In this question, we have to write the set of points from -6 to 3 but excluding -2 and 3 as a union of intervals .
For union, we use U.
For the points that we have to exclude , we put parenthesis on there side that is ().
Therefore the required interval form is

As we see that () are used with -2 and 3 . And that's the required interval form .
Answer:
81 / 1024
Step-by-step explanation:
Given that :
Wheel is divided into 4:
Hence, probability of winning either 10%, 20%, 30% or 50% = 1/4
Probability of winning 50% discount = 1/4
Probability of not winning 50% discount :
1 - 1/4 = (4 - 1) /4 = 3/4
Hence, probability that 50% is won by 5th customer :
(3/4) * (3/4) * (3/4) * (3/4) * (1/4)
= (3/4)^4 * (1/4)
= (81 /256) *(1/4)
= 81 / 1024
Answer:
width = 2.5 feet
Step-by-step explanation:
Suzanne has a rectangular garden which is 18 feet long and 11 feet wide.
Area of the garden = length times width = 18 times 11= 198 square foot
Let 'w' be the width of the border
Length of the garden with border = 18+2w
Width of the garden with border = 11+2w
Area of the garden with border = 
Area of the border = 
She has 168 square foot of paving stones,

Solve for w
apply quadratic formula
a= 4, b= 58 and c=-168



we get two values for w
