Answer: $25x^2-95x-20=5(5x^2-19x-4)=5(5x^2+x-20x-4)\n\n=5[x(5x+1)-4(5x+1)]=5(5x+1)(x-4)$

Answer 2

Answer: 25x²-95x-20
=5(5x²-19x-4)
=5(5x+1)(x-4) <- this is the final answer. :)

There are 200 students in the 7th grade class at Manchester Middle School. Of these students, 22% play football and 12% play baseball. Eight students play on both teams. What is the probability that a student plays either football or baseball?

Answers

Answer: There is 30% student plays either football or baseball.

Step-by-step explanation:

Since we have given that

Total number of students = 200

Percentage of students who play football = 22%

Number of students who play football n(F) is given by

$0.22* 200\n\n=44$

Percentage of students who play baseball = 12%

Number of students who play baseball n(B) is given by

$0.12* 200\n\n=24$

Number of students who play on both teams n(F∩B) = 8

According to rules, it becomes,

$n(F\cap B)=n(F)+n(B)-n(F\cap B)\n\nn(F\cap B)=44+24-8=60$

Probability that a student plays either football or baseball is given by

$(60)/(200)\n\n=0.3\n\n=30\%$

Hence, there is 30% student plays either football or baseball.
