Answer:

  • x +3x = 180
  • x = 45 . . . . . . . choice C
  • 3x = 135 . . . . . choice F

Step-by-step explanation:

Let x represent the measure of the original angle in degrees. Three times its measure is 3x. That will be the supplement if the sum of the two angles is 180°.

  x + 3x = 180 . . . . . . . . . equation for finding the angle

  x = 180/4 = 45 . . . . . .  divide both sides by 4

  3x = 3(45) = 135

The first angle is 45°. The second angle is 135°.

The test to detect the presence of a certain protein is 98% accurate for corn plants that have the protein and 97% accurate for
larisa [96]

Using the given percentages, it is found that the probability that a randomly chosen plant is detected incorrectly is 0.02965 = 2.965%.

<h3>Percentages:</h3>

The percentages associated with an incorrect detection are:

  • 2% of 3.5%(have the protein).
  • 3% of 96.5%(do not have the protein).

Hence:

p = 0.02(0.035) + 0.03(0.965) = 0.02965

The probability that a randomly chosen plant is detected incorrectly is 0.02965 = 2.965%.
