The length of a rectangular swimming pool is twice as long as its width. If the perimeter of the pool is
Nitella [24]

The perimeter of a rectangle is the sum of its sides, which are two widths and two lengths:

p=w+w+l+l

Since the length is twice the width, we have l=2w, and the formula for the perimeter becomes

p=w+w+2w+2w=6w

So, we have

6w=120 \iff w=\dfrac{120}{6}=20

Exponential Function:
vovangra [49]

Answer:

See below

Step-by-step explanation:

<em>On the graphs we see transformations of exponential functions</em>

<h3>Graphic 1 = Horizontal shift </h3>
  • f(x) = 2ˣ is the parent function
  • g(x) = 2ˣ⁺³ indicates shift to the left by 3 units
  • h(x) = 2ˣ⁻¹ indicates the shift to the right by 1 unit
<h3>Graphic 2 =Vertical shift</h3>
  • p(x) = (1/3)ˣ is the parent function
  • r(x) = (1/3)ˣ⁺³ indicates shift up by 3 units
  • q(x) = (1/3)ˣ⁻² indicates the shift down by 2 units

Using the Empirical Rule, it is found that:
AveGali [126]

Considering that the mean of the normal distribution is the same as the median, the median is of 88%.

<h3>What does the Empirical Rule state?</h3>

It states that, for a normally distributed random variable:

  • Approximately 68% of the measures are within 1 standard deviation of the mean.
  • Approximately 95% of the measures are within 2 standard deviations of  the mean.
  • Approximately 99.7% of the measures are within 3 standard deviations of the mean.

For the normal distribution, the median is the same of the mean, that is, the median is of 88%.
