Answer:

The expanded form of 300684 can be written with only 4. Add ends, explain how this is possible for a number with 6 digits. When we look at this number, we want to write that in expanded form, which means we want to write the value of each digit. So i look at the value the 4 in the one's place, so its value is 4 actually 4. The 8 is in the tense place, so its value is 810 point. The 6 is in the hundreds place, so its value is 600 point. The 0 is, in the thousands place, that's 0. Thousands. This 0 is in the 10000 point, so we have 010000 and i'm running out of room. So this 3 is in the 100000. Place of its value is 3 times 100000. It just think of it like money, you have 810 dollar bills, 600 dollar bills, etcetera. So if you have 41 dollar bills, you have 4 dollars. If you have 810 dollar bills, you have 80 dollars: 600 dollar bills. You have 600 dollars now. If you have 0 thousands and 010000, you don't have any money in this, so you don't need to write that down. So now i have 300 dollar bills. Some got a value of 300000 point, so they could leave me only 4 digits that i'm adding together reason being this was 0, so there was no value there.

Hence proved, x*0 = 0.

A statement that is assumed to be true is referred to as a postulate, axiom, or assumption. It is used as the foundation for further deductive reasoning and arguments.

Given many of the typical formulations of the Peano axioms, for example, this is the base case for the definition of multiplication, so it’s an axiom, not a theorem.

x*o = 0

By using an example as rings:

Therefore, By definition of negotiation

= x + (-x)

0 = x · 1 + ( - x) where 1 is the multiplicative identity,

Now,

= x · ( 0 + 1) + ( - x)

Therefore by distributive law,

= x · 0 + x · 1 + (-x)

Where 1 is the multiplicative identity.

By definition of negotiation,

= x · 0  + x + (-x)

= x · 0  + 0

Where 0 is the additive identity.

= x · 0

Therefore, x*0 = 0

John's speed on each section of the walk are 4 km per hour, 0 km per hour and 1.5 km per hour

On the first section, we have the following points

(x, y) = (0, 0) and (1.5, 6)

The speed is calculated as

Speed = (y2 - y1)/(x2 - x1)

This gives

Speed = (6 - 0)/(1.5 - 0)

Evaluate

Speed = 4

On the second section, we have the following points

(x, y) = (1.5, 6) and (2, 6)

The speed is calculated as

Speed = (y2 - y1)/(x2 - x1)

This gives

Speed = (6 - 6)/(2 - 1.5)

Evaluate

Speed = 0

On the third section, we have the following points

(x, y) = (2, 6) and (6, 0)

The speed is calculated as

Speed = (y2 - y1)/(x2 - x1)

This gives

Speed = (0 - 6)/(6 - 2)

Evaluate

Speed = -1.5

Hence, John's speed on each section of the walk are 4 km per hour, 0 km per hour and 1.5 km per hour

The volume of the cylinder is 1809.5 cubic units.

The volume of a cylinder is equal to the product of the area of the circular base and the height of a cylinder. The volume of a cylinder is defined as the space occupied by the cylinder as the volume of any three-dimensional shape is the space occupied by it

V = πr²h

where 'r' is the radius of the base (circle) of the cylinder

'h' is the height of the cylinder

Given that a cylinder with a radius of 6 and height of 16.

Here r = 6 and h = 16,

the volume of a cylinder = πr²h

the volume of a cylinder = π(6)²×16

the volume of a cylinder = 1809.5 cubic units

Thus, the volume of the cylinder is 1809.5 cubic units.

Initially, the graph of g is a three-unit translation, so we have;

Then comes a vertical stretch by such a factor of two and a reflection in the x axis.

The above means that graph must all be multiplied by 2 and that x values containing x are now considered to be -x.

If y and x vary directly, the value of y=2.6 then value of x is 1.14.

The tenths place is represented by the initial digit following the decimal. The hundredths place is denoted by the digit that followed the decimal. Up until there are no additional digits, the remaining ones keep the place values filled in the quantity.

For example, 2.84620364 can be round to two decimal places as 2.85, and 0.8035 can be round to two decimal places as 0.80.

Here x and y vary directly,

So , x/y = k

Therefore K is constant

For x = 3.2 and y = 1.4

Then x/y = k

3.2/1.4 = k

K = 1.6/0.7

If y = 2.6 what is x

y = 2.6 and k = 1.6/0.7

2.6/x = 1.6/0.7

1.6x = 18.2

X = 1.1375.

