6 0

Answer:

11(9 - 2) - 3

Step-by-step explanation:

This is how you write the expression.

Three less means we have a -3.

11 times the sum of 9 - 2 means we have 11(9 - 2)

We put these together to get:

-3 + 11(9 - 2)

Or we can simplify it to:

11(9 - 2) - 3

A class has average height of 68 inches and a standard division of 2 inches what height do you need to be taller than 90% of the
Y_Kistochka [10]

Answer:

65.426

Step-by-step explanation:

Given that:

Mean height (m) = 68 inches

Standard deviation (s) = 2 inches

Height required to be taller than 90% of the class :

P(Z > x) = 0.9

The corresponding Zscore is - 1.282 (Z probability calculator)

Using the Zscore relation :

Zscore = (x - m) / s

-1.282 = (x - 68) / 2

-1.282 * 2 = x - 68

-2.564 = x - 68

-2.564 + 68 = x

x = 65.436

Write the rules for determining the sign of the product when multiplying integers. Then, write the rules for determining the sig
kolbaska11 [484]

An integer is a number that comprises of natural numbers like 0,1,2,3,4... so on and negative whole numbers like -1,-2,-3 and so on.

Multiplication Rules:

1. Product of two positive integers is always POSITIVE.

Eg: 8\ast 6=48

2. Product of two negative integers is always POSITIVE.

Eg: -7\ast -3=21

3. Product of a negative integer and a positive integer is always NEGATIVE.

Eg: 5\ast -4=-20

Quotient Rules:

1. Positive integer divided by a positive integer is always POSITIVE.

Eg: \frac{64}{8}=8

2. Positive integer divided by negative integer or negative integer divided by a positive integer is always NEGATIVE.

Eg: \frac{63}{-3}=-21

3. Negative integer divided by a negative integer is always POSITIVE.

Eg: \frac{-20}{-4}=5

Which values of a, b, and c represent the answer in simplest form?
Hoochie [10]

The value of a is 1 , b = 3 , c = 4 , Option B is the correct answer.

The correct question is

Which values of a, b, and c represent the answer in simplest form?

7/9 divided by 4/9 = \rm a\dfrac{b}{c}

1: a = 1, b = 4, c = 3

2: a = 1, b = 3, c = 4

3: a = 1, b = 63, c = 36

4: a = 1, b = 36, c = 63

<h3>What is reducing to simplest Form ?</h3>

Reducing to simplest form means to reduce to an extent where the numerator and denominator have nothing in common to be cancelled out.

It is given in the question that

(7/9) / (4/9) =  \rm a\dfrac{b}{c}

It can also be written as

(7*9)/(4*9) =  \rm a\dfrac{b}{c}

7/4 = \rm a\dfrac{b}{c}

\rm 1 \dfrac{3}{4} = a\dfrac{b}{c}

Therefore the value of a is 1 , b = 3 , c = 4 , Option B is the correct answer.
