Answer:
If i am correct,
f(4) = -8
g(-3) = 39
Step-by-step explanation:
Answer:
x=3 x = -8
Step-by-step explanation:
f(x) = (x-3)(x+8)
To find the zeros, set the equation equal to zero
0 = (x-3)(x+8)
Using the zero product property
0=x-3 0 = x+8
x=3 x = -8
Answer:
the mode is 7 because they have the most points
Step-by-step explanation:
Answer:
0.353
Step-by-step explanation:
We have been given that a history class is comprised of 7 female and 10 male students.
We will use combinations to solve our problem.
We can choose 6 female students out of 7 female students in ways.
We can choose 7 male students out of 10 male students in ways.
So the number of ways that 6 female and 7 males can be chose is: 7*120 = 840.
Now let us find ways in which 13 students can be chosen from 17 students as:
Now let us substitute our values in probability formula.
Therefore, the probability of selecting 6 female students and 7 male students is 0.353.
Work in rates per hour. These rates can then be added to form an equation
1/13 + 1/10 = 1/x where x is the time for both working together
multiply thru by 130x:-
10 x+ 13 x = 130
x = 130/23 = 5.65 hours or about 6 hours 39 minutes
