The twenty units of potatoes illustrates the measure of central tendency and probability
The modal weight, mean, and medianStart by sorting the dataset:
0.19; 0.28; 0.55;
0.62; 0.68; 0.77;
0.88; 0.89; 0.98;
0.99; 1.11; 1.22;
1.22; 1.22; 1.33;
1.44; 1.48; 1.68;
1.77; 1.99
The highest occuring element is 1.22 with a frequency of 3
The two middle elements are 0.99 and 1.11.
The mean of these two middle elements is: 0.5 * (0.99 + 1.11) = 1.05
The mean of the whole dataset is:
Mean = (0.19+ 0.28+ 0.55+ 0.62+ 0.68+ 0.77+ 0.88+ 0.89+ 0.98+ 0.99+ 1.11+ 1.22+1.22+ 1.22+ 1.33+ 1.44+ 1.48+ 1.68+1.77+1.99)/20
Mean = 1.06
Hence, the modal weight is 1.22, the mean is 1.06, and the median is 1.05
The probabilities(a) at least 1.1 kg
There are 10 potatoes that weigh at least 1.1 kg.
So, the probability is:
P = 10/20
P = 0.5
(b) more than 3.5kg
There are 0 potatoes that weigh more than 3.5 kg.
So, the probability is:
P = 0/20
P = 0
(c) below 0.50kg
There are 2 potatoes that weigh below 0.50 kg.
So, the probability is:
P = 2/20
P = 0.1
The Variance of the weight.
This is calculated as:
Var = [tex]\sum[/tex](x - mean)^2/n
This gives
Var = [(0.19 - 1.06)^2 + (0.28 - 1.06)^2 + (0.55 - 1.06)^2 + (0.62 - 1.06)^2 + (0.68 - 1.06)^2 + (0.77 - 1.06)^2 + (0.88 - 1.06)^2 + (0.89 - 1.06)^2 + (0.98 - 1.06)^2 + (0.99 - 1.06)^2 + (1.11 - 1.06)^2 + (1.22 - 1.06)^2 + (1.22 - 1.06)^2 + (1.22 - 1.06)^2 + (1.33 - 1.06)^2 + (1.44 - 1.06)^2 + (1.48 - 1.06)^2 + (1.68 - 1.06)^2 + (1.77 - 1.06)^2 + (1.99 - 1.06)^2]/20
Evaluate
Var = 0.22

This problem is attempting to explain the distributive property to you.
The distributive property states that if you have the numbers a, b, and c:
[tex](a*c) + (b*c) = c * (a+b)[/tex]
In your specific case, this would look like this:
[tex](23+37) * 4\frac{1}{6}[/tex]
[tex]60 * \frac{(4*6)+1}{6}[/tex]
[tex]60*\frac{25}{6}[/tex]

It is estimated that 60% of U.S. households subscribe to cable TV. You would like to verify this statement for your class in mass communications. If you want your estimate to be within 5 percentage points, with a 95% level of confidence, how many households should you sample
Using the z-distribution, as we are working with a proportion, it is found that you should sample 577 households.
What is a confidence interval of proportions?A confidence interval of proportions is given by:
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which:
[tex]\pi[/tex] is the sample proportion.z is the critical value.n is the sample size.The margin of error is given by:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In this problem, we have a 95% confidence level, hence[tex]\alpha = 0.95[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so the critical value is z = 1.96.
In this problem, the estimate is of [tex]\pi = 0.6[/tex], and we want a margin of error of M = 0.05, hence we solve for n to find the sample size.
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.05 = 1.96\sqrt{\frac{0.6(0.4)}{n}}[/tex]
[tex]0.05\sqrt{n} = 1.96\sqrt{0.6(0.4)}[/tex]
[tex]\sqrt{n} = \frac{1.96\sqrt{0.6(0.4)}}{0.05}[/tex]
[tex](\sqrt{n})^2 = \left(\frac{1.96\sqrt{0.6(0.4)}}{0.05}\right)^2[/tex]
[tex]n = 576.24[/tex]
Rounding up, you should sample 577 households.

a triangle banner is to be made according to the specifications in the figure shown with dimensions given in inches. WOODEN STICKS WILL BE USED TO OUTLINE THE PERIMETER of the banner in order to attach the interior material. How many inches of wooden sticks will be required?
Applying the Pythagorean theorem, the amount of inches of wood required = Perimeter of triangle = 15 + 13 + 9 = 37 inches.
What is the Pythagroean Theorem?The Pythagorean theorem is used to find a side of a right triangle, and it states that if c is the hypotenuse and a and b are the other legs, therefore: c² = a² + b².
Find the altitude/height of the triangle using the Pythagorean theorem:
height = √(13² - 5²)
height = 12
Also, use the Pythagorean theorem to find the missing side (part of the longest side of the main triangle):
missing side = √(15² - 12²) = 9
Amount of inches of wood required = Perimeter of triangle = 15 + 13 + 9 = 37 inches.

1. Solve 2(x + 1)^2 = 18. What are the x-intercepts?
Answer:
The x-intercepts are [tex](2,0)[/tex] and [tex](-4,0)[/tex].
Step-by-step explanation:
We are given the equation
[tex]2(x+1)^2=18[/tex]
Begin by dividing both sides of the equation by 2:
[tex](x+1)^2=9[/tex]
Next, take the square root of both sides. Remember that there are two solutions to a square root, the positive and the negative root:
[tex]x+1=\pm3[/tex]
Split the equation into two based on the two solutions:
[tex]x+1=-3[/tex]
[tex]x+1=3[/tex]
Solve each equation by subtracting 1 from both sides:
[tex]x=-4\\ x=2[/tex]
Since the x-intercepts are the solutions to a quadratic, we know the solutions are (2,0) and (-4,0).
The length of a rectangle is six times its width.
If the perimeter of the rectangle is 84 in, find its area.
Step-by-step explanation:
Length = 6x
width = let x be width
Perimeter = 84 in
Now
Perimeter = 2 ( l + b )
84 = 2 ( 6x + x )
84 = 2 × 7x
84 / 2 = 7x
42 = 7x
x = 42 / 7
x = 6
now
width = 6 yards
length = 6x = 6 × 6 = 36 yards
now
area = l × b
= 6 × 36 yd
= 216 yd²
