What is the simplest form of 6/18

2 answers:

6 0

All you have to do is divide both numbers (ones they both can go in).

Let's try 2.
$6/2=3\\18/2=9$

We get $\frac{3}{9}$ .

A number still can go into both numbers evenly.
3 can go into both numbers.

$3/3=1\\9/3=3$
We finally get $\frac{1}{3}$ .

Hope this helped :)

To convert a fraction into simplest form, we divide both the numbers by their HCF

HCF of both these numbers is 6.

Thus we divide them by 6

6/6 = 1
18/6 = 3

Thus the answer is 1/3

Is my answer correct? 10 points + brainleist!

Liono4ka [1.6K]

Answer:

your answer is incorrect. The correct answer is $h=-13$ and $k=13$ .

Step-by-step explanation:

If a quadratic function is $f(x)=ax^2+bx+c$ and a>0, then minimum value of the function at point $\left(-\dfrac{b}{2a},f(-\dfrac{b}{2a})\right)$ .

The given function is

$f(x)=x^2+bx+182$

Here, a=1, b=b and c=182. So.

$-\dfrac{b}{2a}=-\dfrac{b}{2(1)}=-\dfrac{b}{2}$

Put $x=-\dfrac{b}{2}$ in the given function to find the minimum value of the function.

$f(-\dfrac{b}{2})=(-\dfrac{b}{2})^2+b(-\dfrac{b}{2})+182$

We know that minimum value is 13. So,

$13=\dfrac{b^2}{4}-\dfrac{b^2}{2}+182$

$13-182=-\dfrac{b^2}{4}$

$-169=-\dfrac{b^2}{4}$

$169\times 4=b^2$

Taking square root on both sides.

$13\times 2=b$

$b=26$

The value of b is 26.

So, the given function is

$f(x)=x^2+26x+182$

Now, add and subtract square of half of coefficient of x.

$f(x)=x^2+26x+182+(13)^2-(13)^2$

$f(x)=(x^2+2(13)x+(13)^2)+182-169$

$f(x)=(x+13)^2+13$

On comparing with $f(x)=(x-h)^2+k$ , we get

$h=-13$

$k=13$

Therefore, your answer is incorrect.

It costs you $10 to draw a sample size n=1 and measure the attribute of interest. you have a budget of $1,200

kicyunya [14]

<span>a. </span>Do you have sufficient funds to estimate the population mean for the attribute of interest with a 95% confidence interval 4 units width? Assume that sd= 12

n= {[(Zalpha/2)^2]*[sd]^2}/ se^2

n= (1.96)^2*(12)^2/ (2)^2

n= 138.297 rounded up to 139

<span>There is not enough funds for this one since you’ll need 139 pieces and it costs 10 a piece, you’ll need 1390.</span>

b. 90% confidence interval

n= {[(Zalpha/2)^2]*[sd]^2}/ se^2

n= (1.645)^2*(12)^2/ (2)^2

n=98

There is enough funds since 98 pieces for 10 a piece is equal to 980.

How to round 831,756 nears hundred thousand

Anettt [7]

Answer:

800,000

Step-by-step explanation:

If the number was above 850,000 it would round up. If the number was 849,999 or below it would round down. In other words, you look at the number to the right of the hundred thousands place, or the number in the tens of thousands place, and if it is 5 or above you round up. 4 and below you round down.

What is −3/8÷7/12 ?

RSB [31]

Answer:

-9/14

Step-by-step explanation:

This is my simplest-

Do the keep-change-flip method for this problem (and also any problem involving this)

KEEP -3/8

CHANGE the division sign to multiplication

FLIP the last fraction. 7/12 to 12/7

Now solve the problem by multiplying the fractions

-3/8 × 12/7 =

-3 × 12 = -36

8 × 7 = 56

-36 / 56 =

Simplify it by dividing the numerator (up of the line) and denominator (below the line) to get -9/14
