Answer:
The 98% confidence interval for the difference of the mean amount of June precipitation in Michigan cities and Ohio cities is (-1.77, 0.29).
Step-by-step explanation:
The (1 - <em>α</em>)% confidence interval for the difference between two population mean is:
Compute the value of sample means and sample standard deviations from the provided data.
The critical value of <em>t</em> for 98% confidence level and (n - 1) = 4 degrees of freedom is:
Compute the 98% confidence interval for the difference of the mean amount of June precipitation in Michigan cities and Ohio cities as follows:
Thus, the 98% confidence interval for the difference of the mean amount of June precipitation in Michigan cities and Ohio cities is (-1.77, 0.29).
Answer: 49
to find g^-1 switch the x and y and solve for y
y = 1/7x - 1
x = 1/7y - 1
x + 1 = 1/7y
7(x+1) = y
g^-1 = 7(x+1)
g^-1 (6) = 7(6+1) = 7(7) = 49
In order for this to be true, 2x - 4 has to equal 2, because
㏒2 16 = 4
2x - 4 = 2
2x = 6
x = 3
Hope it helps!
It depends if x is positive or negative and the same as in y
The answer for this will be letter d. C = 22π and A = 121π. This is computed using the formula of C= Dπ which is C = (22)π. On the other hand, the area of this circle is computed by using the formula A = <span>πr^2. This is computed as follows:
A = </span><span>πr^2
A = </span><span>π (22/2)^2
A = </span><span>π (11)^2
</span>A = 121<span>π</span><span>
