Filling in the given value, you have

... (sin θ)² + (3/4)² = 1

... (sin θ)² = 1 - 9/16 = 7/16 . . . . . . . subtract the constant on the left

... sin θ = √(7/16) . . . . . . . . . . . . . . take the square root

... sin θ = (√7)/4

For ten school days, the numbers of bikes parked at a school bike rack are 10, 12, 8, 11, 13, 9, 2, 1, 9, and 12​.
Lapatulllka [165]

The mean number is 8.7 and the outliers 1 and 2 reduce the mean value

<h3>How to determine the mean number?</h3>

The dataset is given as:

10, 12, 8, 11, 13, 9, 2, 1, 9, and 12​.

The mean number is calculated using:

Mean = Sum/Count

So, we have:

Mean = (10+ 12+ 8+ 11+ 13+ 9+ 2+ 1+ 9+12​)/10

Evaluate

Mean = 8.7

Hence, the mean number is 8.7

<h3>The outlier and how it affects the mean</h3>

Outliers are relatively far from other data elements of the dataset

In the given dataset, 1 and 2 are far from other data element.

So, the outliers are 1 and 2

Because 1 and 2 smaller than other data elements, they affect the mean by reducing the mean value

From a point 80m from the base of a tower, the angle of elevation to the top of the tower is 28 degrees how tall is the tower
Nadusha1986 [10]

The height of the tower is 42.54 m.

Solution:

The reference image of the answer is attached below.

Given data:

BC = 80 m, ∠C = 28°

$\tan\theta = \frac{\text{Opposite}}{\text{Adjacent}}

$\tan28^\circ = \frac{AB}{BC}

$\tan28^\circ = \frac{h}{80}

$0.5317 = \frac{h}{80}

Multiply by 80 on both sides, we get

42.536 = h

Switch the sides.

h = 42.536

h = 42.54 m

The height of the tower is 42.54 m.
