An online spinner has two colored regions--blue and yellow. according to the website, the probability that the spinner lands in

the blue region on any spin is 0.80. Assume for now that this claim is correct. Suppose we spin the spinner 12 times and let x = the number of times it lands in the blue region.
Explain why X is a binomial random variable.​

Can you help me with this? 7
andrezito [222]

Answer:

65º

Step-by-step explanation:

  • The angle of a straight line is 180º, so ∠ABD=180º and ∠ABC=(180-6x)º
  • The sum of the interior angles of a triangle is 180, so (x+40)º+(3x+10)º+(180-6x)º=180
  • We can solve from there, x+40+3x+10+180-6x=180
  • Combine like terms, -2x+230=180
  • Subtract 230, -2x=-50
  • Divide by -2, x=25
  1. m∠CAB=(x+40)º=(25+40)º=65º
  2. m∠ABC=(180-6x)º=(180-150)º=30º
  3. m∠BCA=(3x+10)º=(75+10)º=85º

Find an equation of the line described below. Write the equation is slope-intercept from ( solved for y), when possible. Through
Sladkaya [172]

Answer:

The equation of the line that is passing through the point (5,4) and is parallel to x-axis would be y=4

Step-by-step explanation:

Given that the line passes through the point (5,4).

As the line is parallel to the x-axis, the slope of the line would be zero.

And we have point (5,4) from which the line is passing.

So, x_1=5\  ,\ y_1=4\ and\ m=0

The equation of the line passing through point (x_1,y_1) is

y-y_1=m(x-x_1)\\y-4=0(x-5)\\y-4=0\\y=4

So, the equation of the line that is passing through the point (5,4) and is parallel to x-axis would be y=4
