Add 5/9+7/9 . Simplify the answer and write a mixed number

Step2247 [10]

Hello there!

First you had to solving by the fractions parts.

$\frac{5}{9}+\frac{7}{9}=\frac{12}{9}$

Then you reducing by the fraction parts of 12/9.

$\frac{12}{9}=\frac{4}{3}$

And finally, you simplify by the fraction parts of 4/3.

$\frac{4}{3}=1 \frac{1}{3}$

Solution by Formulas

Applying the fractions formula for addiction.

$\frac{(5*9)+(7*9)}{9*9}$

$\frac{45+63}{81}$

$=\frac{108}{81}$

Simplifying 108/81 and the answer is

$=1 \frac{1}{3}$

Hope this helps!

Thank you for posting your question at here on Brainly.

I need help with this as well ty lol

Pie

so you use the formula a^2 + b^2 = c^2
so C will be JL
13m^2 + 17m^2 = c^2
458 m = c^2

to leave C alone you need to square root it

√458m = √c^2
21.4 = C

Need help with number 6 and how did you get it

Soloha48 [4]

A rectangular prism is just a shape that looks like a brick.

If you think about a brick for a few seconds, you'll realize
that it has

-- 2 faces of (length by width)
-- 2 faces of (length by height)
and
-- 2 faces of (width by height).

The dimensions of the brick in question 6 are 8ft, 3ft, and 5ft.
So it has

-- 2 faces of 8ft by 3ft
-- 2 faces of 8ft by 5ft
and
-- 2 faces of 3ft by 5ft .

Can you take over and complete it now ?

A courier service company wishes to estimate the proportion of people in various states that will use its services. Suppose the

Svetradugi [14.3K]

Answer:

The probability that the sample proportion will be less than 0.05 is 0.80511.

Step-by-step explanation:

We are given that a courier service company wishes to estimate the proportion of people in various states that will use its services.

Suppose the true proportion is 0.04 and 349 are sampled.

Let $\hat p$ = sample proportion

The z score probability distribution for sample proportion is given by;

Z = $\frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n} } }$ ~ N(0,1)

where, $\hat p$ = sample proportion

n = sample size = 349

p = population proportion = 0.04

Now, the probability that the sample proportion will be less than 0.05 is given by = P( $\hat p$ < 0.05)

P( $\hat p$ < 0.05) = P( $\frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n} } }$ < $\frac{0.05-0.04}{\sqrt{\frac{0.05(1-0.05)}{349} } }$ ) = P(Z < 0.86) = 0.80511

The above probability is calculated by looking at the value of x = 0.86 from the z table which has an area of 0.80511.

Hence, the probability that the sample proportion will be less than 0.05 is 0.80511.
