Let sets A and B be defined as follows.
zhenek [66]

Answer:

n(A) = 3

n(B) = 6

-6 ∈ A => True

-14 ∈ A => False

k ∈ B=> True

Q∈B = >False

Step-by-step explanation:

Given

A is the set of integers greater than - 7 and less than - 3

B={c, h, j, k, v, y}

For set A:

The integers greater than -7 will be -6,-5 ....

As the set has integers less than -3, the set will be:

A = \{-6,-5,-4\}

<u>Cardinalities:</u>

Cardinality is the number of elements in the set.

So,

n(A) = 3\\n(B) = 6

Now for the statements:

-6 ∈ A        True as -6 is a member of set A

-14 ∈ A       False as -14 is not a member of A

k ∈ B          True

Q∈B            False

Hence,

n(A) = 3

n(B) = 6

-6 ∈ A => True

-14 ∈ A => False

k ∈ B=> True

Q∈B = >False

Please I need help please hurry I will mark brainliest
katovenus [111]

Step-by-step explanation:

Remember: the formula for solving for volumes:

l • w • h

An easy way to do this is to convert all the numbers to decimals.

3 1/2 = 3.5

5 1/4 = 5.25

4 = 4

Now, we can multiply.

3.5 • 5.25 • 4 = 73.5

Convert 0.5 to a fraction: 1/2

Our final answer: D: 73 \frac{1}{2}

Can someone find slope ?
lana [24]

The slope of the graphed is \frac{8}{5}.

Solution:

Two points represented in the line are (2, 4) and (–3, –4).

Here, x_1=2, y_1=4,x_2=-3,y_2=-4

To find the slope of the line:

$m=\frac{y_2-y_1}{x_2-x_1}

Substitute the given points in the formula.

$m=\frac{-4-4}{-3-2}

$m=\frac{-8}{-5}

$m=\frac{8}{5}

Slope of the line \frac{8}{5}.

Hence the slope of the graphed is \frac{8}{5}.
