Answer:

<h3>7</h3>

Step-by-step explanation:

Mean number = Sum of all the numbers/ Total number of old boys

Given the data

2, 4, 6, 12, 8, 10

Sum = 2+4+6+12+8+10

Sum = 42

Total number of old boys = 6

Substitute into the formula

Mean number of aggressive acts = 42/6

Mean number of aggressive acts = 7

<em>Hence the mean number of aggressive acts for this group of children is 7</em>

Answer:

{5, 6, 7}

Step-by-step explanation:

When we have a given relation, the domain is the set of inputs, and the range as the set of the outputs.

so for a function f(x), and a domain {a. b. c}

The range is:

{f(a), f(b), f(c)}

In this case, we have:

f(x) = x + 6

and the domain is {-1, 0, 1}

Then the range is:

{ f(-1), f(0), f(1) }

{-1 + 6, 0 + 6, 1 + 6}

{5, 6, 7}

The correct option is the third one.

scoray [572]
<span>length = 7x
</span><span>width = 2x

2(7x + 2x) = 72
7x + 2x = 72/2
9x = 36
x = 36/9
x = 4
</span>
width = 2x = 2 * 4 = 8 units<span>

Claire walked her dog 2 1/5 miles. Carson walked her dog 1 3/4 times as far as Claire did. How many more miles did Carson walk h
Anon25 [30]

The word "times" means you have to multiply.

2 1/5 times 1 3/4 is 3 17/20.

The phrase "how many more" means you have to subtract.

3 17/20 minus 2 1/5 is 1 13/20.

Carson walked her dog 1 13/20 more miles than Claire did.

Sorry for the lazy explanations Imao
