Hmm
that is a true statement, the product of any 2 mixed numbers between 4 and 5, will be between 16 and 25
we can show that it is true by testing the bounds
if the number is 4 and the other is 4, then it is 16
we aren't allowed to do 4 since it isn't mixed and it equals 4
that is the lower bbound
if the numbes 5 and 5 are used, then it is 25
we arene't allowed to use 5 since it isn't mixed and it equals 5
so the product of any 2 numbers between 4 and 5 will be between 16 and 25
so pick any random one
4 and 3/4 times 4 and 5/323
Answer:
£29.75.
Step-by-step explanation:
15% = 0.15 as a decimal fraction.
Sale price = 35 - 0.15*35

Answer:
a) 88% is a population characteristic.
Step-by-step explanation:
A population characteristic, also known as population parameter, describes a characteristic about the entire population of variables (usually numerically). Basically, it is a description (usually numerical) about a group of variables, obtained from the total population of such a variable.
WHILE
A statistic describes that same characteristic, only that it is obtained from a sample of variables taken from the population.
For the question above, a department notices that 88% of ALL their customers who use the store's credit plan pay their bills on time. It is evident that this is a population charasteristic, as it is obtained from examining the entire population of customers.
Hope this Helps!!!
Answer:
It's line model A
Step-by-step explanation:
Hello,
y= x^3-4x²-3x+18=(x-3)²*(x+2)
y'=3x²-8x-3
y''=6x-8
1) Stationary points
Maximun: x=-1/3 ==>y=18,5185....
Minimum: x=3 ===>y=0 (double root)
2) x=4/3: point of inflection. (y''=0 and change sign)
