The median is 10 as the value 10 is at 10th position.

What is Median?

The median is the value that separates the upper and lower halves of a data sample, population, or probability distribution in statistics and probability theory. It is sometimes referred to as "the middle" value in a data collection.

Solution:

Firstly we need to arrange the data in ascending order

6,6,6,7,7,7,8,8,10,10,10,10,10,10,10,10,10,88,88

the total number of digits are

n = 19

So, the middle value that divide the data in two halves will be at n = 10

The colored type of led is more expensive if you order 3 strings of white led lights and 2 strings of colored led lights for 66$.

An equation in French is defined as having one or more variables, whereas an equation in English is any well-formed formula consisting of two expressions combined with an equals sign.

Solving a variable equation includes determining which variables' values result in equality. Unknowns are the variables for which the equation must be solved, while equation solutions are the unknown values that satisfy the equality. An equation is a mathematical phrase with two equal sides separated by an equal sign. An equation is 4 + 6 = 10. We can see 4 + 6 on the left side of the equal sign and 10 on the right.

First type of white led have 3 strings=3x

Second type of colored led have 2 strings and bought only one string=2y

The total cost =3x+2y=66    ----------->(1)

In the second order ,

Each string brought only one=x+y=27 ------->(2)

Solving equations 1 and 2

From eq2, y=27-x

3x+2(27-x)=66

x = amount of the 80% broth

y = amount of water with 0% broth

keeping in mind that water has no broth in it, so 0% of broth, let's plug in those percentages in decimal format to see how much each one has.

what's 80% of "x"? well (8/100) * x = 0.80x.

what's 0% of "y"?  well hell is just 0.

what's 60% of 200? well anyhow is just 120.

The value of x in the right triangle is x = 9 or x = 12.

The right angle triangle is a triangle with one of its angles as 90 degrees. The sides of a right angle triangle can be found using Pythagoras's theorem.

Hence,

c² = a² + b²

where

Therefore, the equation to show the relationships between the three sides can be gotten by applying Pythagoras's theorem.

x² + (21 - x)² = 15²

x² + (21 - x)(21 - x) = 225

x² + 441 - 21x - 21x + x² = 225

2x² - 42x + 441 - 225 = 0

2x² - 42x + 216 = 0

divide through by 2

x² - 21x + 108 = 0

Let's find the value of x by factoring.

x² - 21x + 108 = 0

x² - 12x - 9x + 108 = 0

x(x - 12) - 9(x - 12) = 0

(x - 9)(x - 12) = 0

For the given set of equations x/2 + y/3 = 1 and x/4 + 2y/3 = -1 the sum of x and y is 1.

An equation is a combination of different variables, in which two mathematical expressions are equal to each other.

The given set of equations are,

x/2 + y/3 = 1,        

x/4 + 2y/3 = -1.

Simplify both the equations,

3x + 2y = 6         (1)

3x + 8y = -12       (2)

Subtract equation (2) and (1),

6y = -18

y = -3

Substitute the value of y = -3, in equation (1)

3x + 2(-3) = 6

3x - 6 = 6

3x = 12

x = 4

The sum of x and y,

Step-by-step explanation: Step by step solution for calculating 135 is 0.9 percent of what number

We already have our first value of 135 and the second value of 0.9. Let's assume the unknown value is Y which answer we will find out.

As we have all the required values we need, Now we can put them in a simple mathematical formula as below:

STEP 1135 = 0.9% × Y

STEP 2135 =

0.9

100

× Y

Multiplying both sides by 100 and dividing both sides of the equation by 0.9 we will arrive at:

STEP 3Y = 135 ×

100

0.9

STEP 4Y = 135 × 100 ÷ 0.9

STEP 5Y = 15000

Finally, we have found the value of Y which is 15000 and that is our answer.

You can easily calculate 135 is 0.9 percent of what number by using any regular calculator, simply enter 135 × 100 ÷ 0.9 and you will get your answer which is 15000

The time that has elapsed before the body was found is 1.5 hour

Newton's law of cooling states that the rate of heat loss from a body is inversely related to the temperature difference between the body and its surroundings.

Given:

when time, t = 0, temperature = 98.6 ⁰F

when time, t = 1, temperature = 75⁰

when time,  t = t, temperature = 80⁰

By Newton's method of cooling equation;

T(t) = [tex]T_s (T_0 - T_s)e^{kt[/tex]

T(t) = 70+  28.6[tex]e^{kt[/tex]

Now, At the time of discovery

80 = 70+  28.6[tex]e^{kt[/tex]

10= 28.6[tex]e^{kt[/tex]

Then, 1 hour later( t + 1) we have the second equation;

75= 70 + 28.6[tex]e^{kt[/tex]

28.6[tex]e^{kt[/tex] = 5

Now, divide equation 1  by equation 2;

2= [tex]e^{-k[/tex]

k = -0.693

The time when he dead body was discovered

10= 28.6[tex]e^{kt[/tex]

10= 28.6[tex]e^{-0.693[/tex]

-0.693t = ln (10 /28.6)

-0.693t = -1.05

t= 1.5 hour

The predicted quantity of balls in the first bin is (1/n)n.

Considering that,

There are the same number of balls and containers.

If so, then each container must always contain one ball. The probability of each ball landing in the first bin is (1/n)n.

For instance -

Three balls and three bins should be present. Next to each ball, place an A, B, and C. There are numbers 1, 2, and 3 on the containers. Ball A has a 1/3 chance of landing in bin 1. Although there is a 1/3 probability that ball B will drop in bin 1 and a 1/3 chance that ball C will do the same, both outcomes are possible. Therefore, bin 1 should be equal to 1/3 + 1/3 + 1/3. The rationale behind the projected values of bins 2 and 3 is identical.

According to the same logic, bins 2 and 3 should also have expected values of 1.

How probable is it that the first bin will receive all three balls?

In general, (1/n)n, which equals (1/3)3, or 1/3 x 1/3 x 1/3, equals 1/27.

Therefore, (1/n)n would be the expected number of balls in the first bin.

The answers to both the subparts using the inversely proportional property are shown:

(A) The formula will be: M = 375/g³

(B) The value of g is 15 when M = 1/9.

When one variable decline, the others also decline in the same ratio.

When two variables move in opposite directions, one variable reduces as another increase, and the other increases as another variable lower, the variables are said to be inversely proportional.

Since M and g3 have an inverse relationship, we can say:

M = k/g^3

Assuming that g = 2.5 and that M = 24 then:

24 = k/(2.5)^3

24*(2.5)^3 = k = 375

(A) Formula for M in terms of G:

The formula will be M = 375/g³.

(B) Value of G when M = 1/9:

If M = 1/9, we get:

1/9 = 375/g^3

g^3 = 9*375

g = ∛(9*375) = 15

Therefore, the value of g is 15 when M = 1/9.

Therefore, the answers to both the subparts using the inverse proportional property are shown:

(A) The formula will be: M = 375/g³
