Answer:

30/100

Step-by-step explanation:

25%= 25/100

50%= 50/100

3/100 is in the middle of the two fractions. So one of the possible answer can be 30/100 or 30%

Answer:

[tex]\sf \dfrac{2}{5}[/tex]

Step-by-step explanation:

"per cent" means "per hundred".  Therefore, to change a percent to a fraction, remove the % sign and place the number as the numerator of a fraction with 100 as the denominator.

[tex]\sf 25\%=\dfrac{25}{100}[/tex]

[tex]\sf 50\%=\dfrac{50}{100}[/tex]

Any percent between 25% and 50% can be written as a fraction in the same way.  

Choose a number between 25 and 50, place it as the numerator of a fraction with 100 as the denominator:

[tex]\sf \dfrac{40}{100}[/tex]

Now reduce the fraction to its simplest term by dividing the numerator and denominator by the greatest common factor (GCF):

[tex]\sf \dfrac{40 \div 20}{100\div 20}=\dfrac{2}{5}[/tex]

Therefore, the fraction ²/₅ is between 25% and 50% as it is equivalent to 40%.

The degree of effect refers to the extent to which any differences in the outcome variables are related to the experimental treatment. It can be quantified using various statistical measures and is an important consideration in experimental design and analysis. However, it is not the only factor to consider, and other factors such as the magnitude of effect and potential confounding variables should also be taken into account.

In experimental design and analysis, the degree to which any differences in the outcome variables are related to the experimental treatment is an important consideration. This is typically referred to as the "degree of effect" or "degree of difference."

The degree of effect refers to the extent to which the experimental treatment produces differences in the outcome variables being measured. This can be quantified using various statistical techniques, such as the analysis of variance (ANOVA) or regression analysis, which compare the variation in the outcome variable between groups or over time. It is typically expressed as a statistical measure, such as a p-value or a confidence interval, which indicates the level of confidence that can be placed in the observed differences. A low p-value or a narrow confidence interval indicates a high degree of effect, indicating that any observed differences are likely to be related to the experimental treatment rather than chance or other factors.

In addition to the degree of effect, it is also important to consider the magnitude or size of the effect. This refers to the extent or strength of the differences between the treatment groups, and can be expressed using various effect size measures, such as Cohen's d or eta-squared. A larger effect size indicates a stronger or more meaningful difference between the groups, and is generally considered to be more important than a smaller effect size.

However, it is important to note that the degree of effect and magnitude of effect are not the only factors to consider when evaluating the results of an experiment. Other factors, such as the study design, sample size, and potential confounding variables, can also affect the interpretation of the results and the conclusions that can be drawn.

Answer:

f(x) = x + 5

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 5, 0) and (x₂, y₂ ) = (0, 5) ← 2 points on the line

m = [tex]\frac{5-0}{0-(-5)}[/tex] = [tex]\frac{5}{0+5}[/tex] = [tex]\frac{5}{5}[/tex] = 1

the line crosses the y- axis at (0, 5 ) ⇒ c = 5

y = x + 5 , or

f(x) = x + 5

Answer:

x+5

Step-by-step explanation:

Because I said so

The equation of line is y = -10x + 1500 , where the slope is m = -10

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Substituting the values in the equation , we get

y = -10x + 1500   be equation (1)

where x is the number of minutes

and y is the altitude in feet

when x = 0

Substituting the value of x = 0 in the equation , we get

y = 1500 feet

when x = 5

Substituting the value of x = 5 in the equation , we get

y = -10 ( 5 ) + 1500

y = -50 + 1500

y = 1450 feet

when x = 8

Substituting the value of x = 8 in the equation , we get

y = -10 ( 8 ) + 1500

y = -80 + 1500

y = 1420 feet

when x = 10

Substituting the value of x = 10 in the equation , we get

y = -10 ( 10 ) + 1500

y = -100 + 1500

y = 1400 feet

when x = 30

Substituting the value of x = 30 in the equation , we get

y = -10 ( 30 ) + 1500

y = 300 + 1500

y = 1200 feet

So , the plane's altitude after 5 minutes would be 1450 feet and after 30 minutes, the plane's altitude would be 1200 feet

Now , the plane will reach the ground when y = 0

0 = -10x + 1500

10x = 1500

x = 150 minutes

Hence , the equation of line is y = -10x + 1500

Step-by-step explanation:

The two amount of numbers are 11 and 135. 11 is a multiple of 11 and 135 is a multiple of 17. The sum of the two numbers is 146.

Step 1: One of the numbers is a multiple of 11

Let the number be 11x, where x is an integer

Step 2: The total of the two numbers is 146

Therefore, 11x + 17y = 146, where y is an integer

Step 3: Solve the equation

11x + 17y = 146

11x = 146 - 17y

x = (146 - 17y) / 11

Step 4: Find the two numbers

x = (146 - 17y) / 11

For y = 1, x = 11

Therefore, the two numbers are 11 and 17.

