Answer:
Step-by-step explanation:
a.18/-3 = (-6)
b. -5/-1 = 5
c. 24/-6 = (-4)
d. -10/-1 = 10
e. -25/5 =(-5)
f. 8/-2 = (-4)
In multiplication and division, if there are are odd number of negative signs, the result will have negative sign.
If there are even number of negative signs, the the result will have positive sign
Uh I don’t think so.
Sorry! But stay safe! :)
Answer:
The probability that a randomly selected depth is between 2.25 m and 5.00 m is 0.55.
Step-by-step explanation:
Let the random variable <em>X</em> denote the water depths.
As the variable water depths is continuous variable, the random variable <em>X</em> follows a continuous Uniform distribution with parameters <em>a</em> = 2.00 m and <em>b</em> = 7.00 m.
The probability density function of <em>X</em> is:
![f_{X}(x)=\frac{1}{b-a};\ a](https://tex.z-dn.net/?f=f_%7BX%7D%28x%29%3D%5Cfrac%7B1%7D%7Bb-a%7D%3B%5C%20a%3CX%3Cb)
Compute the probability that a randomly selected depth is between 2.25 m and 5.00 m as follows:
![P(2.25](https://tex.z-dn.net/?f=P%282.25%3CX%3C5.00%29%3D%5Cint%5Climits%5E%7B5.00%7D_%7B2.25%7D%20%7B%5Cfrac%7B1%7D%7B7.00-2.00%7D%20%5C%2C%20dx)
![=\frac{1}{5.00}\int\limits^{5.00}_{2.25} {1} \, dx\\\\=0.20\times [x]^{5.00}_{2.25} \\\\=0.20\times (5.00-2.25)\\\\=0.55](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1%7D%7B5.00%7D%5Cint%5Climits%5E%7B5.00%7D_%7B2.25%7D%20%7B1%7D%20%5C%2C%20dx%5C%5C%5C%5C%3D0.20%5Ctimes%20%5Bx%5D%5E%7B5.00%7D_%7B2.25%7D%20%5C%5C%5C%5C%3D0.20%5Ctimes%20%285.00-2.25%29%5C%5C%5C%5C%3D0.55)
Thus, the probability that a randomly selected depth is between 2.25 m and 5.00 m is 0.55.

Answer:
x = -6
Step-by-step explanation:
That's it. That's the vertical line through (-6, 6).
Literally just the x-coordinate (because it will be parallel to the y-axis, draw it out on a paper if confusion).
