Answer:

a) Slope of the line m = ∞

b) Slope of the line m =0

Step-by-step explanation:

Explanation:-

Step(i):-

Given points are ( 7,7) and (7,-8)

Slope of the line

$m = \frac{y_{2} - y_{1} }{x_{2}-x_{1} }$

$m = \frac{-8-7 }{7-7 } = \frac{-15}{0} = infinite$

m = ∞

Step(ii):-

Given points are (-6,7) and (9,7)

Slope of the line

$m = \frac{y_{2} - y_{1} }{x_{2}-x_{1} }$

$m = \frac{7-7 }{9-(-6) } = \frac{0}{15} = 0$

Slope of the line m =0

40% of an hour in minutes and secs

olga55 [171]

Answer:

40% of an hour equals: 24 minutes

40% of an hour also equals: 1440 seconds

Skills needed: Time Units Conversion

Step-by-step explanation:

1) First, we need to understand how to convert between hours, minutes, and seconds.

There are 60 minutes in 1 hour ==> 1 hour = 60 minutes

There are 60 seconds in 1 minute ==> 1 minute = 60 seconds

- This means that there are 3600 seconds in 1 hour ( $60*60=3600$ )

- This also means that there are 60 minutes in 1 hour

2) We are trying to find how many minutes (or seconds) 40% of an hour is.

---> When converted to decimal, $40\%=\frac{40}{100}=0.4$

40% of an hour = 0.4 hours

Since there are 60 minutes in an hour, there are $60*0.4$ minutes in 0.4 hours. $60*0.4=24$ so, 24 minutes in 0.4 hours.

Since there are 3600 seconds in an hour, there are $3600*0.4$ seconds in 0.4 hours. $3600*0.4=1440$ so, 1440 seconds in 0.4 hours.

Aleksandr [31]

The question is incomplete. The complete question is :

Members of a research team are considering three studies related to sleep and learning. The first study involves comparing the scores on a post-study test of learning from two groups of randomly chosen adults, with one group getting at least 7 hours of sleep per night for a week and the other group getting at most 6 hours of sleep per night for a week. A second study involves asking a random sample of students at a large university to report the average number of hours of sleep they get each night and their college grade point average. A third study involves asking a random sample of high school students in a large school district whether they feel they get enough sleep to stay alert throughout the school day.

Which study appears to look for an association between two variables without actively manipulating either one. What are those variables ?

Solution :

The second study in the context is involved in asking for a random sample of the students at an university to provide a report the average hours of sleep that everybody get each night and also the grade point of their college appears for association between these two variables without actively changing either of one.

These variables are the grade point average of the students and the numbers of hours of sleep.

Help with the following attachment

GenaCL600 [577]

None of the answer choices makes any sense. (You should have your teacher show you how to select the correct choice.)

_____

Answers that are closer to the plotted points are ...

... A = -0.9, B = -9/16, C = -0.4, D = -1/16

The attachment shows these points plotted. As you can see, even these values aren't quite right.

Segment CW is congruent to segment MQ

Fiesta28 [93]

Answer:

The true congruence statement is CW ≅ MQ ⇒ 2nd answer

Step-by-step explanation:

All the radii in the circle are congruent

From the attached figure

In circle B

∵ W, C, Q, and M lie on the edge of the circle

∴ BW, BC, BQ, and BM are radii

∵ All the radii in the circle are congruent

∴ BW ≅ BC ≅ BQ ≅ BM

∵ CW ≅ MQ ⇒ Given

∴ The true congruence statement is CW ≅ MQ
