<h3>Answer:  21</h3>

==================================

Work Shown:

Vertical angles are always congruent.

This means they are equal in measure.

A = B

3x-30 = 2x-9

3x-2x = -9+30

x = 21

--------

Side note:

if x = 21, then,

A = 3*x-30 = 3*21-30 = 33 degrees

B = 2*x-9 = 2*21-9 = 33 degrees

Find the probability that a Type A bulb lasts at least 300 hours and a Type B bulb lasts at least 400 hours.
barxatty [35]

Answer:

P(X>3)P(X>4)=(1-F_1(3))(1-F_2(4))

Step-by-step explanation:

We require more information by I will explain in principle:

If Type A has at least 300 hours and Type B at least 400 hours.

(X>3)(Y>4)=P(X>3)P(X>4)

You need to determine the Probability density function of X and Y and then subtract 1 from both

P(X>3)P(X>4)=(1-F_1(3))(1-F_2(4))

This will give you the probability of the expression.

GUYS HELP NOW PLS WHAT IS THE PROBABILITY NOTATION FOR THE PROBABILITY OF CHOOSING A GREEN MARBLE HELPPPP PLS
guapka [62]

The probability notation for the probability of choosing a green marble is P(G)

<h3>What is probability?</h3>

This is simply defined as the extent to which something is likely to occur.

The probability that an event will occur is given as the ratio of the number of favorable outcomes to the total number of outcomes.

<h3>How to determine the probability notation</h3>

Probability notation is a symbol used in indicating the probability of an occurring event. Since our focus is on the probability of obtaining a green marble, then the probability notation will be P(G). This is illustrated below:

  • Event of green marble = nG
  • Total event = nT
  • Probability of green marble = P(G)

P(G) = nG / nT

A jacket is on sale for 20% off the regular price. The sale price ism$50.00. What is the regular price of the jacket?
Delicious77 [7]
Lets solve for x.

 0.8x = 50. - Remember that the jacket was 80% of the original price.

Thus, divide by x.

x = 50 / 0.8
x = 62.5
