Answer:

24x / 5y

Step-by-step explanation:

Given :

24x² / 5xy

24x² = 24 * x * x

5xy = 5 * x * y

Hence,

24x² / 5xy = (24 * x * x) / (5 * x * y)

= (24 * x) / (5 * y)

= 24x / 5y

Answer:

$\bar x = 356.73$ ---Atlanta

$\bar x = 400.95$ --- Salt Lake City

Step-by-step explanation:

Given

The round trip flight data of Atlanta and Salt Lake City

Required

The mean price of both

Mean is calculated as:

$\bar x = \frac{\sum x}{n}$

For Atlanta

$\bar x = \frac{291.6 + 321.6 + 340.1 + 339.6 + 359.6 + 384.6 + 309.6 + 415.6 + 293.6 + 249.6 + 539.6 + 455.6 + 359.6 +333.9}{14}$

$\bar x = \frac{4994.2}{14}$

$\bar x = 356.73$

For Salt Lake City

$\bar x = \frac{570.1 + 354.6 + 465.6 + 219.6 + 311.6 + 297.6 + 471.6 + 618.4 + 513.6 + 523.2 + 381.6 + 159.6 + 267.6 + 458.6}{14}$

$\bar x = \frac{5613.3}{14}$

$\bar x = 400.95$

45%, 15%, 40%, 80%, 65%, 30%, 90%, 25% Do any of these percentages match the fraction 2/5?

Slav-nsk [51]

Answer:

Yes, the third option (40%)

Step-by-step explanation:

Given the fraction with numerator 2 and denominator 5:

$\frac{2}{5}$

You can convert it from this fraction form to a decimal number by dividing the numerator 2 by the denominator 5, obtaining the decimal number:

$\frac{2}{5}=0.4$

Finally, to rewrite this decimal number to percentage, you need to multiply it by 100. Then:

$0.4*100=40\%$

Therefore, there is a percentage that matches the fraction $\frac{2}{5}$ . This percentage is 40%, which corresponds to the third option.

A survey was taken of twenty dentists about Sparkly toothpaste. Sixteen of the dentists recommended Sparkly toothpaste to their

Bas_tet [7]

Answer: There are 40 dentists who would recommended Sparkly toothpaste to their patients .

Step-by-step explanation:

Since we have given that

Out of 20 dentists, a survey was taken of about Sparkly toothpaste,

Number of dentists recommended Sparkly toothpaste to their patients = 16

Percentage of dentists who recommended Sparkly toothpaste to their patients be

$\frac{16}{20}\times 100=80\%$

Out of 30 dentists, a survey was taken of about Sparkly toothpaste,

Number of dentists recommended Sparkly toothpaste to their patients = 24

Similarly,

Percentage of dentists who recommended Sparkly toothpaste to their patients be

$\frac{24}{30}\times 100=80\%$

Now, we have asked to find the number of dentists recommended Sparkly toothpaste to their patients if survey was taken of 50 dentists.

As we have seen that there is always 80% of total number of dentists surveyed have recommended Sparkly toothpaste to their patients ,

so, According to this pattern , we get that

$\frac{80}{100}\times 50=40$

Hence, there are 40 dentists who would recommended Sparkly toothpaste to their patients .
