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
What is the value of x in the figure?
Answer:

Step-by-step explanation:
what is the general rule of the following geometric sequence
-4; -1; -1/4
Answer:
Each of these numbers is divided by four to get the next number in the sequence, so the rule of this would be divide by 4.
Step-by-step explanation:
-4/4 is -1, -1/4 is -1/4 (negative one-fourth), and so on.
In the last 150 years, the average height of people in the industrialized nations has increased by 1/3 foot. Today, American men have an average height of 5 7/12 feet. What was the average height of American men 150 years ago? show your work
Answer:
5 1/4 feetStep-by-step explanation:
Average height now:
5 7/12 feetThe difference:
1/3 footAverage height 150 years ago:
5 7/12 - 1/3 = 5 + 7/12 - 4/12 =5 + 3/12 =5 + 1/4 =5 1/4 feetThe sum of Paul’s and Sam’s ages is 4 and the difference between their ages is 0. Two equations to model this situation are x + y = 4 and x - y = 0. The solution represents both of their ages. What quadrant does the solution lie in?
A.) IV
B.) II
C.) III
D.) I
Answer:
D.) |.
Step-by-step explanation:
x + y = 4
x - y = 0 Adding:
2x + y - y = 4
2x = 4
x = 2
and y = 4 - 2 = 2.
The point (2, 2) is in quadrant |

It is an odd question though.
Solve for x
4/x = 2/7
Use a Pythagorean Triple to find x.
Answer:
x = 51
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
x² = 45² + 24² = 2025 + 576 = 2601 ( take the square root of both sides )
x = [tex]\sqrt{2601}[/tex] = 51
Answer:
x = 51.
Step-by-step explanation:
The triple you require is 17-15-8
We have x-45-24
- that is three times each number in the triple.
So x = 3*17 = 51.

What is the length of the hypotenuse?
Answer:
Hypotenuse is 91 km
Step-by-step explanation:
a² + b² = c²
35² + 84² = c²
1225 + 7056 = c²
c² = 8281
[tex]\sqrt{c^2} =\sqrt{8281}[/tex]
c = 91

Hi! Please help out if you can to explain it! I need so much help on this !
Step-by-step explanation:
When you translate something, it means to move it exactly as it is from once location to another. In this case, move the object 3 units right, and 3 units up. Each line segment is 1 unit. To translate this object, move each point 3 unit up and 3 units right. After that, connect the points to draw the object.

The regular price of a pair of Rothy's (water bottle shoes) is $145. They are on sale for 38% off. What is the sale price?
Answer:
$89.90
Step-by-step explanation:
38% corresponds to the decimal fraction 0.38.
The amount of the discount is 0.38($145), or $55.10. Subtracting this amount from the regular price yields $145 - $55.10 = $89.90.
A faster way of doing this problem is to subtract 0.38 from 1.00, obtaining 0.62, and then multiplying $145 by this 0.62: $89.90.

A line with a slope of -2 is written in the form y=mx+b.
what is the value of b If the line passes through the point (5,-7)?
Answer:
b = 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
Here m = - 2 , then
y = - 2x + b ← is the partial equation
To find b substitute (5, - 7 ) into the partial equation
- 7 = - 10 + b ⇒ b = - 7 + 10 = 3

Write an equation for the line parallel to the given line that contains C.
C(1,4); y=−3x+1
Answer:The equation of a line is y = mx + b where y = y-coordinate, m = slope, x = x-coordinate, and b = y-intercept. (Remember that the slope is the steepness of a line and the y-intercept is the point where the line intersects the y-axis. The x- and y-coordinates are values of the points on the line of y = 3x - 1.)
