Find the value of x in this figure

1 answer:

3 0

Answer: 35
Each triangle adds up to 180 degrees by adding the two angles that you already have the value of (37+108) and subtract it from 180 to get the final angle(x) you get 35

Therefore x=35 :)

A random number generator is used to create a list of 300 single-digit numbers. Of those 300 numbers, 146 are odd and 154 are ev

Archy [21]

Answer:

0.44

Step-by-step explanation:

The total numbers drawn = 300

Out those 146 are odd and 154 are even.

The number 8 was drawn = 22 times

So, the number of times an even number other than 8 = 154 -22 = 132

The experimental probability = The number of favorable outcomes ÷ The number of possible outcomes.

The experimental probability of an even number other than 8 being generated = $\frac{132}{300}$

Simplify the above fraction to decimal, we get

= 0.44

Therefore, the answer is 0.44

Solve the equation exactly in the complex number system.<br> x^3+4x^2+9x+36=0

daser333 [38]

Factor by grouping.
0 = (x^3 +4x^2) +(9x +36) = x^2(x+4) +9(x+4) = (x^2+9)(x+4)

The first factor is the difference of squares (in complex numbers), so the form for factoring that can be used:
a^2 - b^2 = (a -b)(a +b)
Here, a=x, b=3i.

Then the factorization in complex numbers is
0 = (x -3i)(x +3i)(x +4)
Solutions are the values of x that make these factors be zero.

x = -4, -3i, 3i

The associative property of multiplication states that the grouping of factors does not change the product. Example?

An example is (3x7)x5 = (5x7)x3.
