Question: The sample data and the scatter plot was not added to your question. See the attached file for the scatter plot.

Answer: Yes

Step-by-step explanation:

From scatter plot, it was discovered that there is a linear relationship between the two variables and both variables are quantitative.

Therefore, it appropriate to use the correlation coefficient to describe the strength of the relationship between​ "Time" and​ "Fish Quality"?

Put these measurements in order from largest to smallest: 9000ml, 0.048 kl, 4.8L
Helen [10]

As the highest measurement unit given is KL, we will convert the other values to KL to arrange from largest to smallest or descending order.

Converting the given values we get:

9000 ml =  0.009 KL

4.8 L = 0.0048 KL

Third given is 0.048 KL

So, now arranging them from largest to smallest we get,

0.048 KL, 0.009 KL, 0.0048 KL

Hence the correct order is:

0.048 KL, 9000 ml, 4.8 L

Reptile [31]

Answer:

Yes, 10.5 cm, 8.0 cm and 4.0 cm can be the side lengths of a triangle.

Step-by-step explanation:

We have been given three lengths as 10.5 cm, 8.0 cm and 4.0 cm. We are asked to determine whether these side can be the side lengths of a triangle.

We will use triangle inequality theorem to solve our given problem.

Triangle inequality theorem states that sum of two sides of a triangle must be greater than 3rd side. Using triangle inequality theorem we will get 3 inequalities as:

10.5+8.0>4.0

18.5>4.0       True

8.0+4.0>10.5

12.0>10.5     True

10.5+4.0>8.0

14.5>8.0  True

Since all the three side lengths satisfy triangle inequality theorem, therefore, 10.5 cm, 8.0 cm and 4.0 cm can be the side lengths of a triangle.

A bond quote of 82.25 in dollars is equal to?
anastassius [24]
<span>A bond quote of 82.25 dollars is equals to:
=> 82.25/100 = 0.8225, this is the decimal value of the given number, now, the place value is ten thousands, thus we will multiply this by 10 000. 8 is tenths, 2 is hundredths, 2 is thousands, and 5 is ten thousands,
=> 0.8225 x 10 000
=> 8 225 dollar.
Thus, the bond quote of 82.25 has the value of 8 225 dollars to be exact.

At smith’s Mountain Lake Boat Rentals, it cost $25 per hour to rent a pontoon boat, plus a one-time
sergey [27]

Answer:

Jones family paid a total of $139

Step-by-step explanation:

Smith's Mountain Lake Boat provides Rental services that can be expressed as follows;

Total cost=cost per hour×number of hours rented+one time cleaning deal

For Benael's family;

Benael family total cost=Cost per hour×number of hours rented+one-time cleaning deal

where;

Benael family total cost=$226.50

Cost per hour=$25

Number of hours rented=11 am-6:30 pm=7 hours 30 minutes=7.5 hours

One time cleaning deal=x

Replacing;

226.50=(25×7.5)+x

187.5+x=226.50

x=226.50-187.5

x=39

One time cleaning deal=$39

For Jones family;

Jones family total cost=Cost per hour×number of hours rented+one-time cleaning deal

where;

Cost per hour=$25

Number of hours rented=9 am-1 pm=4 hours

One time cleaning deal=$39

Replacing;

Jones family total cost=(25×4)+39

Jones family total cost=$139

Jones family paid a total of $139
