Please help with this math question!

The given sample of the randomly selected players from the teams as described is a stratified sample. Hence, the right answer is option A.

In a stratified sample, the population is divided into groups (or strata) based on some characteristic, and a random sample is selected from each group. In this case, the population is the football players, and the groups are the varsity and junior varsity teams. The coach randomly selects one of these teams and then asks all players from that team their opinion on a new logo.

This type of sampling is used when the population is divided into subgroups that are different in some way, and the researcher wants to ensure that these subgroups are represented in the sample. In this case, the coach wants to ensure that both varsity and junior varsity players are represented in the sample, as they may have different opinions on the new logo.

It's not a simple random sample because he selected the team first and then the players. Also, it's not a voluntary response sample because the coach is selecting the players.

It's not a cluster sample because the coach is not selecting the players based on location or geographic proximity, and it's not a systematic sample because he is not selecting the players based on the order in which they appear in a list or a database.

Answer:

\(w^{22}\)

Step-by-step explanation:

\((w^3)^4\cdot(w^5)^2=w^{3*4}\cdot w^{5*2}=w^{12}\cdot w^{10}=w^{12+10}=w^{22}\)

Answer:

The answer is true!

Step-by-step explanation:

Since B is in the middle and they both are congruent.

y= -5/4x + 11/2

1) Since we have point (2,3) and it is perpendicular to points (0, 0) and (5,4)

Let's find out the slope between (0, 0) and (5,4)

2) As it is perpendicular, then the slope is reciprocal and opposite to 4/5, so that slope is going to be -5/4

Let's plug point (2,3) , as point (2,3) belongs to that line, into the slope-intercept formula:

(2,3)

y=mx +b

3 =2 (-5/4) +b

3 =-5/2 +b

3+5/2 = b

b=11/2 Linear coefficient

3) So finally, we can write the equation of that line as y=-5/4x + 11/2

Answer:

y=\(\frac{7}{10}x+\frac{7}{2}\)

Step-by-step explanation:

Hi there!

We want to find the equation of the line containing the points (5/7,4) and (-5/7, 3)

The most common way to write an equation of the line is slope-intercept form, which is given as y=mx+b where m is the slope and b is the y intercept

So first, let's find the slope of the line

The formula for the slope calculated from two points is \(\frac{y_2-y_1}{x_2-x_1}\) where (\(x_1\),\(y_1\)) and (\(x_2\),\(y_2\)) are points

We have everything needed to find the slope, but let's label the values of the points to avoid any confusion

\(x_1\)=5/7

\(y_1\)=4

\(x_2\)=-5/7

\(y_2\)=3

Now substitute into the formula

m=\(\frac{y_2-y_1}{x_2-x_1}\)

m=\(\frac{3-4}{\frac{-5}{7}-\frac{5}{7}}\)

Subtract and simplify

m=\(\frac{-1}{\frac{-10}{7}}\)

m=-1*\(\frac{7}{-10}\)

m=\(\frac{-7}{-10}\)

m=\(\frac{7}{10}\)

So the slope of the line is \(\frac{7}{10}\)

Here is the equation of the line so far:

y=\(\frac{7}{10}x\)+b

We need to find b

As the equation of the line passes through both (5/7, 4) and (-5/7, 3), we can use either one of them to solve for b

Let's take (5/7, 4) for this case

Substitute x as 5/7 and y as 4

4=\(\frac{7}{10}\)*\(\frac{5}{7}\)+b

Multiply and simplify the fractions

4=\(\frac{1}{2}\)+b

subtract 1/2 from both sides

\(\frac{7}{2}\)=b

So the equation of the line is y=\(\frac{7}{10}x\)+\(\frac{7}{2}\)

Hope this helps!

Step-by-step explanation:

Answer:

36 green marbles

Step-by-step explanation:

If 60% of the 60 marbles in the bag are green, then the number of green marbles can be calculated as:

Green marbles = 60% x 60 marbles

To simplify this calculation, we can convert 60% to a decimal by dividing by 100:

Green marbles = 0.60 x 60 marbles

Green marbles = 36 marbles

Therefore, Rudy received 36 green marbles.

