A supervisor records the repair cost for 17 randomly selected stereos. A sample mean of $66.34 and standard deviation of $15.22

are subsequently computed. Determine the 80% confidence interval for the mean repair cost for the stereos. Assume the population is approximately normal. Find the critical value that should be used in constructing the confidence interval.

Ted has the following triangle dimensions.
Alla [95]

Answer:  <em>D) </em><u><em>He cannot construct a triangle</em></u>

Step-by-step explanation:

For a triangle to be possible <u>the largest side must be less than the sum of other two sides .</u>

In the given question largest side is 23 while other two sides are 8 and 14

Therefore for triangle to be possible 23 should be less than (8+14) but 23 > (8+14) .

Thus he can not construct a triangle using the given sides.

Hence correct option is <u><em>D)He cannot construct a triangle.</em></u>

Answer:

b=\frac{1}{6}

Step-by-step explanation:

In f(x)=a\cos(b(x-c))+d, b represents a constant related to the period of the function. Here's how it's related:

b=\frac{2\pi}{T}, where T is the period of the function.

We're given T=12\pi, so solving for b:

b=\frac{2\pi}{12\pi}=\boxed{\frac{1}{6}}

Calculate the heigh (x) of the tree
marta [7]

Answer:

<h2>87 feet</h2>

Solution,

tan \: theta =  \frac{opposite}{adjacent}

tan \: 60 =  \frac{h}{50}  \\ 5 \: tan \: 60 = h \\ h = 50 \: tan \: 60 \\ h = 87 \: feet

hope this helps..

Good luck on your assignment..
