Answer:um what are the options

Step-by-step explanation:

Answer: Between each quartile is 25% of the data

The percentage of the data values that are greater than 65, as shown in the box plot is: 25%.

A box plot shows how the data points of a data set are distributed, in such a way that, 25% of the data points lie below the lower quartile, 50% lie below the median, and 75% lie below the upper quartile.

In the box plot given, the values that are greater than 65 lie above the upper quartile, which equals about 25% of the data values.

Therefore, the percentage of the data values that are greater than 65, as shown in the box plot is: 25%.

well, it was truly 12.5 mL, however she said 13 mL, well, she was off by 13 - 12.5 = 0.5 mL.

Now, if we take 12.5(origin amount) to be the 100%, what is 0.5 off of it in percentage?

\(\begin{array}{ccll} Amount&\%\\ \cline{1-2} 12.5 & 100\\ 0.5& x \end{array} \implies \cfrac{12.5}{0.5}~~=~~\cfrac{100}{x} \implies 12.5x=50 \\\\\\ x=\cfrac{50}{12.5}\implies x=\stackrel{\%}{4}\)

Answer:

The two other angles are 29 degrees and 61 degrees

Step-by-step explanation:

There are 180 degrees in a triangle. Given this is a right triangle one of the angles is 90 degrees. As in the other two angles have to equal up to 90 degrees. Now we have to find x.

180 - 90 = 90

If x equals 28

28 + 1 = 29

2 x 28 + 5 = 61

29 + 61 = 90

The two other angles are 29 degrees and 61 degrees

Answer:

29 , 61

Step-by-step explanation:

Sum of all angles of a triangle = 180

90 + x + 1 +2x +5 = 180 {Combine like terms}

96 + 3x = 180         {Subtract 96 from both sides}

         3x = 180 - 96

          3x = 84 {Divide both sides by 3}

           x = 84/3

x = 28

x +1 = 28 +1 = 29

2x +5 = 2*28 + 5 = 56 + 5 = 61

Answer:

10 3/4

Step-by-step explanation:

\(x + \frac{7}{4} = - \frac{5}{2} \times - \frac{5}{1} \\ x = \frac{25}{2} - \frac{7}{4} \\ x = \frac{43}{4} \\ x = 10 + \frac{3}{4} \)

Answer:

y = 42

Step-by-step explanation:

5/7=30/y

Cross multiply.

5y = 7 × 30

5y = 210

Divide 5 into both sides.

y = 210/5

y = 42

Answer:

y = 42

Step-by-step explanation:

5/7=30/y

Use cross products

5y = 7*30

5y = 210

Divide by 5

5y/5 = 210/5

y =42

Answer:

Step-by-step explanation:

Hi, to answer this question we have to write an equation:

The food bill (x) plus the tip (16) ;divided by the number of friends (8) , must be equal to the total amount spent (76) divided by the number of friends (8):

Mathematically speaking:

(x+16) /8 = 76/8

(x+16) /8 = 9.5

(x+16) = 9.5 (8)

x+16 = 76

x = 76-16  

x= 60 (food bill)

So, the correct options are:

(1/8 (x+16) =76/8)

Answer:

A & C is your answer.

Step-by-step explanation:

1. Angles are complementary which means they add up to 90°

3x + 6 + 2x - 11 = 90° (angles are complementary)

5x - 5 = 90

5x = 90 + 5

5x = 95

x= 95/5

x= 19

Therefore

m∠G = 3x+6

= 3(19)+6

= 63°

m∠H= 2x-11

= 2(19)-11

= 27°

2. Angles are supplementary which means they add up to 180°

m∠J + 29 = 180°

m∠J= 180-29

m∠J =151°

As c increases,the value of x -

1. Increase

2. decrease

3. stays same

4. increase

Proportionality indicates that two quantities or variables are related in a linear manner. If one quantity increases, so does the other and vice versa.

Now in the given question we have the following equations :

1. x-c = 0

2. cx = 1

3. cx = c

4. x/c = 1

1. x-c= 0

⇒ x = c

Hence, in this case if the value of c increases, so does the x will increase.

2. cx = 1

⇒ c= 1/x

Hence, in this case if the value of c increases, so does the x will decrease.

3. cx = c

⇒ x = 1

Hence, in this case if the value of c increases, the value of x remains the same.

4. x/c = 1

⇒ x = c

Hence, in this case if the value of c increases, so does the x will increase.

Hence, we conclude that As c increases,the value of x

1. As c increases,the value of x Increases.

2. As c increases,the value of x decreases.

3. As c increases,the value of x stays same.

4. As c increases,the value of x increases.

Step-by-step explanation:

the answer is A) 63\(\frac{351}{441}\)

Answer:

63 Remainder 351

Step-by-step explanation:

For small division problems, the quotient and remainder can easily be thought of. But for larger division problems, long division is one technique that will work for any division problem, no matter how small or large it is.

Let's take a look at how long division works with the simple division problem of 7 / 3 first.

Setting up the problem, it looks like this with the 7 inside the division bracket and the 3 outside.

THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!

The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.

The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.

Answer:(-5,1) (-5,2) (-8,1)

Step-by-step explanation: first, the x reflects on the same distance away from the y-axis but the x points are negative, to make go from (5,1) to (-5,1) which puts on the y side.

Answer:

mRJN = 75°

Step-by-step explanation:

VJA = 15°

If the line VJ would continue through J and stop at a point that we now call Z. Then the new angle ZJN which is a vertically opposite angle to VJA would also be 15°

Angle VJE is supplementary to VJR and therefore also 90°

And if angle VJE is 90°, that means its supplementary angle EJZ is also 90°.

Angle EJN (supplementary to RJN) is simply EJZ - ZJN = 90° - 15° = 75°

To design a spinner with the given probabilities, we can use the following sectors:

A sector covering 60 degrees for the number 1, with probability 1/6.

A sector covering 120 degrees for the number 3, with probability 1/3.

A sector covering 180 degrees for the number 7, with probability 1/2.

A sector covering 180 degrees for the odd numbers (1 and 3), with probability 1.

To create the spinner, draw a circle and divide it into four equal sectors. Color one sector red for the number 1, color two adjacent sectors green for the number 3, color one remaining sector blue for the number 7. Finally, color half of the blue sector green to represent the odd numbers.

The resulting spinner will have the desired probabilities: P(1) = 1/6, P(3) = 1/3, P(7) = 1/2, P(odd number) = 1.

No, since there are two inputs (time in hours) which have the same cost (in dollars). Therefore, option A is the correct answer.

Explanation:

What is the function?

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

From the given that,

(1, 25), (2, 45), (3, 45) and (4, 55)

It is not a function as two inputs 2 and 3 has a single output 45.
