Answer:

The number of blocks Serena walks from the school to the supermarket is  x × 5 blocks

Step-by-step explanation:

The question asks the number of blocks Serena walks from the school to the supermarket

The location of Serena's school is on the 14th street and the location of the super market is on the 9th street, therefore the number of blocks Serena walks from her school to the super market is given as follows;

Number of street between Serena's school and the super market = 14 - 9 = 5 streets

Number of blocks street each street = x blocks

Number of blocks Serena walks = x × 5 blocks.

Suppose you have the following information. 12% of all drivers do not have a valid driver’s license, 6% of all drivers have no i
lubasha [3.4K]

Answer:

e) 0.14

Step-by-step explanation:

We solve this problem building the Venn's diagram of these probabilities.

I am going to say that:

A is the probability that a driver does not have a valid driver's license.

B is the probability that a driver does not have insurance.

We have that:

A = a + (A \cap B)

In which a is the probability that a driver does not have a valid driver's license but has insurance and A \cap B is the probability that a driver does not have any of these things.

By the same logic, we have that:

B = b + (A \cap B)

We start finding these values from the intersection.

4% have neither

This means that (A \cap B) = 0.04

6% of all drivers have no insurance

This means that B = 0.06. So

B = b + (A \cap B)

0.06 = b + 0.04

b = 0.02

12% of all drivers do not have a valid driver’s license

This means that A = 0.12

So

A = a + (A \cap B)

0.12 = a + 0.04

a = 0.08

The probability that a randomly selected driver either fails to have a valid license or fails to have insurance is about

P = a + b + (A \cap B) = 0.08 + 0.02 + 0.04 = 0.14

So the correct answer is:

e) 0.14

Perform the indicated operation. (-18)/-(4)
Illusion [34]
A negative divided by a negative is always a positive. 4 can go into 18 only 4 times to get 16 with a remainder of 2. 2 is half of four, therefore -4 can go into -18 4.5 times. 
The answer is 4 1/2 or 4.5.
I hope this helps ^-^
