Answers

Answer:median of (298, 196, 248) - 196

median of (379, 319) - 349

median of (276,198, 349) - 198

Step-by-step explanation:

Answer:

298

Step-by-step explanation:

Given:

$298,$196, $248, $379, $319, $276, $198, $349, $319

Solve:

Put in order:

196, 198, 248, 276, 298, 319, 319, 349, 379

Median -

Arrange data values from lowest to highest value

The median is the data value in the middle of the set

If there are 2 data values in the middle the median is the mean of those 2 values.

Solution:

196, 198, 248, 276, 298, 319, 319, 349, 379

196, 198, 248, 276, 298, 319, 319, 349, 379

196, 198, 248, 276, 298, 319, 319, 349, 379

196, 198, 248, 276, 298, 319, 319, 349, 379

 Hence, the median is 298.

Identify the correct weight to the nearest 1/8 pound, then reduce the fraction if possible.

A. 2 12/16 = 2 3/4 Ib
B. 2 2/8 = 2 1/4 Ib
C. 2 14/16 = 2 7/8 Ib
D. 2 1/2 Ib

Answers

The measured weight is (2 + 3/4) lb, so the correct option is A.

How to read the measure?

First, we can see that the needle is between the 2lb and 3lb mark, so we know that we have a measure between these two values.

Now, let's count the number of small lines between the needle and the 2lb mark. There are 12 marks (the 12th is below the needle). Then the measure will be:

(2 + 12/16) lb.

Now we want to simplify the fraction. If we divide both numerator and denominator by 4, we get:

12/16 = 3/4

Then the weight is:

(2 + 3/4) lb

Then the correct option is A.

How to Convert Feet to Inches
To convert a foot measurement to an inch measurement, multiply the length by the conversion ratio.

Since one foot is equal to 12 inches, you can use this simple formula to convert:

inches = feet × 12
The length in inches is equal to the feet multiplied by 12.

Which of the following would describe Slope?
A Rise/Run


B The rate of change


C The steepness of a line


D All of the above

Answers

I guess A because rise/run is one graph and that’s how you plug the slope on the graph

Answer:

Rise/Run (A)

Step-by-step explanation:

The slope of a line measures the steepness of the line. Most of you are probably familiar with associating slope with "rise over run". Rise means how many units you move up or down from point to point. On the graph that would be a change in the y values. Run means how far left or right you move from point to point.

Answers

The unknown angles in the cyclic quadrilateral is as follows:

∠BGX = 74° (sum of angles in a triangle)

∠BGF = 180° (opposite angles of cyclic quadrilateral are supplementary)

∠BCF = 100°(sum of angles in a triangle)

∠BCG  = 26°

∠BFG = 22°

Cyclic Quadrilateral

A cyclic quadrilateral has all its angles equal to 360 degrees. The sum of angles in a cyclic quadrilateral is equals to 360 degrees.

Let's find the missing angles as follows:

∠BGX = 180 - 48 - 58 = 74° (sum of angles in a triangle)

∠BGF = 180 - 100 = 80° (opposite angles of cyclic quadrilateral are supplementary)

∠BCF = 180 - 22 - 58 = 100°(sum of angles in a triangle)

∠BCG = 100 - 74 = 26°

Suppose if, instead of depositing the $600 all at once, you deposit nothing at the beginning and you divide up the $600 into 12 envelopes each with $50. Find the balance after one year if you deposit one $50 envelope each month, all year, into an account that pays 5% APR with monthly compounding.

Answers

The balance after one year if you deposit one $50 envelope each month, all year is  $613.95.

What is the balance after one year?

The balance after 1 year can be determined using this formula:

Amount deposited monthly x annuity factor

Annuity factor = {[(1+r)^n] - 1} / r

Where:

r = interest rate = 5% /12 = 0.417%n = number of years = 1 x 12 = 12

Annuity factor = 1.004167^12 - 1 / 0.00417 = 12.279082

Balance = 12.279082 x 50 = $613.95

how do you find the square root for 9cm ​

Answers

Square Root of 9:-

[tex]\rightarrow[/tex]Square root of 9 is a whole number that is multiplied by itself to get the original number. The actual value of square root of 9 is 3.

√9 = ±3

[tex]\rightarrow[/tex]If we square +3 or -3, the resulting value will be equal to 9.

[tex]\sf{(+3)^2 = 9}[/tex]

[tex]\sf{(-3)^2 = 9}[/tex]

How to find?:-

[tex]\rightarrow[/tex]Number 9 is an odd number and not a prime number. Prime numbers have only two factors, 1 and the number itself. But as we know, 9 have three multiple factors, 1, 3 and 9 itself. Thus, we can write the number 9 in the form of multiple as;

[tex]\sf{1 × 9 = 9}[/tex][tex]\sf{3 × 3 = 9}[/tex][tex]\sf{9 × 1 = 9}[/tex]

[tex]\rightarrow[/tex]You know that number 9 is a multiple of 3 or when 3 is multiplied by itself, we get the number 9. Therefore, we can write the square root of 9 as;

➾[tex]\sf{\sqrt{9}}[/tex]

➾[tex]\sf{\sqrt{3×3}}[/tex]

➾[tex]\sf{\sqrt{3^2}}[/tex]

[tex]\rightarrow[/tex]The square cancels the square root of a number. Therefore, if we cancel the square root with a square in the above expression, we get,

➾[tex]\sf{\sqrt{9}}[/tex] = ±3
