Each leg of a 45-45-90 triangle has a length of 6 units. What is the length of its hypotenuse?

andreyandreev [35.5K]

Use the Pythagorean theorem:
$(\hbox{one leg})^2+(\hbox{the other leg})^2=(\hbox{hypotenuse})^2 \\
6^2+6^2=x^2 \\
6^2 \times 2=x^2 \\
\sqrt{6^2 \times 2}=x \\ \sqrt{6^2} \times \sqrt{2}=x \\ 6\sqrt{2}=x
$

The length of the hypotenuse is 6√2 units.

Division A reports the following data: Sales = $180,000, Net income = $18,000, Average'assets

Karolina [17]

Company A is operating more efficiently

Step-by-step explanation:

Given parameters:

Division A:

Sales = $180,000

Net income = $18,000

Average assets = $72,000

Division B:

Sales = $60,000

Net income = $9,600

Average assets = $48,000

Unknown:

Division operating more efficiently = ?

Solution:

Efficiency measures the relationship between the output from a business and the input into it. Here, the efficiency is the relationship between the net income and the average assets. it can be expressed as a percentage or ratio.

The net income is the profit derived from sales of a company's products.

The higher the value the more efficient a company is.

Efficiency = $\frac{net income}{Average assets}$ x 100

Efficiency of division A = $\frac{18000}{72000}$ x 100 = 25%

Efficiency of division B = $\frac{9600}{48000}$ x 100 = 20%

Division A has a higher efficiency compared to B

Using descriptive statistics, you have found out that it takes an average of 40 minutes to complete a mid-term examination in IS

choli [55]

Answer:

b. exam completion time is negatively skewed

Step-by-step explanation:

A data distribution is said to be negatively skewed when <em>median</em> value of the distribution is higher than the <em>average</em> value of the distribution.

In this example

average mid-term completion time is 40 minutes

median mid-term completion time is 55 minutes.

thus median > mean, so the mid-term completion time is negatively skewed. Negatively skewed distributions are also called left-skewed.

Which equation is equivalent to 2 Superscript 4 x Baseline = 8 Superscript x minus 3?

marshall27 [118]

Answer:

2 Superscript 4 x Baseline = 2 Superscript 3 x minus 9

8^(x-3) = 2^(3x-9)

Step-by-step explanation:

2⁴ × 8^(x - 3)

2⁴ × (2³)^(x-3)

2⁴ × 2^(3x - 9)

Since the bases are same now, powers can be added

2^(4 + 3x - 9)

2^(3x - 5)
