Answer: N=0
Step-by-step explanation:
0=−5n−2n
Rewrite the equation as −5n−2n=0. -5n−2n=0 S<em>ubtract 2n from −5n</em>. −7n=0 Divide each term by −7 and simplify.
Answer: 10/36
When a pair of fair dice are rolled , the total possible cases are (6 × 6) = 36. Out of these 36 cases the following 10 cases are favors(giving the sum > 8) for the happening of the event . These 10 cases are (3, 6), (4, 5), (4, 6),(5, 4), (5, 5), (5, 6) , (6, 3), (6, 4), (6, 5), & (6, 6)
Step-by-step explanation:
-10-2x = 3x+15
5x = -25
x= -5
Answer:
79.31%
Step-by-step explanation:
First we need to find the total number of students.
We do that summing all the four values in the table:
Total students = 2 + 18 + 3 + 6 = 29
Then, the students that play a sport or an instrument are all student but the ones that don't play both:
Students(sport or instrument) = 29 - 6 = 23
So the probability of a random student playing a sport or an instrument is 23/29 = 0.7931 = 79.31%
