Answer:

Y=9

Step-by-step explanation:

Because it passes through two points in a straight line, it must have no coefficient for x, just a Y-Intercept equal to the Y of the two points.

Me need help pweaseee can anyone help

Kryger [21]

Answer:

Step-by-step explanation:

A 90 degree rotation would be a rotation of 90° about the origin. Knowing this, we can eliminate C since it is a 180° rotation. We can also eliminate A, as it would be a 0° or 360° rotation. This leaves us with B and C.

A counterclockwise rotation would be one that goes the opposite direction of the rotation of the hands of a clock. A 90° counterclockwise rotation would yield triangle B, making that our answer.

I hope you find my answer and explanation to be helpful. Happy studying.

The circle passes through the point (−2, 3) with a center of (-4,6). What is its radius?

Ganezh [65]

Answer:

radius = √13

Step-by-step explanation:

Forming the equation :

(x - h)² + (y - k)² = r²

(x, y) = point on circle
(h, k) = center of circle
r = radius

Solving :

(-2 + 4)² + (3 - 6)² = r²
r² = 4 + 9
radius = √13

MATH HELP!!!!!!!!!!!!!!!!!!!!!!!!!!

Marina CMI [18]

Question 2. :

8^2 = 64 and 9^2 = 81, therefore the square root of 65 falls between these two values, 8 and 9, 64<65<81

Question 3. :

13^2 = 169 and 14^2 = 196, the correct answer is square root of 175, because 169<175<196

Hope this helps, you only need to know the squared values and square roots.

Guilt in decision making. The effect of guilt emotion on how a decision maker focuses on the problem was investigated in the Jan

bearhunter [10]

Answer:

a) 33.33% probability that the respondent is assigned to the guilty state.

b) 35.09% probability that the respondent chooses the stated option (repair the car).

c) 26.32% probability that the respondent is assigned to the guilty state and chooses the stated option.

d) 40.94% probability that the respondent is assigned to the guilty state or chooses the stated option.

Step-by-step explanation:

A probability is given by the number of desired outcomes divided by the number of total outcomes. We use this concept, along with the given table, to solve the question.

a. Find the probability that the respondent is assigned to the guilty state.

There were 171 participants, and 57 of those were assigned the guilty state. So this probability is $p = \frac{57}{171} = 0.3333$

b. Find the probability that the respondent chooses the stated option (repair the car).

There were 171 participants, and 60 of those choose the stated option. So this probability is $p = \frac{60}{171} = 0.3509$

c. Find the probability that the respondent is assigned to the guilty state and chooses the stated option.

There were 171 participants, and 45 of those were assigned to the guilty state and choose the stated option. So this probability is $p = \frac{45}{171} = 0.2632$

d. Find the probability that the respondent is assigned to the guilty state or chooses the stated option.

Guilty state: 57

Anger or Neutral and stated option: 8 + 7 = 15

Total = 57 + 15 = 72

$p = \frac{70}{171} = 0.4094$
