∠A=6x−18 ∘ start color #11accd, angle, A, end color #11accd, equals, start color #11accd, 6, x, minus, 18, degrees, end color #1
denpristay [2]

Using the properties of alternate angles, the value of x = 8 and ∠ A = 30

<h3>What are Alternate Angles?</h3>

A transversal that crosses two parallel lines produces alternate exterior angles. They form two pairs (four total angles) of alternate outside angles since they are situated "outside" the two parallel lines but on different sides of the transversal.

For the given question,

∠A=6x−18

∠B=14x+38

As, both parallel lines are intersected by a transversal,

the value of angle ∠A and ∠180 - B is same as they are alternate angles,

⇒ 6x−18 = 180 - 14x - 38

⇒ 6x + 14x = 142 + 18

⇒ 20x = 160

⇒ x = 8

∠A = 6x−18

⇒ ∠ A = 30

PLEASE ANSWER QUICKLY AND HELP ME!! THANK YOU SO MUCH!!
coldgirl [10]
Hello there!

To start off this problem, let's replace f(x) with x in the equation. This gives us the following.

x= \dfrac{3}{4} x+12

Subtract 3/4*x from both sides.

x- \dfrac{3}{4} x=12

\dfrac{4}{4} x-\dfrac{3}{4}x=12

\dfrac{1}{4} x=12

Now, multiply both sides by 4 to eliminate the fraction on the left side.

x=12*4=48

Your answer is B. Hope this helps! :)

The Boston public school district has had difficulty maintaining on-time bus service for its students ("A Year Later, School Bus
erma4kov [3.2K]

Answer:

Step-by-step explanation:

We would set up the hypothesis test. This is a test of a single population mean since we are dealing with mean

For the null hypothesis,

µ = 12

For the alternative hypothesis,

µ < 12

Since the population standard deviation is given, z score would be determined from the normal distribution table. The formula is

z = (x - µ)/(σ/√n)

Where

x = sample mean

µ = population mean

σ = population standard deviation

n = number of samples

From the information given,

µ = 12 minutes

x = 8 minutes

σ = 12 minutes

n = 36

z = (8 - 12)/(12/√36) = - 4/2 = - 2

Test statistic = - 2
