How many miles will a person run during a 10 kilometer race?

2 answers:

6 0

There are 1,61 kilometers in a mile or more correctly 1,60934 kilometers in a mile.
<span>But first, a short history.... Both kilometers and miles are units of measurement. They are used to measure distance. Miles are part of the imperial measurement system and kilometers are part of the metric measurement system. </span>
To calculate how many miles a person will run during a 10-kilometer race, you need to divide 10 kilometers by 1,61 miles (1,60934 rounded up to two digits).

Therefore your equation is as follows:

10÷1,61 or 10 000 meters ÷ 1 610 metres
1000 meters is equal to 1 kilometer.

The answer = 6, 21 miles.

Therefore, a person who runs 10 kilometers will run 6,21 miles

Suppose a shipment of 400 components contains 68 defective and 332 non-defective computer components . From the shipment you tak

Alona [7]

Answer:

The standard deviation for the number of defective parts in the sample is 1.88.

Step-by-step explanation:

The sample is with replacement, which means that the trials are independent, and thus, the binomial probability distribution is used to solve this question.

Binomial probability distribution

Probability of exactly x successes on n repeated trials, with p probability.

The expected value of the binomial distribution is:

$E(X) = np$

The standard deviation of the binomial distribution is:

$\sqrt{V(X)} = \sqrt{np(1-p)}$

68 defective out of 400:

This means that $p = \frac{68}{400} = 0.17$

From the shipment you take a random sample of 25.

This means that $n = 25$

Standard deviation for the number of defective parts in the sample:

$\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{25*0.17*0.83} = 1.88$

The standard deviation for the number of defective parts in the sample is 1.88.

What is the length of segment AB?

olasank [31]

Answer:

The answer is 6.403

Step-by-step explanation:

Using the pythagorean theorem, a^2+b^2=c^2, we can plug 4 units into a, and 5 units into b. Plugging these into the formula results in 4^2 + 5^2 = c^2. Simplifying, we get 16 + 25 = c^2. Simplifying even more, we get 41 = c^2. Using a calculator to get the square root of both sides results in c = 6.40312424.
