Answer:
x=30
Step-by-step explanation:
53+97+x=180
150+x=180
x=30
Answer: 
Step-by-step explanation:
Given, A class has five boys and nine girls.
Total students = 5+9=14
Number of ways to choose 6 students out of 14=
[Using combinations]
Number of ways to choose 4 girls out of 6 (4 girls + 2 boys = 6 ) = 
If the teacher randomly picks six students, then the probability that he will pick exactly four girls:-


hence, the required probability =
.
B: Negative 9 and 3 over 6
Answer:
Approximately 5.26%
Step-by-step explanation:
180 is 94.74% of 190 so, to find the percentage LOST 100 - 94.74 ≈ 5.26%
The domain will be the numbers you can use for x and not get a
undefined thing like division by 0 or square root of a negative number
(f*g)(x)=f(x) times g(x)=(3x+2) times (7x+6)=(3x+2)(7x+6)=

the domain is all real numbers because we can't find any values of x that make a division by 0 or square root of a negative
answer is C
