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

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]
Make 'y' the subject of the equation. x = 2y -7
Answer:
y = (x + 7)/2
here's your solution
=>. it is given. x = 2y - 7
=> we have to make y as subject
=> now, we can writ this equation in this way
=> 2y - 7 = x
=> now put all constant to right side
=> 2y = x +7
=>. y = x+ 7 /2

Area = L * W
(x^2- 6x - 7) = L * (x - 7)
(x - 7)(x + 1) = L * (x - 7)
(x - 7)(x + 1)
========= = L
(x - 7)

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

∠A and \angle B∠B are supplementary angles. If m\angle A=(7x+24)^{\circ}∠A=(7x+24) ∘ and m\angle B=(7x-26)^{\circ}∠B=(7x−26) ∘ , then find the measure of \angle A∠A.
Answer:
115degrees
Step-by-step explanation:
Given the following angles
m<A=(7x+24)°
m<B=(7x-26)°
Since both angles are supplementary, their sum will be 180 degrees
Taking the sum of the angles
m<A + m<B = 180
7x+24 + 7x - 26 = 180
14x - 2 = 180
14x = 180+2
14x = 182
x = 182/14
x = 13
get m<A
m<A = 7x+24
m<A = 7(13) + 24
m<A = 91 + 24
m<A = 115
Hence the measure of angle m<A is 115degrees
Can someone help me pls
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 )

What is the equation of the midline for the function f(x)? f(x)=1/2cos(x)+5
Answer: y=5
Step-by-step explanation:
At x = 0 and y = 5.5 the equation of the midline for the function
[tex]f(x)= \frac{1}{2} cos(x)+5[/tex] .
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign. For example, 3x – 5 = 16 is an equation.
Is the cos graph symmetrical?
The function cos x is even, so its graph is symmetric about the y-axis.
According to the question
[tex]f(x)= \frac{1}{2} cos(x)+5[/tex]
as cos x is symmetric about y axis
So,
By plotting the graph
we can see that at point x = 0
y = 5.5 is the mid point of this equation
Hence, x = 0 and y = 5.5 the equation of the midline for the function
[tex]f(x)= \frac{1}{2} cos(x)+5[/tex] .
