The chace of the number that will be pulled out of the hat being an even number is a 7 / 15 chance.

Answer:

the theoretical probability that a slip of paper that is chosen will be an even number is 0.466

Step-by-step explanation:

if we are going to choose a slip of paper with an specific condition, the theoretical probability could be calculated as a division between the total number of posibles choices and the number of choices that satisfy an specific condition.

In this case, there 15 posibles choices because we have 15 numbered slips of papers. from these 15 slips, 7 are numbered with an even number. This even numbers are: 2, 4, 6, 8, 10, 12 and 14.

Finally the theoretical probability is:

\frac{7}{15} =0.466

The original price of a jar of paint is$1.20 the store manager gets a 10 percent discount on orders of at least 50 jars of paint
sleet_krkn [62]

Answer:

$54

Step-by-step explanation:

50 * $1.20 = $60

Before the discount, 50 jars cost $60.

Since the discount rate is 10%, he will pay only 90% of the price since 100% - 10% = 90%.

90% of $60 =

= 90% * $60

= 0.9 * $60

= $54

Write the standard equation for the hyperbola with the following conditions: vertices: (-2, -3) and (6, -3) foci: (-4, -3) and (
STALIN [3.7K]
Hello,

Vertices are on a line parallele at ox (y=-3)

The hyperbola is horizontal.

Equation is (x-h)²/a²- (y-k)²/b²=1

Center =middle of the vertices=((-2+6)/2,-3)=(2,-3)
(h+a,k) = (6,-3)
(h-a,k)=(-2,-3)
==>k=-3 and  2h=4 ==>h=2
==>a=6-h=6-2=4 (semi-transverse axis)

Foci: (h+c,k) ,(h-c,k)
h=2 ==>c=8-2=6

c²=a²+b²==>b²=36-4²=20

Equation is:
\boxed{ \dfrac{(x-2)^2}{16} - \dfrac{(y+3)^2}{20} =1}

What are the x and y intercepts of 3y=2x-6
sasho [114]
How to find the x intercept of 3y=2x-6: (when y is 0)

3(0) = 2x - 6

     0 = 2x - 6
   +6        + 6
-------------------------
     6 = 2x
  ------ -----
     2     2
      
     x = 3


How to find the y intercept of 3y=2x-6: (when x  is 0)

 3y = 2(0) - 6

 y = 0 - 6

  3y = -6
------  -----
   3      3

   y = -2
