Nastasia [14]

Answer:

Tax: $3.06

Step-by-step explanation:

7% of 43.75 = 0.07 × 43.75 = 3.0625

43.75 increase 7% =

43.75 × (1 + 7%) = 43.75 × (1 + 0.07) = 46.8125

Radio: $43.75

Tax: $3.06

Total: $46.81

Suppose that engineering specifications on the shelf depth of a certain slug to be turned on a CNC lathe are from .0275 in. to .

MrRa [10]

Answer:

0.8188 or 82%

0.0000643

Step-by-step explanation:

Given that engineering specifications on the shelf depth of a certain slug to be turned on a CNC lathe are from .0275 in. to .0278 in.

If x is the dimension then X is N(0.0276, 0.0001)

Or $\frac{x-0.0276}{0.0001}$ is Normal (0,1)

a) Fraction of shelf depths are in specifications

= $P(0.0275$

b) For 98% to be within the specifications,

$\mu = 0.02765$

Margin of error = $0.0278-0.02775\\=0.00015$

For 98% critical value Z two tailed is 2.33

Hence std error = $\frac{0.00015}{2.33} \\=0.0000643$

So sigma should be = 0.0000643
