Answer:

<em>Probability point lies on shaded region: ( About ) 0.294</em>

Step-by-step explanation:

<em>~ If we are to find the probability, we must find the area of the shaded figure, over that of the total area of this trapezoid ( whole figure ) ~</em>

Let us get the general dimensions. Firstly, the base of the trapezoid is composed of parts 5, 12, and 5. This is an isoceles trapezoid, meaning that the triangles ( shaded region )  are congruent to one another, including the altitudes. That would mean the non - shaded region is a parallelogram, provided altitudes are congruent and by definition of a trapezoid the bases are congruent.

1. Given the information above, the smaller base is congruent to the opposite side of the parallelogram created, so it is 12 units in length, the larger base being 12 + 5 + 5 ⇒ 22 units

2. By Pythagorean Theorem, if x ⇒ altitude of one of the triangles ( shaded region), 5^2 + x^2 = 13^2 ⇒ 25 + x^2 = 169 ⇒ x^2 = 144 ⇒ altitude = 12 units

3. Now we can find the area of this trapezoid by:  ( base + base/2 ) * altitude ⇒ ( 12 + 22 / 2 ) * 12 ⇒ ( 34 / 2 ) * 12 ⇒ ( 17 ) * 12 ⇒ 204 units^2

5. The shaded region is composed of two triangles, and knowing the triangles are ≅, let us solve for the area of one triangle and multiply that by 2 to find the total area of the shaded region. Area of triangle: 1/2 * base * altitude ⇒ 1/2 * 5 * 12 ⇒ 30 units^2. Area of shaded region: 30 * 2 = 60 units^2

<em>Probability point lies on shaded region: 60/204 ⇒ ( About ) 0.294</em>

The probability of a chance event is anumber between blank that expresses the likelihood that an event blank occur
Mademuasel [1]

The statements second, Third and Fifth are correct statement related probabilities. which represent the 0.25 indicates an unlikely event and

0.75 indicates a likely event and 0.5 indicates equally likely to occur or not occur.

According to the statement

we have given that the some points related the probability and we ahve to express the correct statement and explain them.

So, We know that the

Probability is a the chance that a given event will occur.

And we know that the

  • A zero probability (0) means that the event is impossible, it will never happen.
  • A one probability (1) means that the event will occur with certainty.

You might split the likelihood in some notorious outcomes:

0: impossible (the event will never happen)

Close to zero (about 0 - 0.3): unlikely (the chances are small)

0.5: even (equal chances of happening and not happening)

Close to 1 (about 0.7 - 1): likely (the changes are large)

1: certain (it is 100% sure that the event will happen)

This means that:

first statement, 0 indicates a certain event, is incorrect.

0.25 indicates an unlikely event (second statement is correct)

0.75 indicates a likely event (third statement is correct)

fourth statement is incorrect (1 does not indicate an impossible event, but a certain event)

0.5 indicates equally likely to occur or not occur (fith statement is correct).

So, The statements second, Third and Fifth are correct statement related probabilities. which represent the 0.25 indicates an unlikely event and

0.75 indicates a likely event and 0.5 indicates equally likely to occur or not occur.

Question:

Given that the Probability of a chance event is a number between zero and one that expresses the likelihood of the event occurring, choose all that are correct.

•0 indicates a certain event

•0.25 indicates an unlikely event

•0.75 indicates a likely event

•1 indicates an impossible event

•0.5 indicates equally likely to occur or not occur.

Matthew purchased a desk that was on sale for 45% off the orginal price of $480.If the sales tax was 8% (of the sale price), how
Yanka [14]

Answer:

285.12

Step-by-step explanation:

discount amount = 45/100 x 480= 45x48/10

=216.0

price after discount= 480-216=264

sales tax= 8/100 x 264=21.12

total money spent = 264+21.12=285.12
