If a data set has many very large data values, then the mean wil be
the median
a larger than
b. the same as
c. equal to
d. smaller than
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.

A hotel offers two activity packages. One costs $192 and includes 3h of horseback riding and 2h of parasailing. The second costs $213 and includes 2h of horseback riding and 3h of parasailing. What is the cost for 1h of each activity?
Answer:
Step-by-step explanation:
Step-by-step explanation:
let's assumed that
x = 1h of horseback
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
3x = 192 - 102
3x = 90
x = 30
so the answers are 1h of horseback = $30 and 1h of parasailing = $51

The answer is option B: (0.221-0.27).
Using the formula for a confidence interval for a proportion:
p± z*√(p(1-p)/n)
where p is the sample proportion (12/45 = 0.267), z* is the z-score for the desired confidence level (99% corresponds to a z-score of 2.576), and n is the sample size (45).
Substituting the values, we get:
0.267 ± 2.576*√(0.267(1-0.267)/45)
which simplifies to:
0.267 ± 0.195
Therefore, the 99% confidence interval for the true proportion of times the number cube would land with a six facing up is (0.072, 0.462).

? to 10
The completed table of equivalent ratios would be:
13.5 square meters : 3 liters of paint
4.5 square meters : 1 liter of paint
45 square meters : 10 liters of paint.
To find the missing ratios, we need to set up proportions using the given information.
13.5 square meters is covered by 3 liters of paint, so we can write:
13.5/3 = ?/1
To solve for the missing ratio, we can cross-multiply:
13.5 x 1 = 3 x ?
? = (13.5 x 1) / 3
? = 4.5
So, 4.5 square meters can be covered by 1 liter of paint.
To find the last missing ratio, we can use the same method:
13.5/3 = ?/10
10 x 13.5 = 3 x ?
? = (10 x 13.5) / 3
? = 45

The condition that will result in more than one triangle is C. Student III.
How the conditions will result in more than one triangleThe 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)

(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) )

Suppose that your foot length L in inches is related to your height h in inches by L=(3/4)h^0. 5
In one (non-leap) year, you have a growth spurt in which you grow from 64 inches to 69 inches. For simplicity of modeling, assume that your height changes at a constant rate throughout the year. What was the fastest rate of growth that your foot experienced during this time?
Answer for inch/year. Three digits after the decimal points after round off.
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.

Fred goes to Old Navy and buys two pairs of jeans for $17. 99 each, three shirts at $5. 99 each, and a pack of socks for $3. He has a coupon for 25% off his entire purchase. Sales tax is 6. 5%. What is the total cost after the discount and tax?
A: $43. 07
B: $39. 95
C: $45. 49
D: $60. 65
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.

How can the two products be compared?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.

what is ditribustion propety?
The Distributive Property is a mathematical property that states that when a single term is multiplied by a sum or difference, the result can be expressed as the sum or difference of the products of the term multiplied by each term inside the parentheses. It is often used to simplify expressions and equations in algebra. 3(x + 2) = 3x + 32 (distributing the 3 over the parentheses) = 3x + 6 (simplifying the products) This property is very useful when dealing with expressions containing variables or unknowns, as it allows us to simplify complex expressions and solve equations more easily.
