Answer:

All of the above

Step-by-step explanation:

The question is asking you which equation you can use for you to find the value of the undefined variable, n.

In this case, all of the equations above are eligible to find the value of the variable n since regardless of the variable position, you will yet be able to find its value.

Harper has $15.00 to spend at the grocery store. she is going to buy bags of fruit that cost $4.75 each and one box of crackers

Butoxors [25]

She can buy 2 bags of fruit (adds up to 9.50) and of course the box of crackers that is 3.5, in total it adds to $13. So the answer is she can buy 2 bags of fruit.

A game of chance involves spinning a wheel with 4 number on it. The wheel is designed so that the result of each spin Xhas the f

Kipish [7]

Distribution table :

X : ___ 1 _____ 2 _____ 3 ______ 4

P(x) __0.50 __0.25 __ 0.15 ____ 0.10

Answer:

1.85 ; 1.014 ;` 0.55 ; 3.042

Step-by-step explanation:

Probability distribution :

X : ___ 1 _____ 2 _____ 3 ______ 4

P(x) __0.50 __0.25 __ 0.15 ____ 0.10

The mean: E(x) = Σ(X * p(x))

(1*0.5) + (2*0.25) + (3*0.15) + (4 *0.10)

= 1.85

Standard deviation = sqrt(Var(x))

Var(x) = Σ(x²*p(x)) - E(x)²

Var(x) = ((1^2*0.5) + (2^2*0.25) + (3^2*0.15) + (4^2 *0.10)) - 1.85^2

= 4.45 - 3.4225

= 1.0275

Standard deviation = sqrt(1.0275)

Standard deviation = 1.0136567

Standard deviation(X) = 1.014

3.)

Cost of spin = $5

Amount, y to be received = 3 times the number that appears

y = 3x - cost of playing

y = 3x - 5

E(y) = E(3x - 5)

E(y) = E(3x) - 5

Recall :E(x) = 1.85

E(y) = 3(1.85) - 5

E(y) = 0.55

Standard deviation :Sd(y) =

Sd(3x - 5)

3(1.014)

= 3.042

two complementary angles have a difference of 36°. Find the measure of each angle. (Complementary angles are angles that add up

ElenaW [278]

Answer:

27°,63°

Step-by-step explanation:

Let the two angles be a and b.

They are complementary, meaning they add up to 90. Thus:

$a+b=90$

And we are told their difference is 36. Therefore:

$a-b=36$

Solve for the system of equations. Add b to both sides in the second equation:

$a=b+36$

Substitute this into the first:

$(b+36)+b=90$

Combine like terms;

$2b+36=90$

Subtract 36:

$2b=54$

Divide by 2:

$b=27$

So, b is 27 degrees.

Use the second equation again:

$a-b=36$

Now that we know b is 27, substitute:

$a-27=36$

Add 27 to both sides:

$a=63$

So, a is 63 degrees.

And we're done :)

Please help!posted picture of question

DerKrebs [107]

The question states the the graph is non-vertical. This mean the graph is either rise of falling. This also means that the value of function is not same at more than one value of x.

Another hint the question gives us is that the graph is a straight line. So this means we have a straight line rising or falling with some angle or a slope. This signifies a linear function.

It would have been a non-function if the line was a vertical one.
It would have been a non-linear function if the line was not straight.
The graph of exponential function is not straight.

Hence the answer to this question is Linear Function
