Using the binomial distribution, it is found that the expected values are given by:
a) 120.
b) 150.
What is the binomial probability distribution?It is the probability of exactly x successes on n repeated trials, with p probability of a success on each trial.
The expected value of the binomial distribution is:
E(X) = np
In this problem, for both items, we consider that the number cube is rolled 180 times, hence n = 180.
Item a:
4 of the 6 possible values are greater than 2, hence p = 4/6 = 2/3.
The expected value is given by:
E(X) = 180 x 2/3 = 120.
Item b:
5 of the 6 values are less than 6, hence p = 5/6.
The expected value is given by:
E(X) = 180 x 5/6 = 150.

The function which has zeros at x = 10 and x = 2 is [tex]\rm f(x)=x^2-12x+20[/tex].
What are the zeros of the function?The zero of a function is any replacement for the variable that will produce an answer of zero.
Graphically, the real zero of a function is where the function's graph crosses the x-axis; that is, the real zero of a function is the x-intercept (s) of the function's graph.
The function which has zeros at x = 10 and x = 2 is;
[tex]\rm f(x)=(x-10)(x-2)\\\\f(x)=x(x-2)-10(x-2)\\\\f(x)= x^2-2x-10x+20\\\\f(x)=x^2-12x+20[/tex]
Hence, the function which has zeros at x = 10 and x = 2 is [tex]\rm f(x)=x^2-12x+20[/tex].

[tex]\qquad\qquad\huge\underline{{\sf Answer}}[/tex]
As we can see in the given figure, The two triangles are congruent to each other by many criterias, so we can infer that Their corresponding sides are of equal length.
That is :
[tex]\qquad \tt \dashrightarrow \:2x + 5 = 13[/tex]
[tex]\qquad \tt \dashrightarrow \:2x = 13 - 5[/tex]
[tex]\qquad \tt \dashrightarrow \:2x = 8[/tex]
[tex]\qquad \tt \dashrightarrow \:x = 8 \div 2[/tex]
[tex]\qquad \tt \dashrightarrow \:x = 4[/tex]
Therefore, value of x is 4
Answer:
x = 4
Step-by-step explanation:
the point here is congruent triangles.
according to the image,
2x + 5 = 13 <---- subtract constants
2x = 13 - 5 = 8 <--- finalize
2x = 8 <----------- divide both sides by 2
2x / 2 = 8 / 2 <-- finalize
x = 4 <--- answer
3n + 2 = 8 find answer for n
Answer:
[tex]\boxed{\sf{n=2}}[/tex]Step-by-step explanation:
To solve for n, isolate it on one side of the equation.
3n+2=8First, you have to subtract by 2 from both sides.
[tex]\Longrightarrow: \sf{3n+2-2=8-2}[/tex]
Solve.
Subtract the numbers from left to right.
[tex]\sf{8-2=6}[/tex]
Rewrite the problem.
⇒ 3n=6
Divide by 3 from both sides.
→ 3n/3=6/3
Solve.
Divide the numbers from left to right.
→ 6/3=2
[tex]\Longrightarrow: \boxed{\sf{n=2}}[/tex]
Therefore, the correct answer is n=2.I hope this helps! Let me know if you have any questions.
Answer:
n = 2 or.... n is 2
Step-by-step explanation:
When simplifying to find n, we do something to one side, but it also must be done to the other side. First, to get n alone, we would subtract 2. When doing this, we do it for both sides:
3n + 2 = 8
-2 -2
3n = 6
Now, we divide n by 3 becuase right now it says 3 times n. We again do the same for both sides:
3n = 6
/3 /3
n = 2
So the answer is n = 2
n is 2.

How do you factor (2x^2+2)
Answer:
You factor that equation by seeing if you can take out anything. Example.
20 is the same as 2 times 2 times 5. Visualized, it is 2(10) or 4(5).
For this, you can take out the "2"
So it would be
2(x^2+1)
x^2+1 can't be factored so that is the final answer

apples in the basket was 5 to 2. If there were 70 apples in the basket,
how many of them were red?
The number of apples that are red is 50
Calculating ratioFrom the question, we are to determine the number of apples that are red
From the given information,
The ratio of red apples to green apples is 5:2
∴ Sum of ratio = 5+2 = 7

what does x equal to?
5(x - 4) + 12 = 17
Answer:
x is 5
Step-by-step explanation:
First of all, expand the bracketsThis gives [tex]5x-20+12=17[/tex]Add 20 to both sides[tex]5x+12=37[/tex]Subtract 12 from both sides[tex]5x=25[/tex]Divide both sides by 5[tex]x=5[/tex]Answer:
x = 5Step-by-step explanation:
In the question we're given with an equation that is 5(x - 4) + 12 = 17 and we are asked to find the value of x .
Solution : -
[tex] \longmapsto \: 5(x - 4) + 12 = 17[/tex]
Step 1 : Solving parenthesis :
[tex] \longmapsto \:5x - 20 + 12 = 17[/tex]
Step 2 : Adding 20 on both sides :
[tex] \longmapsto \:5x - \cancel{20 }+ 12 + \cancel{20 }= 17 + 20[/tex]
[tex] \longmapsto \:5x + 12 = 37[/tex]
Step 3 : Subtracting 12 from both sides :
[tex] \ \longmapsto \: \:5x + \cancel{ 12} - \cancel{12} = 37 - 12[/tex]
[tex] \longmapsto \:5x = 25[/tex]
Step 3 : Dividing by 5 on both sides :
[tex] \longmapsto \: \frac{ \cancel{5}x}{ \cancel{5} } = \cancel\frac{25}{5} [/tex]
[tex] \longmapsto \: \red{ \boxed{\bold{x = 5}}}[/tex]
Therefore , value of x is 5Verifying :
We are verifying our answer by substituting value of x in Given Equation :
5(x - 4) + 12 = 175 ( 5 - 4 ) + 12 = 175 ( 1 ) + 12 = 175 + 12 = 1717 = 17L.H.S = R.HS.Hence, Verified.Therefore , our value for x is correct .

three friends Luke nick and serena are kicking a soccer ball to each other on the beach Luke kicks the ball to Serena who kicks the ball to nick, who kicks the ball back to Luke. the friends location on the beach are drawn on a coordinate plane as shown where the x values and y represent distance in feet.
WHAT IS THE APPROXIMATE DISTANCE THE BALL TRAVELS AFTER MAKING A FULL ROTATION AROUND THE TRIANGLE OF FRIENDS?
A. 288 feet
B.57.94 feet
C. 144 feet
D. 67.91 feet
The approximate distance the ball travels after making a full rotation around the triangle of friends is approximately 56.25 feet.
The closest option to this value is option B: 57.94 feet.
To find the approximate distance the ball travels after making a full rotation around the triangle of friends, we need to calculate the sum of the distances between each pair of friends.
Distance between Luke and Serena:
√[(4 - 4)² + (9 - (-14))²]
= √(0 + 23²)
= √529
= 23 feet
Distance between Serena and Nick:
√[(4 - (-8))² + ((-14) - (-2))²]
= √(12² + (-12)²)
= √(144 + 144)
= √288
= 16.97 feet (approx.)
Distance between Nick and Luke:
√[((-8) - 4)² + ((-2) - 9)²]
= √((-12)² + (-11)²)
= √(144 + 121)
= √265
= 16.28 feet (approx.)
Now, to get the approximate total distance traveled, we add the distances together:
Total distance ≈ 23 + 16.97 + 16.28
= 56.25 feet
The approximate distance the ball travels after making a full rotation around the triangle of friends is approximately 56.25 feet.
The closest option to this value is option B: 57.94 feet.
