Let x be a random variable representing the mean saraly of professors at two year institutions, then
P(x > 55000) = 1 - P(z < (55000 - 52500)/4000) = 1 - P(z < 0.625) = 1 - 0.73401 = 0.26599
Answer:
11%
Step-by-step explanation:
0.11*100=11%

Hey there!
A proportion is when two ratios are equal in terms of value.
Thank you! :D
Answer:
a) 2
b) -2
c) -2
d) 1/2
Step-by-step explanation:
1) f(-4) means that x=-4 and you must locate the y value on the graph
2) f(2) means that x=2 and you must locate the y value on the graph
3) f(x)=4 means that y=4 and you must locate the x value on the graph
4) f(x)=-1 means that y=-1 and you must locate the x value on the graph
The gradient of a line depends on how steep it is. The gradient of y=1/3x is 1/3 so you can use any other number that is higher than 1/3 eg y=2
