Answer:
291.87 is a rational number.
Step-by-step explanation:
Rational numbers are those numbers that can be expressed in fractions that is can be written as 
where p and q are integers and 
.
Consider the given number 291.87
Rewrite the decimal number as a fraction with 1 in the denominator, we get,
Multiply to remove 2 decimal places. Here, you multiply top and bottom by 10² = 100
Thus, the above fraction can be written as,
Thus, 291.87 is a rational number.
Answer:
J(0,2)
Step-by-step explanation:
When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite (its sign is changed). If you forget the rules for reflections when graphing, simply fold your paper along the x-axis (the line of reflection) to see where the new figure will be located.
Answer:
B. 5x³ + 2x -1
Step-by-step explanation:
(f +g)(x) = f(x) + g(x)
= 5x³ - 2 + 2x + 1
= 5x³ + 2x -1
Answer:0.124
Step-by-step explanation:
Using binomial distribution,
p =1-0.55=0.45
q = 0.55
n = 25
P( x=13) = 25 combination 13 x 0.55^12×0.45^ 13
= 0.124
