12 bro it even says to follow the order of operations. If there is only addition and subtraction you just go from left to right. Same with if there is only multiplication and division.

What is the fraction ten twelfths in it's simplest form?

Klio2033 [76]

Hi there!

Below is the fraction we are working with:

$\frac{10}{12}$

To simplify this fraction down to its lowest form, we see what number(s) can go into the numerator and the denominator evenly. We can start off with the number 2. 2 goes evenly into each number, can't it? :)

So, we can cut down $\frac{10}{12}$ to $\frac{5}{6}$ .

$\frac{5}{6}$ is already in it's simplest form. Now, we can see if they're equivalent. If not, we have to start all over.

Since $\frac{10}{12}$ equals 83.3, we have to make sure $\frac{5}{6}$ does, too.

Just divide the numerator by the denominator to see what you have.

5 ÷ 6 = 83.3 with a repeating decimal, so they're equivalent!

Hope this helps!

If you need anything else, don't just sit there - Let me know! :D

V. Money Magazine reported that the average price of gasoline in the United States during the first quarter of 2008 was $3.46. A

Butoxors [25]

Answer:

$z=\frac{3.43 -3.46}{\frac{0.15}{\sqrt{30}}} = -1.095$

$z=\frac{3.49 -3.46}{\frac{0.15}{\sqrt{30}}} = 1.095$

And we can find this probability using the normal standard table and we got:

$P(-1.095$

Step-by-step explanation:

Let X the random variable that represent the price of a population, and for this case we know the distribution for X is given by:

$X \sim N(3.46,0.15)$

Where $\mu=3.46$ and $\sigma=0.15$

And for this case we want to find the following probability:

$P(3.43 \leq \bar X \leq 3.49)$

And we can use the z score formula given by:

$z=\frac{\bar X -\mu}{\frac{\sigma}{\sqrt{n}}}$

If we find the z score for the limits we got:

$z=\frac{3.43 -3.46}{\frac{0.15}{\sqrt{30}}} = -1.095$

$z=\frac{3.49 -3.46}{\frac{0.15}{\sqrt{30}}} = 1.095$

And we can find this probability using the normal standard table and we got:

$P(-1.095$

The sum of three consecutive natural numbers is 1020, find the numbers.

VLD [36.1K]

Answer:

339, 340, 341

Step-by-step explanation:

To find the 3 consecutive numbers, divide the sum by 3 to get the average. 1020/3=340. So the middle number is 340. That means the numbers are 339, 340, and 341.
