A square in the board below and a letter in the word ATTENTION is chosen at
kolezko [41]

Answer:

4 /15

Step-by-step explanation:

From the number cube :

Count of Numbers greater than 4 = 16

Sample space of number cube = 20

P(number greater than 4) = 16 / 20 = 4/5

Word : ATTENTION

Count of letters in attention = 9

Count of T's in attention = 3

P(choosing T) = 3 / 9 = 1/3

P(greater than 4, then T) = 4/5 * 1/3 = 4 /15

lbvjy [14]

$5.50. if he washes his dog every week, he is getting $6.60 automatically. So if we do simple math, 12.10-6.60= 5.50

Suppose angles a and B are the two acute angles in a right triangle and that b < a. Apply the relationship between sine and c
Valentin [98]

The right statements are: A, B and E

Sin(A)=cos(B)

then we check if using x=9 this holds true:

sin(6x-10)=cos(4x+10)

sin((6*9)-10) = sin(44º)

cos(4x+10)=cos(46)

Sin(44)=0.694=cos(46)

then a is true

Now, we know that b

What is the least possible value of (x+1)(x+2)(x+3)(x+4)+2019 where x is a real number?
Mrrafil [7]

The least possible value of (x+1)(x+2)(x+3)(x+4)+2019 where x is a real number is 2018

<h3>What is an Expression ?</h3>

An expression is a mathematical statement consisting of variables , constant and mathematical operators.

The expression given is

(x+1)(x+2)(x+3)(x+4)+2019

To find the minimum value

(x+1)(x+2) = ( x² +3x +2) = ( x +5/2)² - 9/4

(x+3)(x+4) =  (x² +7x +12) = ( x +5/2)² -1/4

(x+1)(x+2)(x+3)(x+4) = (  x +5/2)⁴ - 5/2 ( x +5/2)² +9/16

Considering ( x +5/2)²  = y

(x+1)(x+2)(x+3)(x+4) = y² - 5/2y + 9/16

(x+1)(x+2)(x+3)(x+4) = ( y - 5/4)² - 1

(x+1)(x+2)(x+3)(x+4) = (  ( x +5/2)² -5/4)² - 1

The minimum value when x is a real number is -1

( x +5/2)² -5/4) = 0

-1 +2019 = 2018

x has two possible real solution

and the least possible value of (x+1)(x+2)(x+3)(x+4)+2019 where x is a real number is 2018.
