Answer: <em>1.1 × 10⁸ cm³</em>


Explanation:


1) Since the ball is spherical, you use the volume formula for a sphere, which is:


Volume = [4/3] π r³


2) r is the radius, which is given and is equal to 3×100cm = 300cm


3) Pluging in the value of r, you get:


Volume = [4/3] π (300 cm)³ = 113,097,335.53 cm³


4) Since, r = 3×100 cm has two significant figures, the result must show only two significant figures.


So, using scientific notation, the right answer must be reported as:<em> 1.1 × 10⁸ cm³</em>

The length is 2 feet longer than the width. The perimeter is 36 feet, what is the length?
SOVA2 [1]

Answer:

The length would be 10ft and the width would be 8ft

Step-by-step explanation:

For the purpose of this, we'll set the width as x. We can then define the length as x + 2 since we know it is 2 ft longer than the width. Now we can use those along with the perimeter formula to solve for the width.

P = 2l + 2w

36 = 2(x + 2) + 2(x)

36 = 2x + 4 + 2x

36 = 4x + 4

32 = 4x

8 = x

Now since we know that the width is 8ft, we can add 2ft to it to get the length, which would be 10ft.

What is the nth term rule of the linear sequence below? 15 , 7 , − 1 , − 9 , − 17 , . . .
Doss [256]

You can see that you're constantly subtracting 8 to get the next number. So, we have

a_1 = 15

a_2 = a_1-8

a_3 = a_2-8 = (a_1-8)-8=a_1-2\cdot 8

a_4=a_1-3\cdot 8

a_5=a_1-4\cdot 8

So, as you can see, to get the n-th term we must subtract (n-1) times 8 from the original number.

A college professor reports that students who finish exams early tend to get better grades than students who hold on to exams un
s344n2d4d5 [400]

Answer:

The correlation between exam score and amount of time spent on the exam is an example of a <u>negative correlation</u>.​

Step-by-step explanation:

Consider the provided statement.

College professor reports that students who finish exams early tend to get better grades than students who hold on to exams until the last possible moment.

That means the student who finish the exam early will get the highest marks. One who finish after the first student will get second highest mark and the one who finish in the end will get the least marks.

Now consider time as first variable and marks as second variable.

That means as the first variable increase the second variable decreases.

According to the definition of Negative correlation: It is a relationship between two variables in which one variable increases as the other decreases, and vice versa.

Hence, the correct answer is negative correlation.
