Answer:
Step-by-step explanation:
175-(8+45÷3)x7 s
start with what's inside the parenthesis
(8+45÷3) ⇒ (8+15) ⇒(23)
175-(23)x7
then do multiplication
23x7
161
175-161
14
final answer is 14
there are nine ducks and 3 swans
sqrt of 9 equals 3
3 + 9 = 12
Step-by-step explanation:
Any complex number is of the form:
where a is real part and B is imaginary part.
Therefore, in given complex number:
7 is real part.
is imaginary part.
Hence, first two options are correct.
Last two options are incorrect because of the following reasons:
is coefficient of
& not
Given number is a difference of a real number and imaginary number & not a sum of a real number and imaginary number.
Can u show us how the location looks please?
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:

Compute the probability that a randomly selected depth is between 2.25 m and 5.00 m as follows:

![=\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.
