the measure of an angle is 12 less than twice the measure of its supplement. what is the measure of the angle
Alex

Answer:

Two angles are said to be supplementary if they add up to 180 degrees. So the supplement of an angle is obtained by subtracting it from 180. i.e., if x is an angle, its supplement is 180−x

Six times a number increased by 20 is four less than eight times the number. Find the number
DaniilM [7]
Greetings!

"<span>Six times a number increased by 20 is four less than eight times the number. Find the number."...

This would be, as an equation:
</span>6x+20=8x-4

Solve:
Add 4 and -6x to both sides.
(6x+20)+4+(-6x)=(8x-4)+4+(-6x)
Simplify.
24=2x
Divide both sides by 2.
(24)/2=(2x)/2
Simplify.
12=x
x=12
<span>
x=12

Hope this helps.

Which of the following is equal to the fraction below?
Vesna [10]

In mathematics there is a rule of exponents where we can "distribute" the powers/exponents in the numerator and denominator of any expression. Therefore, given an expression as (\frac{a}{b})^n, the exponent n can be "distributed" as: (\frac{a}{b})^n= \frac{a^n}{b^n}.

In our case, the power, n=11; a=7 and b=4. Thus, the expression (\frac{7}{4})^{11}, can be written as \frac{7^{11}}{4^{11}}.

Thus, out of the given options, option A is the correct option.

Determine if events A and B are independent.
trapecia [35]

Answer:

B) Independent

Step-by-step explanation:

Independent events:

Two events, A and B are independent, if:

P(A \cap B) = P(A) \times P(B)

In this question:

P(A \cap B) = \frac{63}{200}

P(A) \times P(B) = \frac{9}{20}*\frac{7}{10} = \frac{9*7}{20*10} = \frac{63}{200}

Since P(A \cap B) = P(A) \times P(B), these events are independent.
