Answer:
317.6 feet
Step-by-step explanation:
the length of the diagonal can be determined using Pythagoras theorem
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
280² + 150²
= 78,400 + 22,500
= 100,900
take the square root of 100,900
= 317.648 feet
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
317.6 to the nearest tenth
Answer:
Step-by-step explanation:
Point M is the midpoint of XY since it is a bisector. Thus, XM = MY.
Subtract 1 from both sides:
Subtract 8x from both sides:
Divide both sides by -5:
Yes, that may be possible.

Answer:
For each of the sample sizes given, for the population to be regarded as effectively infinite, student population has to be more than
a) 240 students.
b) 1,040 students.
c) 1,920 students.
Step-by-step explanation:
A population may be treated as infinite when the population size, N, is at least 20 times the sample size, n.
Mathematically,
(N/n) > 20
N > 20n
(a) A sample of 24 students.
If sample size = n = 24
For the population size to be effectively infinite,
N > 20n
N > 20×24
N > 480 students
(b) A sample of 52 students.
If sample size = n = 52
For the population size to be effectively infinite,
N > 20n
N > 20×52
N > 1,040 students
(c) A sample of 96 students.
If sample size = n = 96
For the population size to be effectively infinite,
N > 20n
N > 20×96
N > 1,920 students
Hope this Helps!!!
Answer:
s = a + b + c/2
= 6 + 8 + 10/2
= 12 inches
Area = √s(s-a)(s-b)(s-c)
= √12×(12 - 6)×(12 - 8)×(12 - 10)
= 24 inches^2
Step-by-step explanation:
Sorry if this isn't right, you might just have to apply regular Pythagorean theorem.
