Answer: 33.9 inches

Step-by-step explanation:

Assuming you meant to write that the length of the right arm holding the torch is 1 inch:

The statue is 305 feet tall and the replica is 9 inches tall.

If the replica's right arm is 1 inch, the actual arm will be:

= 1 * 305/9

= 33.9 inches

<em>If right arm of replica was not 1 inch, use this answer as reference. </em>

A company makes rubber rafts. 12% of them develop cracks within the first month of operation. 27 new rafts are randomly sampled
rewona [7]

The probability that the number of tested rafts that develop cracks is no more than 3 is <u>.00006</u>.

The true proportion, p for the population is given to 0.12.

Thus, the mean, μ, for the sample = np = 27*0.12 = 3.24.

The sample size, n, given to us is 27.

Thus, the standard deviation, s, for the sample can be calculated using the formula, s = √{p(1 - p)}/n.

s = √{0.12(1 - 0.12)}/27 = √0.003911 = 0.0625389.

We are asked to calculate the probability that the number of tested rafts that develop cracks is no more than 3, that is, we need to calculate P(X ≤3).

P(X ≤ 3)

= P(Z ≤ {(3 - 3.24)/0.0625389) {Using the formula z = (x - μ)/s}

= P(Z ≤ -3.8376114706)

= .00006 {From table}.

Thus, the probability that the number of tested rafts that develop cracks is no more than 3 is <u>.00006</u>.

Find the measure of a base angle of a isosceles triangle if the measure of the vertex angle is 100
Lorico [155]
Sum of the angles in a triangle ... 180!

Isosceles, two of them are equal: 100 + 2x  =180, x = 40 degrees! <- That's the answer ;)

Which of the following best describes the equation below?
yarga [219]

linear → D

The equation of a line ( linear ) in ' slope- intercept form ' is

y = mx + c

where m is the slope and c the y- intercept

Here the variable is i but the equation is of the form y = mx + c

Thus is a linear equation.
