Answer: False
Nothing is 100% certain no matter how sure it seems. This is especially true with statistics. There's always going to be some amount of error. The goal is to minimize the error as much as possible in the best cost-effective manner.
Answer:
Step-by-step explanation:
200 divided by 25 is 8
so do 48 divided by 8
you get $6 for 25 beads
200 divided by 6 is 33.33
so do 48 divided by 33.33
you get about $1.50
A polygon has 5 sides you can find the length of one side by dividing the total perimeter of 18 by the number of sides of 5. giving you 3.6
Answer:
This is truly false.
When determining which x-values would make an expression undefined, you do need to include the factors you canceled out.
Step-by-step explanation:
When working with functions, it is said to be undefined when the value of the function doesn't take on a value, and this occurs when the denominator is equal to 0.
Take for example
(x-2)/(x-2)
This simple function can be simplifted further by cancelling out the factors to get 1, but that doesn't change the fact that, at x=1, this function becomes undefined.
Because, the values of x can vary and can take on values that can make the denominator to be 0, factors that are cancelled need to be included in checking for where a function is undefined.
Hope this Helps!!!!
Answer:
The area has decreased a 10%.
Step-by-step explanation:
Lets suppose that the the sides of the square are 1 cm, so the area is 1 .
so if the square has been reduced 40% in widht, the new widht is 60% of what it was before. that means 0.6cm
then it was increased 50% on height, so the new height is 1.5 cm
The area of a rectangule is (height*widht)
A=(0.6*1.5)
A=0.9 []
The area of 0.9 represent the 90% of the first area, so the area was reduced a 10%. (100%-90%).
