Calliope Is going to buy a television for $1349. If sales tax is 8%, find the price of the television including tax.
Anna007 [38]

Answer:

The price including tax is $1,456.92

Step-by-step explanation:

First we need to convert our percentage into a decimal.

0.08

Now we need to multiply our price by the sales tax.

$1,349.00 × 0.08 = $107.92

Our sales tax is $107.92.

Added to our price it's $1,456.92.

Determine the missing coordinate in the ordered pair (?,5) so that it will satisfy x+6y=18
Mkey [24]
We can start by rewriting the equation:

x + 6y = 18

Because we already have our y-coordinate, we can plug it in for the equation.

x + 6(5) = 18

Now we can simplify.

x + 30 = 18

Since we are adding 30 to a number to get another number less than 30, we can presume that x equals a negative number. 30 - 18 = 12. That means that x would equal -12.

Now we can plug -12 in as x to see if our equation is valid.

-12 + 30 = 18

Because negative 12 added to 30 does equal 18, we know that our equation is correct.

Your final answer: The missing coordinate is -12. The final ordered pair is (-12,5). If you need help understanding, let me know and I will gladly assist you.

What is the standard deviation for the data set?
aleksandr82 [10.1K]

Answer:

The standard deviation is 22.6 to the nearest tenth

Step-by-step explanation:

* Lets study how to find the standard deviation (σ) for data set

- First step find the mean of the data

∵ The mean = the sum of the data ÷ the number of the data

# The sum of the data is

  359 + 320 + 365 + 310 + 349 + 351 + 310 + 314 + 364 = 3042

# The number of the data is 9

∴ The mean = 3042 ÷ 9 = 338

- Second step find the difference between each data and the mean

 and square the difference

# 359 - 338 = 21 ⇒ (21)² = 441

# 320 - 338 = -18 ⇒ (-18)² = 324

# 365 - 338 = 27 ⇒ (27)² = 729

# 310 - 338 = -28 ⇒ (-28)² = 784

# 349 - 338 = 11 ⇒ (11)² = 121

# 351 - 338 = 13 ⇒ (13)² = 169

# 310 - 338 = -28 ⇒ (-28)² = 784

# 314 - 338 = -24 ⇒ (-24)² = 576

# 364 - 338 = 26 ⇒ (26)² = 676

- Third step find the variance (σ²)

# Add all the square difference and divide the sum by the

  number of data

∴ σ² = (441 + 324 + 729 + 784 + 121 + 169 + 784 + 576 + 676) ÷ 9

∴ σ² = 4604 ÷ 9 = 511.5555556

- Fourth step find the standard deviation σ  it is the square root of

 the variance

∴ σ = 22.6 to the nearest tenth

* The standard deviation is 22.6 to the nearest tenth
