Which expression is equivalent to -14 - 32d

All Seasons Plumbing has two service trucks that frequently need repair. If the probability the first truck is available is .75,

astra-53 [7]

Answer:

5% probability neither truck is available

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 the first truck is available.

B is the probability that the second truck is available.

We have that:

$A = a + (A \cap B)$

In which a is the probability that the first truck is available and the second one is not $A \cap B$ is the probability that both trucks are available.

By the same logic, we have that:

$B = b + (A \cap B)$

The probability that both trucks are available is .30.

This means that $A \cap B = 0.3$

The probability the second truck is available is .50

This means that $B = 0.5$ . So

$B = b + (A \cap B)$

$0.5 = b + 0.3$

$b = 0.2$

The probability the first truck is available is .75

This means that $A = 0.75$ . So

$A = a + (A \cap B)$

$0.75 = a + 0.3$

$a = 0.45$

The probability that at least one truck is available is:

$A \cup B = a + b + (A \cap B) = 0.45 + 0.2 + 0.3 = 0.95$

The probability that neither truck is available is:

$1 - (A \cup B) = 1 - 0.95 = 0.05$

5% probability neither truck is available

tensa zangetsu [6.8K]

Answer:

The least value plotted on the line plot is 18.0

The greatest value plotted on the line plot is 22.0

The height of inches occurs the most often is 19.5 with 3 times

Step-by-step explanation:

A line plot is a graph that shows frequency (the number of times the data value occurs) of data along a number line.

The line plot has dots plotted on it over each value of the number line.
