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

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

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

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

= $0.196$

How can you write (x-3)(x+4)-18 as a product of two binomials? Please show work please help

ANEK [815]

Answer:

OPTION C: (x - 5)(x + 6)

Step-by-step explanation:

Given: (x - 3)(x + 4) - 18

Product of (x - 3) and (x + 4) = x² + 4x - 3x - 12

Therefore, (x - 3)(x + 4) - 18 = x² + x - 30

This is a quadratic equation and the roots are x = 5, -6.

This can be written as binomials as:

(x - 5)(x + 6) which is the required answer.

So, OPTION C is the answer.
