10 4/5 - 3 1/2 = 7.3

7.3 = 73/10

73/10 simplified:

7 3/10

10 4/5 - 3 1/2 = 7 3/10

The volume of the plastic cylinder is 64. A glass cylinder has the same height and radius is half of the plastic cylinder radius

sp2606 [1]

Answer:

I am not sure if I'm correct, but I got 16

Step-by-step explanation:

lets look at the formula for cylinder volume:

V=π*r^(2)*h

now, lets plug in 64

64=π*r^(2)*h

h=64/(π*r^(2))

Volume of glass cylinder is

V=((0.5r)^2)*(64/(π*r^(2)))*π

V=0.25π*r^(2)*(64/(π*r^(2)))

V=16π*r^(2)/(π*r^(2)

V=16

If sin=3/5 then what cos equal to

kap26 [50]

$\sin {}^{2} ( \alpha ) + \cos {}^{2} ( \alpha ) = 1$
$\frac{9}{25} + \cos {}^{2} ( \alpha ) = 1$
$\cos {}^{2} ( \alpha ) = \frac{16}{25}$
$\cos( \alpha ) = \frac{4}{5}$

In an experiment Tom drops 12 drawing pins onto a hard floor. He does the experiment 10 times and counts how many pins land 'poi

Phoenix [80]

Answer:

a) 0.35

b) 420 drawing pins

Step-by-step explanation:

a) The question relates to the relative frequency of the pins pointing up which is found by the formula as follows;

$Relative \ frequency = \dfrac{Number \ of \ successful \ trials }{Total \ number \ of \ trials}$

The total number of pins land 'point up' = 3 + 5 + 6 + 2 + 4 + 7 + 3 + 3 + 4 + 5

The total number of pins land 'point up' = 42 successful trials

Total number of trials = 12 × 10 = 120 trials

$Relative \ frequency = \dfrac{42 }{120}= \dfrac{7}{20}$

Due to the large number of trials, the relative frequency ≈ Probability and the probability that a single pin will land point up = 7/20 = 0.35

b) Given that the number of trials now = 12 × 100 = 1200, we have;

The expected number of drawing pins in total that would land point up = 0.35×1200 = 420 pins.
