7 0

Answer:

  angles 1, 3, 6, 8 = 142°

  angles 2, 4, 5, 7 = 38°

Step-by-step explanation:

Vertical angles and corresponding angles are congruent, as are alternate interior angles. Hence the angles 1, 3, 6, 8 are all congruent:

  ∠1 = ∠3 = ∠6 = ∠8 = 142°

Each of the remaining angles forms a linear pair with one or another of those, so is its supplement:

  ∠2 = ∠4 = ∠5 = ∠7 = 180° -142° = 38°

katrin2010 [14]

Answer: H_0:\mu=120

H_A:\mu\neq120

Step-by-step explanation:

Let \mu denotes the average braking distance for a population of small car.

Given : It is advertised that the average braking distance for a small car traveling at 65 miles per hour equals 120 feet.

i.e. \mu=120

Objective of test : Whether the statement made in the advertisement is false

i.e.  \mu\neq120

Since '=' signs is contained by Null hypothesis and alternative hypothesis is against it.

So the null and the alternative hypotheses for the test will be:

H_0:\mu=120

H_A:\mu\neq120

Y = 6x - 4<br> y = -x + 3
likoan [24]

Answer:

  (1, 2)

Step-by-step explanation:

Subtract the second equation from the first:

  (y) -(y) = (6x -4) -(-x +3)

  0 = 7x -7 . . . . .  simplify

  0 = x - 1 . . . . . . divide by 7

  1 = x . . . . . . . . . add 1

  y = -1 +3 = 2 . . . substitute into the second equation

The solution is (x, y) = (1, 2).
