it is 282.24

this is the plus sign:  +

Multiply decimals the same way that you multiply whole numbers. Put as many decimal places in your answer (that is, behind the decimal point) as there were in the two numbers that you multiplied (in both of them together).

For example:  12.34 x 5.1;    1234 x 51  =  62934  and, since there were two decimal places in the first number and one decimal place in the second number, there will be three (one + two) decimal places in the answer:

    12.34 x 5.1  =  62.934

Another example:  34.56 x 0.000007  =  0.00024192

because 3456 x 7  =  24192 and, since there were two decimal places in the first number and six decimal places in the second number, there will be two + six= eight decimal places in the answer.

Questions?

The square root of your face = √face -> √(your*mom) = ∑Stop+asking/stupid+question = 12

Hope it helps :)

The probability of getting a test statistic of at least 1.08 is (approximately) 0.14.

If you are testing the claim that p < 0.06, the answer is "no"; however, if you are testing the claim that p > 0.06, the answer is "yes". 

Usually, the claim is that p < some value, not > some value.

(4x² - 16x + 7) / (x² - 4x + 4)  >  3

Multiply both sides by  x² - 4x + 4:

4x² - 16x + 7  >  3(x² - 4x + 4)

4x² - 16x + 7  >  3x² - 12x + 12

Subtract  3x² - 6x + 12 from both sides:

x² - 4x - 5  >  0

(x - 5)(x + 1) > 0

Either  both x - 5 and x + 1 are positive   or  both x - 5 and x + 1 are negative.

If  x - 5 > 0  and  x + 1 > 0   --->   x > 5  and  x > -1   --->   x > 5

If  x - 5 < 0  and  x + 1 < 0   --->   x < 5  and  x < -1   --->   x < -1

Answer:  x < -1  or  x > 5

2x-3y=6

To find the y intercept, let x = 0....so.....-3y = 6  →  y = -2  ... so (0, -2) is on the graph

To find the x intercept, let y = 0......so....  2x = 6   →   x = 3  ....so (3, 0)  is on the graph

Now......just plot the points on a graph and draw a line through them....

I am ging to finsh up in a minute so I'll show you a little more to make sure you can at least start

$$\left({\frac{{\mathtt{2}}}{{\mathtt{z}}}}{\mathtt{\,-\,}}{\mathtt{1}}\right){\mathtt{\,-\,}}{\frac{{\mathtt{1}}}{{\mathtt{4}}}} = {\frac{{\mathtt{3}}}{\left({\mathtt{z}}{\mathtt{\,\small\textbf+\,}}{\mathtt{1}}\right)}}$$

$$\\\frac{2}{z}-1 -\frac{ 1}{4}\right = \frac{3}{(z+1)}\\\\
\frac{2}{z}-\frac{ 5}{4}\right = \frac{3}{(z+1)}\\\\
4z(z+1)\left[\frac{2}{z}-\frac{ 5}{4}\right] = 4z(z+1)\frac{3}{(z+1)}\\\\
4z(z+1)\frac{2}{z}-4z(z+1)\frac{ 5}{4} = 4z(z+1)\frac{3}{(z+1)}\\\\
4\not{z}(z+1)\times \frac{2}{\not{z}}-\not{4}z(z+1)\frac{ 5}{\not{4}} = 4z\times \frac{3}{1}\\\\
8(z+1)-5z(z+1) = 12z\\\\$$

etc

((2a)/b)^(-5).......notice that we can re-write this as....

(b / (2a)) ^(5)     ...so we have...

b^5 / [2^5  * a^5] =

(1/32)(b/a)^5

I have added to my answer above :)

$$\left({\frac{{\mathtt{2}}}{{\mathtt{z}}}}{\mathtt{\,-\,}}{\mathtt{1}}\right){\mathtt{\,-\,}}{\frac{{\mathtt{1}}}{{\mathtt{4}}}} = {\frac{{\mathtt{3}}}{\left({\mathtt{z}}{\mathtt{\,\small\textbf+\,}}{\mathtt{1}}\right)}}$$. yes

(2/z-1) - 1/4 = 3/(z+1)

this is what you have asked for is it what you want?

$$\left({\frac{{\mathtt{2}}}{{\mathtt{z}}}}{\mathtt{\,-\,}}{\mathtt{1}}\right){\mathtt{\,-\,}}{\frac{{\mathtt{1}}}{{\mathtt{4}}}} = {\frac{{\mathtt{3}}}{\left({\mathtt{z}}{\mathtt{\,\small\textbf+\,}}{\mathtt{1}}\right)}}$$

anyway if it is firstly recognise that z cannot be 0 or -1

Simplify the LHS 

then

multiply both sides by   4z(z+1)

that will get rid of all the fractions and make it easy to work with.   

give it a go and if you get stuck or need more help then show us what you've done or ask us to help more.

that's fine - I think we were both doing it at the same time :)

Hint ..... 2 + 1/8   = 17/8     and  3 + 1/6 = 19/6

Can you finish???

Sorry, Melody.......I didn't mean to steal your thunder.....!!!

l 4x - 1 l = 4

Note that  we just need to solve two equations here

4x - 1  = 4       and  -(4x - 1)  = 4  →  4x - 1  = -4

Can you take it from here??

you just have to solve 2 equations 

4x-1=4  and   4x-1=-4

there will be 2 answers.   

Ah, shania.....I missed the "at least half" part.......but, "at least half" means "4 or more"....NOT that we have to have 5 cups filled....!!!

This eliminates the third option.....since only 3 cups in the first row are filled.

Notice that your answer - adding two in the first row and 4 in the second row -  isn"t listed as one of the original options....!!!

Under the "at least" constraint......I'll amend my answer to the first option.....= (4/8)(4/8) = 16/64 =  25%

Do you want to do this by hand

or on the site calc

or on a different calc?

There are 12 months in a year so multiply by 12
