Step-by-step explanation:

There are 3 possibilities

1- Train will arrive early

2- Train will arrive on time

3- Train will arrive late

Formula for Probability of event a is = n(a)/Sum of events

In this case sum of events = 3

Probability of early arrival = 1/3

Probability of on time arrival = 1/3

Probability of late arrival = 1/3

Which expression is equivalent to 7h^2-252k^2?

gulaghasi [49]

Answer:

Step-by-step explanation:

252 = 7 *36

36 = 6 *6 = 6²

a² -b² = (a + b)(a - b)

7h² - 252k² = 7(h² - 36k²)

= 7(h² - [6k]² )

= 7(h +6k)(h - 6k)

What is the slope of the line that passes through the points (-2, -1) and (2, -3)?

Lady bird [3.3K]

Answer:

$m=\frac{-1}{2}$

Step-by-step explanation:

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Simply plug in the 2 coordinates into the slope formula to find slope m:

$m=\frac{-3-(-1)}{2-(-2)}$

$m=\frac{-3+1}{2+2}$

$m=\frac{-2}{4}$

$m=\frac{-1}{2}$

Y 45° 30° N 17 I need help pls

melisa1 [442]

Answer:

x=29.4

Step-by-step explanation:

To help find the sides of a triangle, I use SOHCAHTOA.

SOH - CAH - TOA

S=O/H ( $Sine=\frac{opposite}{hypotenuse}$ )

C=A/H ( $Cosine=\frac{adjacent}{hypotenuse}$ )

T=O/A ( $Tangent =\frac{opposite}{adjacent}$ )

Let's find x first. We know 2 parts of the triangle: the adjacent leg, and the angle that is opposite of that.

So it would be tangent (tan).

opposite = 17

adjacent = 30°

Plug these numbers into the calculator and you should get your answer.

$\frac{17}{tan(30)} = 29.44486372...$

x=29.4

Try to do y on your own and let me know if you have any questions!

Also correct me if I'm wrong on anything.

Hope this information helps!
