Answer: The answer is -1.
Step-by-step explanation: Given that 'a' and 'b' are integers such that their product is 5. We are to find the least possible value of 'a to the power b'.
Since a and b are integers and a × b = 5, so their possible values are
For these only four choices of a and b, we have the following values of a to the power b:
since -1 is the smallest among these four values, so the least possible value of 'a to the power b' is -1.
Thus, the answer is -1.
Answer:
i really dont know
Step-by-step explanation:
this is confusing
Distance formula = sqrt ((x2 - x1)^2 + (y2 - y1)^2)
(20,-4)...x1 = 20 and y1 = -4
(-4,3)...x2 = -4 and y2 = 3
now we sub
d = sqrt ((-4 - 20)^2 + (3 - (-4)^2)
d = sqrt ((-24^2) + (7^2))
d = sqrt (576 + 49)
d = sqrt 625
d = 25 <==
Answer:
The correct option is;
Step-by-step explanation:
Here we have the formula for the confidence interval of the difference of two means where the population standard deviation is unknown based on the sample mean and sample standard deviation is given as follows;
Where:
= Mean of the first sample = 22 grams
= Mean of the second sample = 18 grams
s₁ = Sample standard deviation of the first sample = 3.2 grams
s₂ = Sample standard deviation of the second sample = 2.1 grams
n₁ = Sample size of the first sample = 100
n₂ = Sample size of the second sample = 100
= t value obtained from tables at 99% confidence level and 100 degrees of freedom = 2.626 = 2.63
Therefore, plugging in the values, we have;
Therefore, the correct option is .
