What is the pie chart?A circular data visual with slices illustrating numerical proportions is called a pie chart. Each slice's angle in a pie chart corresponds to the material it represents.
In an election there were four candidates, J, K, L, and M. Teri is drawing a pie chart to show the results. The sectors for J and K have been drawn. Twice as many people voted for L as voted for M.
Let 'x' be the number of people who voted for L and M. Then the number of people who voted for J and K will be 2x.
The angle that needs to be used to draw the sector for L will be given as,
⇒ 360° × [x / (2x + 2x + x + x)]
⇒ 360° × [x / 6x]
⇒ 360° × 1/6
⇒ 60°
Altogether, 15,840 people voted. Then the number of people who voted for J will be given as,
⇒ [(2x) / (2x + 2x + x + x)] × 15,840
⇒ (1/3) × 15,840
⇒ 5,280

Solve the triangle for x.
(View the attachment)
A. 39.4(degrees)
B. 46.5(degrees)
C. 94.1(degrees)
D. 105.9(degrees)
Answer:
Option C
Step-by-step explanation:
By applying cosine rule in the given triangle,
BC² = AB² + AC² - 2(AB)(AC)cosA
(11)² = 8² + 7² - 2(8)(7)cosx
121 = 64 + 49 - 112cos(x)
cos(x) = -[tex]\frac{8}{112}[/tex]
x = [tex]\text{cos}^{-1}(-\frac{1}{14})[/tex]
x = 94.1°
Therefore, Option C will be the correct option.

Americans eat an average of 100 acres of pizza per year. That is equivalent to 4,356,000 square feet of pizza per year. How is the area expressed using scientific notation?
Answer:
D. [tex] 4.356 * 10^6 [/tex] ft²
Step-by-step explanation:
Scientific notation of a number is expressed in the following form, [tex] a * 10^b [/tex]
Where,
a = decimal number (1 ≤ |a| < 10)
b = the power of 10 whereby the scientific notation is equivalent to the original number.
To express 4,356,000 square feet in scientific notation, do the following:
1. Move the decimal point to the left up to the last non-zero digit = a = 4.356
2. Since we moved the decimal point by 6 decimal places, therefore, b = 6
3. Substitute the values of the variables into
Thus:
4,356,000 = 3. Substitute the values of the variables into
a * 10^b
Thus:
4,356,000 = 4.356 * 10^6

For a school newspaper article, Cienna conducted a survey to find out students’ favorite subjects. She polled all the students in Mrs. Lopez’s advanced dance class. Why is her data likely to be skewed?
Honors dance students are more likely to enjoy dance than students in the general population, so dance may be overrepresented.
Cienna should have interviewed all the students in the school to get more accurate data.
Honors dance students are more likely to enjoy dance than students in the general population, so dance will be underrepresented.
Cienna should have interviewed only every other student in the class to avoid having too many people.
Step-by-step explanation:
It's A sorry about that
The data is skewed:
Honors dance students are more likely to enjoy dance than students in the general population, so dance may be overrepresented.
The correct option is A.
What is skewed data?In other words, data with a lower bound are frequently skewed right, and data with an upper bound are typically biased left.
Start-up effects can also cause skewness.
Given:
For a school newspaper article,
Cienna conducted a survey to find out students’ favorite subjects.
She polled all the students in Mrs. Lopez’s advanced dance class.
Lower or higher boundaries on the data frequently cause skewed data.
In other words, data with a lower bound are frequently skewed right, and data with an upper bound are typically biased left.
Start-up effects can also cause skewness.
Students in an advanced dancing class are probably there because they wanted to be there.
Students are not randomly selected to this kind of class.
If you poll students who voluntarily enrolled in the class, the findings will probably prefer the dancing class more than the other subjects.
Therefore, honors dance students are more likely to enjoy dance than students in the general population, so dance may be overrepresented.

______
A. 710
B. 1,358
C. 720
D. 1,368
Answer:
D
Step-by-step explanation:
First, start with the ones column. 2*9 is 18, so write the 8 below and carry the 1 into the tens column. Now, we do 9*7 plus the 1 we carried, so that makes 64. The first row under the line should be 648. Next, annex a zero under the number 648 in the ones column. Now we move to the tens. 1*2 is 2. 1*7 is 7. The number under 648 should be 720. Now, we add 648 and 720. 648+720 is 1,368. 1,368 is our final product, which makes the answer D. I'm sorry if this seemed confusing (it's a bit hard to explain in words), but I hope it helps!
A microwave is placed on top of a stand. The stand is 2 feet 10 inches tall, and the microwave is 3 feet 3 inches tall. Together, how tall are they?
Write your answer in feet and inches. Use a number less than 12 for inches.
Answer:
6 feet 1 inch tall
Step-by-step explanation:
10 inch + 3 inch is 13 inch which is equal to 1 foot 1 inch
2 feet + 3 feet is 5 feet and if we add 5 feet to 1 foot and 1 inch, it will be equal to 6 feet 1 inch.

Please help me! Thank you
(The -x/6 is a fraction in case you thought it was division)
Answer:
x = -156
Step-by-step explanation:
Solve for x by simplifying both sides of the equation, then isolating the variable.
Answer: x=−156
Step-by-step explanation: −x/6 +6=32
−1 /6 x+6−6=32−6
−1 /6 x=26
( 6 /−1 )( −1 /6 x)=( 6 /−1 )(26)

A new reading program may reduce the number of elementary school students who read below grade level. The company that developed this program supplied materials and teacher training for a large-scale test involving nearly 8500 children in several different school districts. Statistical analysis of the results showed that the percentage of students who did not meet the grade-level goal was reduced from 15.9% to 15.1%. The hypothesis that the new reading program produced no improvement was rejected with a P-value of 0.023.
a) Explain what the P-value means in this context.
b) Even though this reading method has been shown to be significantly better, why might you not recommend that your local school adopt it?
Answer:
The solution to the given points can be defined as follows:
Step-by-step explanation:
In point a:
There is still a 2.3% chance which 15.1% of learners who also don't achieve a level by naturally-excluding specimens only will see if 15.9% is the population means value.
In point b:
Throughout the old system, 1352 learners must not read in classes, but 1284 should not write throughout academic performance throughout the new curriculum. A reduction, as well as the significance of such a decrease, would depend mostly on the cost of switching to the new initiative.
a. The explanation of the p-value should be explained below.
b. The suggestion that should not be considered is also explained below.
P-value and the suggestion not considered:a. Since there is a still 2.3% chance that 15.1% of learners should not accomplish the level via naturally-excluding specimens only would watch in the case when 15.9% should represent the mean value of the population.
b. If we considered the old system, so 1352 learners should not read the class however, 1284 should not write the academic performance. So there is the reduction that based on the switching cost
