Answer:

12.5r + 200 = 12.5*2r

Step-by-step explanation:

<h3>Given</h3>

Rate of Hoppertunity = r

Rate of Dortmund = 2r as it is twice as fast

<h3>Solution</h3>

Let the distance Hoppertunity runs be d, then the distance Dortmund runs is d + 200 m

Since it took 12.5 seconds Dortmund to catch Hoppertunity, it can be expressed as:

d = 12.5r for Hoppertunity
d + 200 =12.5*2r for Dortmund

<u>By replacing d in the second equation, we get:</u>

12.5r + 200 = 12.5*2r

<u>Soving</u>:

12.5r = 200
r = 200/12.5
r = 16 m/sec

Hoppertunity's rate is 16 m/sec

Dortmund's rate is 32 m/sec

Please help me with this real quick

tia_tia [17]

Answer: 7.5 miles

Step-by-step explanation:

think of it as a triangle; the bold line is the hypotenuse, or x.

8 |\ x

|_\ it's not a good triangle but you get the point

and then get out pythagorean theorem: a^2+b^2=c^2

put the numbers in: 8^2 + 6^2 = x^2

do some math:

64+36=x^2

100=x^2 (and then find square root)

10=x

<u>BUT</u>, it said each unit was 3/4 of a mile, so we must multiply 10 by 3/4 to get the actual distance, which is 7.5

Answer:

IQ scores of at least 130.81 are identified with the upper 2%.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Mean of 100 and a standard deviation of 15.

This means that $\mu = 100, \sigma = 15$
