In a survey of 5100 randomly selected T.V. viewers, 40% said they watch network news programs. Find the margin of error for this
horsena [70]

Answer:

Margin of error = 0.01344

Step-by-step explanation:

Margin of error = critical value × standard deviation.

critical value for 95% confidence interval = 1.96

Standard deviation = √[(p)(q)/n]

p = 0.4, q = 1 - p = 1 - 0.4 = 0.6, n = 5100

Standard deviation = √[(0.6×0.4)/5100] = 0.00686

Margin of error = 1.96 × 0.00686 = 0.0134

1/3 +1/6 in fraction form<br>​

\Large\texttt{Answer}

\bf{\cfrac{1}{2}}

\overline{\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad}

\Large\texttt{Process}

Do you remember that we cannot add fractions when they have unlike denominators? We can onyl add fractions as long as they have the same denominator!

So here's the big idea: fractions must have the same denominator.

If we multiply the first fraction by 2, then both fractions will have the same denominator. *

* <em>Why 2??</em>

<em />

-  Because:

We need to find the least common multiple of 3 and 6, which is 6. Next, what should 3 be multiplied by to result in 6? That's right, 2.

Also, we can only multiply the denominator by 2 as long as we multiply the numerator by 2!

So that's why we multiply the whole fraction by 2

\bf{\cfrac{1\times2}{3\times2}+\cfrac{1}{6}}

Watch what happens

\bf{\cfrac{2}{6}+\cfrac{1}{6}}

Add the numerators

\bf{\cfrac{2+1}{6}}

\bf{\cfrac{3}{6}}

Simplifying the fractions

\bf{\cfrac{3\div3}{6\div3}}

\bf{\cfrac{1}{2}}

Hope that helped

Someone help me solve
Lady_Fox [76]
First draw sloping up (steep because he’s running)to the right until you hit 20 on the y axis. Next draw down and to the right for 5 yards until 15 on y axis. Next is a flat horizontal line for 3 seconds on x axis. Finally a shallow slope line down (because he is walking) and right until you hit the x axis.

Step-by-step explanation:

Combine like terms, perform the operations with the coefficients of the variable, then write the variable.

10r - 5r + 3r - 8r

= 5r + 3r - 8r

= 8r - 8r

= 0
