class frequency midpoint r.frequency c. frequency
The class with the greatest frequency is the class "15.2 - 19" with a frequency of 7. The class with the least frequency is the class "0 - 3.8" with a frequency of 2.
To construct a frequency distribution with 5 classes for the given data representing time spent reading a political blog in a day, we need to determine the class intervals and calculate the frequency, midpoint, relative frequency, and cumulative frequency.
First, we find the range of the data:
Range = Maximum value - Minimum value
Range = 19 - 0
Range = 19
To determine the class width, we divide the range by the desired number of classes:
Class width = Range / Number of classes
Class width = 19 / 5
Class width ≈ 3.8
Now, we can construct the frequency distribution table:
Class Frequency Midpoint R. Frequency C. Frequency
0 - 3.8 2 1.9 2/20 = 0.1 2
3.8 - 7.6 4 5.7 4/20 = 0.2 6
7.6 - 11.4 4 9.5 4/20 = 0.2 10
11.4 - 15.2 3 13.3 3/20 = 0.15 13
15.2 - 19 7 17.1 7/20 = 0.35 20
By organizing the data into classes and analyzing the frequencies, we can gain insights into the distribution of reading time and identify the most and least common time intervals spent on reading the political blog.

In one school district, there are 123 elementary school (K-5) teachers, of which 20 are male (or male-identifying). In a neighboring school district, there are 142 elementary teachers, of which 26 are male. A policy researcher would like to calculate the 90% confidence interval for the difference in proportions of male teachers. To keep the signs consistent for this problem, we will calculate all differences as p 1 − p 2 . That is, start with the percentage from the first school district and then subtract the percentage from the second district. Failing to do so may end up with “correct” answers being marked as wrong. Point estimate for the percentage males in the first district: ˆ p 1 = Point estimate for the percentage males in the second district: ˆ p 2 = Point estimate for the difference in percentages between the two districts: ˆ p 1 − ˆ p 2 = Estimate of the standard error for this sampling distribution (distribution of differences): √ ˆ p 1 ( 1 − ˆ p 1 ) n 1 + ˆ p 2 ( 1 − ˆ p 2 ) n 2 = Critical value for the 90% confidence level: z c.v. = 90% margin of error: M.E. = 90% confidence interval: ≤ p 1 − p 2 ≤
With a margin of error of 0.0791, the 90% confidence interval for the difference in the percentages of male instructors in the two school districts is -0.0996 p1 - p2 0.0581.
What's the 95% point estimate?The sample percentage serves as the point estimate for the population proportion, and the margin of error is calculated as the product of the point estimate's standard error and the Z value for the desired degree of confidence (e.g., Z=1.96 for 95% confidence).
A rough estimate of the male population in the first district is as follows: 20/123 = 0.1626
Point estimate for the second district's male population: 26/142 = 0.1831
A rough estimate of the percentage difference between the two districts is as follows: 0.1626 - 0.1831 = -0.0205
Calculation of this sample distribution's standard error of the distribution
√ [(0.1626)(1-0.1626)/123 + (0.1831)(1-0.1831)/142] = 0.0481
Critical value for the 90% confidence level: z_c.v. = 1.645 (from standard normal table)
Margin of error: M.E. = 1.645 * 0.0481 = 0.0791
90% confidence interval: -0.0205 - 0.0791 ≤ p1 - p2 ≤ -0.0205 + 0.0791
-0.0996 ≤ p1 - p2 ≤ 0.0581

What happens to the apparent brightness of a star as you get closer to it? Science
A It gets brighter.
B It gets dimmer.
C It gets larger.
D It gets smaller.
Answer:
C
Explanation:
A star does not necessarily get brighter or dimmer when you get closer to it. The apparent brightness of a star is determined by both its intrinsic luminosity (how much energy it emits) and its distance from Earth. If you move closer to a star, the distance between you and the star decreases, so the apparent size of the star increases. However, if the intrinsic luminosity remains the same, the net effect on brightness will be negligible. On the other hand, some stars may appear to change in brightness due to atmospheric effects, such as scintillation and atmospheric extinction, which can affect the amount of light that reaches Earth and how it is perceived.

