Answer:
-3
Step-by-step explanation:
2x-1=4x+5
-1=2x+5
-6=2x
x=-3
5 1/6 - 2 2/3
convert to improper fractions:
5 1/6 = 31/6
2 2/3 = 8/3
find common denominator:
8/3 = 16/6
31/6 - 16/6 = 15/6
15/6 = 2 3/6 = 2 1/2
<span>Null Hypothesis:µ equals 2.5Alternative Hypothesis:
µ not equal to 2.5
Z Test
Test Statistic, Ztest: -18.1912
Critical Zcritical: ±1.9607
P-Value: 0,0000
As Ztest is not within the limits of Zcritical we can reject the null hypothesis
95% Confidence interval:
2.495746 < µ < 2.496574</span>
It would be 12 x 3. This is because 4 x 3 is 12. He wants to triple the area. Multiply 12 by 3= 36. Hope it helps.
The answer is option C because |x| can never equal a negative number.
Hope I didn't mess up for your sake!
