A triangle can have sides of length 7, 9, and 18. true false

OleMash [197]

Answer:

That is false.

The sum of any two sides in a triangle must be greater than the length of the third side.

We can see that: 7+9 = 16, and 16 is not greater than 18.

So, this is not a triangle.

Let me know if this helps!

1) 16 = 8 Why is this wrong?

Dafna1 [17]

Step-by-step explanation:

This is wrong because it can be divided further by table of 8 4 or 2

So if we divide it by 8 the answer is

2 = 1

Now it cannot be divided further so this is the answer

Same is the answer if you divide it by 2 or 4

Inga [223]

Answer:

$P(GoodR/Below Forecast)= \frac{P(GoodR n Below Forecast)}{P(Below Forecast)}= \frac{0.02}{0.49} = 0.04$

Step-by-step explanation:

Hello!

Given the probability information about analyst's report (Good, Medium, and Bad) and the earnings announcement (Forecast), you have to calculate the probability that the analyst issued a good report, given that the earnings announcement was "bellow the forecast".

Symbolically: P(Good Report/Below Forecast)

This is a conditional probability, a little reminder:

If you have the events A and B, that are not independent, the probability of A given that B has already happened can be calculated as:

$P(A/B)= \frac{P(AnB)}{P(B)}$

Where P(A∩B) is the intersection between the two events and P(B) represents the marginal probability of ocurrence of B.

*-*

Using that formula:

$P(Good Report/Below Forecast)= \frac{P(Good Report n Below Forecast)}{P(Below Forecast)}$

As you can see you have to calculate the value of the probability for the intersection between "Good report" and "Below Forecast" and the probability for P(Below Forecast)

Using the given probability values you can clear the value of the intersection:

$P(BelowForecast/Good Report)= \frac{P(Good Report n Below Forecast)}{P(Good Report)}$

P(Good Report ∩ Below Forecast)= P(BelowForecast/GoodReport)*P(Good Report)= 0.1*0.2= 0.02

Now the probability of an earnings announcement being "Below Forecast" is marginal, that is if you were to arrange all possible outcomes in a contingency table this probability will be in the marginal sides of the table:

Below Forecast

Good Report P(GoodR∩BelowF)

Medium Report P(MediumR∩BelowF)

Bad Report P(BadR∩BelowF)

Total P(Below Forecast)

Then P(BelowF)=P(GoodR∩BelowF)+P(MediumR∩BelowF)+P(BadR∩BelowF)

You can clear the two missing probabilities from the remaining information:

$P(BelowForecast/MediumR)= \frac{P(BelowForecast n MediumR}{P(MediumR)}$

P(BelowF∩MediumR)= P(BelowF/MediumR)*P(MediumR)= 0.4*0.5= 0.2

$P(BelowForecast/BadR)= \frac{P(BelowForecastnBadR)}{P(BadR)}$

P(BelowF∩BadR)= P(BelowF/BadR)*P(BadR)= 0.9*0.3= 0.27

Now you can calculate the probability of the earning announcement being below forecast:

P(BelowF)=P(GoodR∩BelowF)+P(MediumR∩BelowF)+P(BadR∩BelowF)

P(BelowF)= 0.02+0.2+0.27= 0.49

And finally the asked probability is:

$P(GoodR/Below Forecast)= \frac{P(GoodR n Below Forecast)}{P(Below Forecast)}= \frac{0.02}{0.49} = 0.04$

I hope this helps!
