Answer:
m = 100, t = 80
Step-by-step explanation:
m + t = 180
6m + 8t = 1240
2x^2 + 5x + 2 = 0
(x + 2)(2x + 1) = 0
x = -2 x = - 1/2
Letter C
Total number of integers = 5
median
= (5+1)/2 th observation
= 3 rd observation
therefore the 3rd number = 13
now let the other number be x
total sum = 1+3+13+x+22 = 39+x
ATQ
(39+x)/5 = 16
39+x = 80
x = 41
the numbers are -
1,3,13,22,41
Answer:
a. 
Step-by-step explanation:
The given equation is;
To solve by the x-intercept method we need to graph the corresponding function using a graphing calculator or software.
The corresponding function is
The solution to is where the graph touches the x-axis.
We can see from the graph that; the x-intercepts are;
(-1,0),(3,0) and (6,0).
Therefore the real solutions are:
Answer:
2.5 minutes per quesiton
Step-by-step explanation:
75 minutes to take 30 quesitons means you divide the time equally so
