P->q is false and p is true.<br> q is<br> a.true<br> b.false

kirill [66]

Answer:

Choice b. $q$ has to be false.

Step-by-step explanation:

Consider the truth table of $p \implies q$ ( $p$ implies $q$ ).

$p$ is true and $q$ is true: $p \implies q$ would be true.
$p$ is true and $q$ is false: $p \implies q$ would be false.
$p$ is false and $q$ is true: $p \implies q$ would be true.
$p$ is false and $q$ is false: $p \implies q$ would also be true.

The only combination where $p \implies q$ is false is when $p$ is true and $q$ is false. Hence, the $q\!$ here must be false.

A survey of students at a university shows that 4 out of 5 drink coffee. Of the students who drink coffee, 1 out of 6 adds crea

Andru [333]

The number who drink coffee is 3/4 of 8000, so ...
... (3/4)×8000 = 6000.
Of those, 1/5 add cream, so the number of coffee drinkers who add cream to their coffee is ...
... (1/5)×6000 = 1200.
_____
Alternate solutions
We have computed ...
... (1/5)×((3/4)×8000) = 1200
Since multiplication is associative, you can multiply the fractions first, if you wish:
... ((1/5)×(3/4))×8000 = (3/20)×8000
... = 24000/20 = 1200
or
... = 3×(8000/20) = 3×400 = 1200
