mamaluj [8]

Answer:

a. 100 mph

b. 500 mph

Step-by-step explanation:

a.

Let the speed of Lindbergh's plane be x.

Today's planes are 5 times faster, so their speed is 5x.

Today's planes speed is 400 mph faster than Lindbergh's speed.

x + 400 = 5x

5x = x + 400

4x = 400

x = 100

Lindbergh's speed was 100 mph

b. 5x = 5 * 100 = 500

Today's planes fly at 500 mph

What are the solutions to the equation (x – 6)(x + 8) = 0?
Likurg_2 [28]
X=6 and x=-8

To solve this, you would treat x-6=0 as one equation, you add 6 to each side to get rid of -6, hence you would get x=6.

Same goes for x+8=0, subtract 8 from each side to get rid of the +8, then you get x=-8

Based on a study from the Chronicles of Flippin'' Awesomeness, the probability that Napoleon and Pedro make it to their first pe
muminat

Answer:

15.25% probability that Napoleon and Pedro catch the bus and make it to their first period class on time

Step-by-step explanation:

We use the conditional probability formula to solve this question. It is

P(B|A) = \frac{P(A \cap B)}{P(A)}

In which

P(B|A) is the probability of event B happening, given that A happened.

P(A \cap B) is the probability of both A and B happening.

P(A) is the probability of A happening.

In this problem, we have that:

Event A: Both Napoleon and Pedro catch the bus, so P(A) = 0.25.

Event B: Making to their first period class on time.

However, the probability that they make it to their first period class on time, given that they catch the bus is 0.61.

This means that P(B|A) = 0.61

What is the probability that Napoleon and Pedro catch the bus and make it to their first period class on time

P(B|A) = \frac{P(A \cap B)}{P(A)}

0.61 = \frac{P(A \cap B)}{0.25}

P(A \cap B) = 0.61*0.25

P(A \cap B) = 0.1525

15.25% probability that Napoleon and Pedro catch the bus and make it to their first period class on time
