Answer:

BD = 4.99 units

Step-by-step explanation:

Consider the triangle ABD only.

The angle formed is 31 degrees which occurs between two sides that are AD and BC.

We know that for a right angled triangle, the angle can always be taken as an angle between hypotenuse and base.

Thus, The perpendicular sides is then 3 units, where base is BD and Hypotenuse is AD

Using formula for tanθ

tanθ = Perpendicular/Base

tan31 = 3/BD

0.601 = 3/BD

BD = 3/0.601

BD = 4.99 units

If nothing is known about the shape of the distribution of a quantitative variable, what percentage of data fall within 2 standa
Nezavi [6.7K]
<span>At least 75% of the data will fall within 2 standard deviations of the mean. This is tricky problem. Usually when you're dealing with standard deviation, you have a bell curve, or something close to a bell curve and for such a data distribution, there will be approximately 95% of the data within 2 standard deviations of the mean. But if you don't know that you have a bell curve, you have to fall back to Chebyshev’s Theorem, which states that at least 75% of the data points will fall within 2 standard deviations of the mean for any set of numbers.</span>

arlik [135]

Answer:

The answer to this question can be defined as follows:

Step-by-step explanation:

In the first point:

Yes, the Finite Floating Point Structures are considered  Where \beta = 7

\to \frac{8}{7}= (1.1)_7

\bold{= 1 \times 7^0 + 1 \times 7^{-1}}\\\\

In the second point:

There is no device with a finite floating-point since the right side is  

This equality never happens, then, with the rational numbers (\alpha_i and \beta is rational).

Which type of transformation or sequence of transformations will map the preimage ∆ABC onto image ∆A'B'C'?
ollegr [7]
The transformation is a reflection with x-axis as the axis of reflection. Reflection is a type of transformation in which the transformed image is simply a mirror image of the original shape over a line or axis of reflection.
