Answer: F
Critical regions get smaller as α-values get smaller.
Explanation:
The figure below shows the critical regions (shaded) for a 2-tailed test at the 95% confidence level.
Because the total area under the curve is 1, the α-value is 1 - 0.95 = 0.05.
It is split up into 0.025 for a two-tailed test. It remains at 0.05 for a one-tailed test.
The critical z-score at 95% confidence level is z* = 1.96.
When the α-value decreases:
(a) the z* value increases,
(b) the confidence level increases,
(c) the critical region decreases.
Critical regions get smaller as α-values get smaller.

Answer:
B
Step-by-step explanation:
The secant- tangent angle b is half the difference of the measures of the intercepted arcs , then
b = ( 180 - 35) =
× 145° = 72.5° → B
The extraneous solution of the logarithmic problem is -4.
A log function is a way to find how much a number must be raised in order to get the desired number.
can be written as
where a is the base to which the power is to be raised,
b is the desired number that we want when power is to be raised,
c is the power that must be raised to a to get b.
Solving the function using the basic logarithmic value, we get,
If we solve further we will get that the value of x can be either -4 or 4, if take the value of x as -4, in the beginning then you will get log₃(18(-4)³) as the log of negative value which is impossible.
Hence, x=-4 is an extraneous solution.
