Answer:

Fertilizer runoff from nearby farms

Explanation:

Fertilizer contains an excess of nutrients, including phosphorus. When fertilizer runs into nearby waterbodies (such as rivers), algae uses these nutrients as a food source, and an algal bloom will occur due to that large sum of available nutrients.

15. For a random sample of n = 64, find the probability of a sample mean being

mart [117]

Answer:

0.9726

Explanation:

The computation of the probability of a sample mean is shown below:

$P(\bar x < 24.3)$

To find the probability first we have to determine the z score which is

$z = \frac{\bar x - \mu_{\bar x}}{\sigma_{\bar x}} \\\\ = \frac{\bar x - \mu }{\frac{\sigma}{\sqrt{n} } } \\\\ = \frac{24.3 - 24}{\frac{1.25}{\sqrt{64} } }$

= 1.92

Now probability is

$P(\bar x < 24.3) \\\\= P(z < 1.92)$

= 0.9726

Hence, the probability of the sample mean is 0.9726

We simply applied the above formulas to determined the probability of a sample mean and the same is to be considered

A 10-foot tree casts a 17-foot shadow directly down a slope when the angle of elevation of the sun is 42o (see figure). Find \th

inna [77]

The angle of elevation of the ground is the angle between the ground and the line of sight

The angle of elevation of the ground is 30.46 degrees

<h3>How to calculate the angle of elevation</h3>

The angle of elevation is calculated using the following tangent ratio

$\tan(\theta) = \frac{10}{17}$

Evaluate the quotient

$\tan(\theta) = 0.5882$

Take the arc tan of both sides

$\theta = \tan^{-1}(0.5882)$

Using a calculator, we have:

$\theta$ = 30.46

Hence, the angle of elevation of the ground to the nearest tenth of a degree is 30.46 degrees
