What is the value of x?

Mathematics

Answer:

x = 15√2

Step-by-step explanation:

Since the two angles on the triangle are the same, we can conclude that x is equal to the side that is adjacent to it too ( not the hypotenuse).

We will have x = a to use this pythagorean theorem as follows.

We will get the equation,

a = b

where

a^2 + b^2 = c^2

so,

a^2 + a^2 = c^2

2a^2 = 30^2

2a^2 / 2 = 900 / 2

√a^2 = √450

a = √450

a = 15√2

Your welcome, comment below if you have any questions! If you could mark this as brainliest I would appreciate it :D

The probability that a randomly selected elementary or secondary school teacher from a city is a female is , holds a second job
julsineya [31]

Answer:

The probability that an elementary or secondary school teacher selected at random from this city is a female or holds a second job is 0.90.

Step-by-step explanation:

Denote the events as follows:

<em>X</em> = an elementary or secondary school teacher from a city is a female

<em>Y</em> = an elementary or secondary school teacher holds a second job

The information provided is:

P (X) = 0.66

P (Y) = 0.46

P (X ∩ Y) = 0.22

The addition rule of probability is:

P(A\cup B)=P(A)+P(B)-P(A\cap B)

Use this formula to compute the probability that an elementary or secondary school teacher selected at random from this city is a female or holds a second job as follows:

P(X\cup Y)=P(X)+P(Y)-P(X\cap Y)\\=0.46+0.66-0.22\\=0.90

Thus, the probability that an elementary or secondary school teacher selected at random from this city is a female or holds a second job is 0.90.
