What does y 1 2x look like on a graph?

More types of calculations can be performed with data at the nominal level than with data at the interval level.

It is false.

Now, According to the question:

Interval Level of Data Set:

The Interval level of data is a type of data where we have a well-defined ranking and also the difference between Intervals is well defined, however, due to the lack of a proper starting point which is also known as the absolute zero, we cannot find the ratio between two data points. Many examples of the Interval Data set exist such as the temperature scale where we do not have an absolute zero (theoretically the temperature can go infinitely down).

Now, According to the above statement :

More types of calculations can be performed with data at the nominal level than with data at the interval level.

The area of this circle is equal to 363 cm².

In Mathematics and Geometry, the area of a circle can be calculated by using this formula:

Area = πr²

Where:

r represents the radius of a circle.

Note: Radius = diameter/2 = 22/2 = 11 centimeters.

By substituting the radius into the formula for the area of a circle, we have the following;

Area of circle = 3 × 11²

Area of circle = 363 square centimeters.

Given dimensions,

→ Diameter = 22 cm

→ Radius = 22/2 = 11 cm

Now we have to,

→ Find the area of the given circle.

Formula we use,

→ Area of circle = πr²

The given value of π is,

→ π = 3

Then the area of circle will be,

→ A = 363 cm²

Hence, the area is 363 cm².

The number of pounds of trail mix that Anthony bought 4.25 pounds of trail mix.

Trail mix is a snack food that typically contains a combination of dried fruit, nuts, and sometimes chocolate or other sweets. It's a popular snack for hikers and outdoor enthusiasts because it's lightweight, easy to pack, and provides a good source of energy.

The number of trail mix can be realized as 4.25 pounds of trail mix by dividing the total cost of the trail mix ($7.45) by the cost per pound ($1.75).

7.45 / 1.75 = 4.25

You can also think of it as Anthony spent $1.75 for each pound of trail mix and he spent $7.45. So you can find out how many pounds of trail mix he has by dividing the $7.45 by $1.75.

The total number of pupils in the class will be 25.

Solution can be found with a simple calculation.

In the question, it has been given that,

In order to find how many pupils are there in the class ( the total )

Calculate by assuming the unknown quantity as a character

Let total number of pupils be 'p'

So,

No. of pupil that swim = (3/5)p

                                      = 3p/5

No. of pupil that dance = (3/5)p

                                       = 3p/5

5 pupils do both swim and dance.

Since both the counting include these 5 pupils, we will take the 5 away. Thus subtracting the 5

The equation will be,

3p/5 + 3p/5 - 5 = p

6p/5 - 5 = p

6p - 25 = 5p

6p - 5p = 25

p = 25

The Pythagorean theorem states that the sum of the squares of the sides of a right triangle is equal to the square of the hypotenuse.

This means that for a right triangle, the side lengths must satisfy the equation a^2 + b^2 = c^2, where a, b, and c are the three sides.

For example, in option a, the sides 8 cm, 15 cm and 17 cm can form a right triangle. We can calculate the equation to see if it satisfies the Pythagorean theorem: 82 + 152 = 272 and 172 = 289. Since 272 = 289, the equation is true, and the three sides can form a right triangle.

For option b, the sides 3 cm, 3 cm and 9 cm cannot form a right triangle. We can calculate the equation to see if it satisfies the Pythagorean theorem: 32 + 32 = 9 and 92 = 81. Since 9 ≠ 81, the equation is false, and the three sides cannot form a right triangle.

For option c, the sides 2.5 cm, 6.5 cm and 6 cm can form a right triangle. We can calculate the equation to see if it satisfies the Pythagorean theorem: (2.5)2 + (6.5)2 = 36.25 and 62 = 36. Since 36.25 = 36, the equation is true, and the three sides can form a right triangle.

For option d, the sides 16 cm, 30 cm and 34 cm can form a right triangle. We can calculate the equation to see if it satisfies the Pythagorean theorem: 162 + 302 = 576 and 342 = 1156. Since 576 = 1156, the equation is true, and the three sides can form a right triangle.

Answer: Let x be the number of hours the dune buggy is rented for. We know that the cost of the rental is $150 or less, and that the rental is for 2 or more hours.

We know that the cost of the rental is $30 less than the regular price, so we can set up the inequality as follows:

30 + 30x <= 150

Simplifying:

30x <= 120

x <= 120/30

x <= 4

So the solution to the inequality is x <= 4. This means that Tracie can rent the dune buggy for 4 hours or less and spend at most $150, using the coupon.

The graph of the solution will be a line with a slope of 0 and y-intercept at 4, and the solution set is x≤4.

Step-by-step explanation:

The y coordinate of each given point indicates how far it is from the x-axis, thus we may deduce that the distance of the point (-4, 3) from the y-axis is 3 units.

Measuring the distance between two objects or points can sometimes be done statistically and other times qualitatively.

In physics, the term "distance" can refer to a length in the real world or, more usually, to an estimate based on a variety of other criteria.

The distance between any two points on a plane is given by the length of the line segment connecting those points.

The formula d=(((x2 - x1)2 + (y2 - y1)2) is typically used to determine the distance between two locations.

So, we have the points as follows:

(-4, 3)

We can infer that the distance of the point (-4, 3) from the y-axis is 3 because the y coordinate of each given point specifies how distant it is from the x-axis.

Therefore, the y coordinate of each given point indicates how far it is from the x-axis, thus we may deduce that the distance of the point (-4, 3) from the y-axis is 3 units.

The probability that none of the shoes are black is 51.2%.

Probability is a way to gauge how likely something is to happen. According to the probability formula, the likelihood that an event will occur is equal to the proportion of positive outcomes to all outcomes. The probability that an event will occur P(E) is equal to the ratio of favorable outcomes to total outcomes.

Given twenty percent of the shoes in a factory are black,

probability of black shoes = 0.2

probability of not getting a black shoe = 1 - 0.2

probability of not getting a black shoe = 0.8

shoes selected three times and each time the shoe is replaced,

probability for each time is 0.8

for three times = 0.8 x 0.8 x 0.8

total probability = 0.512

probability in percent = 0.512 x 100 = 51.2%

The combined rate of the two pipes is 8/30 of the pool per hour.

To find the time it takes for both pipes to fill the pool together, we can use the formula for finding the combined rate of two processes.

Let's call the rate of the large pipe L and the rate of the small pipe S. We know that L can fill the pool in 6 hours and S can fill the pool in 10 hours, so we can set up the following equations:

L = 1/6

S = 1/10

The combined rate of the two pipes is simply the sum of the individual rates:

L + S = 1/6 + 1/10

We can simplify this expression by finding a common denominator:

L + S = (5/30) + (3/30) = 8/30

So, the combined rate of the two pipes is 8/30 of the pool per hour. To find the time it takes for both pipes to fill the pool together, we can use the formula:

Time = Pool size / Combined rate

Since we do not have the pool size, we cannot determine the exact time it takes. However, we can see that the combined rate is greater than either of the individual rates, so it would take less time for both pipes to fill the pool together than for either one alone.
