(1,3) and (-2,-6) are both solutions
Andrews [41]3 years ago

Substitute one by one and see which pair satisfy it.
(-1,3)
3=3(-1)
3=-3 
it is not true,so not a solution.
(2,5)
5=3×1
5=3 
it is not true so not asolution.
(1,3)
3=3×1
3=3
it is true so (1,3)is a solution.
(-2,-6)
-6=3×(-2)
-6=-6
which is true.
Hence (-2,-6) is also a solution.

What is the correlation coefficient for the data shown in the table?
xxTIMURxx [149]

Answer:

The correlation coefficient is -1

Step-by-step explanation:

Here, we want to get the correlation coefficient for the given dataset

from the table, what do we observe?

As x is increasing by 5 units;

y is decreasing by 5 units

What this mean is that there is a negative correlation between both

Thus, what we have here is that, since the rate of increase/decrease on both ends is of equal magnitude but opposite signs, we can conclude that the correlation coefficient is -1

14 over 15 rounded to the nearest tenth
NARA [144]

Answer:

0.9

Step-by-step explanation:

14/15 = 0.933333333  <u>IF:</u>

<u></u>

<u>1.</u><em> You first change it into a decimal by dividing the numerator by the denominator.</em>

<em>        </em>14 ÷ 15

<u>2.</u> <em>You will get a recurring decimal.</em>

<em>      </em>0.933333333

<u>3.</u><em> The first digit after the decimal is in the position of the '</em><u><em>tenths'</em></u>

      0.<u>9</u>

<u>4.</u><em> You should use only two digits after the decimal to calculate </em>

<em>       0.93</em>

<u>5.</u><em> Since the number 3 is less than five, it will change into a zero and get eliminated.</em>

<em>             ∴ The answer will be = 0.9</em>

Tran checked the time on his watch after he finished his daily run select the time that Tran finished running mark all that appl
Viefleur [7K]

Answer:

(a) and (b) are correct

Step-by-step explanation:

Given

See attachment for complete question

Required

Select the correct options

A clock is divided into two equal parts.

(1) 1 - 6

(2) 7 - 12

<em>When the hour hand is on (1), then the time is "after"</em>

<em>When the hour hand is on (2), then the time is "before"</em>

<em />

From the attached clock, we have:

(1) The hour hand on 9

(2) The minute hand 1 unit above 9 i.e. 46 minutes

(1) implies that, the time is before 9 i.e. past 8

(2) implies that the minutes is (60 - 46) before 9 or 46 minutes after 8

In (1) and (2) above, we have two interpretations.

1: (60 - 46) minutes before 9

This gives:

14 minutes before 9

2: 46 minutes past 8

i.e. 8 : 46
