Y=mx+b
y= y axis
x= x axis
b= y intercept
m= slope
Answer:
Sample size = n = 37
Now we are supposed to find that the mean number of calls per salesperson per week is more than 42?
Since n > 30 so we will use z test
Formula :
Substitute the values
Z value at 0.100 is 1.64
Since the calculated z value is greater than the defined z value
So, we accept the null hypothesis
Hence we conclude that the mean number of calls per salesperson per week is not more than 42
Answer:
s = 13 - x
t =
Step-by-step explanation:
To start out with:
s = 18
t = 18
Sue gives Tony x sweets
s = 18 - x
t = 18 + x
Sue then eats 5 of her sweets
s = 18 - x - 5 = 13 - x
t = 18 + x
Tony eats half of his sweets
s = 13 - x
t =
(Possible constraint that )
Answer:
-3 < x < 1 or x > 6
