In Mathematics and Geometry, a fraction simply refers to a numerical quantity (numeral) which is not expressed as a whole number. This ultimately implies that, a fraction is simply a part of a whole number.

Based on the information provided above, each of the sums can be calculated as follows;

Fraction = 5/6 + 2/9

Fraction = (15 + 4)/18

Fraction = 19/18 = 1 1/18.

Fraction = 1/2 + 2/3

Fraction = (3 + 4)/6

Fraction = 7/6

Fraction = 1/5 + 3/10

Fraction = (2 + 3)/10

Fraction = 1/2

Fraction = 1/4 + 7/10

Fraction = (5 + 14)/20

Fraction = 19/20

Fraction = 3/5 + 1/2

Fraction = (6 + 5)/10

Fraction = 11/10

The given polynomial is

To know if the factor x-1 is a zero of the polynomial, we just have to replace x = 1 in the expression. If we get zero, then z-1 is a solution.

Since x = 1 didn't result in zero, we can deduct that x-1 is not a solution to the given expression.

Equation representing the salary of 2004 in slope intercept form is y = 1000x + 23100, and the salary in 2004 is equal to $27100.

Equation that models the data for the years 2001 and 2003,

Slope and y-intercept of the line that passes through the points (1, 24100) and (3, 26100).

Slope is equal to,

m = (y₂ - y₁) / (x₂ - x₁)

⇒m = (26100 - 24100) / (3 - 1)

⇒m = 2000/2

⇒m = 1000

Y-intercept is equal to ,

b = y - mx

⇒ b = 24100 - 1000(1)

⇒ b = 23100

Equation in slope-intercept form that models the data is written as,

y = 1000x + 23100

To approximate the salary for 2004,

Substitute x = 4 into the equation and get the value of  y,

⇒ y = 1000(4) + 23100

⇒ y = 27100

Therefore, the equation representing the approximate salary in 2004 is y = 1000x + 23100 and the salary for 2004 is approximately $27,100.

Answer:

2y x5

Step-by-step explanation:

To minimize the amount of fencing needed, each of the five pens should have identical dimensions. To minimize the amount of fencing needed, each of the five pens should have dimensions of approximately 13.4 meters by 13.4 meters.

To minimize the amount of fencing for five identical pens adjacent to each other with a total area of 900m², you need to find the dimensions that minimize the perimeter. Let's denote the width of each pen as 'w' and the length as 'l'. Since there are five identical pens, the total width is 5w.
1. Write the area constraint equation:
Total area = 900m²
lw = 900
2. Express 'l' in terms of 'w':
l = 900/w
3. Write the perimeter equation:
Perimeter (P) = 6w + 3l
We use 6w because there are six widths (top and bottom of the pens) and 3l because there are three lengths (the sides of the pens).
4. Substitute 'l' from step 2 into the perimeter equation:
P = 6w + 3(900/w)
5. Differentiate P with respect to w:
dP/dw = 6 - (2700/w²)
6. Set dP/dw to 0 and solve for w:
6 - (2700/w²) = 0
2700/w² = 6
w² = 2700/6
w² = 450
w = √450 ≈ 21.21m
7. Find 'l' using the area constraint equation:
l = 900/w
l = 900/21.21 ≈ 42.43m
So, to minimize the amount of fencing, you should use dimensions of approximately 21.21m for the width (w) and 42.43m for the length (l) for each pen.

Answer:

Wasim has enough money.

Step-by-step explanation:

1. find the area of the garden path:

600 cm x 120 cm = 72,000 sq. cm

2. find the area of each stone:

it is a square of 30 cm by 30 cm, so:

30 cm x 30 cm = 900 sq. cm

3. find how many stones can fit in the path:

72,000 / 900 = 80 stones

4. multiply that by the price of each stone:

80 stones x $2.50 = $200

Wasim's budget is $220 and the stones will only cost $200, so it is within the budget

A student can ride his bicycle at an average speed of 6 mph. If he cycles for 4 hours, how far can he travel 24 miles.

The overall distance the object covers in a given amount of time is its average speed. A scalar value represents the average speed. It has no direction and is indicated by the magnitude.

We can use the formula:

\(Distance = rate * time\)

To solve this problem.

