Answer:
1 or 100%.
Step-by-step explanation:
The probability of rolling less than 7 is equal to the probability of rolling 1 or 2 or 3 or 4 or 5 or 6. That is 1/6 + 1/6 + 1/6 + 1/6 + 1/6 + 1/6 = 6/6. So any number from the dice can come up when you roll it because a perfect dice has 6 sides.

Answer:
The value of the test statistic and degrees of freedom is 2.148 and 11 respectively.
Step-by-step explanation:
Consider the provided information.
The mean annual tuition and fees for a sample of 12 private colleges was 36,800 with a standard deviation of 5,000 .
Thus, n = 12, 
σ = 5000
degrees of freedom = n-1 = 12-1 = 11
Formula to find the value of z is: 
Where 
is mean of sample, μ is the mean of population, σ is the standard deviation of population and n is number of observations.
Hence, the value of the test statistic and degrees of freedom is 2.148 and 11 respectively.
Answer:1/2b^2
Step-by-step explanation: The square is b^2?
5x-10x+ 2(3y-2)= 10y-5x + 4
Multiply 2 x 3y and by -2
5x-10x+6y-4=10y-5x+4
You get 6y-4
-5x+6y-4=10y-5x+4
Subtract 10x from 5x to get -5x
6y-4=10y+4
Add 5x to the -5x
6y=10y+8
Add 4 to the other side to get 8
-4y=8
Subtract 6y-10y to get -4y
-4y/-4=8/-4
Divide -4y and 8 by -4 to get y by itself and -2
Y=-2
