Answer:
x = 10 ft
Step-by-step explanation:
By Pythogorus theorem,
x^2 = 8^2 + 6^2
x^2 = 64 + 36
x^2 = 100
x = sqrt(100)
x = 10 ft
The second option: The student should have distributed and written -2x+5, not -2x-5.
That’s because the two negatives make a positive when multiplying/distributing.
Answer:
A) Construct a two-sample z -interval for the difference between population proportions.
Answer:x = 60
Step-by-step explanation:
The given triangle is an equilateral triangle. This is so because all the angles are equal. This also means that all the sides are equal.
The sum of the angles on a straight line is 180 degrees. Assuming each angle of the equilateral triangle is y degrees, it means that
y + 2x = 180
y = 180 - 2x
The sum of the angles in a triangle is 180 degrees. It means that
y + y + y = 3y = 180
This means that
3(180 - 2x) = 180
540 - 6x = 180
6x = 540 - 180 = 360
x = 360/60 = 60
The IQR is q1-q3! Put the numbers in order, least to greatest. then find the quartiles.
