Answer:

The solution of given equation is x = -4

Step-by-step explanation:

We are given the following in the question:

Let x be the variable such that

x \in (-12,12)

Relation:

The quotient of a number and 4 is negative 1

We can write the equation as:

\dfrac{x}{4} = -1

Solution:

\dfrac{x}{4} = -1\\\\\Rightarrow x = 4\times -1\\\Rightarrow x = -4

Thus, the solution of given equation is x = -4

Answer:

The responsess to the given question can be defined as follows:

Step-by-step explanation:

P(medication\ used) = 0.007 \\\\P( drug \not\ used ) = 1 - 0.007 = 0.993\\\\P(test\ positive  | medication \ used) = 0.96 \\\\ P(test \ negative | medication \ used) = 1 - 0.96 = 0.04\\\\

P(Point | Non-used\ medication )=0.93\\\\ P(Point |No\ medication ) = 1 - 0.93 = 0.07

As per the given info we draw the tree diagram which is defined in the attachment file.

P ( test \ is\  positive ) = P( medication \ used ) \times P( Test \ positive | medication \ used ) + P( medication not \ used ) \times  P( Test\ positive | medication \ not \ used )

                  = ( 0.007 \times 0.96 ) + ( 0.993\times 0.07 )\\\\= 0.0762

P( medication \ used | test\ positive )= \frac{\textup{P( medication used ) *P( Test positive given medication  used )}}{\textup{P( medication used )}}  

= \frac{( 0.007\times 0.96 )}{0.0762}\\\\= 0.0882

%to find the euclidean distance between two vectors, find the 2-norm of the difference of %those vectors. enter column vectors u
sergij07 [2.7K]

the norm of the distance is |d|=97.95 ft

the vector of the distance is d=96i+18j+27k

  • Vector : a quantity having direction as well as magnitude, especially as determining the position of one point in space relative to another.
  • an organism, typically a biting insect or tick, that transmits a disease or parasite from one animal or plant to another.
  • Step-by-step explanation:
  • As per the attached image, the distance from the origin of the x y & z axis is where the vector starts and it ends at the opposite side of the room.
  • Calculating the norm as the square root of the sum of each side of the rooms squared & calculating the vector as each side of the room multiplied by the i, j & k axis, the results are as mentioned above.

How to answer this on descending powers of x please help pretty please
zheka24 [161]

Answer:  25x² - 64

<u>Step-by-step explanation:</u>

  (5x + 8)(5x - 8)

=        5x(5x - 8)   +    8(5x - 8)

=      25x² - 40x    +    40x - 64

=      25x²         + 0x           - 64

=              \large\boxed{25x^2-64}

NOTE: descending powers means the biggest exponent goes first, then the next biggest exponent, etc.

For example: x⁴ then x³ then x² then x then the number (which is actually x⁰)
