Of the labeled points, which represents the animal
Paha777 [63]

The ratio of life expectancy to gestation period is greatest at point (A) A.

<h3>What is life expectancy?</h3>
  • Life expectancy is a statistical measure of how long an organism is expected to live based on its birth year, current age, and other demographic factors such as gender.
  • The most commonly used metric is life expectancy at birth (LEB), which has two definitions.

To find the labeled points, which represent the animal for which the ratio of life expectancy to gestation period is greatest:

  • The graph below shows life expectancy on the y-axis and gestation period on the x-axis.
  • The life expectancy to gestation period ratio for point A is 7/22.5 = 14/45.
  • For point B, the ratio is 8/45.
  • Because the y coordinate is greater at Y than at X, which has the same x coordinate, we only consider the ratio at D, which is 10/51.
  • Since 14/45 > 8/45, we only have to compare 14/45 and 10/51.
  • So, 14 × 51 = 714 and 45 × 10 = 450.
  • Then, 14/45 > 10/51.

Therefore, the ratio of life expectancy to gestation period is greatest at point (A) A.

Oe paid \$18.60$18.60dollar sign, 18, point, 60 in sales tax and tips for her dinner. The sales tax rate is 11\%11%11, percent,
snow_tiger [21]

Answer: The price of Zoe's dinner before sales tax and tips is $13.96.

Step-by-step explanation:

Since we have given that

Amount Zoe paid after sales tax and tip = $18.60

Let the price before tax be 'x'.

Rate of sales tax = 11%

So, it becomes,

\frac{11}{100}\times x\\\\=0.11x

So, Amount after tax, our equation, becomes,

x+0.11x=\$18.60\\\\1.11x=\$18.60\\\\x=\frac{18.60}{1.11}\\\\x=\$16.75

Now, let the amount before tips be 'y'.

Rate of tips = 20%

So, it becomes,

\frac{20}{100}\times y\\\\=0.2y

So, After tips it becomes,

y+0.2y=\$16.75\\\\1.2y=\$16.75\\\\y=\frac{16.75}{1.2}\\\\y=\$13.96

Hence, The price of Zoe's dinner before sales tax and tips is $13.96.
