Answer:

slope is -4

Step-by-step explanation:

Find slope which is also referred to as m:

m = (y₂ - y₁) / (X₂ - X₁)

   = (-7 - 5) / (1 - (-2)

   = -12 / 3

m = -4

Not asked in question but if you want to find equation for the line:

Find b using any one of the two provided coordinates. Let's use (-2, 5).

y = mx + b

5 = -4(-2) + b

5 = 8 + b

b = -3

Use m and b to make equation.

y = mx + b

y = -4x - 3

Answer:

  • -4

Step-by-step explanation:

<u>Given points </u>

  • (-2, 5) (1, -7)

<u>Use slope formula to find the slope</u>

  • m = (y2 - y1)/(x2 - x1)
  • m = (-7 -5)/(1 + 2) = -12/3 = -4

Slope is -4

In a city school, 60% of students have blue eyes, 55% have dark hair, and 35% have blue eyes and dark hair. What is the probabil
gulaghasi [49]

Answer:

58%

Step-by-step explanation:

This is a problem of conditional probability.

Let A represent the event that student has dark hair.

So P(A) = 55% = 0.55

Let B represents the event that student has blue eyes.

So, P(B) = 60% = 0.60

Probability that student has blue eyes and dark hairs = P(A and B) = 35% = 0.35

We are to find the probability that a randomly selected student will have dark hair, given that the student has blue eyes. Using the given formula and values, we get:

P(A|B)=\frac{P(A \cap B)}{P(B)}\\\\ P(A|B)=\frac{0.35}{0.60}\\\\ P(A|B)=0.58

Therefore, there is 0.58 or 58% probability that the student will have dark hairs, given that the student has blue eyes.

Please help me find x<br> Need help fast!!
Bond [772]

Answer:

x = 100°

Step-by-step explanation:

p and q are parallel lines. Construct line 'l' parallel to p and q

a = 30°   {p// l  when parallel lines are intersected by transversal alternate interior angles are congruent}

c +110 = 180  {linear pair}

c = 180  - 110

c = 70°

b= c   {q // l  when parallel lines are intersected by transversal alternate interior angles are congruent}

b = 70°

x = a + b

x = 30° + 70°

x = 100°
