Answer:

so u take 4/12 and do it to 1/3 then try to do lest to greatest

Step-by-step expla

2/3 5/6 1/2 1/3 try

So the fractions will be 2/3, 1/2, 4/12, and 5/6. 4/12 would be the least because when simplified, it is 1/3. Then would be 1/2 followed by 2/3 because 2/3 is more than a half. And the greatest would be 5/6 because if all the fractions had a common denominator of 3 the 5/6 would have the greatest numerator (2.5)

Haven't done this kinda problem in a while but I got 4/3 cm/s

Step-by-step explanation:

Using the coordinates given i put them into the formula:

        y1  -  y2

m=_________

        x1  -  x2

That gave me -16/-12, I simplified & got 4/3.

unit rate in this case would be the slope
To find the slope you need at least two points on a line
The formula would be m=y2-y1/x2-x1

16-0/12-0
16/12
Simplified we would divide by 4 since it goes into both numbers
4/3 as the answer

The statement that is false on Jose drawing cards from the deck is B. For a given number of selections, we can use Joseph's graph to find the number of diamonds that he has picked so far.

What is probability?

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

here, we have,

given that,

Jose draws a card from a deck replaces it and draws again he records a number of times he draws an ace. He decides to record the total number of aces that he selects and calculates the proportion of aces that he has selected so far after each pick. He then constructs a graph to visualize his results.

as the graph can not be used:

Jose only recorded the number of aces he selected, not the number of diamonds. Therefore, we cannot use his graph to find the number of diamonds he picked.

However, if we were to use the graph to find the number of aces that Jose has picked so far, then we would be successful. The other statements are true as Jose recorded the cards he took and the cards were replaced after each pick.

The circle graph describes the distribution of preferred music from a sample of 400 randomly selected middle school students.

a circle graph titled preferred music, with five sections labeled rock 13 percent, hip hop 25 percent, pop 35 percent, classical 13 percent, and jazz 14 percent

Which of the following conclusions can we draw from the circle graph?

Pop is the preferred music for 35 students.
Jazz is the preferred music for 56 students.
Together, Hip Hop, Rock, and Jazz are the preferred music for less than half the students.
Together, Hip Hop and Pop are the preferred music for 260 students.

Answers

Answer:

Step-by-step explanation:

(i) Number of people who are into classical music =10%

10% of pie chart =20 people.

1% ⇒ 10/20 ×100

and 100% ⇒ 10/20 ×100 × 100/ 100

​⇒200 people.

(ii) Light chart represent maximum number as it is 40% of total. ∴ Light music is liked by maximum people.

(iii)

Number of CD's of classical music ⇒ 100/10 × 1000(10%) =100

umber of CD's of semi classical music = 100/20 × 1000(20%) =200

just like that 30% is 300, 40% is 400.

Hope this helped :)

Solve the equation using inverse operations. Check your solutions. In your final answer, include all of your work.
1÷4 x³ = –27÷4

Answers

1. First, divide both sides of the equation by 4.

1÷4 x³/4 = –27/4/4

2. Next, on the left side of the equation, use inverse operations to get rid of the division. This will give us x³ = –27.

3. Then, to solve for x, take the cube root of both sides of the equation.

Cube root of x³ = cube root of –27

4. To check your answer, plug in -3 for x in the original equation and solve.

1÷4 x³ = –27/4

1÷4 (-3)³ = –27/4

1÷4 (-27) = –27/4

1 = 1

Since 1 = 1, the answer checks out.

Therefore, the solution to the equation is x = -3.

The expression 9.00x+4.50y represents the total amount of money Harriet earns at her two jobs, where x represents the number of hours worked at job X and y represents the number of hours worked at job Y. Which shows an equivalent expression to the given expression and correctly describes the situation?

4.50(2x+y), which shows that Harriet earns twice as much per hour at job X than job Y.

4.50(2x+y), which shows that Harriet earns 4.50 times as much per hour at job X than job Y.

