Answer:

5 students out of each of the 4 homeroom classes

Step-by-step explanation:

The most random sample is 5 students out of each of the 4 homeroom classes.

Thus, option (C) is correct.

Selecting 5 students from each of the 4 homeroom classes ensures that the sample represents a diverse range of students from different classes.

This approach helps to minimize bias and increase the randomness of the sample.

The other options, such as selecting the first 20 students who arrive at school or the last 20 people in line for breakfast, may introduce some bias based on the specific circumstances or characteristics of those groups. Selecting all 20 boys on the swim team would also not provide a representative sample of the overall student population.

Thus, option (C) is correct.

Step-by-step explanation:

The required multiplier for 21.6% decay is 78.4%.

Given that,
To find the multiplier for 21.6% decay

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

The process in mathematics to operate and interpret the function to make the function simple or more understandable called simplifying and the process is called simplification.

In the question, the multiplier for the rate of 21.6% decay is to be determined.
A multiplier of decay implies decay  = 1 - r

Since let the Decay multiplier be x
x = 1 - r
x = 1 - 0.216
x = 0.784
x = 78.4%

Thus, the required multiplier for 21.6% decay is 78.4%.

Answer:

840

Step-by-step explanation:

First you have to multiply 42 by 20. Because you have to find the total cost of the whole bag. Then a little guess and check you would get 16 lb of green tea and 4 lb of herbal tea. They both have to equal 20 lbs and $840. Multiply 16 by 40 then 50 by 4 then add them together you will get 840.

Answer:

[tex]a = \{1,4,9,16,25,36,49,64,81,100\}[/tex]

Step-by-step explanation:

Given

[tex]ax^2 - 64[/tex]

Required

Determine possible values of a

For the expression to be a difference of two squares, then a must be a perfect square between 1 and 100 (inclusive).

Let [tex]a = k^2[/tex] where [tex]k \ge 1[/tex]

When k = 1

[tex]a = 1^2 = 1[/tex]

k = 2

[tex]a = 2^2 = 4[/tex]

k=3

[tex]a = 3^2 = 9[/tex]

It goes on until k = 10

[tex]a = 10^2 = 100[/tex]

So, the possible values of a are:

[tex]a = \{1,4,9,16,25,36,49,64,81,100\}[/tex]

Answer: Slope=-2/3

Step-by-step explanation:

The four numbers whose sum equals 0, none of which are opposites are

-2,  4, -9, 7.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Four numbers:

-2,  4, -9, 7

We see that,

The sum of the four numbers is 0.

-2 + 4 + (-9) + 7

= -11 + 11

= 0

None of the numbers are opposite.

Thus,

The four numbers are -2, 4, -9, and 7.

[tex]\frac{\pi}{6}[/tex] radian

Step-by-step explanation:

We are given that an angle in degrees

[tex]\theta=30^{\circ}[/tex]

We have to find the angle in radian measure as a multiple of π

To find the value of 30 degree in radian we will use the radian measure formula

We know that

Radian measure=[tex]\frac{\pi}{180}\times degree\;measure[/tex]

Using the formula

Radian measure of 30 degree=[tex]\frac{\pi}{180}\times 30[/tex]

Radian measure of 30 degree=[tex]\frac{\pi}{6}[/tex] radian

Hence, the radian measure of 30 degree is given by

[tex]\frac{\pi}{6}[/tex] radian

Answer:

so um try The y-intercept represents a starting salary of $ 3,000 for a new employee.

The slope represents an additional $ 2,500 in salary for each additional year of employment.

If the starting salary for a new employee is changed to $35,000 and the salary increase is unchanged, the new equation would be y= 2,500x + 35,000

If the yearly salary increase is changed to $ 2,500 . the new equation would be y= 3,000
