Answer:

3 quarters 9 dimes

Step-by-step explanation:

D=dimes

D-6=quarters

0.10 D + 0.25(D-6) = 1.65

0.10D + 0.25D - 1.5 = 1.65

0.35D = 3.15

Dibide both sides by 0.35

D =9

Q= D-6 Q = 9-6 Q=3

9*0.10 =90 3*0.25= 0.75

$0.75 + $0.90 =$ 1.65

LiRa [457]

Answer:

The correct answer is "0.9332".

Step-by-step explanation:

Given that:

$\mu=12.30$

$\sigma=0.20$

So,

= $P(X>12)$

= $1-P(X$

= $1-P(\frac{X-\mu}{\sigma} < \frac{12-12.30}{0.20} )$

= $1-P(Z$

= $1-0.0668$

= $0.9332$
