Answer:

Step-by-step explanation:

They are the Same because they have the same slope however they are different because they have different y-intercept and you can do that by the transformation translation

Well, the graph of 1/4x+5 would be shifted 5 units up since the y-intercept would pass through 5. Due to the y- intercept being different, however the slope would still be the same

From a group of 3 men and 4 women, a delegation of 2 is selected. What is the expected number of men in the delegation?

Ostrovityanka [42]

Answer:

The expected number of men in the delegation is 0.86.

Step-by-step explanation:

Number of men = 3

Number of women = 4

A delegation of 2 is selected.

Let X be the number of men selected. So, the possible values of X are 0,1,2.

$P(X=0)=\dfrac{^3C_0\times ^4C_2}{^7C_2}=\dfrac{2}{7}$

$P(X=1)=\dfrac{^3C_1\times ^4C_1}{^7C_2}=\dfrac{4}{7}$

$P(X=2)=\dfrac{^3C_2\times ^4C_0}{^7C_2}=\dfrac{1}{7}$

The expected number of men in the delegation is

$E(x)=0\times P(X=0)+1\times P(X=1)+2\times P(X=2)$

$E(x)=0\times \dfrac{2}{7}+1\times \dfrac{4}{7}+2\times \dfrac{1}{7}$

$E(x)=\dfrac{6}{7}$

$E(x)\approx 0.86$

Therefore, the expected number of men in the delegation is 0.86.

What is BC ? Enter your answer in the box. units

EleoNora [17]

Answer:

Step-by-step explanation:

I'll explain in detail for those of you that want to know.

You know that since angles B and C are congruent to each other that this triangle is an isosceles triangle. Therefore, sides AB and AC are congruent to each other because that is a property of an isosceles triangle.

To solve for x, place the expressions of sides AB and AC equal to each other and solve for the unknown variable.

4x + 1 = 2x + 23

You should get that x = 11.

Substitute x = 11 into the expression for side BC to solve for the length of that side.

f(11) = 3(11) - 8

f(11) = 25

Thus, length of side BC is 25 units.

Use this way of solving for all your future questions. It's really simple :)
