Answer:
Sean earns $7.5 in each hour.
Step-by-step explanation:
Given:
Money earned by Sean = $300
Number of hours worked in a day = 8 hrs
Number of days of work in a week = 5
We need to find Money earned in each hour.
First we will find Total hours work in a week.
Total hours work in a week is equal to Number of hours worked in a day multiplied by number of days work in a week.
Framing in equation form we get;
Total hours worked in a week = 
Now we will find money earned for each hour.
Money earned each hour will be calculated by Dividing Total Money earned in a week by Total number of hours worked in a week.
Framing in equation form we get;
Money earned each hour = 
Hence Sean earns $7.5 in each hour.
Answer:
-2
Step-by-step explanation:
because it is tilted so z+4 +2 so -2+4=2
I'm a little unsure about this one, but I believe that scale factor is the rule that yields dilution, as it specifies how the diluted figure is placed on the graphing plane.
Answer:
Paired t test
H0 : μd = 0
H1 : μd > 0
Critical value = 3.499
Test statistic = 2.230
Reject H0 if test statistic > Critical value
Kindly check explanation.
Step-by-step explanation:
Given the data :
110 90 120 98 100 100 90 110
124 100 102 120 110 110 123 120
The hypothesis :
H0 : μd = 0
H1 : μd > 0
Tcritical value, df = n - 1 = 8 - 1 = 7
Tcritical(0.01, 7) = 3.499
The difference, d = (-14,-10,18,-22,-10,-10,-33,-10)
The test statistic :
Xdbar / Sd/√n
The mean difference, Xdbar = Σx / n = - 11.375
The standard deviation of difference, Sd = 14.431
The test statistic :
-11.375 / (14.431/√8) ;
-11.375 / 5.102
= 2.230
Decison :
Reject H0 if test statistic > Critical value
Since ; 2.230 <3.499 ;
We fail to reject the null