In a management trainee program, 80% of the trainees are female, while 20% are male. Ninety percent of the females attended college; 78% of the males attended college. A management trainee is selected at random. What is the probability that the person selected is a female who did not attend college?
Answer:
Explanation:
Let's first find the proportion of females who attended college:
80% of trainees are female
90% of females attended college
So the proportion of female trainees who attended college is 0.8 x 0.9 = 0.72.
To find the proportion of female trainees who did not attend college, we can subtract this from 1:
Proportion of female trainees who did not attend college = 1 - 0.72 = 0.28
Therefore, the probability that a person selected at random is a female trainee who did not attend college is 0.28 or 28%.

Which equations represent circles that have a diameter of 12 units and a center that lies on the y-axis? Select two options.
x2 + (y – 3)2 = 36
x2 + (y – 5)2 = 6
(x – 4)² + y² = 36
(x + 6)² + y² = 144
x2 + (y + 8)2 = 36
Answer:
x² + (y - 3)² = 36, and x² + (y +8)² = 36
Explanation:
equation of a circle is (x - a)² + (y - b)² = r²
where a is the x-coordinate in centre of circle, b is is y-coordinate in centre of circle and r is the radius of the circle (half of diameter).
if our circle lies on the y-axis then its x-coordinate must be 0.
just x², no ( x - a)².
if its diameter is 12, then its radius is 6.
in formula, r² must me 6² = 36.
only the first and last equations in the questions match this criteria.
that is, x² + (y - 3)² = 36, and x² + (y +8)² = 36.
Zora wants to dissolve a solute in a solvent quickly. Which best describes what she should do?
decrease the pressure
decrease the surface area
shake it repeatedly
place in a refrigerator
To dissolve a solute in a solvent quickly, Zora should shake it repeatedly.
Which best describes what she should do?Shaking the mixture or stirring it vigorously promotes the interaction between the solute and solvent molecules, increasing their chances of coming into contact and facilitating the dissolution process. This agitation helps in breaking down the solute particles and dispersing them evenly throughout the solvent, thereby accelerating the dissolution rate.
Decreasing the pressure or decreasing the surface area would not have a significant impact on the dissolution process. Pressure and surface area primarily affect the rate of dissolution for gases or solid particles exposed to the solvent, but they are not applicable in all scenarios.
Placing the mixture in a refrigerator would slow down the dissolution process rather than speed it up. Lowering the temperature decreases the kinetic energy of the molecules, reducing their movement and the overall rate of dissolution.

Add rational expressions with unlike denominators
x-5/4x^2-25x-21 + 4x^2+15x+9
Answer:
Explanation:
To add two rational expressions with unlike denominators, you need to first find a common denominator and then add the numerators.
The common denominator for the two given rational expressions is 4x^2 + 25x - 21.
The first expression can be written as (x - 5)/(4x^2 + 25x - 21), and the second expression as (4x^2 + 15x + 9)/(4x^2 + 25x - 21).
To find the numerators for these rational expressions, we multiply each fraction by the common denominator. We get:
x - 5 = (x - 5) * (4x^2 + 25x - 21) / (4x^2 + 25x - 21) = 4x^3 + 20x^2 - 4x - 105
and
4x^2 + 15x + 9 = (4x^2 + 15x + 9) * (4x^2 + 25x - 21) / (4x^2 + 25x - 21) = 4x^3 + 34x^2 + 6x + 189.
Now that we have the numerators, we can add the two rational expressions to get the result:
x - 5/4x^2 - 25x - 21 + 4x^2 + 15x + 9 = 4x^3 + 54x^2 + 2x + 84 / (4x^2 + 25x - 21)

How many liters each of a 50% acid solution and a 75% acid solution must be used to produce 90 liters of a 60% acid solution? (Round to two decimal places if necessary.)
The numbers of liters that is needed is 40 liters of 25% solution and 40 liters of 65% solution.
What is the litters about?Note that:
We take x = volume of 25% solution.
We take y = volume of 65% solution.
So, Equation of total volume:
x + y = 80
Hence the equation of amount of acid:
0.25x + 0.65y = 0.45(80)
0.25x + 0.65y = 36
Solve x + y = 80 for x.
x = 80 - y
Then Substitute into the second equation.
0.25(80 - y) + 0.65y = 36
20 - 0.25y + 0.65y = 36
0.4y = 16
y = 40
x + y = 80
x + 40 = 80
x = 40
Therefore, The numbers of liters that is needed is 40 liters of 25% solution and 40 liters of 65% solution.
