What is a5 in the sequence defined as follows? an = 5x2^(n-1)

Mandarinka [93]

Given:

The nth term of the sequence is defined as $a_n=5\times 2^{n-1}$

We need to determine the term $a_5$ of the sequence.

The term $a_5$ :

The term $a_5$ can be determined by substituting n = 5 in the nth term of the sequence $a_n=5\times 2^{n-1}$

Thus, we get;

$a_5=5\times 2^{5-1}$

Simplifying the expression, we get;

$a_5=5\times 2^{4}$

Squaring the term, we have;

$a_5=5\times 16$

Multiplying the expression, we get;

$a_5=80$

Thus, the value of the term $a_5$ of the sequence is 80.

A consumer affairs investigator records the repair cost for 44 randomly selected TVs. A sample mean of $54.41$ 54.41 and standar

anzhelika [568]

Answer:

($47.245; $61.575)

Step-by-step explanation:

Mean sample repair cost (X) = $54.41

Standard deviation (s) = $28.89

Sample size (n) =44

Z-score for a 90% confidence interval (z) = 1.645

The confidence interval, assuming a normal distribution, is given by:

$X \pm z\frac{s}{\sqrt{n}}$

Applying the given data, the lower (L) and upper (U) bounds of the interval are:

$L=54.41-1.645*\frac{28.89}{\sqrt{44}} \\L=\$47.245\\U=54.41+1.645*\frac{28.89}{\sqrt{44}} \\U=\$61.575$

The confidence interval is I = ($47.245; $61.575)
