5,25,125 find 10th term

anastassius [24]

Answer:

9765625

Step-by-step explanation:

There is a common ratio between consecutive terms , that is

r = 25 ÷ 5 = 125 ÷ 25 = 5

This indicates the sequence is geometric with n th term

$a_{n}$ = a₁ $r^{n-1}$

where a₁ is the first term and r the common ratio

Here a₁ = 5 and r = 5 , then

a₁₀ = 5 × $5^{9}$ = 5 × 1953125 = 9765625

g The manager of a grocery store has selected a random sample of 100 customers. The average length of time it took these 100 cus

vagabundo [1.1K]

Answer:

The right solution is "0.196".

Step-by-step explanation:

The given values are:

Standard deviation,

$\sigma=1 \ minute$

Sample size,

$n=100$

Confidence level,

$c=95$ %

$=0.95$

Now,

For $\alpha=1-c$

$= 1-0.95$

$=0.05$

then,

$Z_{\frac{\alpha}{2} } = Z_{\frac{0.05}{2} }$

$=Z_{0.025}$

$=1.96$

The margin or error will be:

⇒ $E=Z_{\frac{\alpha}{2} } (\frac{\sigma}{\sqrt{n} })$

On substituting the values, we get

= $1.96(\frac{1}{\sqrt{100} })$

= $1.96\times \frac{1}{10}$

= $0.196$
