Answer:

INSPIRING

Step-by-step explanation:

If the sum of the squares of the two shorter sides of a triangle is greater than the square of the longest side, the triangle is acute. However, if the sum of the squares of the two shorter sides of a triangle is smaller than the square of the longest side, the triangle is obtuse. And if the sides satisfy the Pythagorean theorem, it is a right triangle.

If the repeating pattern is “Heart, Star, Star". Then the number of the stars is 12 in Marcia's pattern.

It is also known as the product. If the object n is given to m times then we just simply multiply them.

Marcia is using the rule “Heart, Star, Star to make a repeating pattern. she wants the pattern to repeat 6 times.

Then the number of the stars will be

→ 6 × 2

→ 12

Answer:

Mean: 3 Mad: 1/3

Step-by-step explanation:

First we need to find out the numbers, so to get a mean of 3 we have to get to 9 ebcause there are 3 arrows.

2nd: Once you find the numbers which are 2.5, 3, and 3.5 you add them together and divide it by 3 to get 3 the mean

3rd: Find the MAD but adding .5 and .5 to get 1 then divide it by 3 and you get 1/3 as the MAD.

The archer's mean distance in the second round is 1.6 inches and the MAD is 0.83 inches.

It is the average value of the set given.

It is calculated as:

Mean = Sum of all the values of the set given / Number of values in the set

We have,

Let's first recall that MAD stands for Mean Absolute Deviation, which is a measure of the variability of a set of data.

The MAD is calculated by taking the absolute value of the difference between each data point and the mean, and then finding the average of those absolute values.

Let the mean distance of the archer's arrows in the second round be m, and let the MAD be d.

In the first round, the archer's mean distance was 1.6 inches and the MAD was 1.3 inches.

This means that the absolute difference between each arrow's distance from the mean was, on average, 1.3 inches.

In the second round, the archer's arrows were farther from the center, so we expect the mean distance to be larger than 1.6 inches.

However, the arrows were more consistent, so we expect the MAD to be smaller than 1.3 inches.

To find the new value for the mean distance, we can use the fact that the sum of the distances from the mean is equal to zero. This means that:

3(m - mean) = 0

Solving for m, we get:

m = mean

Therefore, the mean distance in the second round is equal to the mean distance in the first round, which is 1.6 inches.

To find the new value for the MAD, we can use the fact that the variance (the square of the standard deviation) is equal to the average of the squared differences between each data point and the mean.

This means that:

Var = (1/3)(d²)

Since the arrows in the second round are more consistent, we expect the variance to be smaller than in the first round.

Therefore, we can set the new variance to be some fraction f of the old variance, and solve for the new value of d:

f(Var) = (1/3)(d²)

d² = 3f(Var)

d = √(3f(Var))

We don't know the exact value of f, but we do know that it is less than 1 since the variance is decreasing.

Let's assume that f = 0.5 for simplicity.

Using this value of f and the given values for the mean and MAD in the first round, we get:

Var = (1/3)(1.3³) = 0.56

d = sqrt(30.50.56) = 0.83

Therefore,

The archer's mean distance in the second round is 1.6 inches and the MAD is 0.83 inches.

Answer:

Step-by-step explanation:

A

the equation of a quadratic in vertex form is

y = a(x - h)² + k

where (h, k ) are the coordinates of the vertex and a is a multiplier

here (h, k ) = (1, - 4 ) , then

y = a(x - 1)² - 4

to find a substitute the coordinates of any other point on the graph into the equation.

using (0, - 3 )

- 3 = a(0 - 1)² - 4 ( add 4 to both sides )

1 = a(- 1)² = a ⇒ a = 1

y = (x - 1)² - 4 ← in vertex form

B

the equation of a quadratic in standard form is

y = ax² + bx + c ( a ≠ 0 )

using the result from A

y = (x - 1)² - 4 ← expand the factor using FOIL

  = x² - 2x + 1 - 4

y = x² - 2x - 3 ← in standard form

Answer: 6 pounds is the mode

Answer: (x -4)^2 +(y -7)^2 = 36

Step-by-step explanation: The equation of a circle with radius r and center at (h, k) is ...

 (x -h)^2 +(y -k)^2 = r^2

When the diameter is 12, the radius is 6 (half the diameter). Then for your center point, the equation is ...

 (x -4)^2 +(y -7)^2 = 36

The best factoring method that can be considered for the polynomial is (a) perfect-square trinomial

The polynomial is given as:

x² + 12x + 36

The above polynomial has three terms,

This means that the sum or the difference of cubes and squares cannot be applied (because it has more than two terms)

Hence, the best factoring method that can be considered for the polynomial is (a) perfect-square trinomial

Answer:

Step-by-step explanation:

The tangent line must form a right angle with the radius

No, 4 5 6 isn't a right triangle

Answer:

Line m is not a tangent line to circle B.

Step-by-step explanation:

The tangent line to a circle is always perpendicular to the radius.

The line segment measuring 4 units is the radius of Circle B, therefore if line m is a tangent line to the circle, the angle between this segment and the segment measuring 5 units will be a right angle (90°).

We can use Pythagoras' Theorem to check if the triangle is a right triangle.

Pythagoras’ Theorem:  [tex]a^2+b^2=c^2[/tex]

(where a and b are the legs, and c is the hypotenuse, of a right triangle)

Therefore, the legs are the line segments measuring 4 and 5, and the hypotenuse is the line segment measuring 6 units.

Substituting the values for the legs into the formula:

[tex]\implies 4^2+5^2=c^2[/tex]

[tex]\implies 16+25=c^2[/tex]

[tex]\implies 41=c^2[/tex]

[tex]\implies c=\sqrt{41}[/tex]

Therefore, as the hypotenuse of the triangle is not √41, the triangle is not a right triangle, and therefore line m is not a tangent line to circle B.

Using it's concept, it is found that the experimental probability is closest to the theoretical probability​ for number 1.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

The theoretical probability is calculated before any experiments, while the experimental probability is calculated after experiments.

Considering that the sections are equal-sized, the expected frequency for each section is given by:

Ef = 450/8 = 56.25.

The closest frequency to 56.25 is of 58, associated with number 1, which is the one that has the closest probabilities.
