k0ka [10]

Answer:

c) (40+60+25)/200 or 63%

Step-by-step explanation:

n= 200 students

Did Well on the Midterm and Studied for the Midterm = 75

Did Well on the Midterm and Went Partying = 40

Did Poorly on the Midterm and Studied for the Midterm = 25

Did Poorly on the Midterm and Went Partying = 60

The number of students that did poorly on the midterm or went partying the weekend before the midterm is given by the sum of all students who did poorly to all students who went partying minus the number of students who did Poorly on the Midterm and Went Partying:

$N=(25+60)+(40+60) - 60\\N= 125$

The probability that a randomly selected student did poorly on the midterm or went partying the weekend before the midterm is given by:

$P = \frac{N}{n}=\frac{125}{200} = 0.63 = 63\%$

How do you know that 5, 7, 8, 9, 10, and 11 are not factors of 12?

Mrrafil [7]

Answer :

Factors of 12 are

$1 \times 12 \\ 2 \times 6 \\ 3 \times 4.$

5 multiplied by any number can never give 12 . Multiples of 5 are
$5 \: 10 \: 15 \: 20$
7 multiples are
$7 \: 14 \: 21$
Same applies for all the listed numbers
