The Red Line in the figure is an altitude of triangle hjl. Using right angle trig and properties of equality, y sin L = x = z si
aivan3 [116]

Answer:

\Large \boxed{\mathrm{\bold{C}}}

Step-by-step explanation:

\sf \displaystyle sin(\theta) =\frac{opposite}{hypotenuse }

\sf \displaystyle sin(L) =\frac{x}{y}

\sf \displaystyle sin(H) =\frac{x}{z}

\displaystyle \sf \frac{sinL}{z} =\frac{sinH  }{y}

\displaystyle \sf \frac{\frac{x}{y} }{z} =\frac{\frac{x}{z} }{y}

Simplifying the expression.

\sf \displaystyle \frac{x}{yz } = \frac{x}{yz} \ (true)

\displaystyle \sf \frac{z}{sinL} =\frac{y}{sinH}

\displaystyle \sf \frac{z}{\frac{x}{y}} =\frac{y}{\frac{x}{z}}

Multiplying both sides by x.

\sf yz=yz  \ (true)

Peter wants to test an assumption on the number of trees that tested positive for a particular infestation. He decides to focus
LUCKY_DIMON [66]

Answer:

H0 : P ≤ 0.12

H1 : P > 0.12

Step-by-step explanation:

12% = 12/ 100 = 0.12

Given the population proportion, P = 0.12

The claim is the alternative hypothesis, H1 ; which is to test if more than 12% of trees have been infested.

Hence, the alternative hypothesis will be ;

H1 : P > 0.12

The null hypothesis which is the initial truth is always the opposite of the alternative hypothesis, Therefore, we write our null as ;

The null hypothesis ; H0 : P ≤ 0.12

Therefore, we have :

H0 : P ≤ 0.12

H1 : P > 0.12
