Alika [10]

Answer:

The distance between them is 230.65 miles

Step-by-step explanation:

Here we use the Cosine formula

a^2 = b^2 + c^2 - 2bc\ cos\ A\\\\a^2 = 200^2 + 300^2 - 2\times 200\times 300cos50^{\circ}\\\\= 40,000 + 90,000 - 120,000cos50^{\circ}\\\\= 130,000 - 120,000 \times 0.64\\\\= 130,000 - 76,800\\\\a^2= 53,200\\\\a = \sqrt{53,200} \\\\= 230.65\ miles\ per\ hour

Now the distance for one hour is

= 230.65 ÷ 1

= 230.65 miles

The hourly wages of a sample of 130 system analysts are given below.
atroni [7]

Answer: b. 30%

Step-by-step explanation:

  • A measure of relative variability is known as coefficient of variation. It is the ratio of the standard deviation to the mean.

i.e. CV=\dfrac{\sigma}{\mu}

Given: mean =  \mu=90

Variance = \sigma^2 = 729

\sigma=\sqrt{729}=27

Now, CV=\dfrac{27}{90}=0.3

in percent , CV= 0.3\times100\%= 30\%

Hence, correct option is  b. 30%.
