Answer:
42.02 ft
Step-by-step explanation:
60 : 360 = 44 : x
x = 264 ft (length of the circumference)
C = 2 * radius * pi
radius = C / 2 * pi
Radius = 264 / 2 * pi = 42,016905 ft
Answer: 0.50 of 1.
Step-by-step explanation: Because 0.27 is smaller and is in a larger number, it is not 1 half, while 0.50 of 1 is 1 half. Hope this helps!
Answer:
B: All four triangles are congruent.
C: All four triangles are right-angled.
E; Area of rhombus = 4 times the area of one triangle.
Step-by-step explanation:
A rhombus is a quadrilateral with equal length of sides. It stands on one of its edges, and a simple example is the shape of a diamond. It has two diagonals which bisect the angles of the rhombus.
When a rhombus is cut along its diagonals, the following properties of the shape formed can be observed:
B: All four triangles are congruent.
C: All four triangles are right-angled.
E; Area of rhombus = 4 times the area of one triangle.
Answer:
8x⁵y - 6x⁴y²
Step-by-step explanation:
(2x³)(4x²y - 3xy²)
= 2x³ * 4x²y + 2x³ * -3xy²
= 8x⁵y - 6x⁴y²
Answer:
95% confidence interval: (-0.0586,0.0106)
Step-by-step explanation:
We are given the following in the question:
In 2015, 420 out of 1090 people surveyed said it was serious.
In 2016, 1063 out of 2,600 people surveyed said it is serious.
a) Confidence Interval:
Putting the values, we get:
b) Since confidence interval contains 0 , hence there is no significant difference at a = 0.05
