. Use the statistical features of your calculator to find the mean and the standard deviation to the nearest tenth of a data set

uysha [10]

Answer:

Mean = 1.9

Standard deviation = 0.6

Step-by-step explanation:

The Mean is calculate by the formula:

$Mean = \frac{\text{Sum of all the observation}}{\text{Total number of observation}}$

⇒ $Mean = \frac{24.9+24.7+24.7+23.4+27.9}{5} = 1.85$

Thus Mean to the nearest tenth is 1.9

Standard Deviation is the square root of sum of square of the distance of observation from the mean.

$Standard deviation(\sigma) = \sqrt{\frac{1}{n}\sum_{i=1}^{n}{(x_{i}-\bar{x})^{2}} }$

where, $\bar{x}$ is mean of the distribution.

Putting all values in the formula, We get

Standard Deviation = 0.597 ≈ 0.6

Trigonometry (ASAP) (Urgent)

Olin [163]

Answer:

h = 1.403733341286

Step-by-step explanation:

17.

the triangle of sides ‘l’ and ‘l-h’ is a right angled triangle.

Then

$\cos \theta =\frac{l-h}{l}$

Then

$l\cos \theta =l-h$

Then

$h=l-l\cos \theta$

18.

For l = 6 and θ = 40 :

$h=l-l\cos \theta$

= 6-6cos(40)

= 1.403733341286
