A researcher wants to determine whether the rate of water flow (in liters per second) over an experimental soil bed can be used

pantera1 [17]

Here we are given the specific equation of:

amount of eroded soil = 0.4 + 1.3 x

where x is the flow rate

A linear equation has a general formula in the form of:

y = m x + b

where m is the slope and b is the y intercept of the equation

If we compare this with our specific equation, we can see that the slope and y intercept are both positive with values:

m = 0.4

b = 1.3

Therefore this only means that as the flow rate increases, the amount of eroded soil also increases.

Hence the correlation must be positive but we cannot solve for the exact value since we need the data for x and y.

Answer:

positive, but we cannot say what the exact value is

Halle has 36 feathers, 48 acorns, and 60 agates. She wants to put all of these items into bowls with the same number of feathers

Zielflug [23.3K]

To find the answer to this question, you simply find the greatest common factor.

All of these numbers have many factors, like 1, 2, 3, 4, and 6.

The greatest common factor is 12.

36, 48, and 60 can all be divided by 12 with no leftover or decimals. There is no higher common factor.

The maximum number of bowls she can put the items into is 12 bowls.

I hope this helps :)

I have a past due balance of 87.50 and my new charges are $75 I was also charged a late fee of 15% of my past due balance what i

Murljashka [212]

Your new total would be 177.5 because if you add the past due balance and add the charge of $75 and then add the 15% late fee you would get 177.5

87.50 + $75 + 15% = 177.5

Hopefully this right, if it is not i am so very sorry, Have a Good Evening:) ~Nana~!

The frequency distribution of weights (in kg) of 40 persons is given below.

gregori [183]

Answer: (a) 4

(b) 5

(c) 14

(d)

Class interval Class mark

30 - 35 $\dfrac{35+30}{2}=32.5$

35 - 40 $\dfrac{35+40}{2}=37.5$

40 - 45 $\dfrac{40+45}{2}=42.5$

45 - 50 $\dfrac{45+50}{2}=47.5$

50 - 55 $\dfrac{50+55}{2}=52.5$

Step-by-step explanation:

The data of 40 persons is given as :

Weights (in kg) Frequency

30 - 35 6

35 - 40 13

40 - 45 14

45 - 50 4

50 - 55 3

(a)

Lower limit is the lowest number in a class interval .

So, is the lower limit of fourth-class interval (45 - 50) is 4.

(b)

Class size = Upper limit - lower limit

So, Class size of first class interval = 35-30=5

Thus , class size of each interval is 5. [ class size remains same]

(c)

Highest frequency in table = 14 which is corresponding to 40 - 45 .

Thus , 40 - 45 is the class interval has the highest frequency.

(d)

Class mark is the mid value of each class interval.

Class interval = $\dfrac{(\text{Upper limit+Lower limit})}{2}$

Class interval Class mark

30 - 35 $\dfrac{35+30}{2}=32.5$

35 - 40 $\dfrac{35+40}{2}=37.5$

40 - 45 $\dfrac{40+45}{2}=42.5$

45 - 50 $\dfrac{45+50}{2}=47.5$

50 - 55 $\dfrac{50+55}{2}=52.5$
