Answer:
The lower limit is 36
Upper limit is 96
Standard deviation is 30
Step-by-step explanation:
Considering the range of the test score which is 60. i.e the difference between the largest and the smallest number is 60. The mean is 66 which is a measure of central tendency. That is it is at the centre of the distribution. Dividing 60 by 2 gives 30.
Adding 30 to the mean will indicate our upper limit i.e 30+66=96
Also, subtracting 30 from 66 will give the lower limit i.e. 66-30=36
The Distance between the range and the mean is the standard deviation
Which in this case is +30 or -30
A is the answer because if it is 2.50 each day then the answer is 2.50d
Answer: 1. -7 -8 multiplied by -7 equals 56
Step-by-step explanation:
Answer:
-16 > n or n < -16
Step-by-step explanation:
First, we can write the inequality and distribute.
-6n-12 > 3(-n+12)
-6n-12 > -3n+36
Get rid of a variable first (it makes solving a lot easier). We can add 6n to both sides.
-6n-12 > -3n+36
<u>+6n +6n</u>
-12 > 3n+36
Now, we can subtract 36 on both sides.
-12 > 3n+36
<u>-36 -36</u>
-48 > 3n
Divide by 3 on both sides.
-48 > 3n
<u>/3 /3</u>
-16 > n or (if it's easier) n < -16
