The value of (a)  125 / 78125 and  (b)  1296 / 7776.

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

Hence, The value of (a)  125 / 78125 and  (b)  1296 / 7776.

For the linear function y = 0.7x, option A: An additional day on the medicine is associated with 0.7 pounds of weight gain is the correct answer.

What is a linear function?

A linear function is a function that, when plotted, creates a straight line. Typically, it is a polynomial function with a maximum degree of 1 or 0. Nevertheless, calculus and linear algebra are also used to represent linear functions.

The given linear function is y = 0.7x.

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 -

y = 0.7(3)

y = 2.1

Therefore, it can be seen that when the number of days on the medicine is increased the weight gain also increases with 0.7 pounds.

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.

The ratios 40/18 and 27/11 are not equal because 20/9 and 3/1 are different fractions. They stand for various proportional connections between two quantities, in other words.

We need to see if the ratios of 40/18 and 27/11 fall to the same fraction when the numerator and denominator are both divided by their largest common factor (GCF).

Given that the GCF of 40 and 18 is 2, we can obtain 20/9 by reducing both the numerator and denominator of 40/18 by 2. Since the GCF of 27 and 11 is also 11, we obtain 3/1 when we divide the numerator and denominator of 27/11 by 11.

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.

(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

Answer: number c I think

Step-by-step explanation:

The domain function f/x )= x 1 is a mathematical expression that describes the relationship between an independent variable (x) and a dependent variable (f(x)).

The equation states that f(x) is equal to x minus 1. This means that for every value of x, there will be a corresponding value of f(x) that is one less than the value of x. For example, if x is 5, then f(x) will be 4; if x is 3, then f(x) will be 2; and so on.

Domain function f/x )= x 1 is a mathematical function that describes the relationship between a given input (x) and the output (f(x)). In this case, the output (f(x)) is always equal to the input (x) plus one. That is, for any given value of x, the output (f(x)) will be one greater than the input (x). For example, if x is equal to 5, then f(x) would be equal to 6.

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
