E ∩ F = {}

Step-by-step explanation:

Intersection is an operation performed on sets. In intersection, the common elements of the sets involved are written,

Given

E = {1, 2, 3}

F = {101, 102, 103, 104}

We have to find the intersection of both sets as indicated

So,

E ∩F =  {1, 2, 3} ∩ {101, 102, 103, 104}

E ∩ F = {}

As there are no common elements in both sets the intersection will be an empty set

Filipe was playing with a triangle on a coordinate plane. The triangle's area is 24 square units. The largest circle he can fit
pickupchik [31]

Answer:

52.36%

Step-by-step explanation:

First, you need to find the radius of the circle. You can do this by using the Pythagorean theorem, which states a^2+b^2=c^2. In this case, a and b are equal to 1.2 and 1.6, and c is the radius of the circle. Plugging in we get 1.2^2+1.6^2=c^2 or 1.44+2.56=c^2 or 4=c^2. Finding the square root of both sides of the equation, we find that 2=c. Now that we have the radius, we can find the area of the circle. The area of a circle is expressed as πr^2, and plugging in 2 for r we get an area of 4π, or ~12.56637. Now all we do is divide 12,56637 by 24 and get what percentage of the area of the triangle the circle covers, which is roughly 0.5236, or 52.36%

The standard deviation tells us a. the average value of the scores. b. the relative standing of a particular score. c. the skewn
andreyandreev [35.5K]

We can say that the standard deviation tells us <u>the </u><u>dispersion </u><u>of the scores</u>, making <u>option D</u> the correct choice.

<h3>What is the standard deviation?</h3>

A standard deviation (or σ) is a measure of how widely distributed the data is about the mean (μ). A low standard deviation suggests that data is grouped around the mean, whereas a large standard deviation shows that data is more spread out. A standard deviation around 0 suggests that data points are close to the mean, whereas a high or low standard deviation indicates that data points are above or below the mean, respectively.

We use the following formula to compute the standard deviation:

\sigma = \sqrt\frac{{\sum_{i=1}^{N}\left | x_i - \mu \right | }^2}{N}

In this formula, σ is the standard deviation, x_i is the data point in the set we are solving for, μ is the mean, and N is the total number of data points.

<h3>How to solve the question?</h3>

In the question, we are asked to tell what standard deviations tell us from the given options.

From the above discussion, we can say that the standard deviation <u>tells us the </u><u>dispersion </u><u>of the scores</u>, making <u>option D</u> the correct choice.

BRAINLEST?! ☺️ What are the features of the quadratic function graphed in the figure?
n200080 [17]

Answer:

C

Step-by-step explanation:

The minimum point is (3, -4). Therefore, vertex = (3, -4).

The curve intersects the x-axis at (1,0) and (5,0). Therefore, the x-intercepts are (1,0) and (5,0).

The curve intersects the y-axis at (0,5). Therefore, the y-intercept is (0,5).

As the curve changes from decreasing to increasing at x = 3, there is an axis of symmetry at x = 3.
