A musical instrument has a pitch of 220 hertz when the wavelength is 3 feet. When the wavelength is 4 feet, the pitch is 165 her
earnstyle [38]
We know that
Inverse Variation is a<span> relationship between two variables in which the product is a constant
so
let
x------> a pitch of a musical instrument
y------> </span><span>the wavelength
x*y=k

find the value of k

for x=</span><span>220 hertz   y=3 ft
</span><span>x*y=k
220*3=k
k=660

</span>for x=165 hertz   y=4 ft
x*y=k
165*4=660
k=660<span>

the answer part a) is
</span><span>the type of variation between pitch and wavelength is an inverse variation
</span>
part b) <span>What is the pitch when the wavelength is 5 feet?
x=?
y=5 ft
k=660
x*y=k------> solve for x
x=k/y----------> x=660/5-----> x=132 hertz

the answer Part b) is
132 hertz</span>

in a roulette wheel there are 38 numbered slots: 36 slots are the numbers 1 through 36 and the remaining two slots are 0 and 00.
frez [133]

roulette consists in placing a small ball in a roulette wheel, Probability (Roulette ball not landing on red) = 10 / 19

The probability of an event can be calculated by probability formula by simply dividing the favorable number of outcomes by the total number of possible outcomes

Given:

Number of total slots = 38

Number of red slots = 18

Number of black slots = 18

Number of green slots = 2

Find:

Probability (Roulette ball not landing on red)

Computation:

Probability (Roulette ball not landing on red) = 1 - Probability (Roulette ball landing on red)

Probability (Roulette ball not landing on red) = 1 - (18 / 38)

Probability (Roulette ball not landing on red) = 20 / 38

Probability (Roulette ball not landing on red) = 10 / 19

Answer:

All I know

Step-by-step explanation:All I know is that you have to distribute the top so 5{2k - 3} so that would be 10k-15 and then -3{k+4} would be -3k -12 hopefully this helps you out a littble bit so the top completely is 7k-27
