the following data have been aranged in ascending order. if their median is 63 find value of x. 34,37,53,55,x,x+2,77,83,89and100​

Answers

Answer 1

Answer:

The value of x is 62

Step-by-step explanation:

Given data is:

34,37,53,55,x,x+2,77,83,89and100​

As the number of values is 10 (which is even number of values) i.e. n=10

The median will be the average of two middle values.

[tex]M = \frac{1}{2}(\frac{n}{2}th\ value + \frac{n+2}{2}th\ value})\\M = \frac{1}{2}(\frac{10}{2}th\ value + \frac{10+2}{2}th\ value})\\M = \frac{1}{2}(5th\ value + 6th\ value})\\[/tex]

As it is already given that the median is 63

Putting M=63

[tex]63 = \frac{1}{2}(x+x+2)\\126 = 2x+2\\126-2 = 2x\\124 = 2x\\\frac{2x}{2} = \frac{124}{2}\\x = 62[/tex]

Hence,

The value of x is 62

Reduce in LOWEST terms: 4 dimes and 2 nickels

Answers

Answer:

2 quarters

Step-by-step explanation:

4 dimes = 40 cents

2 nickels = 10 cents

40 + 10 = 50 cents

So 50 pennies = 50 cents

So 10 nickels = 50 cents

So 5 dimes = 50 cents

So 2 quarters = 50 cents

Jennelle went shopping for school clothes. She spent $137 at one store and $96 at another store. She had $87 left.

How much money did Jennelle take shopping?

Answers

Answer:

Jennelle actually brought  320$

Step-by-step explanation:

She spend on first store 137$

2nd store                      96

she left   87 which is after he spend the money in the stores

so you add 137$ and 96$ to get 233 then usually this kind of question asks about how much he left. But it already gave us how much she left

so if you add it you will find out how much he brought to the shopping

so  233+87 is equal to 320 $

A bookshelf is 42 inches long. How many books of length 1\frac{1}{2}1 2 1 ​ inches will fit on the bookshelf? Explain your reasoning

Answers

Answer: See explanation

Step-by-step explanation:

Your question isn't well written but I saw an identical question:

A bookshelf is 42 inches long. Each book is 1 1/4 inches wide. How many books will fit on the shelf?

For us to solve this, we would divide the length of the bookshelf by the width of each book. This would be:

= 42 ÷ 1 1/4

= 42 ÷ 5/4

= 42 × 4/5

= 33 3/5

Therefore, the number of books that will fit on the shelf is 33.

David bought 9 t-shirts for $36. The store charges a 6.5% sales tax on the total cost. What will be the
total cost of the shirts, including tax?

Answers

Answer:

In order to calculate the sales tax of an item, we need to first multiply the pre-tax cost of the item by the sales tax percentage after it has been converted into a decimal. Once the sales tax has been calculated it needs to be added to the pre-tax value in order to find the total cost of the item. Let's start by working with an example. If a magazine costs $2.35 and has a 6% sales tax, then what is the total cost of the item. First, we need to convert the sales tax percentage into a decimal by moving the point two spaces to the left.

6%→0.06

Now, we need to multiply the pre-tax cost of this item by this value in order to calculate the sales tax cost.

\textup{Sales tax}=0.06\times\$2.35

\textup{Sales tax}=\$0.141

Round to two decimal places since our total is in dollars and cents.

\textup{Sales tax}=\$0.14

Last, add this value to the pre-tax value of the item to find the total cost.

\textup{Total cost}=\textup{Pre-tax value}+\textup{Sales tax}

\textup{Total cost}=\$2.35+\$0.14

\textup{Total cost}=\$2.49

Step-by-step explanation:

Total cost of 9 t-shirts = $36

Percentage of tax on the total cost = 6.5%

Tax on the total cost :

[tex]= 6.5\% \: of \: \: 36[/tex]

[tex] = \frac{6.5 \times 36}{100}[/tex]

[tex] = \frac{234}{100} [/tex]

[tex] = \color{hotpink}\$ \: 2.34[/tex]

Thus, the total tax on the shirts = $2.34

Total cost of the shirts including tax :

[tex] = 36 + 2.34[/tex]

[tex] =\color{hotpink} \bold{\$ \: \: 38.34}[/tex]

Therefore, the total cost of the shirts including tax = $38.34

I need the perimeter

Answers

Answer:

42

Step-by-step explanation:

to find the perimiter youre gonna want to add up all the sides you already have,

so we have 4, 4, 11, and 6.

the reason we dont count the other 4 inside of the figure is because that is inside of it, so we would consider that perimiter

as we see there are other sides not labeled. we have to use that area four to help us.

for the top left side, we do 6 - 4 = 2

for the bottom right side, we do 11 - 4 = 7

then, as we see at the top right we have a four labeled, these look the same width so add a four.

and at the top left, we see another four so add that.

then, add up everything giving you 42.

You want to buy some beans . A 6 - ounce package costs $2.16 . A 15 - ounce package costs $5.92 . A 20 - ounce package costs $7.60 . Which package is the best buy

Answers

Step-by-step explanation:

Given that,

A 6 ounce package costs $2.16

A 15 ounce package costs $5.92

A 20 ounce package costs $7.60

So,

Cost of 1 ounce of package = 2.16/6 = $0.36

Cost of 1 ounce of package = 5.92/15 = $0.394

Cost of 1 ounce of package = 7.6/20 = $0.38

Hence, 'a 6 ounce package costs $2.16' is the best deal to buy.

Solve the equation for h:

8.23 + h = 11.203

Answers

Answer:

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

h+8.23=11.203

Step 2: Subtract 8.23 from both sides.

h+8.23−8.23=11.203−8.23

h=2.973

The angle of elevation to the top of a particular skyscraper in New York is found to be 12 degrees from the ground at a distance of 1.3 mi from the base of the building. Using this information, find the height of the skyscraper. * 20 points a. 1560 ft b. 2918 ft c. 1459 ft

Answers

Answer:

The height of the skyscraper is 1,459 ft. Choice c

Step-by-step explanation:

Right Triangles

The ground and the building form a right angle (90°). In the right triangles, the trigonometric ratios are satisfied. To solve the problem we use the tangent ratio, defined as:

[tex]\displaystyle \tan\theta=\frac{\text{opposite side}}{\text{adjacent side}}[/tex]

The angle of elevation from which the skyscraper can be seen is θ=12°. The opposite side of this angle is the height of the skyscraper H and the adjacent side is the distance from the ground X=1.3 miles.

Converting miles to feet: X=1.3*5,280 = 6,864 ft

Applying the tangent ratio to the angle of elevation:

[tex]\displaystyle \tan 12^\circ=\frac{H}{6,864}[/tex]

Solving for H:

[tex]H=6,864\tan 12^\circ[/tex]

Calculating:

H = 1,459 ft

The height of the skyscraper is 1,459 ft. Choice c
