Sandra bought 30 T-shirts at the clothing store. 20% of the T-shirts were blue and half of the T-shirts were black. How many of
insens350 [35]
So you have 20% of blue and 50% of black.
So you have 70% in total that are both blue and black.
100%- 70%= 30%
So that means 30% were neither blue or black.
Do a proportion
30/100= x/30
30 x 30= 900
900 divided by 100= 9
Answer is 9 shirts are neither blue or black

The measurement of the radius of the end of a log is found to be 9 inches, with a possible error of 1/2 inch. Use differentials
enot [183]

Answer:

\pm 9in^2

Step-by-step explanation:

We are given that

Radius of end of a log, r= 9 in

Error, \Delta r=\pm 1/2in

We have to find the error in computing the area of the end of the log by using differential.

Area of end of the log, A=pi r^2

\frac{dA}{dr}=2\pi r

\frac{dA}{dr}=2\pi (9)=18\pi in^2

Now,

Approximate error in area

dA=\frac{dA}{dr}(\Delta r)

Using the values

dA=18\pi (\pm 1/2)

\Delta A\approx dA=\pm 9in^2

Hence, the possible propagated error in computing the area of the end of the log=\pm 9in^2
