Solve for x and y...............

sladkih [1.3K]

Answer:

9. $x=30, y=10\sqrt{3}$

11. $x=5\sqrt{3}, y=10\sqrt{3}$

Step-by-step explanation:

$\sin x=\dfrac{10}{20}\\x=\sin^{-1}\left( \dfrac{1}{2} \right)=30^{\circ}\\y=\sqrt{20^2-10^2}=\sqrt{400-100}=\sqrt{300}=10\sqrt{3}$

11)

$\tan 60= \dfrac{15}{x}\\x=\dfrac{15}{\tan 60}=5\sqrt{3}\\y=\sqrt{(5\sqrt{3})^2+15^2}=\sqrt{75+225}=\sqrt{300}=10\sqrt{3}$

Hope this helps!

What is the variance of the following data? If necessary, round your answer to two decimal places 600,470,170,430,300

Mkey [24]

Answer:

72112885110079700000000000000.00

Step-by-step explanation:

X(mean) = (600470170430300 + 23056 + 22123 + 21704 + 20365) / 5 = 120094034103510

n=5

S²(variance) = ((600470170430300-120094034103510)²+(23056-120094034103510)²+(22123-120094034103510)²*+(21704-120094034103510)²+(20365-120094034103510)²/(5-1)

S² = 72112885110079700000000000000.00
