Answer:
2046
Step-by-step explanation:
The sum of 2^0 to 2^x added is equal to 2^(x+1)-1 but because 2^0 isnt included its 2^11-2 or 2048-2
Hey there! :)
Answer:
a) Blue.
b) 1/2.
Step-by-step explanation:
Find the probabilities for each color:
Blue: 1/8
Yellow: 3/8
Green: 4/8 or 1/2
a) The color that the spinner is the least likely to land on has the smallest probability, which in this instance, is blue.
b) The probability of the spinner landing on green can be determined by:
# of green sections /total
Therefore:
4 / 8
Simplify the fraction:
4 / 8 = 1 / 2.
If you do 12.2-3.3 youll get your answer
Answer:
(-9,-3.4)
Step-by-step explanation:
By adding 2.1x and subtracting 5.3 from the top equation, it will end up as 2.1x=4y-5.3
By adding 5.5y to the bottom equation, it will end up as 2.1x=5.5y-0.2.
By the equal valuesmethod, they are equal: 5.5y-0.2=4y-5.3
5.5y+5.1=4y
5.1=-1.5y
y=-3.4; this gets us our y-coordinate.
To get the x-coordinate, you plug the value for y back into the original equation.
-2.1x-4y=5.3
-2.1x-4(-3.4)=5.3
-2.1x-13.6=5.3
-2.1x=18.9
x=-9
