Lines l, m, and n are parallel. What is the value of x?

kompoz [17]

Since the lines are parallel, the angles created with lines l and n are equivalent. So if you find the angle for line l,
180°-46°=134°
that is also your angle for x

8x2 +43x +30=0solve for x

storchak [24]

Use the quadratic formula to find the values of x:

$x=\frac{-b\pm\sqrt[]{b^2-4ac}}{2a}$

Where a, b and c are the coefficients of the quadratic equation.

$\begin{gathered} x=\frac{-43\pm\sqrt[]{43^2-4\cdot8\cdot30}}{2\cdot8} \\ x=\frac{-43\pm\sqrt[]{1849-960}}{16} \\ x=\frac{-43\pm\sqrt[]{889}}{16} \end{gathered}$

The equation has two solutions for x.

$\begin{gathered} x1=\frac{-43+\sqrt[]{889}}{16} \\ x2=\frac{-43-\sqrt[]{889}}{16} \end{gathered}$

As decimal numbers:

$\begin{gathered} x1=-0.8239 \\ x2=-4.5510 \end{gathered}$

In a survey of 302 registered voters, 167 of them wished to see Mayor Waffleskate lose her next election. Find a point estimate

Ivahew [28]

Answer:

A point estimate for the proportion of registered voters who wish to see Mayor Waffleskate defeated is of 0.553.

Step-by-step explanation:

Point estimate:

The point estimate of a proportion is the sample proportion(number of desired outcomes divided by the number of total outcomes).

Find a point estimate for the proportion of registered voters who wish to see Mayor Waffleskate defeated.

167 out of 302. So

$p = \frac{167}{302} = 0.553$

A point estimate for the proportion of registered voters who wish to see Mayor Waffleskate defeated is of 0.553.
