W=12 would be the correct answer. I got this because if you divided 12 by 2, (12/2) you would get 6!

w = 12

just multiply 2 by 6 and then you will be left with W equals 12

7. Over the past 50 years, the number of hurricanes that have been reported are as follows: 9 times there were 6 hurricanes, 13

poizon [28]

Answer:

Step-by-step explanation:

Let us first generate the frequency table from the information given:

Hurricane number(X) Frequency(f) f(X)

6 9 54

8 13 104

12 16 192

14 12 168

Total ∑(f) = 50 ∑f(x) =518

In order to determine the last frequency (the remaining years), we will add the other frequencies and subtract the answer from 50, which is the total frequency (50 years). This is done as follows:

Let the last frequency be f

9 + 3 + 16 + f = 50

38 + f = 50

f = 50 - 38 = 12

Now, calculating mean:

$\bar {X} = \frac{\sum f(x)}{\sum(f)} \\\\\bar {X} = \frac{518}{50} \\\\\bar {X} = 10.36$

Therefore mean number of hurricanes = 10.4 (to one decimal place)

3. Give an example of an expression with a rational exponent and explain how to convert it into radical form.

asambeis [7]

<h2>Solution -: </h2>

Example -1 

Here we have ,,, 

$(6 \: x) { \frac{9}{5} }^{}$

solve -; 

6x ^9×1/5

 $\big[(6x \: ) {}^{9} ] {}^{ \frac{1}{5} }$ 

Convert on radical form 

 $\sqrt[5]{(6x) {}^{9} }$ 

Example -2 

 $\displaystyle{}a {}^{ \frac{2}{5} } \\ = \sqrt[5]{x {}^{2} } \: \: \: \: \: \: \: \because ( \sqrt[m]{x {}^{n} } )$ 

<h2>__________________</h2><h3>More Basic Information -: </h3>

hair in the question 3x is called radicant and five is called the index of radical. and in second question X is radicant of the number and five and two are index of the number.

types of Radical -: 

pure radical
mixed radical
unequal radical
equal radical

rationalization 

the operation of multiplication of a radical with the other radical to get product a rational number is called rationalisation.

At her restaurant .Yolanda open 285 cans of tomato sauce .She need to use 4 can of for one pan of lasagna how many pans of lasag

Rudiy27

Answer:

71 1/4 pans of lasagna

Step-by-step explanation:

4 cans of tomato sauce = 1 pan of lasagna

285 cans of tomato sauce = x pan of lasagna

4 = 1

285 = x

Cross product

4*x = 285*1

4x = 285

x = 285/4

x = 71 1/4 pans of lasagna

Find the missing angle.

malfutka [58]

Step-by-step explanation:

Angles in a quadrilateral add to 360 degrees. So, x = 360-88-142-106=24 degrees
