Answer:
D
Step-by-step explanation:
A is an arithmetic sequence in that is adds or subtracts the same amount.
B is also an arithmetic is that it takes the original 1000 and adds another 1000 for each year
C is a geometric sequence because it's losing 5× however many questions missed
D is the answer because it says it loses 10% every year, so it loses 10% of the previous year, not the beginning year.
Answer:
6
Step-by-step explanation:
A quadratic function is a function of the form f(x) = ax^2 +bx+c, where a, b, and c are constants and a <> 0. (a not equal to 0)
The term ax^2
is called the quadratic term (hence the name given to the function), the term bx is called the linear term, and the term c is called the constant term.
Answer:
Standard deviation = 0.547
Step-by-step explanation:
Given the data
$5 for spade
$10 for any club
$20 for an ace club
Lets assume Probability of getting these cards to be
0.5, 0.20 and 0.30
Therefore, mean would be
Summation (PX) = 5×0.5 + 10×0.2 +20×0.3
Summation (PX)/n= 10.5/35 = 0.3
Standard deviation = √0.3
Standard deviation = 0.547
Answer:
The area of the composite area is 400 square millimeters.
Step-by-step explanation:
The area of the composite figure (
), in square millimeters, is found by multiplying the area of the equivalent rectangle, in which a semicircle of the original rectangle is move to the opposite side of the figure, so that quantity of area is conserved:
(1)
Where:
- Width, in millimeters.
- Height, in millimeters.
If we know that 
, the area of the composite figure is:
The area of the composite area is 400 square millimeters.
