how do you write an equation in slope-intercept form for the line with a slope 5 and y-intercept -5
Answer:
y=5x-5.
Step-by-step explanation:
slope-intercept form of a line is y = mx+b, where m is the slope and b is the y intercept. Simply plug in the numbers you get.
Thus, we get y = 5x-5.
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.

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

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

(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.

How do you round to the nearest unit?
Help me here plz thanks
Answer:
Rounding to the nearest unit means to find the nearest integer to a given number. Before you remove the decimal take the first number of the decimal (45.68) Take 6 (The number that comes first after the decimal).
If the number is 5 and less then convert the number to a lower number.
If the number is more than 5 then convert the number to a higher number.
Ex: 34.41. The answer would be 33 because 4 is less than 5.
Ex: 34.61. The answer would be 35 because 6 is more than 5.
I hope this helps :)
Answer:
Bonjour CocinelleStep-by-step explanation:
Rounding to the nearest unit means to find the nearest integer to a given number.
Basically, you have to get rid of the decimal part, if any.
As an immediate corollary, you have that if a number x
is already an integer, then there's no point in rounding it, since the result would be x itself.
Now, let's assume that our number actually has a decimal part, for example
4.687
It might help you to think of this number as
4+0.687
to clearly see that 4.687 lies between
4 and 5
, since it is something (0.687) more than 4 , but still not 5
So, the question is: is our number closer to
4 or to 5? Which, in turn, means to ask: the decimal part that we've added,
0.687 , is nearest to 0 or 1 ?
If it is nearest to 0 , it means that our number is more than 4 , but still nearer to
4
than it is to 5, otherwise it is "far enough" from 4 to be nearer to 5
Since halfway between 0 and 1 is 0.5 , and our decimal part is 0.687>0.5 , we can say that 4.687 is rounded to
5.

Write your answer in feet and inches. Use a number less than 12 for inches.
