Answer:

The approximate number of gallons of water that flow over the waterfall in 1 day is:

  • <u>A. 5.59 x 10^10</u>

Step-by-step explanation:

To obtain the answer to the question, you must multiply the number gallons of water flow over a waterfall each second (6.5 x 10^5 gal/s) by the number of seconds in a day (8.6 x 10^4 s), as I show you below:

  • Gallons of water that flow over the waterfall in 1 day = Number of gallons * Number of seconds in a day.
  • Gallons of water that flow over the waterfall in 1 day = 6.5 x 10^5 gal/<u>s</u> * 8.6 x 10^4 <u>s</u>

Now, we must cancel the seconds, then:

  • <u>Gallons of water that flow over the waterfall in 1 day = 5.59 x 10^10 gallons</u>

How you can see, <em>once you have multiplied these two values, the answer is the same to the option A</em>.

A 90 percent confidence interval for the slope of a regression line is determined to be (-0.181, 1.529). Which of the following
GenaCL600 [577]

Answer: a. The correlation coefficient of the data is positive.

Step-by-step explanation:

Estimated slope of sample regression line  = \dfrac{Upper \ limit + lower\ limit}{2}

Here , confidence interval :  (-0.181, 1.529)

Estimated slope of sample regression line  = \dfrac{-0.181+1.529}{2}

=\dfrac{1.348}{2}\\\\=0.674\ \ \ \ [\text{ positive}]

⇒Correlation coefficient(r) must be positive, So a. is true.

But, d. and e. are wrong(0.674 ≠ 0 or 1.348).

We cannot check residuals or its sum from confidence interval of slope of a regression line, so b is wrong.

We cannot say that scatterplot is linear as we cannot determine it from interval, so c. is wrong

So, the correct option : a. The correlation coefficient of the data is positive.

1 question. A big square is made up of 4 identical small squares the area of each small square is 25 cm A. Find the length of ea
Bogdan [553]

Answer:

50cm

200cm

50cm^2

Step-by-step explanation:

The big square is divided into 4 with a side length of 25cm. 2 small square side lengths make up the big squares.

25 * 2 =

50cm

50 + 50 + 50 +50 =

200

15 +2

17

8 + 2

10

17 * 10 = 170

15 * 8 = 120

170-120 = 50

50cm^2
