$-2(2x+9)\ \textgreater \ -4x + 9$

$-4x-18\ \textgreater \ -4x+9
$

$-18\ \textgreater \ 9
$ $\text{Cancel -4x from both sides}$

$\text{No Solution}$

-2(2x+9)>-4x+9
1)We solve this inequation:
-2(2x+9)>-4x+9
-4x-18>-4x+9
-4x+4x-18>9
-18>9 This is not true, because -18<9; Therefore this inequation is never true.

Answer: this inequation is never true.

Logan measured a line to be 7.4 inches long. If the actual length of the line is 7.7 inches, then what was the percent error of

Tanzania [10]

Answer:

4.0541

Step-by-step explanation:

I don't know if this is correct but this is what I got.

You would take the error and divide it by the theoretical value and then multiply that by 100.

7.7 - 7.4 = 0.3

0.3 ÷ 7.4 = 0.04054054

0.04054054 x 100 = 4.05405405 (simplify) = 4.0541%

Hope I helped in any way

Given Fig.is a triangle

Perimeter is simply sum of the all sides of a triangle

1/3x + 7/x^2 + (x+2)/x

=[ x+ 21 + 3x(x+2)]/3x^2

= (x+ 21 + 3x^2 + 6x)/3x^2

= (3x^2 + 7x +21)/3x^2

If a baseball player get a hit in 31% of his at-bats, what is the probability that he will

solong [7]

Given:

A baseball player get a hit in 31% of his at-bats.

To find:

The probability that he will get a hit 5 at-bats in a row.

Solution:

Since, a baseball player get a hit in 31% of his at-bats, therefore

Probability that he get a hit = $\dfrac{31}{100}$

= $0.31$

Now, the probability that he will get a hit 5 at-bats in a row is

$P=0.31\times 0.31\times 0.31\times 0.31\times 0.31$

$P=(0.31)^5$

$P=0.0028629151
$

Therefore, the required probability is $(0.31)^5$ and it can be written as 0.0028629151 .
