If the sum of squares for a sample containing 51 items equals 200, what is the standard deviation?

Mathematics

Mashcka [7]2 years ago

The standard deviation is 1.98. Option A is correct.

The standard deviation formula is given as

  • \sigma = \sqrt{\frac{SS}{n} }

where:

  • SS is the sum of squares = 200
  • n is the sample size = 51

Substitute the given parameters into the formula to have:

\sigma = \sqrt{\frac{200}{51} }\\\sigma = \sqrt{3.922}\\\sigma = 1.980

Hence the standard deviation is 1.98

The table shows the gallons of water in a pool over time.
Valentin [98]

Answer:

6 gallons per minute

Step-by-step explanation:

Let the function that models the quantities of water, Q (in gallons) in a pool over time, t (in minutes), is  

Q = a + bt ........... (1)

Now, Q(t = 0) is given to be 50 gallons.

So, a = 50 and b denotes the rate at which the quantity of water in the pool is decreasing and it is given by the slope of equation (1).

Now, two points on the graph are (0,50) and (1,44).

So, the slope = b =  = - 6 gallons per minute.

Therefore, the equation of this situation is given by Q = 50 - 6t, where the slope is equal to - 6 gallons per minute. (Answer)

a hamster wheel has a 7 inch diameter. How many feet will a hamster travel in 100 revolutions of the wheel?
Firdavs [7]
1 revolution = circumference of the wheel = pi * diameter

= 3.14 * 7 inch

so 100 revolution = 100 * 3.14 * 7 = 2198 inches

= 2198 / 12 = 183.17 feet
