On a multiple-choice test, a student has four possible choices for each question. The student receives 1 point for a correct answer and loses ¼ point for an incorrect answer. If the student has no idea of the correct answer for a particular question and merely guesses, what is the student's expected gain or loss on the question? Suppose you were using an

Answers

Answer:

1 / 16

Step-by-step explanation:

Number of options = 4

Number of correct answers = 1

Number points gained for a correct answer = 1

Number of points lost for an incorrect answer = 1/4 = 0.25

Probability of choosing a correct option = 1/4

Probability of choosing an incorrect option = 3/4

x ____ 1 ______ - 1/4

P(x) __ 1/4 ______ 3/4

Expected gain or loss :

E(x) = Σx*p(x)

E(x) = (1 * 1/4) + (-1/4 * 3/4)

E(x) = 1/4 - 3/16

E(x) = (4 - 3) / 16

E(x) = 1 /16

A gain of 1/16

In a 30° -60° -90° triangle, what is the length of the hypotenuse when the shorter leg is 8 m? Enter your answer in the box.

Answers

Answer:

16

Step-by-step explanation:

In a 30 60 90 degree triangle, the hypotenuse is always double the shorter leg. Hope this helps! :)

The hypotenuse of the 30-60-90 triangle whose shorter leg is 8 m is: 16 m.

What is the 30-60-90 Triangle?

The 30-60-90 triangle is a right triangle whose hypotenuse length is always twice the length of the its shorter leg.

Given a 30-60-90 triangle whose shorter leg is 8 m long, therefore:

Hypotenuse of the 30-60-90 triangle = 2(length of the shorter leg)

Hypotenuse of the 30-60-90 triangle = 2(8)

Hypotenuse of the 30-60-90 triangle = 16 m.

A function f(x) has x-intercepts of -3 and -5. What is the constant term in the function?
f(x) = x2 + 8x +

Answers

Answer:

15

Step-by-step explanation:

The x-intercepts -3 and -5 are also "roots" of the polynomial.  The corresponding factors are (x + 3) and (x + 5).  Multiply the constants together:  3*5 = 15.  This is the desired constant term.

Note that your f(x) = x2 + 8x +   should be written   f(x) = x^2 + 8x +       ...    The " ^ " denotes exponentiation.

Check:  Multiply (x + 3) and (x + 5) together and compare the result to the given polynomial with constant term 15:

f(x) = (x + 3)(x + 5) = x^2 + 3x + 5x + 15 = x^2 + 8x + 15.  This matches!

what is the vertex of f(x)=x^2-9x+14

Answers


Its going to be a lot of steps

Step one

To complete the square, the same value needs to be added to both sides

f(x)+?=x^2 -9x+?+14

Step two

To complete the square add to the expression

x^2 -9 + 81/4= ( x- 9/2 ) ^2 add 81/4
To the expression


f(x)+?=x^2 -9+ 81/4 + 14

Step three

Since 81/4 was added to the right-hand side, also add 81/4 to the left-hand side

f(x)+81/4=x^2 -9x+81/4+14

Step four

Use a^2-2ab +b^2 = ( a-b)^2 to factor the expression

f(x)+81/4=(x-9/2)^2+14

Step five

Move the constant to the right-hand side and change its sign

f(x)=(x-9/2)^2 + 14- 81/4

Last step

Calculate the difference

F(x)=(x-9/2)^2 -25/4

A 25-inch piece of steel is cut into three pieces so that the second piece is twice as long as the first piece, and the third piece is one inch more than five times the length of the first piece. Find the lengths of the pieces.

Answers

Answer:

3 inch    6 inch  16 inch             3+6+16 = 25

Step-by-step explanation:

First piesce = F

Second piece = 2F

third piece = 5F+1

F + (2F) + (5F+1) = 25

8F +1 = 25

subtract 1 om both sides

8F = 24

divide both sides by 8

F= 3

3X2= 6

3X5 +1 = 16

Workers inc just brought 14 boxes of pens to put in their storage. Each box contains 40 pens. If each of the 40 employees takes 2 pens how many will be left in the storage room?

Answers

Answer:

480

Step-by-step explanation:

The computation of the number of pens left in the storage room is shown below:

The total number of pens purchased is

= 14 boxes × 40 pens

= 560

ANd, the total pens take by the employee

= 40 employees × 2 pens

= 80

So, the remaining pens left is

= 540 - 80

= 480

The value of -4 5/8 - x is positive. What are two possible values of x?

Answers

Answer:

-6, -7

Step-by-step explanation:

basically

-4 5/8 - x >0

so

x< -4 5/8

you just need 2 values less than -4 5/8

like -6 and -7

The  possible values of x could be x = -20 or  x = -10 that satisfy the inequality.

Given: -4 5/8 - x > 0

To find two possible values of x that make the expression -4 5/8 - x positive, set up an equation and solve for x.

First, let's convert -4 5/8 to an improper fraction.

The improper fraction equivalent of -4 5/8 is -37/8.

So, -37/8 - x > 0

To isolate x, move -37/8 to the other side of the inequality by adding it to both sides:

x < -37/8

Now, Two possible values of x could be:

x = -20 or  x = -10

Both of these values are less than -37/8, so they satisfy the inequality and make the expression -4 5/8 - x positive.

We have been given that  expressions  as

A 734 ÷ 6

= 367/2

A function assigns the values. The value of (5r+1/5)² when the value of r is 0 equals 0.04.

What is a Function?

A function assigns the value of each element of one set to the other specific element of another set.


Given the function g(r)=(5r+1/5)², therefore, the value of the function when r=0 will be,

g(r) = (5r+1/5)²

g(0) = [5(0)+1/5]²

g(0) = (1/5)²

g(0) = 1/25

g(0)=0.04

Hence, the value of (5r+1/5)² when the value of r is 0 equals 0.04.
