Probability is the likelihood that an event will occur and is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.
It is given that, there is \($25$\) sundaes with mint, chocolate and vanilla flavor ice cream out of these \($\frac{3}{5}$\) of the sundaes are mint flavor and \($\frac{1}{2}$\) are chocolate flavor.
We have to find the number for sundaes will be vanilla flavor ice-cream.
So,
We have to multiply \($3$\) by \($5$\) and solve it.
So,
\($3\times 5=15$\)
There are \($15$\) mints flavor.
Now,
Divide total number of sundaes with all flavor ice-cream by calculate value for mint.
We get,
\($25-15=10$\)
Multiply the above calculate value by no. of remaining sundaes for chocolate ice-cream.
So,
\($10\times \frac{1}{2}=5$\)
Hence, there are \($5$\) sundaes will be vanilla flavor ice-cream.

Answers
Here are the pairs matched with their products:
- (-5)(4.2) matches with -21
- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.

Answer:
Step-by-step explanation:
11. -1= (5+x)/6 : to get rid of the 6 on the bottom multiply to both sides.
-6=5+x : subtract 5 to both sides
-11 = x
12. 2/3x + 2 = -4 : subtract the 2 to both sides
2/3x = -6 : divide 2/3 to both sides
x= -6/(2/3)
x=-9
13. 7x+2.5=-4.5 : subtract 2.5 to both sides
7x= -7 : divide by 7 to both sides
x= -1
14. 8-3/8x= -4 : subtract 8 to both sides
-3/8x = -12 : divide both sides by -3/8
x=32 : two negatives make a positive
15. -3x - 5 = -38 : add 5 to both sides
-3x=-33 : divide both sides by -3
x= 11 : two negatives make a positive

Answers
For Mountain View School:
Data: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 0 + 1 + 2 + 3 + 4 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 8 + 8 + 8 + 9) / 19
= 100 / 19
≈ 5.26
To find the median, we need to arrange the data in ascending order: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5
For Seaside School:
Data: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 1 + 1 + 2 + 2 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 7 + 8 + 8 + 8 + 9) / 19
= 80 / 19
≈ 4.21
To find the median, we need to arrange the data in ascending order: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5
Now let's calculate the measures of variability, specifically the range and interquartile range (IQR).
Range: The range is the difference between the largest and smallest values in the dataset.
For Mountain View School:
Range: 9 - 0 = 9
For Seaside School:
Range: 9 - 0 = 9
Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1) and measures the spread of the middle 50% of the data.
For Mountain View School:
Q1 = 3
Q3 = 7
IQR = Q3 - Q1 = 7 - 3 = 4
For Seaside School:
Q1 = 2
Q3 = 7
IQR = Q3 - Q1 = 7 - 2 = 5
To determine which school is a better choice for a smaller class size, we can consider both the mean and the median.
Both the mean and median for Mountain View School are higher than those for Seaside School. This suggests that, on average, the class sizes at Mountain View School are larger than those at Seaside School. Therefore, if you are interested in a smaller class size, Seaside School would be a better choice
For Mountain View School:
- Median: The median class size is the middle value, which is 25.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (29 + 28 + 28 + 27 + 25 + 24 + 24 + 23 + 21 + 20 + 19 + 18 + 15 + 13 + 10) / 15 = 21.27.
For Seaside School:
- Median: The median class size is the middle value, which is 20.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (25 + 25 + 27 + 27 + 28 + 28 + 28 + 30 + 31 + 35 + 36 + 38 + 40 + 43 + 45) / 15 = 31.13.
Part B:
For Mountain View School:
- Range: The range is the difference between the largest and smallest values, which is 29 - 10 = 19.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 20 and Q3 is 28. Therefore, the IQR is 28 - 20 = 8.
For Seaside School:
- Range: The range is the difference between the largest and smallest values, which is 45 - 25 = 20.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 27 and Q3 is 38. Therefore, the IQR is 38 - 27 = 11.
Part C:
If you are interested in a smaller class size, Mountain View School is a better choice for you because it has a lower mean and median class size than Seaside School.

Next, we find the value of the three of them combined.

Now, we find the value of the smaller triangle.

Because we only have one small triangle, we don't need to do what we did with the other one now.
The last step is to add the area of the three triangles with the smaller triangle.

The circumference of a circular park is approximately 18 feet. What is the approximate area inside the circular park?
Answers
Answer:
25.685 square feet.
Step-by-step explanation:
Circumference = 2 * π * radius
From this, we can derive the formula for the radius:
radius = Circumference / (2 * π)
Let's substitute the value of the circumference and calculate the approximate radius:
radius = 18 / (2 * π)
radius ≈ 18 / (2 * 3.14159)
radius ≈ 2.865 feet
Now that we have the approximate radius, we can calculate the area:
Area ≈ π * radius²
Area ≈ 3.14159 * (2.865)²
Area ≈ 3.14159 * 8.193225
Area ≈ 25.685 square feet
Therefore, the approximate area inside the circular park is approximately 25.685 square feet.
C = 2πr
where C is the circumference and r is the radius of the circle.
In this case, we are given that the circumference is approximately 18 feet, so we can set up the following equation:
18 = 2πr
Solving for r, we get:
r = 9/π ≈ 2.864 feet
Now we can use the formula for the area of a circle:
A = πr^2
Substituting the value we found for r, we get:
A = π(2.864 ft)^2 ≈ 25.85 ft^2
Therefore, the approximate area inside the circular park is approximately 25.85 square feet.
The Bradenton Post polled 1,356 adults in the city to determine whether they wet their toothbrush before they put toothpaste on it. Of the respondents, 54% said they wet it first. Suppose 68% of all adults actually wet their toothbrush first. What are the mean and standard deviation of the sampling distribution?
Answers
Answer:
deviation = -95.50147493 mean = 61
Step-by-step explanation:
54% wet there brushes first
suppose 68% wet there brushes what is the mean
mean: a mean is where you add both numbers together to get a total then divide by how many numbers you added for now we wont need the amount of people we just need the percentages for this
54 + 68 = 122
we added to numbers so well divide by 2
122 divided by 2 or 122/2 is equal to 61
61 is our mean
standard deviation : this is were you take the known average 1356 adults and subtract the mean
1356- 61 = 1295 then divide by 1356 and times by 100
if the number is positive then the mean is higher than expected but luckily its a negative so its -95.50147493

Step-by-step explanation:
What is linear function?
Linear function is the function in which the highest power of the unknown variable is one. Linear functions are used to model the real life problem in the mathematical expressions.
The linear function with dependent variable y and independent variable x can be written as,
Here, (m) is the slope of the function and (b) is the y intercept.
As the car is moving at a constant speed passes a timing device at t=0.
After 8 seconds the car has traveled 840 feet.
To construct the equation of linear function, we have to find the point of it.
One point of the line is (0, 0) as the car move 0 distance at 0 time.
Another point of the line is (8, 840) as after 8 seconds the car has traveled 840 feet.
From the equation of linear line,
Here, the s the distance in the feet, d, the car has traveled any number of seconds, t, after passing the timing device. Thus the function can be written as,
Thus the linear function in the form y=mx+b represents the distance in the feet, d, the car has traveled any number of seconds, t is,
