A 34-foot tall utility pole is supported by two wires that are anchored 8feet from the base of the pole.how many feet of wire is needed for the support wires?

70

Step-by-step explanation:

So this is essentially creating two (equivalent) right triangles.

The sides of the triangle are the 34 foot pole and the 8 feet of ground in between the pole and the wire.

Knowing this, we can use the pythagorean theorem to solve for the hypotenuse.

a^2+b^2=c^2

Plug in what we know

34^2+8^2=c^2

1156+64=c^2

1220=c^2

The square root of 1220 is approximately 35 feet

So if each triangle uses ~35 feet of wire, then in total there is ~70 feet used

98% Confidence interval:  (0.5483,0.6891)

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 257

Number of adults total body length was 28 feet or longer, x = 159

98% Confidence interval:

Putting the values, we get:

is the required 98% confidence interval.
