Hello! our answer here is going to be:
43.
Lets understand this a little better!
when dealing with exponents, it is the base number (3) times its self how ever many the above number is (3 again)
so, it wont be 3 x 3, but instead 3 x 3 x 3 because that's how much the exponent is.
same rule applies with 4^2!
Answer:
divide by 5: x = 13/5 = 2.6
Step-by-step explanation:
Make use of the properties of the multiplicative inverse and the multiplication identity element. Multiplying both sides of the equation by the multiplicative inverse of the coefficient of x makes the result be 1x on the left side.
(1/5)(5x) = (1/5)(13)
1x = 13/5
The multiplicative identity element (1) does not change the value of what it multiplies, so this simplifies to ...
x = 13/5
_____
Effectively, we divide (both sides) by 5.
The lowest must be ,,,,,when x=0
so
10y+30=0
10y=-30
y=-3
So your answer is (0, -3)
Answer:
And we are 9% confidence that the true mean for the difference of the population means is given by:
Step-by-step explanation:
For this problem we have the following data given:
represent the sample mean for one of the departments
represent the sample mean for the other department
represent the sample size for the first group
represent the sample size for the second group
represent the deviation for the first group
represent the deviation for the second group
Confidence interval
The confidence interval for the difference in the true means is given by:
The confidence given is 95% or 9.5, then the significance level is and . The degrees of freedom are given by:
And the critical value for this case is
And replacing we got:
And we are 9% confidence that the true mean for the difference of the population means is given by:
The given number is 0.555 which can be written as
As we see that after decimal, every next digit is 1/10 times of the current digit .
Therefore the statement , " the value of the 5 in the thousands place is ten times as great as the 5 in the hundredth place " is not correct .
