Answer: 525 cycles per second.
Step-by-step explanation:
The equation for inverse variation between x and y is given by :-
(1)
Given : The length of a violin string varies inversely with the frequency of its vibrations.
A violin string 14 inches long vibrates at a frequency of 450 cycles per second.
Let x = length of a violin
y= frequency of its vibrations
To find: The frequency of a 12 inch violin string.
Put 
in equation (1) , we get
Divide both sides by 12 , we get
Hence, the frequency of a 12 inch violin string = 525 cycles per second.
Ok so the P means probability and on the first one c is 1 of 3 of the total number of of letters in the spinner, and so is g
What that means is that they both have 1/3 probable chance of getting picked or 33.3% but it is most likely asking for a fraction so use 1/3
For 5 it’s more difficult
What you have to do is find the probability of heads and tails
Which is 1/2
D is 1/3
And the vowels are A and E which is 2/3
So you would multiply all the fractions and your answer would be ( work; 1/2 x 1/3 x2/3=) 1/18
Initial number of quarters; 6
x = number of days
Number of quarters added after x days: 2x
Total amount of quarters, y = 2x + 6
Note: the slope is 2 and the y-intercept is 6.

Answer:
The probability that the truck she selects will have at least one of the two features that Ella Stella wants is 50%.
Step-by-step explanation:
Since a certain store sells small, medium, and large toy trucks in each of the colors red, blue, green, and yellow, and the store has an equal number of trucks of each possible color / size combination, if Stella wants a medium red truck and her mother will randomly select one of the trucks in the store, to determine what is the probability that the truck she selects will have at least one of the two features that Stella wants, the following calculation must be performed:
3 sizes
4 colors
4 x 3 = 12
4 midsize cars
3 red cars
1 medium red car
4 + 3 - 1 = 6
6/12 = 0.5
Therefore, the probability that the truck she selects will have at least one of the two features that Ella Stella wants is 50%.
