VIIIe in the standard (x,y) coordmate pralit nas

Savatey [412]

The coordinates of point B are (-4 , -2) ⇒ answer H

Step-by-step explanation:

In any circle

The diameter of the circle passing through its center
The center of the circle is the mid-point of all diameters

If (x , y) are the coordinates of the mid-point of a line whose end

points are $(x_{1},y_{1})$ and $(x_{2},y_{2})$ , then

$x=\frac{x_{1}+x_{2}}{2}$ and $y=\frac{y_{1}+y_{2}}{2}$

∵ Point C is the center of a circle

∵ AB is the diameter of the circle

∴ C is the mid point of AB

∵ A = (2 , 6) ⇒ $(x_{1},y_{1})$

∵ B = $(x_{2},y_{2})$

∵ C = (-1 , 2) ⇒ (x , y)

- Use the rule of the mid-point above

∵ $-1=\frac{2+x_{2}}{2}$

- Multiply both sides by 2

∴ -2 = 2 + $x_{2}$

- Subtract 2 from both sides

∴ $x_{2}$ = -4

∴ The x-coordinate of point B is -4

∵ $2=\frac{6+y_{2}}{2}$

- Multiply both sides by 2

∴ 4 = 6 + $y_{2}$

- Subtract 6 from both sides

∴ $y_{2}$ = -2

∴ The y-coordinate of point B is -2

The coordinates of point B are (-4 , -2)

The manager of a grocery store reports that there is a 12 percent chance that a customer buys apples during a shopping trip, a 5

Ivanshal [37]

Answer:

The probability of a customer buying carrots is 0.10.

Step-by-step explanation:

Here, given:

P (Customer buying apples) = 12%

⇒ P(A) = 12 \100 = 0.12

P(Customer Buying apples AND Carrots) = 5%

⇒ P(A ∩ C ) = 5 /100 = 0.05

P(Customer buying apples OR carrots ) = 17%

⇒ P(A∪ C) = 17/100 = 0.17

Now, we know that:

<h3> P(X ∪ Y) = P(X) + P(Y) - P(X ∩ Y ) </h3><h3></h3>

Now, here substituting the values, we get:

P(A∪ C) = P(A) + P(C) - P(A ∩ C )

⇒ 0. 17 = 0.12 + P(C) - 0.05

or, 0.17 - 0.07 = P(C)

or, P(C) = 0.10

or, P(Customer Buying Carrots) = 0.10

Hence, the probability of a customer buying carrots is 0.10.
