The given expression 2x+3y =- 9 is compared with the general form y=mx+c. And the slope is -2/3.

A line's direction and steepness are both expressed by a numerical value called the slope or gradient of the line. It provides the ratio of how much that y increases when x increases by a certain amount. This is therefore given by the general expression y=mx+c where y-intercept is denoted by c and slope by m.

First, subtracting both sides of the given expression by 2x, we get,

[tex]\begin{aligned}2x + 3y - 2x &= -9 - 2x \\3y &= -9 - 2x\end{aligned}[/tex]

Now divide the above expression by 3, and we get,

[tex]\begin{aligned}y=-3-\frac{2x}{3}\end{aligned}[/tex]

Comparing the above expression with the general form of the slope, we get the slope as  -2/3.

Mixture is kept undisturbed for some time. After some time, sand being heavier and insoluble in water, settles down at the bottom of container.

Sand and water are separated in this situation using filtering. The filter funnel, which is lined with filter paper, is filled with the sand and water mixture.

The paper allows the water to escape and accumulate in the beaker. Sand particles build up in the filter funnel because they can't pass through the filter paper. One of humankind's first methods of water treatment, distillation desalination is still a widely used treatment method today.

Many ancient civilizations employed this method to turn seawater into drinkable water aboard their ships. The differing densities of salt and sand are the basis for another physical separation technique. Sand has a density of 2.65 g/cm3, but salt has a density of 2.16 g/cm3.

The probability that a student, chosen at random, does not study Chemistry is 0.49.

What is Probability?

Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is.

From the Venn diagram -

The number of students that study biology and physics = 2

The number of students that study biology and chemistry = 6

The number of students that study chemistry and physics = 4

The number of students that study only physics = 5

The number of students that study only biology = 7

The number of students that study only chemistry = 8

The number of students that study all the subjects = 3

The number of students that study none = 6

So, the total number of students a = 2 + 6 + 4 + 5 + 7 + 8 + 3 + 6 = 41

The number of students that study chemistry = 8 + 6 + 3 + 4 = 21

The number of students that do not study chemistry b = 41 - 21 = 20 students

The probability chosen at random that child does not study chemistry =  b/a -

= 20/41

= 0.49

Therefore, the probability value is 0.49.

Answer:

The sentence "Eight more than the quotient of a number and 4 equals 5" can be translated into the following equation:

(b / 4) + 8 = 5

Where b is the unknown number, and 4 is the divisor.

Answer:

b = - 12

Step-by-step explanation:

let the number be b

the quotient ( division ) of b and 4 is [tex]\frac{b}{4}[/tex] , then

[tex]\frac{b}{4}[/tex] + 8 = 5 ← equation

to solve for b

subtract 8 from both sides

[tex]\frac{b}{4}[/tex] = - 3 ( multiply both sides by 4 to clear the fraction )

Optimal allocation for estimating the population mean is 16.7 and 83.7 sample units.

Optimal allocation for estimating the difference of the means of the strata,μH-μL is 26.4 and 73.6 sample units.

a) To find the optimal allocation for estimating the population mean, we want to minimize the variance of the estimator. One common method for this is to use the proportional allocation, where the proportion of the sample allocated to each stratum is equal to the proportion of the population in that stratum.

In this case, the proportion of the population in stratum h is 100,000 / (100,000 + 500,000) = 0.167, and the proportion of the population in stratum L is 1 - 0.167 = 0.833.

So, the optimal allocation for estimating the population mean would be:

Stratum h: 16.7% of the sample, or 16.7% * 100 = 16.7 sample units

Stratum L: 83.3% of the sample, or 83.3% * 100 = 83.3 sample units

b) To find the optimal allocation for estimating the difference of the means of the strata, μH-μL, we again want to minimize the variance of the estimator. One method to achieve this is to use the Neyman allocation, where the sample size is allocated to each stratum in such a way that the variance of the estimator is minimized.

To do this, we need to know the variances of the strata, which are given as 20^2 and 12^2 respectively. The optimal allocation is given by the ratio of the variances, which is:

(12^2) / (20^2 + 12^2) = 144/544 = 0.264

So, the optimal allocation for estimating the difference of the means of the strata is:

Stratum h: 26.4% of the sample, or 26.4% * 100 = 26.4 sample units

Stratum L: 73.6% of the sample, or 73.6% * 100 = 73.6 sample units

What is exponential power?

In mathematics, power defines a base number raised to the exponent, where the base number is the factor that is multiplied by itself and the exponent denotes the number of times the same base number is multiplied.

To solve 5³ * 5⁻⁷, we can simplify the exponents first:

5³ = 125

5⁻⁷ = 1 / 5⁷

So, the expression simplifies to:

125 * (1 / 5⁷) = 125 / 78125

To solve 6⁴ * 6⁻⁵, we can simplify the exponents first:

6⁴ = 1296

6⁻⁵ = 1 / 6⁵

So, the expression simplifies to:

1296 * (1 / 6⁵) = 1296 / 7776

The degree of polynomial 2x^2 + 5x^3 + 7 is 3.

The degree of a polynomial is the highest power of the variable in the polynomial.

The degree of a polynomial gives us an idea of how quickly the value of the polynomial changes as the input (x) changes. A polynomial of degree n will change more quickly than a polynomial of degree n-1. In this case, the polynomial 2x^2 + 5x^3 + 7 is a polynomial of degree 3.

In the polynomial 2x^2 + 5x^3 + 7, the highest power of the variable x is 3, which is in the term 5x^3. Therefore, the degree of the polynomial is 3.

It's important to note that the constant term 7 does not affect the degree of the polynomial as it does not have a variable x in it.

Where x represents the number of days on the medicine.

y represents the weight gain, in pounds.

The slope intercept form is y = mx + b, where m is slope.

So, the slope of y = 0.7x is m = 0.7.

If x = 2 , then y will be -

y = 0.7(2)

y = 1.4

If x = 3 , then y will be -
