Answer:
b. 610, 50
Step-by-step explanation:
The mean score is the sum of all scores divided by the number of tests.
So if you increase the grade on each test, the mean will increase.
The standard deviation is the square root of the sum of the power of 2 of all scores subtracted by the mean(that is, the distance between each score and the mean) and divided by the number of tests.
As you increase each score by 10, the mean will change by 10. However, the distance between each score and the mean will stay the same, which means that the standard deviations remains unchanged.
In this problem, we have that:
Mean = 600
Standard deviation = 50
Scores increased by 10
So
Mean = 610
Standard deviation = 50
So the correct answer is:
b. 610, 50
Hi Ponie
Simplify both sides of the equation
3-x/5-4-x/2=1
3+ -1/5 x+ -4+ -1/2 x =1
Combine like terms
(-1/5 x + -1/2 x)+(3+-4)=1
-7/10 x +-1=1
-7/10 x -1=1
Add 1 to both sides
-7/10 x-1+1=1+1
-7/10 x=2
Multiply both sides by 10/-7
(10/-7)*(-7/10 x )= (10/-7)*2
x= -20/7
I hope that's help and I am sorry for the late answer !
Well if each set had 12 cards. So 18*12 = 216 :D

Hello,
Answer D
Step-by-step explanation:
Each value of the graph, y=f(x) is multiplied by 2
Red graph has for eqution y=2*f(x) or y/2=f(x)
I believe your answer should be $0.95
Of course, I could be wrong, and I apologise if I am.
