Answer:
25000m/s
Step-by-step explanation:
The following formula is used to calculate the speed or velocity of a wave.
V = f * w
Where V is the velocity (m/s)
f is the frequency (hz)
w is the wavelength (m)
First, determine the frequency.
Calculate the frequency of the wave.
Next, determine the wavelength.
Calculate the wavelength of the wave.
Finally, calculate the wave speed.
Using the formula above, calculate the wave speed.
Answer:
<h2>x = -4</h2>
Step-by-step explanation:
<em>Look a the picture</em>.
Draw the horizontal line <em>y = 2</em>.
Common point: (-4, 2).
Conclusion: f(x) = 2 → x = -4
Answer:
77.44%
49.87%
Step-by-step explanation:
If 12% leaks everyday, on the first day 12% would leak, leaving 100 - 125 = 88% of air
on the second day, 12% of 88% would leak = 0.88 x 0.12 = 0.1056
Air left on the second day = 88% - 10.56% = 77.44%
After a week = (100 - 12%)^7 = 49.87%
Answer:
1 / 10 (1 : 10) (10%) - your teacher has probably given you some idea as to the formatting of how you should write probability [so 3 different ways are written here], but I suspect they expect you to write it as 1 / 10
Step-by-step explanation:
only 1 out of all of these 10 trials is a "success" (aka what we are looking for)
we know that 7 matches the criteria of all years seeing a groundhog, and that all other options (1 , 2 , 3 , 4 , 5 , 6 , 8 , 9 , 10) do not meet this criteria.
so, the experimental probability** is 1 / 10 (or 1 : 10) (1 / 10 = 10%)
**: experimental probability is about how many times something happens in the experiment--not theoretically. it means that if his life was destined to be 1 of the 10, the probability of his experience matching the criteria is 1 / 10
experimental probability can be thought of as
successes / possible outcomes

The rational number, 5/7 converted to a decimal is 0.714.
<h3>What is the decimal?</h3>
A rational number is a number that can be expressed as a fraction of two integers.
A decimal is a non-integer in which the integers are separated from the non integers by a point. In order to convert the fraction to a decimal, divide the numerator by the denominator.
5/7 = 0.714
