Answer:
<h2><u>
Graph A</u></h2>
Step-by-step explanation:
We know it must be graph A because when finding the most popularly bought item, the percentages only can go to 100%
So graphs C and D are eliminated.
Also since it never said any flavors were unknown, all the percents have to add up to 100%
So graph B is eliminated.
Only graph A follows the requirements
Answer:
Step-by-step explanation:
2x - 9y = 23
5x - 3y = -12x - 9y = 23we]periyhw[euiorghweuirtg7wuio[ryg
5x - 3y = -12x - 9y = 23
5x - 3y = -12x - 9y = 23
5x - 3y = -1

Answer: y = 3.5 x+ 43.8
Step-by-step explanation:
Here x represents the number of years after 1990
Thus, we get the table that is used to find the equation will be,
x 0 2 4 6 8
y 45 51 57 61 75
Let the equation that shows the above data,
y = b + a x ---------(1)
By the above table,
By substituting these values in the above value of a and b,
We get b = 43.8 and a = 3.5
Substitute this value in equation (1)
we get, the equation that shows the given data is,
y = 3.5 x + 43.8
⇒ Option (3) is correct.
The sum formula for a geometric sequaence is:
sum(n) = a1(1-r^n)/1-r
Where n is the number of terms, a1 is the first term and r is the common ratio:
s(8) = 3(1-1/2^8) / (1-1/2)
s(8) = 3(1-1/256) / 1/2
s(8) = 2 253/256 / 1/2
s(8) = 765/128
The answer is C.
