**Answer with explanation:**

In Inferential Statistics,maximum number of times data is read to find or deduce the Correct Information about the data set ,with the help of Different Measures of variation or for the particular kind of information.And then the old Hypothesis about the Data set is being tasted and if found incorrect, remedial measures are taken, that is it can be altered and Correct Hypothesis is Structured.

→Data Set is about : Average life of Different Bulbs

→Measure of Variation : Mean

→Phase of inferential statistics:** Data Analysis **

**Data Analysis ,that is with the help of mean,average life of bulb-lifetime data is gathered.**

**Answer:**

A) -3

**Step-by-step explanation:**

the coefficient of the 'x' term represents the slope

B) 70t

Because for every 1 min there are 70 magazines printed

<u>**Question**</u>:

Carmen is an engineer making plans to run a rail line, represented by the transversal t, through a city.

Examine Carmen’s rail plans to identify the measure of ∠1. The streets represented by lines V and W are parallel.

What is the m∠1?

25°

35°

145°

155°

The image of the plan is attached below.

<u>**Given**</u>:

The streets represented by lines V and W are parallel.

We need to determine the measure of ∠1.

<u>**Measure of ∠1:**</u>

When two parallel lines are crossed by the transversal line, the angles in the matching corners is called as corresponding angles. And the measure of the corresponding angles are always equal.

From the figure, the ∠1 and the other angle in the parallel line V with the measure of angle 155° are corresponding angles.

Thus, the **measure of ∠1 is 155°**

Hence, **Option D is the correct answer.**
