Answer:

$g(x) = 6$

Step-by-step explanation:

Begin with substuting the x variable with -2, we do this because the question has listed the value of x already.

Using the value of x, -2 we determine g(x).

g(x) = -2^2 + 2

Above is what the equation would look as, after you input the value of -2.

Using pemdas, (parantheses, exponents, multiplication, division, addition, subtraction) solve the equation.

-2^2 = 4

Think of it as -2 * -2, which is why -2^2 is 4.

Add 4 +2.

4 + 2 = 6.

Therefore, the value of g(x) = 6

Can u please help me solve? I'm reviewing for finals.

Given:

Consider the given graph as a reference of the solution.

To find:

$-3(u\cdot v)$

Explanation:

By analyzing the graph, we can define the coordinate of vector u and v:

$\begin{align} & \vec{u}=(-8,-9)-(0,0)=(-8,-9) \\ & \vec{v}=(3,7)-(0,0)=(3,7)\end{align}$

Now, let perform the dot product of two vectors,

$\begin{gathered} u\cdot v=(-8,-9)\cdot(3,7) \\ u\cdot v=(-8)(3)+(-9)(7) \\ u\cdot v=-24-63 \\ u\cdot v=-87 \end{gathered}$

Now, perform the required operation,

$\begin{gathered} -3(u\cdot v) \\ =-3(-87) \\ =261 \end{gathered}$

Final answer:

Hence, the required solution is:

$-3(u\cdot v)=261$

Answer:

Their expenses and sales will both equal at 200 ounces.

Step-by-step explanation:

This can be determined using the break-even point in ounce formula as follows:

Break even point in ounce = Fixed cost / Contribution per ounce

Where;

Fixed cost = Advertising = $600

Contribution per ounce = Selling price per ounce - Cost per ounce = $4 - $1 = $3

Substituting the values into equation (1), we have:

Break even point in ounce = $600 / $3 = 200 ounces

Therefore, their expenses and sales will both equal at 200 ounces.

Assume the blood type distribution to be A: 41 %, B:9 % , AB: 4%, O: 46 % . What is the probability that the blood of randomly s

Sergio039 [100]

Answer: a) 50% , and b) 50%.

Step-by-step explanation:

Since we have given that

P(A) = 41%

P(B) = 9%

P(AB) = 4%

P(O) = 46%

Since antigen A or antigen B are independent events.

So, P(A ∪ B) = P(A) + P(B)

$P(A\cup B) = 41\%+9\%=50\%$

Probability neither the A nor the B is given by

$P(A'\cap B')=P(A\cup B)'=1-0.50=0.50=50\%$

Hence, a) 50% , and b) 50%.
