There are 25 grandparents there were in the survey. 4 prefered digital copies, 21 prefered hard copies. 

4/25 prefered digital copies
21/25 prefered hard copies

21 is more than 4. 
The only one of the possible answers that imply that more people prefered hard copies was the third option. Therefore, "More grandparents prefer using a hard copy than a digital copy." is the correct answer.

I would say you could definitely  eliminate number 1 because 4 and 21 are not the same . Lets go to number 2 now that might not be possible  so lets check it out just to check so 21 grandparents for hard copy is not less than the grandparents that want to use digital copy which is 4 so we cross that out. Number 3 is your answer because we can tell since 21 grandparents want to use a hard copy than digital therefore that is your answer 21 is greater than 4

What is 5.6 equalivent to
Sloan [31]
(this is for fractions!!!!!!!!!!!!)  28/5 or 5 3/5

i think u just make it into 5.6/1 multiply by 10 which gets 56/10 and wala 
but it's not simplified. 56 and 10 is divisible by 2 so u get 28/5 which is actually 5 3/5 (which is 5.6!!)

What are two things you will need to write an equation for a line?
vlabodo [156]

Answer:

Slope and y intercept.

Step-by-step explanation:

This is necassary to write the equation of a line in y=mx+b

m is where the slope goes, and b is the y intercept.

Alternatively, you could also write the equation for a line with a point on the line and the slope.

You would then write it in point slope formula:

y-y1=m(x-x1)

This can later be converted into slope intercept form.

Find an expression for the nth term ( tn ) in each of the following sequences:
Alexandra [31]

Answer:

The expression for the nth term is Tn = 8n -7

Step-by-step explanation:

Here, we are to find an expression for the nth term of the sequence.

Mathematically, the nth term of an arithmetic sequence can be expressed as;

Tn = a + (n-1)d

for T2, the equation is

a + d = 9

for T4, the equation is

a + 3d = 25

we can substitute the equation of T2 into T4 but we first need to rewrite T4

a + d + 2d = 25

9 + 2d = 25

2d = 25 -9

2d = 16

d = 16/2

d = 8

now since a + d = 9

a = 9-d

a = 9-8

a = 1

So the expression for the nth term would be;

1 + (n-1)8

1 + 8n - 8

= 8n -8+1

= 8n -7
