Answer:

3.2

Step-by-step explanation:

First, evalue what's inside of the absolute value:

3.1 + (-6.3) = -3.2

Now, since absolute value means the distance from the number to 0, the absolute value of -3.2 is the negation of -3.2:

|-3.2| = 3.2

kvasek [131]

Answer:0.614

Step-by-step explanation:

Given

Probability he will miss flight if it rains=0.06

Probability he will miss flight it does not rain=0.01

Given the probability of rain=0.21

Therefore Probability that it will not rain=1-0.21=0.79

Probability that he will miss the flight $=0.21\times 0.06+0.79\times 0.01=0.0205$

P(actual raining and he missed the flight| he miss the flight) $=\frac{0.21\times 0.06}{0.21\times 0.06+0.79\times 0.01}$

$=\frac{0.0126}{0.0205}=0.614$

When you add a percentage, you effectively multiply by the sum of 1 and that percentage. The same is true if the amount "added" is negative (as for a discounted price).

(original amount) + (percentage)×(original amount)

Use the distributive property to factor out the original amount:

= (original amount)×(1 + percentage)
