1 (part 2). For the following data set: 52, 54, 43, 48, 37, 51, 39, 41, what is the 5 Median?​

Answers

Answer:

45.5

Step-by-step explanation:

First, you need to put the data in order: 37, 39, 41, 43, 48, 51, 52, 54

I'm not sure what 5 median means, but to find the median, you look for the middle number of the data set.

43 + 48 = 91      

then, you divide the numbers by 2 to get the median.

91/2= 45.5

So, the median is 45.5

A cell phone company data about students texting skills.They collected the texting speed in words per minutes according to time in minutes.Identify the data's independent and dependent values

Answers

Answer:

independent variable = Time

Dependent variable = texting speed

Step-by-step explanation:

The Independent and dependent variables are used in regression analysis for making prediction. The Independent variable also called the predictor are the variables or data collected in other to influence or determine the outpjt obtained which is the dependent or predicted variable. Hence, the aim or prediction we wish to obtain, measure or determine is the dependent variable In the scenario above, the aim of the data collected is to determine the typing skill, here, the dependent variable is the typing skill. The data required to define the bthis is the data collected on typing speed which measures time taken to type.

Therefore, independent variable = Time

Dependent variable = texting speed

Profile: John John is a 35 year old, divorced man with one child (who lives with his mom). His take home pay is $4123 per month. He pays $1200 per month in child support to his ex-wife. He owns a 2-storey home and his monthly mortgage payments are $475 every 2 weeks. His car expenses total $145 monthly and his car insurance costs him $113 every month. His house insurance is $47.36 monthly. John also has an outstanding credit line of $8500. The only amount due on this account is the interest of about $55 monthly. However John is trying to pay off the credit line within the next 2 years, so he pays off as much of this loan as he can afford each month.

1.Use one highlighter to identify all sources of income. Total the income for each month.

2.Use a different highlighter to identify all sources of expense. Total the expenses for each month.

3. Subtract the Total Expenses from the Total Income for each

month. A Surplus is when your Income minus Expenses = a positive number.

A Shortage is when your Income minus Expenses = a negative number. Does he have a surplus or a shortage?

Answers

Answer:

1. Income highlight: $4123 of take home pay. That's it.

Total monthly income: $4123

------------------------------------

2. Expense highlight:

$1200 child support

$475 every 2 weeks

$145 car payment

$113 car insurance

$47.36 house insurance

$55 loan payment

Total monthly expense:  $2510.36

(1200 + 2(475) + 145 + 113 + 47.36 + 55 = $2510.36

---------------------------------------------

3. $4123 - 2510.36 = 1612.64 surplus

--------------------------------------------

The only question remaining is what if they want him paying more on his credit line...it's kind of a variable expense at this point.

John also has an outstanding credit line of $8500. The only amount due on this account is the interest of about $55 monthly. However John is trying to pay off the credit line within the next 2 years, so he pays off as much of this loan as he can afford each month.

Helps are really appreciated!!

Answers

Answer:

a) 58.24 square centimeters

b) 5cm

Step-by-step explanation:

a) Area of a parallelogram

The formula for the Area of a parallelogram = Base × Height

Height : 5.2cm

Base : 11.2cm

Area = 5.2 cm × 11.2cm

= 58.24 square centimeters

b) Volume of a cuboid

The formula for the Volume of a cuboid = Length × Width × Height

7cm = Width

3cm = Length

y = Height

Volume = 105cm³

We are to find y

Hence,

105cm³ = 7cm × 3cm × y

y = 105cm³/7cm × 3cm

y = 5cm

Which three lengths could be the lengths
of the sides of a triangle?
A. 4 cm, 8 cm, 13 cm

B. 13 cm, 11 cm, 23 cm

C. 5 cm, 18 cm, 12 cm

D. 25 cm, 8 cm, 16 cm

Answers

Given:

The three lengths in the options.

To find:

Which three lengths could be the lengths of the sides of a triangle?

Solution:

If the sum of two smaller sides is greater than the largest side, then the three sides can form a triangle otherwise the triangle is not possible.

In option A, the three sides are 4 cm, 8 cm, 13 cm. Here, the largest side is 13 cm.

Sum of two smaller sides is:

[tex]4+8=12[/tex]

[tex]4+8<13[/tex]

So, the triangle is not possible.

In option B, the three sides are 13 cm, 11 cm, 23 cm. Here, the largest side is 23 cm.

Sum of two smaller sides is:

[tex]13+11=24[/tex]

[tex]13+11>23[/tex]

So, the triangle is possible.

In option C, the three sides are 5 cm, 18 cm, 12 cm. Here, the largest side is 18 cm.

Sum of two smaller sides is:

[tex]5+12=17[/tex]

[tex]5+12<18[/tex]

So, the triangle is not possible.

In option D, the three sides are 25 cm, 8 cm, 16 cm. Here, the largest side is 25 cm.

Sum of two smaller sides is:

[tex]8+16=24[/tex]

[tex]8+16<25[/tex]

So, the triangle is not possible.

Therefore, the correct option is B. The three lengths 13 cm, 11 cm, 23 cm could be the lengths of the sides of a triangle.

Answers

Answer:

The two lines are neither parallel nor perpendicular

Step-by-step explanation:

Generally, we have the equation of a straight line as;

y = mx + b

where m is the slope of the line and b is the y intercept of the line

Now, we express the two given equations in this form

We have this as;

7y = x + 5

y = 1/7(x) + 5/7

For the second equation, we have;

y = 7x - 4; this is already expressed

the slope of the first line is 1/7

the slope of the second line is 7

when two lines are parallel, their slopes are equal

when two lines are perpendicular, the product of their slopes is -1

As we can see, both cases does not occur in this system of equations

So, we can conclude that both lines are neither parallel nor perpendicular

Their is a rectangle that has measurements in inches. If the width is 7/8 of an inch and the height is 2/3 of an inch, what is the AREA of the rectangle?

Answers

Answer:

Area of a rectangle = 7/12 of an inch

Step-by-step explanation

Area of a rectangle = Length × width

In this case, the length is represented by height

Height = 2/3 of an inch

Width = 7/8 of an inch

Area of a rectangle = Length × width

= 2/3 × 7/8

= (2 * 7) / (3 * 8)

= 14 / 24

= 7 / 12

Area of a rectangle = 7/12 of an inch
