0

a. The probability that a student scored below 91 on this exam is 0.9878

b. The probability that a student scored between 65 and 89 is 0.8186.

c. A grade of 68 on the second exam is better than a grade of 81 on the first exam for the given conditions

a. To find the probability that a student scored below 91 on the exam, we need to find the area under the normal distribution curve to the left of 91. Using a standard normal distribution table or calculator, we can find the corresponding Z-score as:

Z = (91 - 73) / 8 = 2.25

The probability of scoring below 91 is then the same as the probability of a standard normal random variable being less than 2.25, which is approximately 0.9878.

b. To find the probability that a student scored between 65 and 89, we need to find the area under the normal distribution curve between these two values. Using the Z-score formula as above, we find:

Z1 = (65 - 73) / 8 = -1.00

Z2 = (89 - 73) / 8 = 2.00

Using a standard normal distribution table or calculator, we can find the probability of a standard normal random variable being between -1.00 and 2.00, which is approximately 0.8186.

c. To determine if a grade of 81 on this exam or a grade of 68 on a different exam is better if the professor grades on a curve, we need to find the Z-score that corresponds to the top 10% of the class. Using a standard normal distribution table or calculator, we can find this Z-score as:

Z = 1.28 (approximately)

For the first exam, the Z-score corresponding to a grade of 81 is:

Z = (81 - 73) / 8 = 1.00

Since 1.00 < 1.28, a grade of 81 is not in the top 10% of the class. For the second exam, the Z-score corresponding to a grade of 68 is:

Z = (68 - 62) / 3 = 2.00

Since 2.00 > 1.28, a grade of 68 is in the top 10% of the class. Therefore, if the professor grades on a curve, a grade of 68 on the second exam is better than a grade of 81 on the first exam.

The probability that more than 40% of people in a randomly selected group of 100 working Canadians have income less than $20000 is 0.9867.

The relationship between a value and a set of values' mean is described by the statistical measurement known as the Z-score. Standard deviations from the mean are used to measure Z-score. A Z-score of zero means the data point's score is the same as the mean score. A value that is one standard deviation from the mean would have a Z-score of 1.0. Z-scores can be either positive or negative, with a positive number signifying a score above the mean and a negative value signifying a score below the mean.

Given that,

p = 0.3

n = 100

μ = p = 0.3

The margin of error is calculated as:

σ = √p (1-p)/n

σ = √(0.3)(1 - 0.3)/100

σ = 0.045

The z- score is given as:

z = m - μ / σ

z = 0.40 - 0.30/ 0.045

z = 2.22

P (p < 0.40) = P (z < 2.22)

P (z < 2.22) = 0.9867

Hence, the probability that more than 40% of people in a randomly selected group of 100 working Canadians have income less than $20000 is 0.9867.

Answer:

Step-by-step explanation:

Numbers begin with ‘8’:

Integers from 800 to 899; that is 100 numbers.

Numbers end with ‘8’ from 600 to 900:

Options for hundred's place = 3 (digits ‘6’, ‘7’ and ‘8’).

Options for ten's place = 10 (all ten digits)

Options for unit's place = 1 (only ‘8’)

So, (3 * 10 * 1) = 30 numbers.

Now, among these (100 + 30) = 130 numbers; there are some which start and end with ‘8’; we need to eliminate them to avoid ‘double counting’ of these numbers. How many are they?

Numbers start and end with ‘8’:

Option for hundred's place = 1 (Only ‘8’)

Options for ten's place = 10 (all ten digits)

Option for unit's place = 1 (only ‘8’)

So, (1 * 10 * 1) = 10 numbers.

Therefore, there are (130 - 10) = 120 numbers from 600 to 900 which either start with ‘8’ or end with ‘8’.
