Answer:

1. cannot be simplified anymore

2. 1/3

3. 1/9

4. cannot be simplified anymore

5. cannot be simplified anymore

6. cannot be simplified anymore

Step-by-step explanation:

1. It can't be because 9 can only be done with 3 and 32/3 is not a whole number so it cannot be simplified.

2. It is 1/3 because 15 can be simplified down in both of them because 45/15=3.

3. It is 1/9 because 2/2=1 and 18/2=9.

4. It cannot be simplified because 7 is not able to be multiplied besides 1 and 7.

5. It cannot be simplified because 7 is not able to be multiplied besides 1 and 7.

6. It cannot be simplified because 5 can only be multiplied by 1 or 5.  44/5 would not be a whole number so you can't simplify it anymore than that.

Find the equation of the line I in the following picture. The shapes under the lines are squares
julia-pushkina [17]
If you look carefully at the graph, you may see that the slope of the line is
          3-4           -1
---------------- = ------ = m
         7-4             3

thus, you have the slope of the line and two points on the line.  Suppose we
choose the point (4,4) and subst. the known slope and the coordinates of this point into the point-slope formula for the eqn of a str line:

y-y1 = m (x-x1)

y-4 = (-1/3)(x-4)

This is the desired equation.  You could, if you wished, change this into slope-intercept form.

In politics, marketing, etc. we often want to estimate a percentage or proportion p. One calculation in statistical polling is t
klemol [59]

Answer:

The conclusion about p using an absolute value inequality is  

   0.325  <  p <  0.375

Step-by-step explanation:

From the question we are told that

   The  sample proportion is  \r p =  0.35

    The  margin of error is  E =  0.025

The confidence interval is mathematically represented as

           \r p  -E  <  p <  \r p +E

=>        0.35 - 0.025 <  p <  0.35 + 0.025

=>      0.325  <  p <  0.375

Which expression is equal to (−4x2−1)(2x2+3)?
Leya [2.2K]

Answer:

The first one:

−8x4−14x2−3

Step-by-step explanation:

(-4•2-1)(2•2+3)

-4•2 = -8

-8 - 1 = -9

(-9)(2•2+3)

2•2 = 4

4+3 = 7

(-9)(7) = -63

Now we find the one that equals -63:

-8•4-14•2-3

(-8•4)-14•2-3

-32-14•2-3

-32-(14•2)-3

-32-28-3

(-32-28)-3

-60-3

-60-3 = -63

BAM! THE ANSWER!

Please help me this is important
Dmitrij [34]

Answer:

C. II, III, and IV only

Step-by-step explanation:

Lol I haven't done one of these in a while, so thanks for the practice!

It's important to note that a dilation does NOT change the angles of the shape whatsoever. By this, you know that II and III are automatically correct, which rules out A and B. After that, you can look at I, which is the only difference between C and D. Since the dilation factor is 2/3, the parallelogram you see is smaller than the original. Since in I, the original would be larger than the denominator, the correct answer would be at least greater than one (to be precise, it'd be 3/2). To make everything easier, you can find the value by assigning the original side a value of 1, which would make the prime value 2/3. 1/(2/3) is going to be 3/2.
