30 members....21 girls and 9 boys
ratio of girls to boys is : 21/9 which reduces to 7/3 or 7:3 or 7 to 3
First convert them to vertex form
first one is y = 2(x + 0.75)^2 - 6.125
2nd is y = -2(x - 0.75)^2 - 3.875
the -2 will cause a reflection of the first equation in the x axis . then a translation down of 6.125 + 3.875 = 10 units , followed by
a translation of -0.75-0.75 = -1.5 units to the right = 1.5
Answer: Score is 629
Step-by-step explanation: z value for P(x > 0,90) is 1,29
Average x is 500 and deviation is 100. Value of score p is solved from
z = (p - x) / s p = s·z· + x = 129 + 500 = 629
Answer:
g(f(3)) = 49
Step-by-step explanation:
Evaluate f(3), then substitute the value obtained into g(x) , that is
f(3) = 2(3) + 1 = 6 + 1 = 7, then
g(7) = 7² = 49
Answer: B Linear
Step-by-step explanation:
It wouldn't be exponential because there isn't exponent, and it won't be rational because there is no fraction, and it is not quadratic. Hope this helps :)
