Answer: 0.9

Step-by-step explanation:

For any event A , the probability of event A will occur be P(A).

Then , the probability of not occuring the event A will be given by :-

\text{P(A')=1-P(A)}

The given statement : The probability that an event will occur is 0.1.

That is , P(A)=0.1

Now, the probability that the event will NOT occur is given by :-

\text{P(A')}=1-0.1\\\\\Rightarrow\ \text{P(A')}=0.9

Hence, the probability that the event will NOT occur = 0.9

Using the quadratic formula to solve 4x^2-3x+9=2x+1, what are the values of x?
labwork [276]

Rewrite 4x^2-3x+9=2x+1 as 4x^2-5x+8 = 0


Here, a = 4, b = -5 and c = 8. Then,


5 plus or minus sqrt (25 -4(4)(8) )

x = ------------------------------------------------------

8

5 plus or minus sqrt (-103)

= --------------------------------------

8

5 plus or minus i*sqrt(103)

Then x = ----------------------------------------

8


= ---------------------------------------------

8

= ----------------------------

Find the volume of a pyramid with a square base, where the side length of the base is
ValentinkaMS [17]

Answer:

<h2>1529.4 m³</h2>

Step-by-step explanation:

Volume of a pyramid can be found by using the formula

v =  \frac{1}{3}  \times a \times h \\

a is the area of the base

h is the height

Since the base is a square we have

v =  \frac{1}{3}  \times  {15.3}^{2}  \times 19.6 \\  = 78.03 \times 19.6 \\  = 1529.388

We have the final answer as

<h3>1529.4 m³</h3>

Hope this helps you

Find the equation of a line that is parallel to the line -3x+2y=10 and goes through the point (0,7).
Delvig [45]

Answer:

  3x -2y = -14

Step-by-step explanation:

The parallel line will have a new constant that can be found by substituting the given point for x and y.

  -3x +2y = -3(0) +2(7) = 14

An equation for the parallel line is ...

  -3x +2y = 14

__

In standard form, the leading coefficient is positive, so the standard form equation is ...

  3x -2y = -14

The equation of a line?
Mandarinka [93]
Y - 5 = m[ x - ( - 2 ) ] is <span>the "point-slope" form of your staright - line equations;
y - 5 = m( x + 2 ) ;
But,  your line is parallel to y = ( 2 / 3 )x + 1;
 m = 2 / 3;
Finally, y - 5 = ( 2 / 3)( x +  2);
 y = 5 + ( 2 / 3)x + 4 / 3;
y = ( 2 / 3 )x + 15 / 3 + 4 / 3 ;
y = ( 2 / 3 )x + 19 / 3.
