Answer:

$C=25^{\circ},\\a\approx 10.72,\\b\approx 11.83$

Step-by-step explanation:

The sum of the interior angles of a triangle is 180 degrees. Thus, angle C must be $180-90-65=25^{\circ}$ .

In any triangle, the Law of Sines is given by $\frac{\sin A}{a}=\frac{\sin B}{b}=\frac{\sin C}{c}$ .

Therefore, we have:

$\frac{\sin 90^{\circ}}{b}=\frac{\sin 25^{\circ}}{5},\\\\b=\frac{5\sin90^{\circ}}{\sin 25^{\circ}}=11.8310079158\approx \boxed{11.83}$

$\frac{a}{\sin 65^{\circ}}=\frac{5}{\sin25^{\circ}},\\a=\frac{5\sin 65^{\circ}}{\sin25^{\circ}}=10.7225346025\approx \boxed{10.72}$

Which table of ordered pairs represents a function?

Veronika [31]

Answer:

Graph on the top right.

Step-by-step explanation:

A function is a relation where one domain value is assigned to exactly one range value.

In a table, there would be no values repeating in the x-column.

The graph on the top right does not repeat any x values. Therefore, it is a function.

Why the other options are not functions:

The top left graph has 4 for all it's domain values.
The bottom left graph has '-2' repeating for the domain.
The graph on the bottom right repeats '0' as the domain.

Hope this helps.

Answer:

$\frac{15,7 - 20}{1,26} = - 3,4$

Step-by-step explanation:

To determine the Z - score, it is calculated as follows:

$\frac{X - X_{avg} }{σ}$

Then:

$\frac{15,7 - 20}{1,26} = - 3,4$

It means that there are more than 3 standar deviations below the advertised mileage.
