a(2)+4(2)=8(2)

4×4=16 8×8=64

16-16 64-16

a(2)=6.9

Caculator:

Press 2nd, press x2(close to bottom left)

6.92 PLEASE ROUND

6.92=6.9

P(a)=0.50 p(b)=0.30 and p(a and b)=0.15 what is p(a or b)

Softa [21]

Answer:

Option C is correct

P(A or B) = 0.65

Step-by-step explanation:

Given:

P(A) =0.5

P(B)=0.30

P(A and B) =0.15

( The probability of the happening of both independent events will be there product) P( A and B ) =P(A).P(B)

Solution:

To find the probability of the Happening of event A either event B we will use the following formula

P(A or B) = P(A) + P(B)-P(A and B)

= 0.5 + 0.3 - 0.15

=0.65

How many solutions does the system of equations below have? y= 3x + 4 2y -8 = 6x

Cerrena [4.2K]

Answer:

infinitely many solutions (infinite solutions)

Step-by-step explanation:

2y - 8 = 6x

+8 +8

-------------------------------

2y = 6x + 8

$\frac{2y}{2}$ = $\frac{6x}{2}$ + $\frac{8}{2}$

-------------------------------

y = 3x + 4

Because 3x + 4 = 3x + 4, there are infinitely many solutions to this system of equations. This is because they're the exact same equations. Any substitution for x will give you a true statement to y when compared to the other equation.
