A data set has many very large data values, then the mean will be larger than the median. The correct option is a.

In a dataset with large values, the mean is influenced by outliers and extreme values, whereas the median is not. The median is the value that divides the data into two equal halves, while the mean is calculated by summing up all values and dividing by the total number of values.

Thus, in a skewed dataset with large values, the mean tends to be pulled towards the larger values, resulting in a larger mean than the median. This effect is more pronounced in datasets with a high variance. Therefore, option (a) is the correct answer.

The total cost after discount and tax is $46.28.

To find the total cost after the discount and tax, we need to first find the subtotal before tax.

Fred bought two pairs of jeans for $17.99 each, so the cost of the jeans is $17.99 x 2 = $35.98.

He also bought three shirts at $5.99 each, so the cost of the shirts is $5.99 x 3 = $17.97.

The pack of socks costs $3.

The subtotal before discount is $35.98 + $17.97 + $3 = $57.95.

With the 25% off coupon, Fred gets a discount of $57.95 x 0.25 = $14.49.

The new subtotal after discount is $57.95 - $14.49 = $43.46.

Finally, we need to add the 6.5% sales tax.

The sales tax is $43.46 x 0.065 = $2.82.

The total cost after discount and tax is $43.46 + $2.82 = $46.28.

Therefore, the closest answer is C: $45.49.

The exact value of the trigonometric function is cos θ = (√3 + 1) / 2√2.

In this problem we find the exact value of a trigonometric function, from which we need to determine the exact value of another trigonometric function. This can be done by using definitions of trigonometric functions:

The product of the middle two sums is greater than or equal to the product of the least and the greatest of the sums.

To compare two products, we need to compare the values of the products using the comparison operators (<, >, <=, >=, or =).

We can start by finding the sums of the original numbers (0, 1, 2, 3):

Sum of the original numbers = 0 + 1 + 2 + 3 = 6

Now, we add the number k to each of the numbers:

Sum of the new numbers = (0 + k) + (1 + k) + (2 + k) + (3 + k)

= (0 + 1 + 2 + 3) + 4k

= 6 + 4k

So, the new sums range from 6 + 4k (the smallest) to 9 + 4k (the largest).

The product of the least and the greatest of the sums is:

(6 + 4k) × (9 + 4k) = 54 + 60k + 16k^2

The product of the middle two sums is:

(7 + 4k) × (8 + 4k) = 56 + 60k + 16k^2

Comparing the two products using the comparison operators:

54 + 60k + 16k^2 < 56 + 60k + 16k^2 (since 54 < 56)

or

54 + 60k + 16k^2 <= 56 + 60k + 16k^2 (since the products are equal when k=0)

In conclusion, the product of the middle two sums is greater than or equal to the product of the least and the greatest of the sums.

The measure of the trade places with any opponent region is 30°

Let the measure of the trade places with any opponent = x

Move two space is twice the angle as trade places with any opponent

Move two space = 2x

Move one space is three times the angle as moving two spaces

Move one space = 3(2x)

Move one space = 6x

Lose your turn is a quarter

Lose your turn = 90°

The sum of a complete angle = 360°

90 + x + 2x + 6x = 360°

9x = 360 - 90

(a) To find the curl of the vector field F(x, y, z), we first find its component functions:

F(x, y, z) = (5ex sin(y), 9ey sin(z), 2ez sin(x))

Then, we use the formula for the curl of a vector field:

curl F = (∂Fz/∂y - ∂Fy/∂z, ∂Fx/∂z - ∂Fz/∂x, ∂Fy/∂x - ∂Fx/∂y)

Plugging in the component functions of F(x, y, z), we get:

curl F = (2ez cos(x), -5ex cos(y), 9ey cos(z))

(b) To find the divergence of the vector field F(x, y, z), we use the formula for the divergence of a vector field:

div F = ∂Fx/∂x + ∂Fy/∂y + ∂Fz/∂z

Plugging in the component functions of F(x, y, z), we get:

div F = 5e^x sin(y) + 9e^y sin(z) + 2e^z sin(x)
(a) To find the curl of the vector field F(x, y, z) = (5e^x sin(y), 9e^y sin(z), 2e^z sin(x)), we need to compute the cross product of the del operator (∇) and F:

curl F = ∇ x F

curl F = ( (∂/∂y)(2e^z sin(x)) - (∂/∂z)(9e^y sin(z)), (∂/∂z)(5e^x sin(y)) - (∂/∂x)(2e^z sin(x)), (∂/∂x)(9e^y sin(z)) - (∂/∂y)(5e^x sin(y)) )

