Answer:

D) 180 miles / 6 gallons

Step-by-step explanation:

180 / 6 simplified is 30 / 1. Although C has the same numbers, the numbers are switched. 6 / 180 simplified would be 1 / 30. This is not the same as 30 / 1.

Find the values of x and y in the d
tia_tia [17]

9514 1404 393

Answer:

  • x = 20
  • y = 10

Step-by-step explanation:

The angle marks show that ΔRST is isosceles, so RT = RS. They also show ΔRTU to be equilateral, so UT = RT.

  UT = RS

  x -5 = 15

  x = 20 . . . . . . add 5

__

ΔRTU is equilateral, so ∠RTU is 60°. The angle marked 3y° is complementary to that.

  3y = 30

  y = 10 . . . . . divide by 3

QUESTION 3 I [12] A student must answer a multiple-choice question with five possible answers. He knows the correct answer with
wel

The probability that the student does not know the answer but he randomly guesses it is 0.146025

<h3>How to solve for the probability of having a correct guess</h3>

The question has only one right answer out of 5 choices.

Probability he answers incorrectly:

1 - 0.55 * 4/5

= 0.45 * 0.8

= 0.36

Probability he does not know answer but answers the question correctly

\frac{(1-0.55)\frac{1}{5} }{0.55+(1-0.55)\frac{1}{5} }

= 0.09/0.55+0.09

= 0.140625
