what is the value of y when: -5=y-7over 9

Answer: Answer:Median: 10.5Lower quartile: 4Upper quartile: 16Explanation:Median:First, write the observations in ascending order or descending order.The formula to calculate the median is mean of (n/2) and (n/2+1)th observations, for even number of observationsn = 12 (even)Median = Mean of (6)th and (7)th observations = 10 + 11 divided by 2 = 21/2 = 10.5Therefore the median is 10.5.After writing in ascending or descending order the first and last terms justify the lower and upper limits respectively.They are:Lower quartile: 4Upper quartile: 16Question 2.the lengths of 10 pencils, in centimeters:18, 15, 4, 9, 14, 17, 16, 6, 8, 10Type below:_________________Answer:Median: 12Lower quartile: 4Upper quartile: 18Explanation:Median:First, write the observations in ascending order or descending order.The formula to calculate the median is mean of (n/2) and (n/2+1)th observations, for even number of observationsn = 10 (even)Median = Mean of (5)th and (6)th observations = 10 + 14 divided by 2 = 24/2 = 12Therefore the median is 12.After writing in ascending or descending order the first and last terms justify the lower and upper limits respectively.They are:Lower quartile: 4Upper quartile: 18Question 3.Make a box plot to display the data set in Exercise 2.Type below:_________________Answer:The above box plot represents the lower and upper quartiles, the median.Explanation:Box plot is drawn using the number line and the rectangle which is drawn above it.The ends of the rectangles say about the lower and upper limits and the middle line indicates the median.Question 4.The numbers of students on several teams are 9, 4, 5, 10, 11, 9, 8, and 6. Make a box plot for the data.Type below:_________________Answer: Explanation:Box plot is drawn using the number line and the rectangle which is drawn above it.The ends of the rectangles say about the lower and upper limits and the middle line indicates the median.Therefore the lower and upper quartiles are 4 and 11 respectively.Median:First, write the observations in ascending order or descending order.The formula to calculate the median is mean of (n/2) and (n/2+1)th observations, for even number of observationsn = 8 (even)Median = Mean of (4)th and (5)th observations = 8 + 9 divided by 2 = 17/2 = 8.5Therefore the median is 8.5.

Step-by-step explanation:

Answer: The slope is positive, which tells us that the line has an upward direction.

Step-by-step explanation:

The slope of a line is calculated by finding the difference of the y-coordinates and dividing it by the difference of the x-coordinates.

In this case, the difference of the y-coordinates is -2 - (-14) = 12, and the difference of the x-coordinates is -7 - (-15) = 8.

The slope is therefore 12/8 = 1.5.

Answer:

105

Step-by-step explanation:

Area of a trapezoid is given by the formula:

A = (a+b)÷2×h

(where h is the vertical height, and a and b are the parallel lines)

Substituting values given gives us:

A = (6+15)÷2×10

A = 21÷2×10

A = 10.5×10

A = 105

∠CDJ = 34°.

Step-by-step explanation:

In this question AK and MJ intersect at 90°.

∠ADC = 4x° and ∠JDC = (3x - 8)°

We have to find the measurement of ∠CDJ.

Since ∠MDA = ∠KDJ = ∠ADJ = ∠MDK = 90°

Therefore ∠ADJ = ∠ADC + ∠JDC = 90°

4x + 3x - 8 = 90

7x - 8 = 90

7x = 98

x = 98/7 = 14

Therefore m∠CDJ = 3x - 8 = 3×14 - 8 = 42 - 8 = 34°

Answer is m∠CDJ = 34°

Answer:A fraction represents a part of a whole

Step-by-step explanation:

eg: 3/5 by 5/5

please view explanation

The definition of a fraction is a part of a whole .

If a whole is  divided into equal parts, these equal parts are called fractions.

Fractions are written like this :

[tex]\boxed{\\\begin{minipage}{4cm}fractions\\$\displaystyle\frac{x\xrightarrow{numerator}}{y\xrightarrow{denominator}} \\ \end{minipage}}[/tex]

 Where

y = the number of total parts

x = the number of parts taken

Now, it doesn't necessarily have to be a pizza or a cake.

Suppose your companion Danette has 32 pencils. Out of them, 8 pencils are red.

What fraction of the pencils is red?

Total number of pencils = 32 (denominator)

Number of red pencils = 8 (numerator)

So the fraction of red pencils is :

[tex]\boxed{\\\begin{minipage}{4cm}Danette's\:pencils \\ $\displaystyle\frac{8}{32} \\ \end{minipage}}[/tex]

If the numerator and denominator are divisible by the same number, then we can reduce the fraction :

[tex]\boxed{\\\begin{minipage}{4cm}Danette's\:pencils \\ $\displaystyle\frac{1}{4} $\\ \end{minipage}}[/tex]

Step-by-step explanation:

Answer:

$45.48

Step-by-step explanation:

Given that:

Gas tank are 11 inches, 1.25 feet and 1.75 feet.

The gas tank is 20% full. Use the current price of gas in your community to find the cost to fill the tank (1 gal = 231 in³)

Current price = 3.79

Solution:

Formula: Volume = LWH

While,

L = Length

W = Width

H = Height

Since we, know that

Gas tank are 11 inches, 1.25 feet and 1.75 feet.

We have to convert either to inches or feet.

Note that: 1 feet = 12 inches

I will convert feet to inches

Thus,

1.25 × 12 = 15

1.75 × 12 = 21

Since 11 is already in inches we don't have to change that.

Now from the formula: LWH

Therefore, we have:

V = 11 × 15 × 21

V = 3465

Now, from the given the gas tank is 20% full

Finding 20%:

3465 × 20 % = 693

Now subtract to find the other 80%

3465 - 693 = 2772

Since 1 gal = 231 in ³

2772/ 231 = 12

Now, 12 mulitply by the current price of gas given:

12 × 3.79 = 45.48

Hence, the cost to fill the tank is $45.48

Answer:

$45.48

Step-by-step explanation:

Convert to inches

1.25 × 12 = 15

1.75 × 12 = 21

Since 11 is already in inches we don't have to change that.

Now from the formula: LWH

Therefore, we have:

V = 11 × 15 × 21

V = 3465

Now, from the given the gas tank is 20% full

Finding 20%:

3465 × 20 % = 693

Now subtract to find the other 80%

3465 - 693 = 2772

Since 1 gal = 231 in ³

2772/ 231 = 12

Now, 12 mulitply by the current price of gas given:

12 × 3.79 = 45.48

Hence, the cost to fill the tank is $45.48

Answer:

13

Step-by-step explanation:

To find the interquartile range you would first have to find the median. If you list the number in least to greatest order you will find that the median is 30.5. After you find the median you will spilt the data set up. So on one side it will be 20, 25, 30 and 30, the other side you be 31, 40, 41, and 49. Next, you would find the median of the first set that I listed which is 27.5. You would do the same for the second set and find the median which is 40.5. You would then subtract the first sets median from the second sets median which is 40.5-27.5 and that is 13.