After computing the partial derivatives, we get:

curl F = ( 0, 5e^x cos(y) - 2e^z cos(x), 9e^y cos(z) - 5e^x cos(y) )

(b) To find the divergence of the vector field F(x, y, z), we need to compute the dot product of the del operator (∇) and F:

div F = (∂/∂x)(5e^x sin(y)) + (∂/∂y)(9e^y sin(z)) + (∂/∂z)(2e^z sin(x))

The conditions listed by the third student will result in more than one triangle because we are given all three angles. As a rule in math, some conditions will determine if there is more than one triangle. One of them is this:

Rule 1:

If all three angles of the triangle are given and they all add up to exactly 180°, it is possible to get more than one triangle.  In the third option, we are given angles 62°, 36°, and 82°, so different triangles can be constructed. Also, they all add up to give 180°. The condition is satisfied.

Rule 2:

Also, as a rule, if we have two angles that do not add up to 180° and one side, then only one unique triangle can be obtained. This is the case for student A who is given angles A and B and a side length of 5cm. (ASA)

There is an estimated probability of 0.875 (or 87.5%) that at least one of Esteban's kittens will still have blue eyes at three months old.

Let's use the complement rule to estimate the probability that at least one kitten will still have blue eyes at three months old:

P(at least one kitten with blue eyes) = 1 - P(no kitten with blue eyes)

To estimate P(no kitten with blue eyes), we can use the results of Esteban's simulation. We can see from the table that all three coins came up tails (representing no color change) in row 8, so that's one outcome where no kitten has blue eyes. There are a total of 2^3 = 8 possible outcomes, so the estimated probability of no kitten having blue eyes is:

P(no kitten with blue eyes) = 1/8 = 0.125

Therefore, the estimated probability that at least one kitten will still have blue eyes at three months old is:

P(at least one kitten with blue eyes) = 1 - P(no kitten with blue eyes) = 1 - 0.125 = 0.875

let's assumed that

y = 1h of parasailing

3h of horseback = 3x

2h of parasailing = 2y

and

2h of horseback = 2x

3h of parasailing = 3y

if

3x + 2y = 192

2x + 3y = 213

to find y we have to remove the x

(3x + 2y = 192) × 2

(2x + 3y = 213) × 3

6x + 4y = 384

6x + 9y = 639

___________ -

-5y = -255

y = 51

substitute y to any equation to find x

3x + 2y = 192

3x + 2(51) = 192

3x + 102 = 192

The fastest rate of growth that the foot experienced during the year is approximately 0.554 inches/year.

We can use the given relationship between foot length L and height h to determine the rate of change of foot length with respect to time. Taking the derivative of L with respect to time t, we have dL/dt = (3/4) * 0.5 * h^(-0.5) * dh/dt. We can then substitute the given values of L and h at the beginning and end of the growth spurt to find dh/dt.

At the start, h = 64 inches and L = (3/4) * 64^0.5 = 9 inches. At the end, h = 69 inches and L = (3/4) * 69^0.5 = 9.89 inches.

Solving for dh/dt, we have dh/dt = 2.4 inches/year. Substituting this value into the expression for dL/dt, we get dL/dt = (3/4) * 0.5 * 69^(-0.5) * 2.4 = 0.554 inches/year (rounded to three decimal places). Therefore, the fastest rate of growth that the foot experienced during the year is approximately 0.554 inches/year.

Step-by-step explanation:

In order to subtract fractions you first have to get a common denominator. The common denominator between 4 and 14 is 28 since 4(7) = 28 and 14(2) = 28. Then multiply the top and bottom of (1/4) by (7/7) and (5/14) by (2/2). This gives a common denominator and since you multiply by a fraction equal to 1, it doesn't change the value. Therefore, we get 7/28 - 10/28 = -3/28.

According to the law of proportion, two sets of given numbers are said to be directly proportional to one another if they grow or shrink in the same ratio.

Here cost of 1kg apples = 89.50

Then cost of 0.7 kg apple = x.

Now using proportion,