Answer: 36

Step-by-step explanation:

60 is 6/10 of 100 so if you are taking a percent of 60 just multiply the percentage by 6/10. 6/10 of 60 is 36

The value of x in the triangle will be 19.7°.

We are given the sides of the triangle as:

5, 7 and 11 units

We need to find the measure of angle x

Answer:

The answer is -3x + 3

The correct answer is option C: \(\(k + 4 = 16\).\) This linear equation represents the relationship between Tina and Kai's volunteer times.

To represent the given situation, the equation that correctly represents the relationship between Tina's volunteer times (Tina = 16) and Kai's volunteer times (Kai = k) is:

\(\[Tina = Kai + 4\]\)

In this equation, Tina's volunteer times are represented by "Tina," and Kai's volunteer times are represented by "Kai." Since Tina has volunteered 4 more times than Kai, we add 4 to Kai's volunteer times to get the total number of times Tina has volunteered.

Substituting the given values, we have:

\(\[16 = k + 4\]\)

This equation represents the fact that Tina has volunteered \(16\) times, which is equal to Kai's volunteer times (k) plus the additional 4 times that Tina volunteered.

Simplifying the equation:

\(\[k + 4 = 16\]\)

This equation is equivalent to the original equation and represents the relationship between Tina and Kai's volunteer times. Hence, the correct answer is option C: \(\(k + 4 = 16\).\)

Step-by-step explanation:

271 unit² is the  area of the polygon. The correct option is option B among all the given options.

The size of a patch on a surface is determined by its area. Surface area is defined as the circumference of an open surface or indeed the boundaries of a three-dimensional object, whereas the area of a plane region and plane area relates to the area of a form or planar lamina.

Area can be interpreted as the quantity of material with such a specific thickness required to create a replica of the shape or as the quantity of paint required to completely cover a surface in a single coat. This is the two-dimensional equivalent of the volume of a solid or the length of a curve.

The area is the sum of 3 rectangles are:

First          12 × 19 = 228

The guests in the birthday party ate 33 cookies.

We know that Mrs. Smith made 6 1/4 dozen cookies and there were 3 1/2 dozen cookies left.

Let's first convert these fractions to a common denominator of 4, so we can easily subtract them.

6 1/4 dozen = 25/4 dozen

3 1/2 dozen = 14/4 dozen

Now we can subtract the number of cookies that were left from the number of cookies that were made:

25/4 - 14/4 = 11/4 dozen

To find out how many cookies this represents, we need to multiply by the number of cookies in one dozen.

There are 12 cookies in one dozen, so:

11/4 x 12 = 33

Therefore, the guests ate 33 cookies.

Answer:

a) \(10x+8y \geq 200\)

b) The members should sell at least 15 puzzles

Step-by-step explanation:

Let x represents selling games

and y represents puzzles

The statement given is: They make a profit of $10 per game and $8 per puzzle. They would like to make a profit of at least $200.

a) The inequality will be:

\(10x+8y \geq 200\)

at least 200 means the profit can be equal to 200 or greater than that.

b) If the members sell 8 games, how many puzzles would they have to sell?

Number of puzzles sold can be solved by solving the inequality \(10x+8y \geq 200\)

Put x =8 and find value of y

\(10x+8y \geq 200\\10(8)+8y\geq 200\\80+8y\geq 200\\8y\geq 200-80\\8y\geq 120\\y\geq \frac{120}{8}\\y\geq 15\)

So, the members should sell at least 15 puzzles to make the inequality true. because the profit should be at least $200.

Answer:

\(2.5\% = \frac{2.5}{100} \\ \\ = \frac{25}{1000} \)

divide numerator and denominator by 25:

\( = \frac{25 \div 25}{1000 \div 25} \\ \\ ={ \boxed{ \boxed{ \frac{1}{40} }}}\)
