Answer:
<h2>x = 3.1</h2>Step-by-step explanation:
<h3><u>To solve first take logarithm to both sides</u>
That's
<h3>But
<h3>So we have
<u>Write 1200 as a number with the factor 100</u>
That's
1200 = 100 × 12
So we have
<h3><u>Using the rules of logarithms</u>
That's
<h3>Rewrite the expression
That's
<h3>x = 3.079

<h3>x = 3.1 to one decimal place</h3>Hope this helps you
For some value of z, the value of the cumulative standardized normal distribution is 0.8340. the value of z is
Answer: We are required to find the value of z corresponding to probability 0.8340.
i.e.,
We can find the value of z using the standard normal table.
Using the standard normal table, we have:
Therefore, for the value of z = 0.97, cumulative standardized normal distribution is 0.8340
