During a backgammon game, Jimmy rolled two dice on the board. Find the probability that the sum obtained was greater than 8 given that the number on one die was a 6
Answer:
2/3Step-by-step explanation:
This problem bothers on probability
Given that two dice are expected to give an outcome of sum greater than 8
But in the problem statement the first die is already settled since it is showing 6 already.
Now for the second die, the possible outcomes that will add up with the first die to produce a figure greater than 8 are (3,4,5,6)
The probability of obtaining either of these numbers is 4/6= 2/3
Having the first die settled, this means that the probability of obtaining a sum of 8 is 2/3
On a map, 1cm represents 65 km. If two cities are 1950 km apart, how many centimeters apart would they be on this map?
Answer:
30 cm.
Step-by-step explanation:
We can solve this problem by making a proportion:
1 cm/65 km = x cm/1,950 km
By cross-multiplying, we can solve for x:
65x = 1,950
x = 30

What is the slope of the line that passes through these two points? (-3,4) (5,4)
Answer:
0
Step-by-step explanation:
To find the slope, we use the slope formula
m = (y2-y1)/(x2-x1)
= ( 4-4)/( 5 - -3)
= 0/ ( 5+3)
= 0/8
= 0
Answer two questions about Equations A and B:
A. 5x=20
B. X=4
1) How can we get Equation B from Equation A?
Choose 1 answer:
Multiply/divide both sides by the same non-zero constant
Multiply/divide both sides by the same variable expression
Add/subtract the same quantity to/from both sides
Add/subtract a quantity to/from only one side
Multiply/divide both sides by the same non-zero constant. Therefore, option A is the correct answer.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Given that, A) 5x=20 and B) x=4.
Here, 5x=20
Divide both sides by the same non-zero constant 5, we get
5x/5 =20/5
x=4
Therefore, option A is the correct answer.

Solve for x:
-2 (x -4) - 1/2 (3-4x) = -12
Answer:
No solution for xStep-by-step explanation:
-2 (x -4) - 1/2 (3-4x) = -12
×(-2) ×(-2)
4(x - 4) + (3 - 4x) = 24
4x - 16 + 3 - 4x = 24

Find the width and height of a newer 65" television screen with an aspect
ratio of 16:9.
Answer:
see below
Step-by-step explanation:
65 inches is the diameter of the screen
We have a right triangle for a tv with the side length of 16x and 9x
Using the Pythagorean theorem
a^2 +b^2 = c^2
(16x)^2 + (9x)^2 = 65^2
256x^2+ 81x^2 = 4225
Combine like terms
337x^2 = 4225
Divide each side by 337
x^2 =4225/37
Take the square root of each side
x =65sqrt(337)/337
x =3.54077562
The width is 16 times this
width =56.65240991
height is 9 times this

F(x)=3x-2
Simplify F(2x)-F(x+2)
Answer:
3x - 6
Step-by-step explanation:
To evaluate f(2x) and f(x + 2) substitute x = 2x and x = x + 2 into f(x)
f(2x) = 3(2x) - 2 = 6x - 2
f(x + 2) = 3(x + 2) - 2 = 3x + 6 - 2 = 3x + 4
Thus
f(2x) - f(x + 2)
= 6x - 2 - (3x + 4)
= 6x - 2 - 3x - 4
= 3x - 6

write 3.777777 as a fraction
Answer:
[tex]\huge\boxed{\sf \frac{34}{9}\ \ OR \ \ 3\frac{7}{9} }[/tex]
Step-by-step explanation:
Let
x = 3.777....... (1)
Then
10x = 37.777..... (2)
Subtracting (1) from (2)
10x - x = 37.7777..... - 3.77777.......
9x = 34
Dividing both sides by 9
x = 34 / 9
x = [tex]3 \ \frac{7}{9}[/tex]

The Midpoint of UV is M(4, -6). Find V given U(7, -9)
Answer:
(1, -3)Step-by-step explanation:
Given the Midpoint of UV is M(4, -6) and U(7, -9), we are to find the other coordinate V. The formula for calculating the midpoint of two coordinates is expressed as shown;
M(X,Y) = (x1+x2/2, y1+y2/2)
X = x1+x2/2
Y = y1+y2/2
Given (X,Y) = ()4, -6)
U (x1, y1) = (7, -9)
To get x2 and y2, we will substitute the given values into th formula above;
4 = (7+x2)/2
cross multiply
4*2 = 7+x2
8 = 7+x2
x2 = 8-7
x2 = 1
Similarly for y2;
-6 = (-9+y2)/2
cross multiply
-6*2 = -9+y2
-12 = -9+y2
y2 = -12+9
y2 = -3
Hence the other coordinate V(x2, y2) is (1, -3)

Answer:
Answer: Option B.
Step-by-step explanation:
Hey there!!
Let's simply solve it.
Given,
[tex] \frac{1}{2} x + \frac{1}{4} x = 16[/tex]
Now, take LCM.
[tex] \frac{2x + x}{4} = 16[/tex]
Multiply 16 by 4.
[tex]3x = 16 \times 4[/tex]
or, 3x = 64.
Divide 64 by 3.
[tex]x = \frac{64}{3} [/tex]
x= 21.33
Therefore, your answer is option B.

1. Simplify the expression:
4+36+(10-8)’-3+7
A. 130
B. 100
C. 38
D. 37
Answer:
The answer isn't in the options anyway I'll write it. the answer is 46.
Step-by-step explanation:
According to BODMAS rule - addition should be done first so
4+36= 40 and -3 +7 = 4 so 40+4 ,= 44
then we should do subtracting so, 10-8 = 2
to conclude we should bring the equation to an end so,
44+2 = 46
