The coordinates of the endpoints of QR are
Q (8, 2) and R (5, 7) ).
Which measurement is closest to the length of QR
in units?
A 5.8 units
B 5 units
C 4 units
D 3.9 units
Answers
Answer: I just did the test so the answer is A. 5.8 units
Step-by-step explanation: hope this help thx for the points :D
Length of QR in units = 5.83 units, which is closest to 5.8 units.
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

A carpenter is constructing a staircase in a house. The distance from the first floor to the basement is 9.2 feet. The staircase will be 13.3 feet long. What angle do the stairs make with the basement floor?
Answers
Answer:
43.77°
Step-by-step explanation:
The height, h = first floor to basement = 9.2 feets
Length of staircase = hypotenus = 13.3 feets
Angle stacase makes with basement floor, θ
Using trigonometry :
Sinθ = opposite / hypotenus
Opposite = height = 9.2 feets
Sinθ = 9.2 / 13.3
Sinθ = 0.6917293
θ = sin^-1(0.6917293)
θ = 43.77°

Hi there!
A function is a set of ordered pairs that do not have same x-values.
In a set of ordered pairs, If two or more ordered pairs have same x-values, they are not considered as a function but rather a relation instead.
From the question above, you notice that two of the choices have same x-values and others don't have.
The relations that are not functions are the second choice and fourth choice because two ordered pairs have same x-values.
Any questions can be asked through comment.
Furthermore, a function is also a relation but a relation isn't always a function.
Hope this helps, and Happy Learning! :)
Based on historical data, your manager believes that 43% of the company's orders come from first-time customers. A random sample of 243 orders will be used to estimate the proportion of first-time-customers. What is the probability that the sample proportion is between 0.2 and 0.39?
Answers
Answer:
Following are the solution to the question:
Step-by-step explanation:
[tex]p = 0.43\\\\n = 243\\\\\sigma =\sqrt{\frac{p(1-p)}{n}}=\sqrt{\frac{0.43 (1 -0.43)}{243}}=0.0013[/tex]
z-score for [tex]\hat{p}=0.2[/tex] will be:
z score for will be:
[tex]z=\frac{\hat{p}-p}{\sigma}=\frac{0.39 - 0.43}{0.0013}=-30.76[/tex]
[tex]P(0.2 <\hat{p}< 0.39) = P(-176.92 < z < -30.76)[/tex] using excel method to calculate the value.
