what is the common denominator for 2/5,2/4,2/3?????

The ball will be 864 feet above the ground after 7 seconds. The equation for calculating the height of an object after a certain amount of time given a certain initial velocity is: h = v_0 * t - 0.5 * g * t^2

The equation for calculating the height of an object after a certain amount of time given a certain initial velocity is:

h = v_0 * t - 0.5 * g * t^2

where h is the height, v_0 is the initial velocity, t is the time, and g is the acceleration due to gravity (9.81 m/s^2).

In this case, h = 112 feet/sec * 7 sec - 0.5 * 9.81 m/s^2 * (7 sec)^2

h = 864 feet

The ball will be 864 feet above the ground after 7 seconds.

The product of a number and -7 increased by 9, is at most 16. Find the number.

Answer:

.99

Step-by-step explanation:

345/353 =0.98

cube root =0 .99

so each edge is 0.99 m

The volume of the wood sample is calculated using the given density and mass. Given that this sample is a cube, the volume is also equal to the cube of the edge length. Therefore, finding the cube root of the volume gives us the edge length, which is about 0.99 meters.

The density of a material is defined by the ratio of its mass to its volume, expressed by the formula density = mass/volume. Given that the mass of the sample is 345 kg and the density is 353 kg/m³, you can calculate the volume by rearranging the formula to volume = mass/density. So, the volume comes out to be approximately 0.977 cubic meters. Now, since the sample is a cube, all sides are equal. The volume of a cube is given by the formula volume = edge ^ 3 (edge length cubed). You are hence looking to find the cube root of the volume, which is approximately 0.99 meters. Therefore, the length of one edge of the wood sample is approximately 0.99 meters to the nearest hundredth of a meter.

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 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

A = 6 + 12 + 7 + 7 + 35

A = 67

Case 10

A = 4 · 0.5 · 3² + 9 · 6

A = 18 + 54

A = 72

Case 11

A = 0.5 · 3 · 12 + 3 · 12 + 0.5 · 3 · 12 + 0.5 · 1 · 4 + 0.5 · 5 · 4

A = 18 + 36 + 18 + 2 + 10

A = 84

Case 12

A = 0.5 · 7 · 3 + 7² + 0.5 · 3 · 4 + 0.5 · 3 · 4 + 4²

A = 10.5 + 49 + 6 + 6 + 16

A = 87.5

Case 13

A = 0.5 · 5 · 3 + 0.5 · 1 · 5 + 10 · 8

The probability of the man getting a matched pair of socks when he randomly selects two socks from a drawer is 5/45, or approximately 0.11.

To calculate the probability of the man getting a matched pair of socks when he randomly selects two socks from a drawer, we need to consider the number of possible combinations of socks that result in a match and divide that by the total number of possible combinations of two socks.

The man has a total of 5 pairs of socks, or 10 socks, so there are 10 choose 2, or 45, possible combinations of two socks. Out of these, 5 of them result in a match, because there are 5 pairs of matching socks in the drawer.

Therefore, the probability of getting a matched pair of socks is 5/45, or approximately 0.11. This means that there is an 11% chance that the man will select a matched pair of socks if he randomly selects two socks from the drawer.

a. the probability of finding exactly 6 defects in a carpet roll is approximately 0.0403.

b. the probability of finding 3 or fewer defects in a carpet roll is approximately 0.135.

A) The probability of finding exactly 6 defects in a carpet roll can be calculated using the Poisson probability formula:

P(X = 6) = (e^-λ) * (λ^6) / 6!

where λ = 2.0 (the average number of defects per roll), and e is the mathematical constant approximately equal to 2.71828.

Plugging in the values, we get:

P(X = 6) = (e^-2) * (2^6) / 6! = 0.0403

So the probability of finding exactly 6 defects in a carpet roll is approximately 0.0403.

B) To find the probability of finding 3 or fewer defects in a carpet roll, we need to calculate the cumulative probability:

P(X ≤ 3) = Σ_{i=0}^3 P(X = i) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)

where P(X = i) is the probability of finding exactly i defects, which can be calculated using the Poisson probability formula.

Plugging in the values and adding the probabilities, we get:

P(X ≤ 3) = (e^-2) + (e^-2) * (2^1) / 1! + (e^-2) * (2^2) / 2! + (e^-2) * (2^3) / 3!

P(X ≤ 3) = 0.135

So the probability of finding 3 or fewer defects in a carpet roll is approximately 0.135.

The area of the given figure is 66 square miles.

As we can see in the figure, we have 2 different rectangles attached to one another. So the total area of the figure will be the area of the vertical rectangle plus the area of the horizontal rectangle.

Area of the horizontal rectangle = L₁ × W₁

L₁ = 9 mi

W₁ = 2 mi

∴ Area = 9 mi × 2 mi

= 18 square miles

Area of the vertical rectangle = L₂ × W₂

L₂ = 12 mi

W₂ = 4 mi

∴Area = 12 mi × 4 mi

= 48 square miles

Now, the total area of the figure = the area of the vertical rectangle + the area of the horizontal rectangle.

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.
