What is the standard deviation of the data set?

1 answer:

Temka [501]3 years ago

5 0

The Standard Deviation is a measure of how spread out numbers are. Standard deviation can be calculated by the expression as follows:

s = √∑(x - x(mean))^2/n-1

x(mean) = 24

s = √∑(x - 24)^2 / 7-1

Find the center of the circle whose equation is x² + y² = 4.

Varvara68 [4.7K]

Answer:

The center of circle is $(0,0)$

Step-by-step explanation:

We need to find the center of the circle of the equation $x^{2}+y^{2}=4$

Since, the general equation of circle is $(x-h)^{2}+(y-k)^{2} = r^{2}$

Where (h,k) is center of circle and r is radius.

Re-write the circle equation is $x^{2}+y^{2}=4$ as,

$x^{2}+y^{2}=2^{2}$

Compare $x^{2}+y^{2}=2^{2}$ with $(x-h)^{2}+(y-k)^{2} = r^{2}$

so, $(x-0)^{2}+(y-0)^{2} = 2^{2}$

Hence, the center of circle is $(0,0)$

A spinner is divided into six equal-sized sectors labeled 1 through 6. Dwayne spins this spinner 12 times. Let X

slavikrds [6]

Answer:

b) μ = 2 and σ = 1.29

Step-by-step explanation:

<u><em>Step(i):-</em></u>

<em>Given that the A spinner is divided into six equal-sized sectors labelled 1 through 6</em>

<em>Given that the probability of labelled '1'</em>

<em> </em> $p = \frac{1}{6}$ =0.16

<em> q = 1-p = 1- 0.16 = 0.84</em>

Let 'X' be a random variable in binomial distribution

The mean of the binomial distribution

μ = n p

μ = $12 (\frac{1}{6} ) = 2$

<em>The mean of the binomial distribution = 2</em>

<u><em>Step(ii):-</em></u>

The standard deviation of X

σ $= \sqrt{npq}$

σ = $\sqrt{12(0.16)(0.84}$

σ = $1.269$

<em>The standard deviation of the binomial distribution</em>

<em> </em> σ = $1.269$

<u><em></em></u>

<u><em></em></u>
