When randomly selecting an adult, A denotes the event of selecting someone with blue eyes. What do Upper P (Upper A )P(A) and U

bezimeni [28]

Answer:

P(A): It is the probability of selecting someone with blue eyes.

$P(\bar{A})$ : It is the probability of selecting someone who does not have blue eyes

Step-by-step explanation:

We are given the following in the question:

A: event of selecting someone with blue eyes.

Probability:

The probability of an event tells the chances of happening of that event.

It is mathematically defined as:

$\text{Probability} = \displaystyle\frac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}$

Complement of an event:

It is the event that consist of all outcomes not happening in A.

It is represented by $\bar{A}$

$P(A) + P(\bar{A}) = 1$

We have to explain the representation:

a) P(A): It is the probability of selecting someone with blue eyes.

It gives us the chances of someone having blue eyes.

b) $P(\bar{A})$ : It is the probability of selecting someone who does not have blue eyes

It is the chances of selecting someone who does not have blue eyes.

Which statement accurately describes the movement of an object under a translation vector (-3)? The object moves 2 units down an

statuscvo [17]

The object moves 2 units to the left and then 3 units up.

<h3>Translation of vectors</h3>

Translation is a transformation technique used to change the position of an object on the xy-plane.

Given the translation vector (-2, 3), this translation shows a movement of an object to the left by 2units and 3 units in the upward direction

MARKNING BRAINLEST ! :) * The table shows a linear function, find the values of A , B , & C. Show your work.

lawyer [7]

Answer:

A = 11, B = 25/3, C = -1

Step-by-step explanation:

A linear function has the form:

f(x) = ax + b

(1)

f(3) = 8a + b = 8

f(5) = 5a + b = 9

Using the last 2 equations we can solve for 'a' and 'b'.

8a + b = 8 | 5a + b = 9

We multiply the second one by -1:

8a + b = 8 | -5a -b = -9

And then we add them together:

3a = -1

a = $\frac{-1}{3}$

We then solve for 'b':

5a + b = 9

5(-1/3) + b = 9

b = 9 + 5/3

b = 32/3 = $11\frac{1}{3}$ .

We then use this to find A, B, C.

f(x) = (-1/3)x + 32/3

(2)

f(A) = -A/3 + 32/3 = 7

$\frac{-A}{3} + \frac{32}{3} = 7\\A - 32 = -21\\A = 11$

(3)

f(7) = -7/3 + 32/3 = B

25/3 = B

(4)

f(C) = -C/3 + 32/3 = 11

$\frac{-C}{3} + \frac{32}{3} = 11\\C - 32 = -33\\C = -1$