Hence, the Round to two decimal places of x is 1.14

The dimensions of the rug that Cynthia Besch should buy are 11 ft wide and 25 ft long, which gives an area of 275 ft².

The dimensions of the rug include the width and the length.

Cynthia is budget-constrained to buy 275 ft² only.

When we factorize 275, we have 1, 5, 11, 25, 55, and 275.

The possible combinations of width and length to get 275 ft² and also ensure that a uniform strip of the floor is left around the rug are 11 ft and 25 ft.  This width and length are less than the room's width and length and satisfy the requirement for a uniform strip.

The strip from the room's width and length must be 8 ft each (from all sides).

Width of room = 19 ft

Length of room = 33 ft

Area of room = 627 ft²

Width of rug = 11 ft(19 - 8)

Length of rug = 25 ft (33 - 8)

Area = 275 ft² (11 x 25)

Thus, the dimensions of the rug that Cynthia Besch should buy are 11 ft wide and 25 ft long.

Answer:

10 ≤ x ≤ 19

Step-by-step explanation

The sum of the three lengths is 9 + 12 +x =  21 + x

We know the sum ranges from 31 to 40

So we get the inequality

31 ≤ 21 + x ≤  40

Subtracting 21 from each part of this inequality give

31-21 ≤ x ≤40-21

10 ≤ x ≤ 19

The compound inequality to show the possible lengths of the third side is 10 ≤ x ≤ 19.

A statement of an order relationship-greater than, greater than or equal to, less than, less than or equal to- between two numbers or algebraic equations.

Now it is given as,

Range of sum of three lengths of a fence = 31 to 40 inches

Length of two sides = 9 and 12 inches

Length of third sides = x inches

So, length of sum of three lengths of a fence = 9 + 12 + x

⇒  length of sum of three lengths of a fence = 21 + x

∵ Range of sum of three lengths of a fence = 31 to 40 inches

31 ≤ length of sum of three lengths of a fence ≤ 40

⇒ 31 ≤ 21 + x ≤ 40

Subtracting 21 we get.

10 ≤ x ≤ 19

Thus, the compound inequality to show the possible lengths of the third side is 10 ≤ x ≤ 19.

It often helps to draw a diagram.

(a) X is distributed normally.

(b) The median recovery time is 3 days.

(c) The z score of the patient who takes 4.2 days to recover is 0.75.

(d) The probability of spending more than 2.3 days in recovery is 66.64 %.

(e) The probability of spending between 3.7 and 4.2 days in recovery is 10.7 %.

(f) The 85th percentile for recovery times is 5.24 days.

(a) We are informed that a certain surgical procedure's recuperation time for patients is typically distributed. As a result, X is distributed normally.

(b) The median will be equal to the mean because the patient recovery time has a normally distributed distribution. The median is therefore 3 days.

(c) The formula for z score is given as:

z = X - μ / σ

Now, we have the mean μ = 3 days.

Standard deviation, σ = 1.6 days

The observed value, X = 4.2 days

Therefore,

z = ( 4.2 - 3) / 1.6

z = 1.2 / 1.6

z = 0.75

(d) When X = 2.3 days

Then the z score will be:

z = X - μ / σ

z = 2.3 - 3 / 1.6

z = - 0.7 / 1.6

z = - 0.4375

The corresponding area for z = 0.4375 is 0.3336.

In order to determine the likelihood for a period longer than 2.3 days, we must look at the region to the right, which we can locate by deducting 0.3336 from 1.

Therefore, the probability will be:

p = 1 - 0.3336

p = 0.6664

p = 66.64 %

(e) Now, for the probability between X = 3.7 days and 4.2 days.

z₁ = (3.7 - 3) / 1.6 = 0.7/1.6 = 0.4375

z₂ = (4.2 - 3) / 1.6 = 1.2 / 1.6 = 0.75

The area for a z score of 0.4375 is 0.1664 and the area to left for a z score 0.75 is 0.2734.

Then the probability between 3.7 days and 4.2 days will be:

p = 0.2734 - 0.1664

p = 0.107

p = 10.7 %

(f) For the 85th percentile:

For 0.85 the z score from the table is 1.4.

So, z = 1.4

z = X - μ / σ

1.4 = ( X - 3) / 1.6

(1.4)(1.6) = X - 3

2.24 = X -3

X = 2.24 + 3

X = 5.24 days