The two numbers that add up to 146 are 11 and 135. 11 is a multiple of 11, which means it is divisible by 11 without any remainder. 135 is a multiple of 17, which means it is divisible by 17 without any remainder. When these two numbers are added together, the sum is 146. This means that 11 and 135 are the two numbers that add up to 146. 11 is a multiple of 11 and 135 is a multiple of 17, which explains why the sum of the two numbers is 146. The two numbers together can be used to represent a variety of different mathematical equations, such as the addition of two integers or the multiplication of two fractions. Knowing the two numbers that add up to 146 can be useful in a variety of different scenarios, such as solving math problems or accounting for the total of two items.

The rule is to add the exponents when multiplying exponential expressions. The bases must be the same. The rule in symbolic form is a^b*a^c = a^(b+c)

For f(1) = 0 the statement is true that (x - 1) is the factor of the function.

Polynomial is formed composed of the phrases Nominal, which means "terms," and Poly, which means "many." An expression that consists of variables, constants, and exponents that are combined using mathematical operations like addition, subtraction, multiplication, and division is referred to as a polynomial.

Given a function,

f(x) = x⁶ - x⁴ + 2x² - 2

and f(1) = 0

substitute the values,

f(x) = x⁶ - x⁴ + 2x² - 2

f(1) = 1⁶ - 1⁴ + 2(1)² - 2

f(1) = 0

After 15 years, the area of the forest will be approximately 1523.4 km

A percentage is a unit used to express a portion of a whole number as a fraction of 100.

In this scenario, we are know that the area of a forest decreases by 6.25% each year. This means that each year, the area of the forest will decrease by

=> 6.25/100 times its original size.

To find the area of the forest after 15 years, we need to calculate the total decrease in area over 15 years. We can do this by multiplying the original area of the forest by the percentage decrease each year, and then repeating this calculation 15 times.

Starting with the original area of 2500km, we can calculate the first year's decrease by multiplying

=> 2500  x 100/6.25 = 157.5 km.

To find the area after the first year, we subtract

=> 2500 km - 157.5 = 2342.5 km.

We can repeat this calculation for the next 14 years to find the total decrease in area over 15 years. We can also use the calculator provided to simplify the calculation.

To do this, we enter 2500, then press the multiply button, enter 0.0625, then press the equal button, then press the subtract button, and finally enter the result from the previous calculation until we reach the final answer.

A local restaurant charges $15 for a jumbo cheese pizza and $1.35 for each additional topping.

the total cost, y, for x toppings on a jumbo pizza is represented  in slope-intercept form, by the equation y = $1.35x + $15

The slope-intercept equation for the total cost, y, for x toppings on a large cheese pizza is y = mx + b, where m is the slope and b is the y-intercept.

First, we must determine the slope (m). The slope shows the $1.35 cost of each subsequent topping. So, m = $1.35.

The y-intercept must then be determined (b). The y-intercept shows the large cheese pizza's starting cost of $15. So, b = $15.

When we plug these values into the equation, we get:

The work needed to build the pyramid is calculated by multiplying the area of the base by the height and the density of the stone.

The work needed to build the pyramid can be calculated by using the formula Work = Area x Height x Density. The area of the base of the pyramid can be calculated by using the formula Area = Side^2, where Side is the length of the side of the square base. In this case, the side of the square base is 7740 ft. So, the area of the base is 7740^2 ft^2. The height of the pyramid is 860 ft (due to erosion, its current height is slightly less). The density of the stone is estimated at 168 lb/ft. So, the work needed to build the pyramid is calculated by multiplying the area of the base by the height and the density of the stone, like this: Work = 7740^2 ft^2 x 860 ft x 168 lb/ft = 9.76 x 10^9 lb-ft.

The probability of choosing a fisher from Clearwater who had a license is 54/(54+36) = 0.6, and the probability of choosing a fisher from Mountain View who did not have a license is 10/(10+90) = 0.1.

Assuming that the choices are independent, the probability of both events happening together is the product of their probabilities:

P(Clearwater had a license and Mountain View did not have a license) = P(Clearwater had a license) x P(Mountain View did not have a license)

= 0.6 x 0.1

= 0.06

Therefore, the probability that the fisher chosen from Clearwater had a license and the fisher chosen from Mountain View did not have a license is 0.06.

Answer:

The probability that the fisher chosen from Clearwater had a license and the fisher chosen from Mountain View did not have a license is 0.06

Step-by-step explanation:

To solve this problem, we can use the multiplication rule of probability, which states that the probability of two independent events both occurring is equal to the product of their individual probabilities.Let event A be the event that a fisher chosen from Clearwater Park had a license, and let event B be the event that a fisher chosen from Mountain View Park did not have a license. Then, we need to find the probability of A and B occurring together, which we can write as P(A and B).

Using the given information, we can calculate the probabilities of events A and B as follows:

P(A) = 54/(54+36) = 0.6 (the proportion of fishers at Clearwater Park with a license)

P(B) = 10/(90+10) = 0.1 (the proportion of fishers at Mountain View Park without a license)

Since the events are independent (since no one fished at both parks), we can use the multiplication rule to find the probability of A and B occurring together:

P(A and B) = P(A) * P(B) = 0.6 * 0.1 = 0.06
