B. A spinner divided into 5 congruent sectors, spun 4 times
Have a good day
The correct answer is “a spinner divided into 5 congruent sectors, spun 4 times”
What is probability?Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.
Given that, A restaurant owner has found that 80% of her customers return to the restaurant within two weeks. She wants to create a tool that will simulate the habits of her customers and allow her to predict the probability that three of the next four customers to visit her restaurant will return within two weeks.
The correct spinner to use among the 4 should have a probability of winning of 80%, similar to what the owner has found out. So, we must calculate the probability of each spinner.
1. Spun 3 times, and chance of winning is 1 in 5, therefore P = (3) (1/5) = 0.6 = 60%
2. Spun 4 times, and chance of winning is 1 in 5, therefore P = (4) (1/5) = 0.8 = 80%
3. Spun 3 times, and chance of winning is 1 in 2, therefore P = (3) (1/2) = 1.5 = 150%
4. Spun 4 times, and chance of winning is 1 in 2, therefore P = (4) (1/2) = 2 = 200%
We can see that there is only 1 choice that has 80% probability,
Hence, the correct answer is “a spinner divided into 5 congruent sectors, spun 4 times”

A rectangular picture frame has a perimeter of 58 inches. The height of the frame is 14 inches. What is the width of the frame?
Answer:
15
Step-by-step explanation:
14+14=28
58-28=30
30/2=15
Answer:
Step-by-step explanation:
the perimeter of the rectangle is in this case
P=2h+2w
58=2(14)+2w
58=28+2w
58-28=2w
30=2w
w=30/2=15
which is 1/3 - 1/6 in a fraction
Answer:
Step-by-step explanation:
1/3 - 1/6
2/6 -1/6= 1/6
find common denominator
For [tex]\dfrac{1}{3}-\dfrac{1}{6}[/tex] the fraction will be [tex]\dfrac{1}{6}[/tex] .
Given to us,
[tex]\dfrac{1}{3}-\dfrac{1}{6}[/tex]
To solve this, firstly we need to make the denominators the same, thus taking the LCM of both 3 and 6.
As we know the LCM of 3 and 6 is 6 itself.
So, multiplying and dividing by 2.
[tex]\dfrac{1}{3}\rightarrow \dfrac{1\times 2}{3\times 2}\rightarrow \dfrac{2}{6}[/tex]
Now,
[tex]\dfrac{2}{6}-\dfrac{1}{6} = \dfrac{1}{6}[/tex]
Hence, for [tex]\dfrac{1}{3}-\dfrac{1}{6}[/tex] the fraction will be [tex]\dfrac{1}{6}[/tex] .

(TV ) ⃗ bisects ∠STU,m∠STV=(1/4 x+8)°,
and m∠UTV=(x+2)°.Find m∠STU.
Answer:
m∠STU = 20 °
Step-by-step explanation:
Since the line bisects the angle, we have that the two bisected angles are equal
Thus, mathematically;
x + 2 = x/4 + 8
Multiply through by 4
4x + 8 = x + 32
4x-x = 32-8
3x = 24
x = 24/3
x = 8
So to find the value of the original angle, we input 8 into each of the bisected angles and add together
mathematically, that will be ;
10 + 10 = 20

Answer:
x-intercept= -6 & y-intercept = 8
Step-by-step explanation:
To find the intercepts you just have to put the opposite value as 0 in the equation.
X-intercept:
-4x + 3(0) = 24
Y-intercept:
-4(0) + 3y = 24
Everything times 0 is 0, so it cancels out.
Then it is just simple dividing.

Just remember this (x,y)
-X-intercept point (?,0)
-Y-intercept point (0,?)

Answer:
Angle B = 131 degrees
Step-by-step explanation:
We know that since there's an angle labeled 139 degrees and a straight line is 180 degrees in total, the other angle is equal to 180 - 139 = 41 degrees.
Since all triangles have 3 angles that add up to 180 degrees and we know that theres a right angle, a 41 degree angle, then angle A must equal to 180 - 41 - 90 = 49 degrees.
We know that vertical angles are congruent, therefore angle C is also equal to 49 degrees.
Angle B and angle A form a straight line, which we have defined as 180 degrees.
180 - 49 = 131 degrees.
Angle B = 131 degrees
