Right scalene triangle

Step-by-step explanation:

The triangle that I made with 4cm, 7cm, and 8 cm. had a right angle and also has all unequal sides which is basically the exact definition of a right scalene triangle.

Ricardo throws a stone off a bridge into a river below. The stone's height (in meters above the water), xxx seconds after Ricard

Dominik [7]

For this case we have the following function:
w (x) = - 5 (x-8) (x + 4)
Rewriting we have:
w (x) = - 5 (x ^ 2 + 4x - 8x - 32)
w (x) = - 5x ^ 2 - 20x + 40x + 160
w (x) = - 5x ^ 2 + 20x + 160
Then, deriving we have:
w '(x) = - 10x + 20
We equal zero and clear x:
0 = -10x + 20
10x = 20
x = 20/10
x = 2 seconds
Substituting values:
w (2) = - 5 (2-8) (2 + 4)
w (2) = - 5 (-6) (6)
w (2) = 180 meters
Answer:
The maximum height that the stone will reach is:
w (2) = 180 meters

A researcher is interested in the lengths of brook trout, which are known to be approximately Normally distributed with mean 80

aliya0001 [1]

Answer:

$P(X$

And we can find this probability with the normal standard distirbution or excel and we got:

$P(z$

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

Solution to the problem

Let X the random variable that represent the lenghts of a population, and for this case we know the distribution for X is given by:

$X \sim N(80,5)$
