Answer:
x = 70
Step-by-step explanation:
Since 2 sides are equal then the triangle is isosceles with 2 congruent base angles , then
x = = = 70
If the remaining 4 letters can be anything, you have 2*26^4 = 913,952 possible 5-letter ham radio call signs.

Check Explanation
Step-by-step explanation:
A) The null hypothesis would be that the proportion of newly hired candidates that are not white is not significantly different from the proportion of the applicants that are not white & there is no significant evidence that the company's hiring practices are discriminatory.
Mathematically,
H₀: μ₀ = 0.53
And the alternative hypothesis would be that there is a significant difference between the proportion of newly hired candidates that are not white is not significantly different from the proportion of the applicants that are not white. More specifically, that the proportion of newly hired candidates that are not white is significantly less than the proportion of applicants that are not white & there is significant evidence that the company's hiring practices are indeed discriminatory.
Mathematically,
Hₐ: μ₀ < 0.53
B) The two errors that can come up in this hypothesis testing include -
Type I error: We reject the null hypothesis because we obtain that the proportion of newly hired candidates that are not white is significantly less than the proportion of applicants that are not white and conclude that there is indeed significant evidence that the company's hiring practices are discriminatory when in reality, there is no significant difference and hence, no discrimination.
Type II error: We accept the null hypothesis (fail to reject the null hypothesis) because we obtained that there is no significant difference between the proportion of newly hired candidates that are not white & th proportion of applicants that are not white and conclude that there is no discrimination in the company's hiring practices when in reality, there is significant difference in the stated proportions above and significant evidence that there is indeed significant evidence that the company's hiring practices are discriminatory.
C) The power of the test increases as the significance level reduces. This is because t-statistic increases as significance level reduces.
D) The standard error of the mean used in computing the t-score is given as
σₓ = (σ/√n)
It is evident that as the value of n increases, the standard error reduces and this widens the effect of the test, hence, the power of the test increases.

Alright. If a slope is negative it is going from right to left, the slope is -1/2 which means the slope is going up -1/2 and to the side -1. Also, the y-intercept is 4, which means the slope runs through the point (0,4). lets put this into the slope equation:
y=mx+b
y = -1/2x + 4
where m = slope
b = y-intercept.
If another line is running parallel, then it will have the same slope but a different y-intercept. Since the other line running parallel runs through the points (1, -5), it means that the y-intercept for this equation is -5.
y = -1/2x + 11/2
Last, a line running perpendicular will simply be the reciprocal of the line it is perpendicular to. Therefore the equation of the line perpendicular to the first line is
y = 2x + 12
