By the third day of a particular week, 2 accidents have already occurred in the intersection. What is the probability that there

Leona [35]

Answer:

The right answer is "0.70".

Step-by-step explanation:

The given query seems to be incomplete. Please find below the attachment of the full query.

By using the Bayes' theorem, we get

⇒ $P[(X$

By putting the values, we get

$=\frac{[P(2)+P(3)]}{[1-P(0)-P(1)]}$

$=\frac{(0.20+0.15)}{1-0.20-0.30}$

$=\frac{0.35}{0.5}$

$=0.70$

A ball is thrown from a height of 49 meters with an initial downward velocity of 2 m/s. The ball's height (in meters) after t se

horsena [70]

The height of the ball at ground level would be 0 feet.

Set h to 0 and solve for t:

Rewrite the equation as

-5t^2 -2t +49 = 0

Factor -1 out of the equation to get:

5t^2 + 2t -49 = 0

Use the quadratic formula:

-b +/- sqrt(b^2 -4(ac) / 2a

Where a = 5, b = 2 and c = -49

The quadratic formula becomes:

-2 +/-sqrt(2^2 – 4(5*-49) / (2*5)

Simplify to get :

T = -2 +/-sqrt246 / 10

T = 2.936 and – 3.336

Since the time has to be a positive value t = 2.936 seconds.

Rounded to the nearest hundredth = 2.94 seconds.

Choose one of the theorems about chords of a circle and state it using your own words. Create a problem about chords that uses t

Mazyrski [523]

Answer:

Step-by-step explanation:

1. A given chord on a circle is perpendicular to a radius through its center, and it is at a distance less that the radius of the circle.

2. A circle of center O has a radius of 13 units. If a chord AB of 10 units is drawn at a distance, d, to the center of the circle, determine the value of d.

3. From question 2, the radius = 13 units, length of chord = 10 units and distance of chord to center of the circle is d.

A radius that meet the chord at center C, and divides it into two equal parts.

So that;

AC = CB = 5 units

Applying Pythagoras theorem to ΔOCB,

OC = d, CB = 5 units and OB = 13 units

$13^{2}$ = $5^{2}$ + $d^{2}$

169 = 25 + $d^{2}$

169 - 25 = $d^{2}$

144 = $d^{2}$

⇒ d = $\sqrt{144}$

= 12 units

Therefore, the chord is at a distance of 12 units to the center of the circle.

Many urban zoos are looking at ways to effectively handle animal waste. One zoo has installed a facility that will transform ani

Zolol [24]

Answer: The correct answer is (A).

Step-by-step explanation:

Let X = the amount of waste produced in a given day. X follows a distribution that is approximately Normal with a mean of 348.5 pounds and a standard deviation of 38.2 pounds.

P(X > 350) = Normalcdf(lower: 350, upper: 1000, mean: 348.5, SD: 38.2) = 0.484.
