Answer:

102

Step-by-step explanation:

The median of a data set is found by putting the data set in ascending numerical order and identifying the middle number. If there are an odd number of data values in the data set, the median is a single number. If there are an even number of data values in the data set, the median is the average of the two middle numbers. Sorting the data set for the values entered above we have:

65 , 67 , 78 , 80 , 88 , 102 , 105 , 110 ,119 , 126 , 134

Since there is an odd number of data values in this data set, there is only one middle number. With 11 data values, the middle number is the data value at position 6. Therefore, the median is 102.

Answer:

102

Step-by-step explanation:

1. The median is the quantity that's in the middle of a data set.

2. First, we have to arrange the given data set from least to greatest:

3. Now, when we try and locate the middle number, we can see that the number is 102.

Therefore, the median is 102.

Answer:

[tex]\frac{8}{15}[/tex] of a mile

Step-by-step explanation:

To find a segment of a fraction, you must first find the LCM of each value's denominator:

LCM - Lowest Common Multiple

The lowest common multiple is the number that shows up first in each number's multiple set.

Example: LCM of 4 and 6

Multiples of 4: 4, 8, 12, 16, 20

Multiples of 6: 6, 12, 18, 24, 30

Because 12 is the first number to show up in each multiple set, 12 is the LCM.

So, to be able to solve this problem easy, do the same with 5 and 3:

5, 10, 15, 20, 25

3, 6, 9, 12, 15

Since 15 is the first number in both sets, 15 is the LCM.

The next step is to multiply [tex]\frac{4}{5}[/tex] by [tex]\frac{x}{x}[/tex], x being the value that can be multiplied with the denominator to equal 15:

[tex]\frac{4}{5}[/tex] × [tex]\frac{3}{3}[/tex] = [tex]\frac{12}{15}[/tex]

To find how much [tex]\frac{2}{3}[/tex] of [tex]\frac{12}{15}[/tex] is, multiply the fractions together:

[tex]\frac{12}{15}[/tex] × [tex]\frac{2}{3}[/tex] = [tex]\frac{24}{45}[/tex]          

Simplify the fraction by dividing the numerator and denominator by 3.

[tex]\frac{24}{45}[/tex] ÷ [tex]\frac{3}{3}[/tex] = [tex]\frac{8}{15}[/tex]

Because the fraction can't be simplified any further, Aimee has walked a total of [tex]\frac{8}{15}[/tex] of a mile.

Rates of change are the change of a quantity over another.

The rate of change in height of the water level is 36.51 cm per second.

Let the length of the top square be s, and the height be h.

The volume of the pyramid is:

[tex]\mathbf{V = \frac{1}{3}s^2h}[/tex]

At time t, we have:

[tex]\mathbf{V = \frac{1}{3}s(t)^2h(t)}[/tex]

The relationship between the side length and height is:

[tex]\mathbf{s : h=6 : 13}[/tex]

Express as fractions

[tex]\mathbf{\frac{s }{ h}=\frac{6 }{ 13}}[/tex]

Make s the subject

[tex]\mathbf{s=\frac{6 }{ 13}h}[/tex]

So, we have:

[tex]\mathbf{V = \frac{1}{3}s^2(t)h(t)}[/tex]

[tex]\mathbf{V = \frac{1}{3} \times (\frac{6 }{ 13}h(t))^2 \times h(t)}[/tex]

[tex]\mathbf{V = \frac{1}{3} \times \frac{36}{ 169}h^2(t) \times h(t)}[/tex]

[tex]\mathbf{V = \frac{1}{3} \times \frac{36}{ 169}h^3(t)}[/tex]

Differentiate

[tex]\mathbf{V'(t) =3 \times \frac{1}{3} \times \frac{36}{ 169}h^2(t) \times h'(t)}[/tex]

[tex]\mathbf{V'(t) =\frac{36}{ 169}h^2(t) \times h'(t)}[/tex]

Make h'(t) the subject

[tex]\mathbf{h'(t) = \frac{169 \times V'(t)}{36 \times h^2(t)}}[/tex]

The water level rises constantly at 70 cm^3/s, and the water level is 3 cm.

So, we have:

[tex]\mathbf{V'(t) = 70}[/tex]

[tex]\mathbf{h(t) = 3}[/tex]

[tex]\mathbf{h'(t) = \frac{169 \times V'(t)}{36 \times h^2(t)}}[/tex] becomes

[tex]\mathbf{h'(t) = \frac{169 \times 70}{36 \times 3^2}}[/tex]

[tex]\mathbf{h'(t) = \frac{169 \times 70}{36 \times 9}}[/tex]

[tex]\mathbf{h'(t) = 36.51}[/tex]

Hence, the rate of change in height of the water level is 36.51 cm per second.

Answer: 2.66 standard deviations above the mean

Explanation:

The z score directly determines how far we are from the mean. For positive z values, we are above the mean, while negative z values are below the mean.

The mean itself is z = 0

The absolute value of the z score is the distance from the score to 0. So having a z score of z = 2.66 means we are 2.66 standard deviations above the mean. Something like z = -2 means we are 2 standard deviations below the mean.

Answer:

$10.00

Step-by-step explanation:

there are 6 tshirts sold and the total cost is 59.98 dollars, so you would divide 59.98 divided by 6. you would probably round because the answer would be 9.996667, rounding up would be 10.00. hope this helps a bit

Answer:

Step-by-step explanation:

12    Cost(1.779) = 74.11

      Cost = 74.11 / 1.779

       Cost = $41.66

Markup = 41.66(0.779) = $32.45

or

Markup = 74.11 - 41.66 = $32.45

The factors which can represent the length and width of the container are; 2x − 1 and x + 3.

The Volume of a rectangular prism is a three-dimensional quantity and is the product of its length, width and height.

In essence;

However, V = 2x3 + 5x2 − 3x and height, h = x.

Therefore; V/h = l × w
