Answer:
62:93

Explanation:
The question states that the number of students who want iced tea is 62.

To find out the total number of students, we must add both the number of students who want iced tea AND the number of students who want lemonade:

62+31=93

Therefore, the ratio of the number of students who want iced tea to the total number of students is 62:93.

I hope this helps!

Since the margin of error is 5%, the minimum of supporters will be less than the maximum of disapprovers.

So the third option will be correct. You cannot make certain conclusions based on this survey.

Which table contains the vertex of the graph represented by y=x^2-6x+4?

notka56 [123]

Answer:

Table B

Vertex is (3,-5)

Step-by-step explanation:

We are given with an equation of a parabola $y=x^2-6x+4$

Let is convert it into standard form of a parabola

$y=x^2-6x+4$

adding and subtracting 9 in the right hand side of the =

$y=x^2-6x+9-9+4$

$y=x^2-2\times 3\times x+ 3^2-9+4$

the first three terms of the right hand side forms the expression of square of difference

$a^2-2 \times a \times b+b^2 = (a-b)^2$

Hence

$y=(x-3)^2-5$

adding 5 on both sides we get

$(y+5)=(x-3)^2$

Comparing it with the standard equation of a parabola

$X^2=4\times \frac{1}{4} \times Y$

where $X=x-3$ and $Y=y+5$

The vertex of $X^2=4\times \frac{1}{4} \times Y$ will be (0,0)

and thus vertex of

$(y+5)=(x-3)^2$ will be (3,-5)

Hence the Table B is our right answer

1/2+1/9Please help me

musickatia [10]

<em>If the fraction whose denominator are equal then they will add up</em>

In the given fraction 1/2 +1/9, the denominator of both the fraction 1/2 & 1/9 is not same

so, to make the base same we take the LCM of the 2 & 9

$\begin{gathered} \text{LCM of 2 \& 9 is 18} \\ Si,\text{ the fraction will be :} \\ \frac{1}{2}+\frac{1}{9}=\frac{9+2}{18} \\ \frac{1}{2}+\frac{1}{9}=\frac{11}{18} \end{gathered}$

Answer : 11/18
