25.08 I think (the answer needs to be 20 characters long)
Answer:
D
Step-by-step explanation:
So first, we have to test the pairs. Let start with equation 1.
7=\=3 x
4=\=2 x
0=0 ✓
4=4 ✓
Now we only have to test B and D.
0=\=-1
4=4 ✓
D is the correct answer.
Answer:
There is not enough evidence to support the claim that Alaska had a lower proportion of identity theft than 23%.
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 1432
p = 23% = 0.23
Alpha, α = 0.05
Number of theft complaints , x = 321
First, we design the null and the alternate hypothesis
This is a one-tailed test.
Formula:
Putting the values, we get,
Now, we calculate the p-value from the table.
P-value = 0.298
Since the p-value is greater than the significance level, we fail to reject the null hypothesis and accept the null hypothesis.
Conclusion:
Thus, there is not enough evidence to support the claim that Alaska had a lower proportion of identity theft than 23%.
Answer:
x² - x - 12 = 0
Step-by-step explanation:
0 = -x² + x + 12
→ Add x² to both sides
x² = x + 12
→ Minus x from both sides
x² - x = 12
→ Minus 12 from both sides
x² - x - 12 = 0
