I I need help with this I’ll mark you if your right
AveGali [126]

Answer:

C

Step-by-step explanation:

The distance around the circle is asking for the circumference of the circle.

Since we know that the diameter is 21 and the equation for the circumference of a circle is 2*pi*r and since 2*r is just the diameter, we can say that the circumference is 21*pi, which would be C.

<h2>Intersection and Union of Sets</h2><h3>Answer:</h3>

A \cup B = \{ a, b, c, d, e \}

B \cap C = \{ d, e \}

A \cup C = \{ a, b, c, d, e, f \}

<h3>Step-by-step explanation:</h3>

Given:

A = \{ a, b, c, d \}

B = \{ b, d, e \}

C = \{ d, e, f \}

The Union (\cup) of sets A and B is just a set containing all the elements of sets A and B. However, elements that are present in both sets should not repeat in the Union of Sets as the elements of a set should distinct be from each other.

Part i:

A \cup B \\ \{ a, b, c, d \} \cup \{ b, d, e \} \\ \{ a, b, c, d, e \}

The Intersection (\cap) of sets A and B is just a set containing all the elements that are both present in sets A and B.

Part ii:

B \cap C \\ \{ b, d, e \} \cap \{ d, e, f \} \\ \{ d, e \}

Part iii:

A \cup C \\ \{ a, b, c, d, \} \cup \{d, e, f \} \\ \{ a, b, c, d, e, f \}

Anna007 [38]

Answer:

You can find the mean, by adding all the terms in each data set and dividing by the number of terms.  For example, if there were four data points, you would add them all up and divide by four.
