a list of measurements in increasing order is 4, 5, 6, 8, 10, and x . if the median of these measurements is ​six sevenths​ times their arithmetic mean, what is the value of x ?

Answers

In a list of measurements in increasing order: 4, 5, 6, 8, 10, and x, the value of x is 16.

To get the value of x, we will use algebraic expressions to demonstrate the given relationships.

If the median of these measurements is ​six sevenths​ times their arithmetic mean, then:

median = 6/7 x mean

Median (Md), is a single value at the middle of the data values arranged in increasing or decreasing order. On the other hand, arithmetic mean (μ) is the sum of the data values divided by its total number.

For the list of measurements in increasing order is 4, 5, 6, 8, 10, and x,

The median is between 6 and 8.

Md = 6+8/2

Md = 7

Evaluating the first equation using Md = 7:

median = 6/7 x mean

7 = 6/7 x mean

mean = 49/6

By definition,

mean = (4 + 5 + 6 + 8 + 10 + x)/6

Equating both equations for the mean:

49/6 = (4 + 5 + 6 + 8 + 10 + x)/6

49 = 33 + x

x = 16

Hence, the value of x is 16.

A sled team consists of 11 dogs and the musher. Each dog weighs 70 pounds and the musher weighs 160 pounds. What is the average weight of the sled team members?

a
68.5 pounds
b
115 pounds
c
73.5 pounds
d
77.5 pounds

Answers

The average weight of the sled team members is 77.5

What is an average value?

Average value can be calculated by finding the  sum of a set of numbers  then count the total number, then divide the sum with the  number of the counted values.

To calculate the average weight of the sled team members, then we know that there are  11 dogs and the musher, which implies that there are total number of 12 animals.

Then we can find the total number of the dogs as (11*70) =770 dogs, then we can add to the musher which makes the total number of (770+160)=930

Then the average weight of the sled team members is [tex]\frac{930}{12} =77.5[/tex]

the owner of the good deals store opens a new store across town. for the new store, the owner estimates that, during business hours, an average of 909090 shoppers per hour enter the store and each of them stays an average of 121212 minutes. the average number of shoppers in the new store at any time is what percent less than the average number of shoppers in the original store at any time? (note: ignore the percent symbol when entering your answer. for example, if the answer is 42.1\b.1b, point, 1, percent, enter 42.142.142, point, 1.)

Answers

The answer is 60%

According to the original information given, the estimated average number of shoppers in the original store at any time(x) is 45.

In the question, it states that, in the new store, the manager estimates that an average of 90 shoppers per hour(60 minutes) enter the store, which is equivalent to 1.5 shoppers per minute(s).

The manager also estimates that each shoppers stays in the store for an average of 12 minute (t). Thus, by Little's law there are, on average,

x = s x t

=> x = 1.5 x 12

=> x = 18

Hence, there are 18 shoppers at any time in the new store.

Now, Percentage of shoppers

Answers

For the given quadratic function we have that:

Domain: Set of all real values.Range: y ≤ 3.

What is the domain and range of the quadratic function?

For a function h(x), we define the domain as the set of the inputs (values of x) and the range is the set of the outputs (values of y).

Generally, for all quadratic functions, the domain is the set of all real numbers, so we already know the domain.

Now let's look at the range.

The given function is:

h(x) = -12*(x - 4)^2 + 3

Remember that if a quadratic function has a vertex (h, k), then the vertex form is:

f(x) = A*(x - h)^2 + k

So the vertex here is (4, 3)

And we also can see that the leading coefficient of the quadratic function is negative. This means that the function opens downwards, so the vertex is the maximum.

Then the range is the set of all real values smaller than or equal to 3, then the range is:

R: y ≤ 3.

Concluding:

Domain: Set of all real values.Range: y ≤ 3.

select translation, reflection, or rotation to identify the single transformation that transforms ∆rst to ∆r′s′t′.

Answers

The single transformation that transforms ∆RST to ∆R'S'T' is a reflection.

Part A:

For the first figure it is visible that the orientation of the pre-image (∆RST) is similar to that of the image (∆R'S'T').The image is received from the pre-image through moving the pre-image a few units down. Therefore, the single transformation that transforms ∆RST to ∆R'S'T' is a translation.

Part B:

For the second figure ,it is visible that the orientation of the pre-image (∆RST) is similar to that of the image (∆R'S'T').The image is received from the pre-image through moving the pre-image a few units down and a few units to the right. Therefore, the single transformation that transforms ∆RST to ∆R'S'T' is a translation.

Part C:

For the third figure it is visible that the orientation of the pre-image (∆RST) isn't similar to that of the image (∆R'S'T').The image is received from the pre-image through rotating the pre-image a few 180 degrees. Therefore, the single transformation that transforms ∆RST to ∆R'S'T' is a rotation.

Part D:

For the fourth figure it is  visible that the orientation of the pre-image (∆RST) isn't similar to that of the photograph (∆R'S'T').The image is received from the pre-image through reflecting the pre-image.

The money made from mezzanine tickets alone was 4 times the money made from upper balcony tickets. How many lower level tickets were sold for that performance?

Answers

Based on the calculation done below, the number of lower level tickets sold is 750.

How do we calculate the number of units sold from a word problem?

Let:

L = number of lower-level tickets sold = 5U

M = number of mezzanine tickets sold

U = number of upper balcony tickets sold

We therefore have:

35L + 25M + 15U = 37,500 ...................... (1)

25M = 4 * 15U = 60U

Substituting L = 5U and 25M = 60U into equation (1) and solve for U, we have:

35(5U) + 60U + 15U = 37,500

175U + 60U + 15U = 37,500

250U = 37,500

U = 37,500 / 250

U = 150

what percent of 54 is 23? explained

Answers

Answer: 42.59

Step-by-step explanation:

Step 1: First, write the problem as an equation: P% = X/Y

Step 2: Here, X is 23, Y is 54, so the equation is P% = 23/54

Step 3: A percent is a ratio of a number expressed out of 100. So P% means P/100

Step 4: Substitute P/100 instead of P% in the above equation, then P% = 23/54 becomes P/100 = 23/54

Step 5: Solve for P

P/100 = 23/54

P = (23/54) * 100 = 42.59

Therefore, 23 is 42.59 percent of 54
