In a survey of 720 human resource professionals, each was asked about the importance of the education of a job applicant. The survey subjects were randomly selected by pollsters from a reputable market research firm.
It seems to be reasonable so because survey data is unbiased.
What is defined as the unbiased survey data?An unbiased sample is one in which every individual or element in the population does have an equal chance of being chosen.
A sample assessment of a population parameter for whom sampling distribution does have a mean equal to the parameter of been estimated is an unbiased statistic. Some traditional statistics provide unbiased estimates of their associated parameters, while others do not. The sample mean is the most basic example of an unbiased statistic. The sample mean is normally distributed with a mean equal to the population mean under the usual assumptions of population normality and simple random sampling with a mean equal to the population mean and a standard deviation equal to the population variance divided by the square root of the sample size.As, for the given question, the 720 human resource professionals survey is done considering each individual equal weight age for all.
A population proportion is also a unbiased estimate of a sample proportion.

The perimeter of the triangle shown is 89 meters. Find the length of each side.
Greetings from Brasil...
The perimeter is the sum of all sides of the triangle. In this case
P = (2X) + (X) + (4X - 9)
as P = 89
89 = (2X) + (X) + (4X - 9)
89 = 7X - 9
7X = 98
X = 98/7
X = 14X:
X meters = X = 14
---------------------------------------------
2X:
2X meters = 2 · X = 2 · 14 = 28
---------------------------------------------
(4X - 9):
(4X - 9) meters = (4 · X - 9) = (4 · 14 - 9) = (56 - 9) = 47

Answer:
The number of yards of ribbon that Diane buy in total from the prepaid debit card with $25 on it is 0.18 yards.
Step-by-step explanation:
It is given that, Diane got a prepaid debit card with $25 on it. For her first purchase with the card, she bought some bulk ribbon at a craft store. The price of the ribbon was 12 cents per yard.
Now, if after that purchase there was $22.84 left on the card, let's calculate how many yards of ribbon did Diane buy in total and for that we need to;
Furthermore, based on the given conditions, we will be formulating the following;
=> (25-22.84) / 12
=> 2.16/12
=> 216/100 × 1/12
=> 9/25 × 1/2
=> 9 / (25×2)
=> 9/50
=> 0.18 yards
Therefore, the number of yards of ribbon that Diane buy in total from the prepaid debit card with $25 on it is 0.18 yards.

The inequality solves to [tex]\text{x} \le 36[/tex]
=====================================================
Explanation:
The goal is to solve for x.
Multiply both sides by 2 to go from
[tex]\frac{1}{2}\text{x} \le 18[/tex]
to
[tex]\text{x} \le 36[/tex]
The inequality sign does not flip. It would only do so if you multiplied or divided both sides by a negative number.
The graph will have a closed filled in circle at 36, with shading to the left. This is to visually show the set of all x values that are 36 or smaller. The endpoint 36 is included in the solution set (an open hole would be used if you wanted to exclude it from the solution).

The perimeter of a rectangular window is 324 cm .
If the width of the window is 73 cm , what is its length?
Answer:
The length is 89 cm============================
Perimeter equationP = 2(l + w), where
P- perimeter, l- length, w- widthGivenP = 324 cm,w = 73 cmFind the value of l:
324 = 2( l + 73)l + 73 = 324/2l + 73 = 162l = 162 - 73l = 89Answer:
L = 89 cm
Step-by-step explanation:
Formula we use,
→ P = 2(L + W)
Then the value of its length is,
→ P = 2(L + W)
→ 324 = 2(L + 73)
→ 324 = 2L + 146
→ 2L = 324 - 146
→ L = 178/2
→ [ L = 89 cm ]
Hence, the length is 89 cm.

what is the complement of 14 17'
The complement of the angle 14° 17' would be; 75° 43'
What is the Complement of the Angle?We want to find the complement of the angle 14° 17'
The complement of 14° is the angle that when added to 14° forms a right angle (90° ).
Now, when an apostrophe is found in the word angles, it means 'angular minutes, while " denotes angular seconds. For instance, "75degree 20′ 39" means "75 degrees, 20 minutes, and 39 seconds."
Thus, 14° 17' means 14 degrees, 17 minutes.
Now, 17 minutes when converted to degree is;
17/60 degrees = 0.283. Thus; 14° 17' = 14.283

(−4, 0)
The turning point is the point where the function changes its slope for the given mode function f(x)=|x|+4 the turning point is at (0,4) so option (B) will be correct.
What is a graph?A graph is a diametrical representation of any function between the dependent and independent variables.
The graph is easy to understand behavior of the graph.
Given the mode function,
f(x)=|x|+4
For x < 0 the function f(x) will be
f(x) = -x + 4
For x > 0 the function f(x) will be
f(x) = x + 4
Now,
Slope at x < 0 → f'(x) = -1
Slope at x > 0 → f'(x) = +1
Since the slope is changing at x = 0 there fore x = 0 will be the turning point of the graph.
Hence "The turning point of the given mode function f(x)=|x|+4 will be at x = 0".
