Answer: Order from Least to Greatest

-1/8 < 0.33 < 3/8 < 75% < 1 5/8

Step-by-step explanation:

To compare and order fractions we must first convert all integers, mixed numbers (mixed fractions) and fractions into values that we can compare. We do this by first converting all terms into fractions, finding the least common denominator (LCD), then rewriting each term as an equivalent fraction with the LCD. Then we compare the numerators of each fraction and put them in correct order from least to greatest or greatest to least.

The heights of flowering cherry trees are normally distributed with a mean of 11.5 feet, and a standard deviation of 1.7 ft. fin

Fittoniya [83]

Mean (μ) = 11.5 feet

Standard deviation (σ) = 1.7 feet

First we need to find the z-score for less than 13.5 feet.

The formula of z-score is : z = (X - μ)/σ

Here X= 13.5, so z = $\frac{(13.5-11.5)}{1.7}$

z = $\frac{2}{1.7}$ = 1.18

P(X < 13.5) = P(z< 1.18) =P(z< (1.1 + .08)) = 0.8810 (from z-score table)

P(X< 13.5) = 88.1% (for making percentage from decimal, we need to multiply by 100)

So, the probability that a randomly selected tree is less than 13.5 feet tall = 88.1%

A tank contains 3000 L of pure water. Brine that contains 15 g of salt per liter of water is pumped into the tank at a rate of 2

max2010maxim [7]

Answer:

15 g/L

Step-by-step explanation:

Since Brine is added to the tank containing 15g/L at a rate of 25 L/min, the rate at which the quantity of salt in the tank increases is 15 g/L × 25 L/min = 375 g/min. So, in t minutes, the mass of salt in the tank, m is 375 g/min × t min = 375t

Also, the volume of the tank increases by 25 L/min, in t minutes, its volume increases by 25 L/min × t min = 25t. So, the new volume, V is 3000 + 25t.

Since we know, concentration C(t) = m/V = 375t/(3000 + 25t)

dividing through by 25, we have

C(t) = 375t/25/(3000/25 + 25t/25)

C(t) = 15t/(120 + t)

To find the limit as t ⇒ ∞, we divide C(t) by t

C(t) = 15t/t/(120/t + 1)

C(t) = 15/(120/t + 1)

putting t = ∞, we have

C(∞) = 15/(120/∞ + 1)

C(∞) = 15/(0 + 1)

C(∞) = 15/1

C(∞) = 15 g/L

So, as t t → [infinity], the concentration approaches 15 g/L
