Answer:
b = (a - 6)/V
Step-by-step explanation:
a = Vb + 6
Subtract 6 from both sides:
a - 6 = Vb
b = (a - 6)/V
Your answer is $30,000.
The way I have answered this is quite strange, but I'll do my best to explain it. So because we know that $30,900 is 3% than last year, we can call it 103%. This allows us to form a ratio and therefore find 100%.
30,900 : 103
÷ 103
300 : 1
× 100
30,000 : 100
Which means $30,000 is 100%, or 3% less than $30,900. I hope this helps! Let me know if it was confusing or anything :)
Answer:
No the evidence is not sufficient
Step-by-step explanation:
From the question we are told that
The sample size is
The sample proportion is
The population proportion is
The Null hypothesis is
The Alternative hypothesis is
The level of significance is given as
The critical value for the level of significance is
Now the test statistic is mathematically evaluated as
substituting values
Since the critical value is greater than the test statistics then the Null hypothesis is rejected which there is no sufficient evidence to support the claim

Answer:
AC 4x + 16
Angle BEC is 72 degrees
Step-by-step explanation:
AE is 2x + 8, and AC is 2 times bigger, so 4x + 16
Angle EAD is the same as angle EDA, which is 54 degrees, a triangle has 3 sides measuring 180 degrees total, 54 + 54 = 108, so the last angle is 180 - 108 = 72, angle AED is 72, since angle BEC is the same as angle AED, it is also 72 degrees
