murzikaleks [220]

Answer:

The minimum IQ score will be "126".

Step-by-step explanation:

The given values are:

Mean

$\mu = 100$

Standard deviation

$\sigma=15$

Now,

⇒ $P(z>x)=4 \ percent \ i.e., 0.04$

⇒ $P(z>\frac{x- \mu}{\sigma} )=0.04$

⇒ $1-P(z \leq \frac{x-100}{15})=0.04$

⇒ $\frac{x-100}{15}=z0.96$

$=NORMDIS(z=0.96)$

$=1.751$

⇒ $x=100+15\times 1.751$

$=126.265 \ i.e., 126$

Hatshy [7]

Answer:

$\frac{x}{68,000}= \frac{27}{100}$

Step-by-step explanation:

Let

x ----> amount that Jethro owes in taxes

we know that

Amount that he made last year $\$68,000$

His tax rate $27\%=\frac{27}{100}$

Applying proportion

$\frac{x}{68,000}= \frac{27}{100}$

solve for x

$x=68,000(27)/100\\x=\$18,360$
