Answer:
Find out what x should be the apply by the power of 2 then you should be good
Answer: b=13, t=29
Step-by-step explanation:
Substituting the first equation into the second,

The actual probability of having odd is 3/6=1/2
so no of odds theoretically is 250
but it is 325
so, experimental is higher than theoretical
so answer is B !
and you can go for that !
Answer:

Step-by-step explanation:
slope=(y2-y1)/(x2-x1)
7-5/9-4
2/5
Complete theh square
isolate x terms
factor out coefient of x^2 term
take 1/2 of 1st degree coefient and square it, add positive and negative inside parnthasees, expand
f(x)=(2x^2+12x)+7
f(x)=2(x^2+6x)+7
6/2=3, 3^2=9
f(x)=2(x^2+6x+9-9)+7
f(x)=2((x+3)^2-9)+7
f(x)=2(x+3)^2-19+7
f(x)=2(x+3)^2-12
