A bag contains 33 red marbles, 6 white marbles, and 5 gray marbles. You randomly pick out a marble, record its color, and put it

Ksju [112]

<h3>Total 73 times we can expect white or gray marbles.</h3>

Step-by-step explanation:

Total number of marbles = 33

Number of white marbles = 6

Number of gray marbles = 5

Now, as we need to pick white or gray marbles, so favorable outcomes

= 6+ 5 = 11 marbles

Now, P(Picking out 1 white or gray marble) = $\frac{\textrm{Total Favorable outcomes}}{\textrm{Total Outcomes}} = \frac{11}{33} = (\frac{1}{3})$

Here, the same experiment is repeated 220 times.

So, the Combined Prediction

= Probability at first attempt x Number of repetitions

$= (\frac{1}{3} ) \times 220 = \frac{220}{3} = 73.33 \approx 73$

⇒The combined prediction after 220 attempts = 73

Hence, total 73 times we can expect white or gray marbles.

A parabola is graphed such that the axis of symmetry is x = 3. One of the x-intercepts is (5, 0). What is the other x-intercept?

Stells [14]

The axis of symmetry is the fold line that splits the parabola down the middle.

Now, since a parabola is symmetrical, every point, except the vertex, will have a mirror image of another point if we folded the parabola over the axis of symmetry.

So if we know the axis of symmetry is x = 3 and one of our points

has the coordinates (5, 0), the other point will have the coordinates (3, 0).

The axis of symmetry is always halfway between the x-intercepts.

We have two sides and one angle opposite to one of the known sides.

Begin with applying the Law of Sines to find angle A:
$\frac{sin A }{a}$ = <span> $\frac{sin C }{c}$

Then, solve for sin A:
</span>sin A = $\frac{a sinC}{c}$

Now, plug in numbers:
sin A = 19 × sin(38) / 10 = 1.17

We know that it does not exist an angle whose sin is bigger than 1, therefore
no triangle is formed.
