1 2/3 divided by 3/16

5/3 / 3/16

KCF (Keep, Change, Flip)

5/3 * 16/3

5 * 16 = 80

3 * 3 = 9

5/3 * 16/3 = 80/9

8 8/9

Hope this helps!

Answer:

80/9

Step-by-step explanation:

Step 1: Convert 1 2/3 into the improper fraction 5/3.

Step 2: Invert the divisor fraction, 3/16, and use the result (16/3) as a multiplier instead:

5 16

----* ----- = 80/9

What is the surface area of the figure?<br> 240<br> 48<br> 192

Ulleksa [173]

Answer:

240 cm²

Step-by-step explanation:

We are required to determine the surface area of the figure;

To get the area we add the are of all the surfaces;

Area of triangle;

Area = 0.5 × b × h

There are two triangles;

Therefore;

Area of the two triangles;

Area = 0.5 × 6 × 8 × 2

= 48 cm²

Area of the rectangles;

Area of a rectangle = Length × width

Area of the first rectangle;

= 6 cm × 8 cm

= 48 cm²

Area of the second rectangle

= 8 cm × 8 cm

= 64 cm²

Area of the third rectangle

= 10 cm × 8 cm

= 80 cm²

The total surface area will be;

Area = 48 cm² + 48 cm² + 64 cm² + 80 cm²

= 240 cm²

The lengths of lumber a machine cuts are normally distributed with a mean of 106 inches and a standard deviation of 0.3 inch. (

Vinvika [58]

Answer:

a) $P(X>106.11)=P(\frac{X-\mu}{\sigma}\frac{106.11-106}{0.3})=P(z>0.37)$

And we can find this probability with the complement rule:

$P(z>0.37)=1-P(z$

b) $z =\frac{106.11- 106}{\frac{0.3}{\sqrt{44}}}= 2.431$

And if we use the z score we got:

$P(z>2.431) =1-P(z$

Step-by-step explanation:

Let X the random variable that represent the lengths of a population, and for this case we know the distribution for X is given by:

$X \sim N(106,0.3)$

Where $\mu=106$ and $\sigma=0.3$

Part a

We are interested on this probability

$P(X>106.11)$

And we can use the z score formula given by:

$z=\frac{x-\mu}{\sigma}$

And using this formula we got:

$P(X>106.11)=P(\frac{X-\mu}{\sigma}\frac{106.11-106}{0.3})=P(z>0.37)$

And we can find this probability with the complement rule:

$P(z>0.37)=1-P(z$

Part b

For this case we select a sample of n =44 and the new z score formula is given by:

$z=\frac{x-\mu}{\frac{\sigma}{\sqrt{n}}}$

And if we find the z score we got:

$z =\frac{106.11- 106}{\frac{0.3}{\sqrt{44}}}= 2.431$

And if we use the z score we got:

$P(z>2.431) =1-P(z$
