Answers

Answer 1

1. The experts reported being 80 percent confident in their predictions.

2. The specific value of X, we cannot determine the extent to which the experts' predictions matched the reality.

This means that the experts believed their predictions had an 80 percent chance of being correct.

2. In reality, only X percent of the predictions were correct.

Let's assume the value of X is provided.

If the experts reported being 80 percent confident in their predictions, it means that out of all the predictions they made, they expected approximately 80 percent of them to be correct.

However, if in reality, only X percent of the predictions were correct, it indicates that the actual outcome differed from what the experts expected.

To evaluate the experts' accuracy, we can compare the expected success rate (80 percent) with the actual success rate (X percent). If X is higher than 80 percent, it suggests that the experts performed better than expected. Conversely, if X is lower than 80 percent, it implies that the experts' predictions were less accurate than they anticipated.

Without knowing the specific value of X, we cannot determine the extent to which the experts' predictions matched the reality.

Answers

Diego travelled x miles in the cab. To find out how far Diego travelled in the cab, we need to use the information given. We know that City Cabs charges a pickup fee of $ and $ per mile travelled.

Let's assume that Diego traveled x miles in the cab. The fare for the ride would be the pickup fee plus the cost per mile multiplied by the number of miles traveled. This can be represented as follows:

Fare = Pickup fee + (Cost per mile * Miles traveled)

Since we know that Diego's fare for the ride is $, we can set up the equation as:

$ = $ + ($ * x)

To solve for x, we can simplify the equation:

$ = $ + $x

$ - $ = $x

Divide both sides of the equation by $ to isolate x:

x = ($ - $) / $

Now, we can substitute the values given in the question to find the distance travelled:

x = ($ - $) / $

x = ($ - $) / $

x = ($ - $) / $

x = ($ - $) / $

Therefore, Diego travelled x miles in the cab.
