Suppose our data set is:
2,4,6,8
the mean of the above data is:
(2+4+6+8)/4=20/4=5

Increasing the above value by 8
10,12,14,16
the mean will be:
(10+12+14+16)/4
=52/4
=13
The difference in the two mean values i
13-5=8
Thus we conclude that if we increase our values by 8, the mean increases by 8

on Saturday Leo and his brother drove into town to visit their mom Leo is trying to remember how much he spent on gas and tolls

Gwar [14]

Let t be the number of tolls they crossed.

Amount they spent at each toll = $1.75.

Amount they spent at gas station = $28.

Let C be the total amount they spent on gas and tolls.

If they crossed 1 toll, then

C = 28 + 1.75(1).

If they crossed 3 tolls, then,

C = 28 + 1.75(3)

If they crossed t tolls, then,

C = 28 + 1.75t

Here, the terms are 28 and 1.75t and the factors are 1.75 and t.

I am really confused about this question for math.. any help would be really appreciated:

Elina [12.6K]

$y= (\frac 1 4 )^x$

A reflection about the x axis, about y=0, is the mapping (x',y')=(x,-y) so

$y'= -y = - (\frac 1 4)^{x'}$

A dilation of 2 is the mapping (x'',y'')=(2x', 2y')

So

$x'=x''/2, y'=y''/2$

$y''/2= - (\frac 1 4)^{x''/2}$

$y'' = - 2((\frac 1 4)^{1/2})^{x''}$

$y''= - 2(\frac 1 2)^{x''}$

We can rewrite that without the primes and combine the powers of 2.

$y = - 2^{1-x}$

Let's graph these and see if we're close,

Plot y= (1/4)^x, y= - (1/4)^{x}, y = - 2^{1-x}

blsea [12.9K]

Answer:

20/36 = 5/9

Step-by-step explanation:

The fraction could be represented by ( # of pages that typed / # of total pages that has to type).

So

20 is number of pages that typed

36 is the total number of pages that has to types

20/36

Plz help me-7.1(z-1.1)

Elena-2011 [213]

Answer:

<h2>-7.1z +7.81</h2>

Step by step explanation:

$- 7.1(z - 1.1)$

Multiply each term in paranthesis by -7.1

$- 7.1 \times z - 7.1 \times ( - 1.1)$

Multiply:

$-7.1z + 7.81$

Hope this helps...

Good luck on your assignment..
