a is less than zero
Step-by-step explanation:
i got it right
If you have two negatives they cancel each other out and make a positive. The same if you have to positives the product will be positive. If you have a negative and a positive you multiply the numbers and bring down the negative. Same if you have a positive and a negative. Only two negatives cancel each other out, same with positives. For example -4(-5)(-1) you would use order of operations, 4 and the 5 cancel each other out and you multiply 20 by -1 which is -20 since you bring down the negative.
The lateral surface area consists of 2 sides with 11 unit long and 4 unit high, and 2 sides with 8 unit long and 4 unit high. Each side is a rectangle. So basically you use area of rectangle to determine the lateral surface area
lat sa = 2 × area of rectangle + 2 × area of rectangle
In this case, it will be
lat sa = (2 × l × h) + (2 × w × h)
lat sa = (2 × 11 × 4) + (2 × 8 × 4)
lat sa = 88 + 64
lat sa = 152
The lateral surface area is 152 squares unit
Answer:
mean= 4.68
variance= 1.0296
Step-by-step explanation:
mean= n×p
n=6
p=0.78
mean= 6×(0.78)
= 4.68
variance= n×p×(1-p)
= 6 × 0.78×(1-0.78)
= 1.0296
She would have a total of 40 stamps.
