Answer: E is the answer
Step-by-step explanation:
The population sample that does not produce a biased result is when he asks every fifth student arriving at school. The correct option is E.
What is a survey?Surveys can be used to determine how representative each person's opinions and experiences are.
When conducted properly, surveys offer precise data about people's beliefs and actions that can be utilized to inform significant decisions.
A huge population's characteristics can be described through surveys. No other research methodology can offer such a wide range of capabilities.
This guarantees a more accurate sample to collect focused results from which to draw conclusions and make significant judgments.
Survey bias is when a question is worded or presented in a way that encourages individuals to select one response over another.
The same holds true if your queries are challenging for customers to comprehend and honestly answer.
As, when he asks every fifth student arriving at school, it can lead to an unbiased result.
Thus, the correct option is E.

if you roll a dice one time what is the probability for it not to land on an odd number
Answer:
3/6
Step-by-step explanation:
Simple-
One di has 6 sides.
Three sides are even numbers
We are looking for the probability of not having and odd number chosen
It would be 3/6 because there are 3 even numbers and 3 odd numbers, and we are using even numbers because we need to know the probability of not landing on an odd number.

Answer:
23) x=20; y=10√3
24) x=4√2; y=8
25) x=12; y=3+6√3
Step-by-step explanation:
Recognize that all of the triangles involved here are one of the two "special" triangles. By previous use of the Pythagorean theorem, or your familiarity with the trig functions of the "special" angles 30°, 45°, 60°, you know the following side ratios:
45°-45°-90° triangle: 1 : 1 : √2
30°-60°-90° triangle: 1 : √3 : 2
Using these ratios, you can solve these figures "by inspection."
__
23) x = 2((10√2)/√2) = 20
y = √3((10√2)/√2) = 10√3
__
24) x = 4√2
y = (4√2)√2 = 8
__
25) x = 6·2 = 12
y = 3 +6√3 . . . . . 3 units more than the longer leg of the 6 : 6√3 : 12 triangle

The correct option is A.
What is length of line segment?The distance between any two points is the length of the line segment joining the points.
The formula for the distance, D, between two points whose coordinates are (x₁, y₁) and (x₂, y₂)
D = √((x2 – x1)² + (y2 – y1)²)
This is called the Distance Formula.
Given,
Coordinates of points Q (8, 2) and R (5, 7)
Length of QR = Distance between point Q and point R.
D = √((x2 – x1)² + (y2 – y1)²)
D = √((5 - 8)² + (7 - 2)²)
D = √(-3² + 5²)
D = √9 + 25
D = √34
D = 5.83 units
Length of QR rounded to one decimal = 5.8 unit
Hence, 5.8 unit is closest to the length of QR = 5.83units

deviation is 5 minutes, 95% of the employees will have a travel time within
which range?
A. 17.25 minutes to 26.75 minutes
B. 12 minutes to 32 minutes
C. 7 minutes to 37 minutes
D. 17 minutes to 27 minutes
Answer:
12 minutes to 32 minutes
Step-by-step explanation:
just took exam
If the mean time is 22 minutes and the standard deviation is 5 minutes, 95% of the employees will have a travel time within 12 minutes and 32 minutes.
What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
We know that the mean travel time is 22 minutes (µ = 22) and the standard deviation is 5 minutes (σ = 5).
Using the empirical rule, we know that 95% of the data will fall within 2 standard deviations of the mean.
Therefore, we need to find the interval that is 2 standard deviations away from the mean in both directions.
The lower end of the range would be:
µ - 2σ = 22 - 2(5) = 12 minutes
The upper end of the range would be:
µ + 2σ = 22 + 2(5) = 32 minutes
Therefore, 95% of the employees will have a travel time between 12 minutes and 32 minutes.

Huixian's grandparents own a farm with m goats and
n chickens. She counted that the animals have a
total of 52 heads and 140 legs. How many goats and
how many chickens are there on the farm?
Hint: A goat has 4 legs and a chicken has 2 legs.
Step-by-step explanation:
2(heads) + 2(goats) = 140
Heads are given, so we get:
2(52) + 2(goats) = 140
104 + 2(goats) = 140
2(goats) = 36
goats = 18
Since we know the number of goats, we know the number of chickens.
34Chickens and 18 goats.

Which is better value for money: 2 pizzas for
£12 or 4 pizzas for £28?
For the first one, each pizza is $6
For the second one, each pizza is $7
The first one is the answer
Answer:
2 pizzas for £12.
Step-by-step explanation:
[tex]\frac{2}{12}: \frac{1}{y}[/tex]
y · 2 = 12 · 1
2y = 12
2y ÷ 2 = 12 ÷ 2
y = 6
£6 for 1 at the price of 2 for £12.
[tex]\frac{4}{28}: \frac{1}{y}[/tex]
y · 4 = 28 · 1
4y = 28
4y ÷ 4 = 28 ÷ 4
y = 7
£7 for 1 at the price of 4 for £28.
The exponential equation 34 = 81 can be written as logarithmic equation
in the form:
The exponential equation 3⁴ = 81 can be written as a logarithmic equation in the form will be 4 = ㏒₃ 81. Then the correct option is D.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The exponential equation is given below.
3⁴ = 81
Take log on both sides with base 3, then we have
㏒₃ 3⁴ = ㏒₃ 81
4㏒₃ 3 = ㏒₃ 81
4 = ㏒₃ 81
The exponential equation 3⁴ = 81 can be written as a logarithmic equation in the form will be 4 = ㏒₃ 81. Then the correct option is D.

180°
→ Form an equation
90 + 4x - 10 + x = 180

Step-by-step explanation:
The Pythagorean Theorem states that a^2 + b^2 = c^2, in which c is the hypotenuse (in this case, PQ and RS).
1: 105^2 + 208^2 = 54289, square root of 54289 = 233
2: Since the area of the triangle makes up half of the rectangle, multiply the area by 2 to get 466
3: 120^2 + 210^2 = 58500, square root of 58500 is 241.87
