What is a Pareto chart?A Pareto chart is known to be a form of a bar graph.
It is made up of different lengths of bars that stands for frequency or cost ( e.g. time or money, and are said to be placed with longest bars on the left and then the shortest are placed to the right.

In a random sample of 1214 eligible voters younger than 40 years old, 461 reported that they planned to vote in the upcoming election. In a random sample of 1098 voters 40 and older,560 reported that they planned to vote in the election. Construct a 90% confidence interval for the difference between the percent of all voters younger than 40 and 40 and older who plan to vote in the upcoming election. What critical z-score will be used
Using the z-distribution, with a critical z-score of z = 1.645, the 90% confidence interval is (-16.4%, -9.66%).
What are the mean and the standard error for the distribution of the difference of proportions?For each sample, the mean and the standard error are given as follows:
[tex]p_y = \frac{461}{1214} = 0.3797, s_y = \sqrt{\frac{0.3797(0.6203)}{1214}} = 0.0139[/tex].[tex]p_o = \frac{560}{1098} = 0.51, s_o = \sqrt{\frac{0.51(0.49)}{1098}} = 0.0151[/tex].Hence, for the distribution of differences, they are given as follows:
[tex]p = p_y - p_0 = 0.3797 - 0.51 = -0.1303[/tex].[tex]s = \sqrt{s_y^2 + s_o^2} = \sqrt{0.0139^2 + 0.0151^2} = 0.0205[/tex]What is the confidence interval?
The interval is:
[tex]p \pm zs[/tex]
In this problem, we have a 90% confidence level, hence[tex]\alpha = 0.9[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.9}{2} = 0.95[/tex], so the critical value is z = 1.645.
Then the bounds of the interval are:
p - zs = -0.1303 - 1.645(0.0205) = -0.164.p + zs = -0.1303 + 1.645(0.0205) = -0.0966.As a percentage, the 90% confidence interval is (-16.4%, -9.66%).

Find: AL
AL= __cm
Please answer in detail ASAP thank you so much it would help a lot <3
The value of line AL is 21. 51cm
How to determine the lengthTo find line AL,
Using
Sin α = opposite/ hypotenuse to find line AB
Sin 90 = x/ 24
1 = x/24
Cross multiply
x = 24cm
Now, let's find line AC
Sin angle B = line AC/24
Note that to find angle B
angle A + angle B + angle C = 180
But angle B = 2 Angle A
x + 2x + 90 = 180
3x + 90 = 180
3x = 180-90
x = 30°
Angle B = 2 × 30 = 60°
Sin 60 = x/ 24
0. 8660 = x/24
Cross multiply
x = 24 × 0. 8660
x = 20. 78cm
We have the angle of A in the given triangle to be divide into two by the bisector, angle A = 15°
To find line AL, we use
Cos = adjacent/ line AL
Cos 15 = 20. 78/ line AL
Line AL = 20. 78/ cos 15
Line AL = 20. 78 / 0. 9659
Line AL = 21. 51 cm

The table below gives recommended weight ranges for the balls from five different sports. (Hint: Find the average of each weight.)
The average weights of each ball are 270 grams, 625 grams, 425 grams, 145.5 grams and 14.5 ounces
How to determine the average weights?The range is given as:
Sport Weight range of ball used
Volleyball 260-280 grams
Basketball 600-650 grams
Water Polo 400-450 grams
Lacrosse 142-149 grams
Football 14-15 ounces
The average of each weight is calculated as:
Average = (Max + Min)/2
So, we have:
Volleyball = (260+280)/2 = 270 grams
Basketball = (600+ 650)/2 = 625 grams
Water Polo = (400+450)/2 = 425 grams
Lacrosse = (142+149)/2 = 145.5 grams
Football = (14+15)/2 = 14.5 ounces
Hence, the average weights of each ball are 270 grams, 625 grams, 425 grams, 145.5 grams and 14.5 ounces

Determine an angle between 0° and 360° that is coterminal to an angle with measure of 1524°.
Enter your answer below without a degrees symbol - just enter the numeric answer.
Answer: 84°
Step-by-step explanation:
On a unit circle, coterminal angles are angles that are in the opposite position of the asked angle. 1524° revolves around 127/15π times across the entire unit circle.
84° is the only positive coterminal angle between 0 and 360 that is in the opposite position of 1524°.
Keep in mind, that there are more coterminal angles, namely 444°, 804°, 1164°, and 1524° itself, but they are outside of the range of 0 and 360 degrees.
