There are 5 cards less than nine that are prime, so there is a 5/9 chance of picking the first one prime. The second one would be 4/8 or 1/2, because you have removed a card from the deck. You multiply them together to get: 5/18. 

Hope this helps!

To find the quotient of 3 divided by one-sixtto find the quotient three-fourths divided by one-eighth,h, multiply 3 by
ollegr [7]

The quotient of 3 by 1/ 6 and that of 3/4 by 1/ 8 is 1/2 and 4 respectively

<h3>How to find the quotient</h3>

From the given equation, we have to find

= 3/4 ÷ 1/8

First , we take the denominator of the second fraction to be the numerator, we have

=

\frac{3}{4}  \times  \frac{8}{1}

Multiply through

=

\frac{24}{4}

=

6

To find the quotient of 3 by 1/6

=

3 \times  \frac{1}{6}

=

\frac{3}{6}

=

\frac{1}{2}

Thus, the quotient of 3 by 1/ 6 and that of 3/4 by 1/ 8 is 1/2 and 4 respectively

A barber’s chair with a person in it weighs 2118.0 N. The output plunger of a hydraulic system begins to lift the chair when the
liq [111]

Answer:5.8

Step-by-step explanation:

Given

weight of chair with person on it =2118 N

Barber applies a force of 63 N

Using pascal's law

we know pressure around both sides is equal

i.e. P_{chair}=P_{piston}

pressure=\frac{force}{area}

P_{chair}=\frac{2118}{\pi \dot r_{plunger}^2}

P_{piston}=\frac{63}{\pi \dot r_{piston}^2}

substituting values

\left [\frac{r_{plunger}^2}{r_{piston}^2}\right ]=\frac{2118}{63}

\left [\frac{r_{plunger}}{r_{piston}}\right ]=\left [ \frac{2118}{63}\right ]^{0.5}

\left [\frac{r_{plunger}}{r_{piston}}\right ]=5.798