The rate is given as 6 miles per hour, and the time is given as 4 hours.

So, we have:

distance = 6 * 4

Simplifying, we get:

distance = 24 miles

So, the student can travel 24 miles if he cycles for 4 hours at an average speed of 6 mph.

The average rates of change for f(x)=0.1x squared, g(x)=0.3x squared is 0.5 and 1.3 over the interval [1,4].

In order to calculate the average rate of change of a function f(x) over an interval [a,b] we need to implement the formula

A(x) = {f(b) - f(a)] / (b – a)}

Here,

A(x)= average rate of change,

f(a) = value of function,

f(b) = value of function

given, from the question

f(x) = 0.1x^2

g(x) = 0.3x^2

The calculated interval is 1 ≤ x ≤ 4.

Therefore,

for f(x), we have staged the values as

A(x) = {f(4) - f(1)] / (4 - 1)}

= {(0.1 * 4^2) - (0.1 * 1^2)] / (4 - 1)}

= (1.6 - 0.1) / 3

= 0.5

for g(x), we have staged the values as

A(x) = {g(4) - g(1)] / (4 - 1)}

= {(0.3 * 4^2) - (0.3 * 1^2)] / (4 - 1)}

= (4.2 - 0.3) / 3

= 1.3

The average rates of change for f(x)=0. 1x squared, g(x)=0. 3x squared is 0.5 and 1.3 over the interval [1,4].

Step-by-step explanation:

for a confidence interval, decreasing the sample size will have no effect on the width of the confidence interval

Value of Confidence Interval is from 0% to 100% as probability value lies from 0 to 1 for a given set of data values.

Value of Confidence Interval  does not depend upon the Sample Size .It is always from 0% to 100% , whatever the width of sample size is.

Let x represent the worth of the mutual fund last year. We were told that it dropped by 30%

Recall, percentage is expressed in terms of 100. Thus, the amount by which it dropped is

30/100 * x = 0.3x

if the fund is now worth $12,593, it means that

x - 0.3x = 12593

0.7x = 12593

x = 12593/0.7

x = 17990

The worth of the fund last year was $17990

The average time in hours from when a machine breaks until it is fixed is approximately 11.3 hours.

Given,

Benny's arcade has five video game machines

The average time between failures = 34 hours

The maintenance engineer can repair a machine in about = 13 hours

The failure time and repair times are both exponentially distributed

The formula for the mean of an exponential distribution is mean = 1/λ where λ is the rate parameter of the distribution.

In this problem, the rate parameter of both the failure time and repair time is the reciprocal of their respective averages. Therefore,

λ_f = 1/34λ_r = 1/13

Now, let's find the average time from when a machine breaks until it is fixed using the fact that the sum of two independent exponential distributions with rate parameters λ1 and λ2 is itself an exponential distribution with rate parameter λ1+λ2.

So, the rate parameter for the time from when a machine breaks until it is fixed is λ_f+λ_r = 1/34+1/13

= 0.0885 hours⁻¹ (approximately)

Hence, the average time from when a machine breaks until it is fixed is mean = 1/λ= 1/0.0885 ≈ 11.3 hours (approximately).

Therefore, the average time in hours from when a machine breaks until it is fixed is approximately 11.3 hours.

Answer: Two planes intersecting in a line

Explanation:

The wall and floor are two different planes. They meet up to form a line which is the crease between them.

A plane is a flat surface without any bends or curves to it. In theoretical terms, planes go on forever in all directions. Realistically there are limits of course. The wall or floor cannot go on forever.

Another example of two planes would be found in a book. Each page is a plane. Two adjacent pages meet up to form a line (i.e. the spine of the book is a line).

Linear regression is a technique used in statistics and machine learning to understand the relationship between two variables and how one affects the other.

In this case, we are interested in understanding the relationship between sales and seasonality. We can use linear regression to create a model that predicts sales based on seasonality. Here's how we can do it First, let's plot the data to see if there is a relationship between sales and seasonality.

We can see that there is a clear pattern that repeats every year. This indicates that there is a strong relationship between sales and seasonality. We can use the following equation: y = mx + b, where y is the dependent variable (sales), x is the independent variable (seasonality), m is the slope of the line, and b is the intercept of the line.