Answers

The equivalent expression that correctly describes the situation is:

13.50xy, which shows that Harriet earns $13.50 for each hour she works.

This expression represents the total amount of money Harriet earns at both jobs, where x represents the number of hours worked at job X and y represents the number of hours worked at job Y. The coefficient of xy, which is 13.50, represents the amount of money Harriet earns per hour, regardless of which job she is working. Therefore, this expression accurately reflects the situation described

a sample of 500 schools in a state results in an average number of students per grade level of 178.6 students, with a margin of error of 45.2 if there are 3250 high schools in the state, what is the estimated number of students per grade level?​

Answers

To estimate the number of students per grade level in the state, we can use the sample average and the margin of error to construct a confidence interval.

The margin of error is given as 45.2, which means that we can be 95% confident that the true population average number of students per grade level falls within the range of the sample average plus or minus the margin of error.

So, the confidence interval is:

178.6 ± 45.2

To estimate the population average number of students per grade level, we can take the midpoint of the confidence interval:

(178.6 + (178.6 - 45.2)) / 2 = 311.6

Therefore, the estimated number of students per grade level in the state is 311.6

Triangle ABC is a scale drawing of Triangle XYZ, as shown.
Based on the information shown in these triangles, which of the following is a true statement?

A) The length of side XZ is 11.5.
B) The length of side XZ is 28.
C) The measure of angle A is equal to the measure of angle Z.
D) The measure of angle A is not equal to any of the angle measures of Triangle XYZ.

Answers

Answer: B the side length of XZ is 28

Step-by-step explanation:

to find the scale factor, one of the methods is to divide the side length of one triangle by the same side length of the other triangle.

for example with this problem, the length of XY is 42 while side length AB is 12. 42/12 is 3.5. we know that the side length that corresponds with XZ is 8 so multiply it by 3.5 to get the answer of 28.

Answer:

B

Step-by-step explanation:

Since we know that triangle XYZ is a scale model of ABC then if we find the amount XYZ is bigger then ABC then we can find the answer. Line CB is the corresponding line to ZY and ZY is 3.5x greater then CB. Apply the same logic to AC and we get 8*3.5=ZX 8*3.5=28 so ZX=28.

Drag each expression to show whether it is equivalent to 36x+9
or 9(4x−1)
.

Answers


In order to find out what 36x + 9 is equivalent to,, we must factor out 9 from the expression. Once we do this you will find that this expression is equivalent to 9(4x + 1),, or option E.
Next we will look at the expression 9(4x-1). In order for us to find out the equivalent to this expression,, we must first multiply each term in the parenthesis by 9.
9 × 4x - 9
Now calculate the product
36x - 9
This means that the equivalent for this expression is
36x - 9,, or option A.
Lastly,, we will look at the final expression given which is 4(9x + 2). The first step for finding the equivalent of this expression is to multiply the numbers in the first parenthesis together.
(36x) + (4 × 2)
Now multiply the numbers in the second parenthesis together.
(36x) + 8
Remove the parenthesis
36x + 8
Now factor out 4 from the expression to get your final answer.
4(9x + 2)
This means that the last expression is equivalent to 4(9x + 2),, or option C.
Let me know if you have any further questions
C because the last expression is equivalent to 9(4x-1).

-2 1/3 ÷ 4 2/3
Please help, I will grant the 1st person to answer correctly brainliest.

Answers

Answer: -1/2

Step-by-step explanation:

1. We know that -2 1/3 is also equal to -7/3, because we can multiply the denominator by the main number, and add the numerator.

2. We can do the same with 4 2/3, which would be 14/3.

3. Now, we are left with -7/3 divided by 14/3.

4. To make this easier, we can flip flop the 14/3 so we can multiply instead of divide, which leaves us with -7/3 x 3/14.

5. -7/3 x 3/14 = -21/42

6. We can simplify this to -1/2.
