Why is it important to distress?

Anna35 [415]

I agree with the person above.
Prolonged stressing causes mental illnesses such as depression, anxiety, and personality disorders.
It causes physical illnesses such as cardiovascular disease, high blood pressure, abnormal heart rhythms, heart attacks, heart disease, and strokes.

Ways to distress are things like exercising, eating healthy, meditate, take a deep breath in and out, and find a hobby that helps you distress. Also I would full heartedly recommend watching Bob Ross.

Each of 6 samples has a different standard deviation. How many of the 6

ivann1987 [24]

The number of six samples that could belong to the same population is equivalent to six.

Option A is the correct answer.

<h3>What is the standard deviation?</h3>

The standard deviation is the indicator to determine the variation between the set of amounts as given in the statistical information.

The population is referred to as the entire information being prescribed in data relating to any concept. If the number of samples in a population is 10, then the samples in the same population will also be 10. This shows the number of samples is always equal to the samples in the same population.

Therefore, the six samples belong to the same population comprising of six samples having varied standard deviations.

Patrick drives from p to q at an average speed of 40mph.

Bumek [7]

The distance in miles from P to Q is 12 miles

<h3>Distances and speed</h3>

Let the distance from P to Q be "d"

Since the formula for calculating speed is expressed as:

s =d/t

For the distance of P to Q

40 = d/t

d = 40t

If he drives back at an average speed of 45mph and 2 mintes less, then;

45 = d/t - 0.033

d = 45 (t - 0.033)

Equating both distances

40t = 45(t - 0.033)

40t = 45t - 1.485

-5t = -1.485
t = 0.297

Get the distance from P to Q:

d = 40(0.297)
d = 11.88 miles

Hence the distance in miles from P to Q is 12 miles
