   1,680
÷ 400
= 4.2   Xian has completed 4.2 LAPS of the track,

  400
x  14
= 5,600  So this is the total amount of yards in the track

  5,600
- 1,680
=3,920 So this is how many yards are left for Xian to run

  3,920
÷   400
= 9.8  This is how many laps Xian has to run

4.2 + 9.8 = 14

so estimating how many laps Xian has run compared to how many he has left, he has completed 30% of the track.

Ernesto solves the equation below by first squaring both sides of the equation. \sqrt{\dfrac{1}{2}w+8}=-2 2 1 ​ w+8 ​ =−2square
algol [13]

Answer:

<h2>w = -8</h2>

Step-by-step explanation:

Given the equation solved by Ernesto expressed as \sqrt{\dfrac{1}{2}w+8}=-2, the extraneous solution obtained by Ernesto is shown below;

\sqrt{\dfrac{1}{2}w+8}=-2\\\\square\ both \ sides \ of \ the \ equation\\(\sqrt{\dfrac{1}{2}w+8})^2=(-2)^2\\\\\dfrac{1}{2}w+8 = 4\\\\Subtract \ 8 \ from \ both \ sides\\\\\dfrac{1}{2}w+8 - 8= 4- 8\\\\\dfrac{1}{2}w= -4\\\\multiply \ both \ sides \ by \ 2\\\\\dfrac{1}{2}w*2= -4*2\\\\w = -8

Hence, the extraneous solution that Ernesto obtained is w = -8

1.15 GPA and study hours: A survey was conducted on 193 Duke University undergraduates who took an introductory statistics cours
KonstantinChe [14]

Answer:

Step-by-step explanation:

A

According to the exercise we can say that the explanatory variable will be hours / weeks of study.

The response variable is GPA.

B

We definitely found that between the variables there is a weak or fragile relationship, neither negative nor positive nor linear.

C)

1.Observational study, since we observe that the only variables that will influence the results of the study are the observations of the students

2.No. This study is observational and its characteristics are not sufficient to conclude that studying more hours leads to obtaining a higher GPA.

Help me from 6-9 (geometry)
elena55 [62]

Answer:

6) Two angles are called supplementary when their measures add up to 180 degrees. For example, two right angles are supplementary angles.

7) When the sum of two angles is equal to 90 degrees, they are called complementary angles. For example, 30 degrees and 60 degrees are complementary angles.

8) you have to plot the points on the graph and draw a line and label it with L at one point and M at another point.

9) x = 20

m < A = 65

m < B = 25

Step-by-step explanation:

9)

3x + 5 + 2x - 15 = 90

3x + 2x + 5 - 15 = 90

5x - 10 = 90

5x - 10 + 10 = 90 + 10

5x = 100

5 / 5x = 100 / 5

x = 20

A = 3x + 5

A = 3(20) + 5

A = 60 + 5

A = 65

B = 2x - 15

B = 2(20) - 15

B = 40 - 15

B = 25
