The answer is 43.5 because you add all of them then divide by 25
Answer:
(x-4)*(x+5) : x =4,-5
Step-by-step explanation:
a= 1
b= 1
c= -20
x1,2 = (-1+-(1 - (4*1*-20))^0.5)/2
x1,2 = (-1+-(1+80)^0.5)/2
x1,2 = (-1+-(81^0.5))/2
x1,2 =(-1+-9)/2
x1 = 8/2 = 4 x2 = -10/2 = -5
When it has a slope of 3 it means y=3x+k
Given the condition that f(-2)=0
So,replace the y with 0 and x with -2
0=3*-2+k
0=-6+k
k=6
So the line is y=3x+6
when f(p)=3,
3x+6=3
3x=-3
X=-1
So,
p=-1
Answer:
Mode- yellow
Number of 2nd graders- 17
Step-by-step explanation:
The mode is the variable with the largest value.
Yellow is the mode because the most students voted for it.
To find the number of 2nd graders, add up all of the dots.
1 + 3 + 4 + 6 + 3 = 17
There are 17 students
Answer: one answer.
