You toss two number cubes. If a sum of 7 or 11 comes up, you get 7 points, if not you lose 2 points.
The probabilities for each of the sums is:
P(2) = 1/36 P(3) = 1/18 P(4) = 1/12 P(5) = 1/9
P(6) = 5/36 P(7) = 1/6 P(8) = 5/36 P(9) = 1/9
P(10) = 1/12 P(11) = 1/18 P(12) = 1/36
The probability of a sum of 7 or 11 is:
1/36
Answer:
2/9Step-by-step explanation:
The probability of a sum of 7 or 11 is the sum of each probability:
P(sum of 7 or 11) = P(7) + P(11) = 1/6 + 1/18 = 3/18 + 1/18 = 4/18 = 2/9Answer:
the first part is 2 / 9
the second part is 0

??????????????????????
Answer:
I belive the answer would be the first one. 2^28 x 3^20 x 9^4
Step-by-step explanation:
This is becasue you need to multiply the power on the outside of the parenthesis, (4). 7 times itself 4 times is 28, 5 times itself 4 times is 20, and then use the 4 for the 9. Hope this helps!

Somebody please help me! Question is due in 11 minutes!
Answer:
Step-by-step explanation:
6. When solving for the value of x in the equation, Martha wrote the following lines on the board.
Step 1 4(x - 1) + 3 = 18
Step 2 4(x - 1) = 15
Step 3 4x - 1 = 15
Step 4 4x = 16
Step 5 x = 4
Which property was used incorrectly when going from Step 2 to Step 3?
a. Addition Property of Equality
b. Distributive Property of Equality
c. Substitution Property of Equality
d. Transitive Property of Equality
Answer:
The distributive property is used incorrectly
Step-by-step explanation:
Step 2 should be: 4x-4=15
4x= 19
x=4 3/4 or 19/4
check work by substituting answer for x
4(19/4-1) + 3 = 18
19-4+3=18
18=18

the diameter of a circle is 8 ft. Find the circumferenceto the nearest tenth.
Answer:
25.1 ft
Step-by-step explanation:
To solve for circumference is pretty simple. Just use the equation 2pi r (r=radius, radius is diameter divided by 2).
So essentially, apply to your calculator:
2(3.14)4=25.12
pretty simple! hope this helps!

Answer:
x ≈ 16.6 units
Step-by-step explanation:
The angle between a tangent and the radius at the point of contact is 90° , so
Δ ABC is a right triangle at ∠ B
Using Pythagoras' identity in the right triangle
x² + 7² = 18²
x² + 49 = 324 ( subtract 49 from both sides )
x² = 275 ( take the square root of both sides )
x = [tex]\sqrt{275}[/tex] ≈ 16.6 ( to the nearest tenth )
write the standard form equation of the circle( 7,-5)
Answer:
(x-7)²+(y+5)²=25
Step-by-step explanation:
The standard form of a circle is (x-h)²+(y-k)²=r²
(h,k) is the center
r is the radius
h=7
k=-5
r=5
(x-7)²+(y--5)²=5²
(x-7)²+(y+5)²=25
Can you please help me with this?
Answer:
Step-by-step explanation:
[tex]S^{2}[/tex] is ( [tex]q^{2}[/tex][tex]r^{3}[/tex])^2
then
A = [tex]q^{2*2}[/tex][tex]r^{3*2}[/tex]
A = [tex]q^{4}[/tex][tex]r^{6}[/tex]
this looks much better than r^ some big number :D

A volleyball team played five games. In those games, the team won by 7 points, lost by 3, lost by 2, won by 4, and won by 9. What was the total amount of points from all five games
Answer:
The answer is "3"
Step-by-step explanation:
In essence, it represents the sum of all comments divided by the number of responses.
It implies scoring in the five games corresponds to a total of five results.
Scores :
7 points implies+ 7
lost by 3 implies- 3
lost by 2 implies - 2
won by 4 implies + 4
won by 9 implies + 9
Sum of all scores [tex]= 7 - 3 - 2 + 4 + 9 = 15[/tex]therefore
Its team has a total of 5 games[tex]= 5[/tex]
Measurement in scores in five games thus = sum of all scores/sum with the team played games [tex]=\frac{15}{5}= 3[/tex]

[tex]x {}^{2} = 6 {}^{2} + 8 {}^{2} \\ x { }^{2} = 36 + 64 \\ x {}^{2} = 100 \\ x = \sqrt{100 } \\ x = 10[/tex]
are these lines parallel, perpendicular, or neither?
Answer:
[tex]\Huge\boxed{neither}[/tex]
Step-by-step explanation:
Parallel lines never touch and these lines intersect therefore these are not parallel lines
These lines may intersect but they do not create 90 degree angles which is essential for perpendicular lines and for those reasons the lines shown are not perpendicular lines
So we conclude that the lines shown are neither parallel lines nor perpendicular lines
