Answer:      Margin of Error = 1.944

                    Lower Bound = 3.052

Explanation:-

Attached below is a file for monthly Rate of return. Used an excel sheet to determine the confidence interval which seems relatively easier as compared to manual computation. The range below (A2:A40) shows the monthly

Functions used : Standard Deviation as= STDEV (A2:A40)

                             Sample Mean = AVERAGE(A2:A40)

                             Margin of Error = CONFIDENCE.T(D4,D5,D2)

                              Lower Bound Interval = D6-D7 = -3.052

Simplify: 11y-110/50-5y
alexandr1967 [171]
<h2>Answer:</h2>\frac{11y-110}{50-5y}=-\frac{11}{5}

<h2>Explanations:</h2>

Given the following expression show below;

\frac{11y-110}{50-5y}

Factor out the GCF from both the numerator and denominator

\frac{11(y-10)}{5(10-y)}

This can also be expressed as;

\begin{gathered} \frac{11(-10+y)}{5(10-y)} \\ \frac{-11(10-y)}{5(10-y)} \end{gathered}

Cancel out the common expression

\frac{-11\cancel{(10-y)}}{5\cancel{(10-y)}}=-\frac{11}{5}

Hence the simplified form of the expression is -11/5

Answer:

No, these triangles are not similar.

Step-by-step explanation:

Similar triangles have the same angle measures.

Knowing that the angles in a triangle add up to 180 degrees, find the missing angle, and you will see that the angles in the triangle are not congruent to each other, meaning that the triangles are not similar.

STALIN [3.7K]

Answer:

\frac{7}{10}  of voting age population voted

Step-by-step explanation:

In order to find out that fraction we just have to mulitply the fraction of the people that were registered by the fractions of the people that were registered and voted. And so we get...

(\frac{4}{5})(\frac{7}{8}) = \frac{(4)(7)}{(5)(8)} = \frac{28}{40} = \frac{7}{10}
