iogann1982 [59]

Answer:

The answer to your question is: 6 ft

Step-by-step explanation:

Data

height = ?

Volume = 509 ft³

radius = 9 ft

π = 3.14

Formula

V = (1/3) πr²h

Process

h = 3V / πr²

h = 3(509) / (3.14x9²) substitution

h = 1527 / 254.34 simplification

h = 6. ft

Dvinal [7]

Answer:

The probability that a student is proficient in mathematics, but not in reading is, 0.10.

The probability that a student is proficient in reading, but not in mathematics is, 0.17

Step-by-step explanation:

Let's define the events:

L: The student is proficient in reading

M: The student is proficient in math

The probabilities are given by:

$P (L) = 0.81\\P (M) = 0.74\\P (L\bigcap M) = 0.64$

$P (M\bigcap L^c) = P (M) - P (M\bigcap L) = 0.74 - 0.64 = 0.1\\P (M^c\bigcap L) = P (L) - P (M\bigcap L) = 0.81 - 0.64 = 0.17$

The probability that a student is proficient in mathematics, but not in reading is, 0.10.

The probability that a student is proficient in reading, but not in mathematics is, 0.17

How just how..........

vredina [299]

Step One

Change to improper fractions.

1 3/11 = 14/11

1 3/4 = 7/4

Step Two

Find the common denominator

11 = 11 * 1

4 = 2 * 2

The common denominator = 11 * 2 * 2 = 44

Step 3

change the improper fractions to the common denominator.

$\dfrac{14}{11} = \dfrac{14 * 4}{11 * 4} = \dfrac{56}{44}$

$\dfrac{7}{4} = \dfrac{7 * 11}{11 * 4} = \dfrac{77}{44}$

$\dfrac{56}{44}-\dfrac{77}{44} = \dfrac{-21}{44}$

-21/44 That has to be your final answer.
