Your team is in charge of games at the Amusement Park. One of the games involves a robotic arm that randomly grabs a stuffed animal out of a large bin. You need to set up the game so that the probability of a customer’s grabbing a teddy bear is exactly 1/2
a. how would you set up the bin? Explain.
B. What if you returned to check on the bin and found that there are 4 teddy bears left and 12 other animals? What could you add to or remove from the bin to return the probability of selecting a teddy bear to 1/2?
Answer:
a. I would put 20 stuffed animals in the bin, out of which 10 would be teddy bears.
So that the probability is 10/20 = 1/2
b. I could remove 8 other animals from 12 to have 4. So that the total number of stuffed animals is 8. 4/8 = 1/2
Step-by-step explanation:
a. Probability =
number of required outcomes / number of possible outcomes
If in the bin there are 10 teddy bears out of 20 stuffed animals,
Then the probability of picking a teddy bear = 10/20 = 1/2.
b. If on returning, there are 4 teddy bears and 12 other animals, I could simply remove 8 of the other animals to have 4 other animals and a total of 8 stuffed animals.
Probability = 4/8 = 1/2

Step-by-step explanation:
[tex]2x+7-6x=23[/tex]
[tex]-4x+7=23[/tex]
[tex]-4x=16[/tex]
[tex]x=-4[/tex]
Answer:
x=-4
Step-by-step explanation:
2x+7−6x=23
Step 1: Simplify both sides of the equation.
2x+7−6x=23
2x+7+−6x=23
(2x+−6x)+(7)=23(Combine Like Terms)
−4x+7=23
−4x+7=23

−4x+7−7=23−7
−4x=16
Step 3: Divide both sides by -4.

Let the number of fishes Ms. Montesinos has be represented by = f
b) Set up an equation using the variable you defined in (a):
The equation is :
3f - 2 = 13
c) Solve your equation & Check. How many fish does Ms. Montesinos have?
Ms. Montesinos has 5 fishes
Step-by-step explanation:
Ms. Cruz has a tank with 11 fish. After buying two more, she has 2 less than triple the amount of fish Ms. Montesinos has. How many fish does Ms. Montesinos have in her tank?
a) Write a let statement below to define your variable(s):
Let the number of fishes Ms. Montesinos has be represented by = f
b) Set up an equation using the variable you defined in (a):
We are told in the question:
Ms. Cruz has a tank with 11 fish. After buying two more, she has 2 less than triple the amount of fish Ms. Montesinos has.
Therefore,
3× f - 2 = 11 + 2
The equation is :
3f - 2 = 13
c) Solve your equation & Check. How many fish does Ms. Montesinos have?
Solving the above equation:
3f - 2 = 13
3f = 13 + 2
3f = 15
Divide both sides by 3
3f/3 = 15/3
f = 5
Hence, Ms. Montesinos has 5 fishes

9514 1404 393
Answer:
560 +32x
Step-by-step explanation:
There are a number of ways the area can be subdivided. In order to minimize the number of expressions involving x, we choose to divide it this way:
Create a rectangle 52 yd by 40 yd that encloses the figure along with the empty space above the left side of the figure.
Subtract a rectangle whose dimensions are (40-x) by (52 -20) in the upper left corner of the previous rectangle.
Subtract a rectangle whose dimensions are 10 by 24 in the center of the figure.
Then the total area of the parking lot is ...
52·40 -(40-x)(32) -10·24 = 2080 -1280 +32x -240 = 560 +32x
The area of the parking lot is 560+32x square yards.
Two angles of a triangle have measures of 30° and 45°.
What is the measure of the remaining angle?
Enter the correct answer in the box.
Answer:
30+45+x=180(sum of all angles of triangle is equal to 180 degree)
75+x=180
x=180-75
x=105
The measure of the third interior angle is 105°.
What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
We also know that the sum of all the interior angles of a triangle is 180°.
Given, Two angles of a triangle have measures of 30° and 45°, assuming the third angle to be x.
∴ 30° + 45° + x = 180°.
x + 75° = 180°.
x = 180° - 75°.
x = 105°.
So, the measure of the third angle is 105°.

The record of an athlete shows that she scores 0.82 of the points she attempts to make. What is the probability that she makes her first point on attempt number 4?
Answer:
The probability is 0.00478224
Step-by-step explanation:
Probability of scoring an attempt is 0.82
Probability of not is 1-0.82 = 0.18
So making the first point in attempt number 4 means that she failed the first three
So we have the probability as;
0.18 * 0.18 * 0.18 * 0.82 = 0.00478224

Insurance companies use statistical models to assess the risk associated with insuring a particular driver and car, and these models take into account a wide range of factors that are known to impact accident rates and insurance claims.
However, the color of your car is not typically considered a significant factor in determining insurance premiums.
While some people believe that red cars or other bright colors may be more likely to get pulled over or be involved in accidents, there is little evidence to support this idea.

the first photo is number one, and the second photo is number two :)
Answer:
It's the third one down for both of them.
Step-by-step explanation:
1. first count the spaces from each intersection, starting with down. #1 has a slope of 2/3. Since it's leaning to the left, it's a negative. The only one with -2/3 is the third option down.
2. Again, look at the slope. this one is 2/1 (or just 2), and is leaning to the left, so is negative. Since there are multiple with -2 as the slope, we then look at the y-intercept. It's -1. The only answer that lines up perfectly with what we have is the third one down.
