Answer:

Theta = 59 degrees

Step-by-step explanation:

Here, we want to get the value of the marked angle

To do this, we use the appropriate trigonometric ratio

From what we have,

The side 42 ft is adjacent the angle given

The side facing the right angle is 82 ft

The trigonometric ratio that connects the adjacent and the hypotenuse is cosine. It is the ratio of the adjacent to the hypotenuse

Cos theta = 42/82

theta = cos^-1 0.5122

theta= 59.189

To the nearest degrees, this is 59 degrees

For a data consisting of 9 observations, the sum of 9 values is 360 and the sum of squares of deviation taken from the mean is 2
maxonik [38]

Answer:

4 ; 32

Step-by-step explanation:

Given that :

Number of observations, n = 9

Let observations = X

ΣX = 360

The mean, (m) is calculated using the formula :

m = ΣX / n

m = 360 / 9

m = 4

Σ(X - m) = 288 (sum of square of deviation )

Variance is calculated using the formula :

[Σ(X - m) / n]

Variance = Sqrt(288 / 9)

Variance = 32
