If "np is greater than or equal to 15" and "n(1-p) is greater than or equal to 15", what is the approximate shape of the sampling distribution of the sample proportion?
Answer:
The sampling distribution of the sample proportion will be approximately normally distributed with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]
Step-by-step explanation:
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
If np >= 15 and n(1-p) >= 15
Can be approximated to the normal distribution, with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]
So
The sampling distribution of the sample proportion will be approximately normally distributed with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]
Rosalia passed out fliers that say, “Vote for Rosalia!” She gave out 85 fliers on Monday, 66 fliers on Tuesday, and 99 fliers on Wednesday. What fraction of the fliers did she give out on Wednesday? Use a diagonal fraction bar in your answer. Explain how you found the answer.
Answer:
She gave out a total of 250 fliers and 99 of them were given out Wednesday. The fraction for that would be 99/250.
Step-by-step explanation:
Consider the provided information.
She gave out 85 fliers on Monday 66 fliers on Tuesday, and 99 fliers on Wednesday.
Now, calculate the total number of fliers she give:
She give 250 fliers in total.
We need to find the fraction of the fliers she give out on Wednesday.
On Wednesday she give 99 fliers and total she give 250 fliers.
99/250
Hence, she give out 99/250 fraction of fliers on Wednesday.

divide -2x^3-5x^2+4x+2 by x+2
To divide the given polynomial by x + 2, use polynomial long division, which involves dividing the leading term, multiplying the divisor, subtracting, and repeating the process until all dividend terms are addressed.
To divide the polynomial -2x^3 - 5x^2 + 4x + 2 by x + 2, we can use the process of polynomial long division. This method is similar to long division with numbers, where we divide, multiply, subtract, bring down the next term, and repeat the process until we have gone through all terms of the dividend.
The process would look like this:
Divide the first term of the dividend (in this case, -2x^3) by the first term of the divisor (x), yielding -2x^2.Multiply the entire divisor (x + 2) by this quotient (-2x^2) and subtract the result from the dividend.Bring down the next term of the dividend and repeat the process until there are no terms left to bring down.The final result would be the quotient of the division, which may or may not have a remainder.
High statement is true? Y=log10^x is not a logarithmic function because the base is greater than 0
Answer:
Option 3 - [tex]y=\log_{1}x[/tex] is not a logarithmic function because the base is equal to 1.
Step-by-step explanation:
To find : Which statement is true?
Solution :
As the function defined in all statement is logarithmic function.
So, The definition of logarithmic function is defined as
[tex]y=\log_bx\Rightarrow b^y=x[/tex] where, b>0 and b ≠ 1.
Now, The following statement
1) [tex]y=\log_{10}x[/tex] is not a logarithmic function because the base is greater than 0.
The statement is False as by definition, the base of a log must be greater than zero but cannot equal one.
2) [tex]y=\log_{\sqrt3}x[/tex] is not a logarithmic function because the base is a square root.
The statement is False as by definition, the base [tex]\sqrt3[/tex] is a positive number not equal to one.
3) [tex]y=\log_{1}x[/tex] is not a logarithmic function because the base is equal to 1.
The statement is True as by definition log cannot have a base of one.
4) [tex]y=\log_{\frac{3}{4}}x[/tex] is not a logarithmic function because the base is a fraction.
The statement is False, as 3/4 is a legitimate base, just like any other positive number other than one.
Therefore, Option 3 is true.
Y=10x

A rectangle is 5 centimeters long and 4 centimeters wide. What is its area?
The area of a circle (A) is given by the formula A=pi*r2
where r is the circle's radius. The formula to find r is . If and , r is centimeters.
The area of a circle is calculated with the formula A = πr², where pi is the mathematical constant approximately equal to 3.14159 and r represents the circle's radius. Considering significant figures is crucial for maintaining precision, as demonstrated in rounding the calculated area of a circle with radius 1.2 m to 4.5 m², based on the initial data's precision.
Explanation:The area of a circle is calculated using the formula A = πr², where π (pi) is a constant approximately equal to 3.14159, and r is the radius of the circle. When calculating the area with a given radius, it's important to consider the significance of figures in your final answer. For instance, if a circle's radius is given as 1.2 meters (with two significant figures), and you calculate the area to be 4.5238934 square meters using a detailed value of pi, you need to round your final answer to maintain the precision of your initial data, resulting in an area of 4.5 m².
It's also valuable to note how ancient civilizations, like the Greeks, approximated mathematics related to circles and how such estimations have evolved into our modern understanding, where the concept of significant figures plays a critical role in ensuring accuracy across varying fields of study and applications.
The pyramid shown has a square base that is 1212 centimeters on each side. The slant height is 1818 centimeters. What is the surface area of the pyramid?
Answer : Surface area of pyramid = 4406832 square cm.
Explanation :
Since we have given that
Side of square base = 1212 cm
Slant height of pyramid = 1818 cm
As we know that ,
[tex]\text{Surface area of pyramid }=\frac{1}{2}\times perimeter\times \text{ slant height}[/tex]
[tex]\text{ Since, perimeter of square }=4\times side\\=4\times 1212\\=4848 cm[/tex]
Now,
[tex]\text{ Surface area of pyramid }= \frac{1}{2}\times 4848\times 1818\\\\\text{ Surface area of pyramid }=4406832\text{ square cm}[/tex]
Hence, surface area of pyramid = 4406832 square cm.

A lake near the Arctic Circle is covered by a 2-meter-thick sheet of ice during the cold winter months. When spring arrives, the warm air gradually melts the ice, causing its thickness to decrease at a constant rate. After 3 weeks, the sheet is only 1.25 meters thick. Let S(t) denote the ice sheet's thickness S (measured in meters) as a function of time t (measured in weeks). Write the function's formula.
Answer: The required function formula is,
S(t) = 2 - 0.25 t
Step-by-step explanation:
Here, the initial thickness of the ice sheet = 2 meters,
After 3 weeks, the thickness of ice sheet = 1.25 meters
Total changes in the thickness in 3 weeks = 2 - 1.25 = 0.75 meters,
⇒ Total changes in the thickness in 1 weeks = 0.75/3 = 0.25 meters,
Since, the ice is melting with the constant rate.
⇒ The rate of ice decreasing = 0.25 meters per week.
⇒ Total changes in t weeks = 0.25 t meters
The new thickness of ice after t weeks = Initial thickness - Total changes in t weeks.
⇒ S(t) = 2 - 0.25 t
Which is the required function's formula.
The function's formula for the ice sheet's thickness as a function of time is S(t) = -0.25t + 2.
Explanation:To write the function's formula, we can use the slope-intercept form of a linear equation, which is given by the equation y = mx + b, where m is the slope and b is the y-intercept. In this case, the slope represents the rate at which the ice thickness decreases over time. From the given information, we know that the thickness decreases by 0.75 meters over 3 weeks. Therefore, the slope is -0.75/3 = -0.25 meters per week.
Since the ice thickness is 2 meters in the beginning, the initial point on the graph is (0, 2). Using the slope-intercept form, we can write the formula for the ice sheet's thickness as a function of time as:
S(t) = -0.25t + 2
