Answer:
Step-by-step explanation:
Using a graphing calculator, plot (x,y) points
- x = no. of jobs
- y = no. of workers needed
and plot the functions from the options to know which function fits the data
The x which achieve these statement is x=0.
The variable y is given.
now, substitute y in the second equation to get
-4x - (-4x-7) = 7
then we solve
first distribute
-4x+4x+7=7
combine like terms
0+7 = 7
7 = 7
because the answer is true, the solution to this system is “all real numbers”
Answer:
0.15
Step-by-step explanation:
The relative frequency for FAIL is
The number of times failed occurred/ The number of times the experiment was conducted.
Which is ;
60/400= 0.15
On a side note that relative value of success given is wrong; typo error probably. It should be 0.61
