t=0.21
Step-by-step explanation:
Given
and a population mean
.
#We state our hypothesis as:

The evidence available should validate either the null or alternative hypothesis.
#We calculate the test statistic as:


Hence, the test statistic is t=0.21
Answer:
Hence after solving the given equation we get <em>x = 13/20.</em>
Step-by-step explanation:
<em>Given:</em>
<em>-3 x + 0.1 + 10 x = x + 4</em>
<em>-3 x + 10 x - x = 4 - 0.1</em>
<em>6 x = 3.9</em>
<em> x =
</em>
<em>x =
</em>
<em>x =
</em>
Answer:
(2x-3)(x+1)
Step-by-step explanation:
