Solve for the missing side round to the nearest 10th (look at image)

SIZIF [17.4K]

Answer:

14.3

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

14^2 + 3^2 = c^2

196 + 9 = c^2

205 = c^2

Take the square root of each side

sqrt(205) = sqrt(c^2)

14.31782106 = c

Rounding to the nearest tenth

14.3 = c

1. Suppose you have just received a shipment of 100 iPads where 7 iPads are defective. To determine whether or not you will acce

Lyrx [107]

Answer:

$p(x\geq 1)=0.1975$

Step-by-step explanation:

the probability that x iPads are defective in the sample follows a hypergeometric distribution, so it is calculated as:

$p(x)=\frac{kCx*((N-k)C(n-x))}{NCn}$

Where $aCb=\frac{a!}{b!(a-b)!}$

Because we have a N elements with k elements that are defective and we are going to take a sample of n elements. So, replacing N by 100, k by 7 and n by 3, we get:

$p(x)=\frac{7Cx*((100-7)C(3-x))}{100C3}$

Now, the probability of rejecting the shipment is the probability that at least one iPad of the sample is defective, so:

$p(x\geq 1)=p(1)+p(2)+p(3)$

Then:

$p(1)=\frac{7C1*((100-7)C(3-1))}{100C3}=0.1852\\p(2)=\frac{7C2*((100-7)C(3-2))}{100C3}=0.0121\\p(3)=\frac{7C3*((100-7)C(3-3))}{100C3}=0.0002$

Finally, the probability of rejecting the shipment is:

$p(x\geq 1)=0.1852+0.0121+0.0002=0.1975$

Which expression is equivalent to the following complex fraction?

mamaluj [8]

The equivalent expression of $1 - \frac{1}{x} \div 2$ is $\frac{2x - 1}{2x}$

<h3>How to determine the equivalent expression?</h3>

The expression is given as:

1 minus StartFraction 1 Over x EndFraction divided by 2

Rewrite properly as:

$1 - \frac{1}{x} \div 2$

Express the division as product

$1 - \frac{1}{x} \times \frac 12$

Evaluate the product

$1 - \frac{1}{2x}$

Take the LCM

$\frac{2x - 1}{2x}$

Hence, the equivalent expression of $1 - \frac{1}{x} \div 2$ is $\frac{2x - 1}{2x}$
