Given a 30-60-90 triangle with a long<br> leg of 9 in, determine the length of the<br> hypotenuse.
aniked [119]

Answer:

10.38 in

Step-by-step explanation:

Long side would be opposite to 60°.

Since, side opposite to 60° is root 3 upon 2 times of hypotenuse.

9 =  \frac{ \sqrt{3} }{2} \times hypotenuse \\  \\ hypotenuse =  \frac{9 \times 2}{ \sqrt{3} }  \\  =  \frac{18}{ \sqrt{3} }  =  \frac{18 \sqrt{3} }{3}  = 6 \sqrt{3}  = 6 \times 1.73 \\   \:  \:  \: \red{ \bold{hypotenuse = 10.38 \: in}}

Of the 200 students surveyed at the local high school, 126 say that they prefer earlier start times for school. What is the mean
ra1l [238]

Answer:

The mean of sampling distribution of the proportion of the students who prefer later start times for school

                        μₓ = p = 0.63

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given sample size 'n' =200

given data Of the 200 students surveyed at the local high school, 126 say that they prefer earlier start times for school

sample proportion

                        p = \frac{x}{n} = \frac{126}{200} = 0.63

The mean of sampling distribution of the proportion of the students who prefer later start times for school

                        μₓ = p = 0.63

Standard deviation of the proportion

                     S.D = \sqrt{\frac{p(1-p)}{n} } = \sqrt{\frac{0.63(1-0.63)}{200} } = 0.034

Try dividing fractions 4/5÷1/3
Elden [556K]
2 2/5 because math if you need me to explain I can!
4/5 ÷1/3, the first step in dividing fractions is to flip the second one (its reciprocal)
4/5 ÷ 3/1 then change the sign to ×
4/5 × 3/1 which would then equal
12/5 now simplify, 5 goes into 12 two times with a remainder of 2 so that leaves you like
