Question:
Convert the angle θ=260° to radians.
Express your answer exactly.
θ = ___ radians
Answer:
260° = 13π/9 or 4.54 rad
Step-by-step explanation:
Given
θ=260°
Required
Convert from degree to radians
To convert an angle in degrees to radians, we simply follow the steps below.
1° = 1 * π/180 rad
Replace the 1° with x
So,
x° = x * π/180 rad.
Now, we assume that x = 260
This means that we substitute 260 for x. This gives
260° = 260 * π/180
260° = 260π/180
Divide numerator and denominator by 20
260° = 13π/9
We can leave the answer in this form or solve further.
Take π as 22/7. This gives
260° = 13/9 * 22/7
260° = 286/63
260° = 4.5396825397
260° = 4.54 rad (Approximated)
Answer:
Mean of the population having 6"-9" Hatching =38
Standard Deviation =4
Step-by-step explanation:
Confidence interval of 95% means that 95% of data lie within two standard deviations.
That is data values lie between 38-2×4 to 38 +2×4.
⇒Which is 38-8 to 38+8.
⇒30 to 46.
it is also given that margin of error is 2.5%.
So, the data value will lie between
Mean of beginning value to extreme value of 95% confidence level
So, Sample mean of this observation having 2.5% margin of error = 38
Option D:→ 38
Answer:
B) y = -3x+2
Step-by-step explanation:
plug (2,-4) and -3 into y = mx + b to find 'b'
-4 = -3(2) + b
b = -4+6 = 2
Since the height is different on both ends, we can assume that the wall is a trapezoid. Knowing that, we can replace the measures we know in the formula and our onky variable is the length of the wall - we only need to isolate it.
A= ((b+B)h)/2
26.4=((2+2.4)h)/2
52.8=4.4h
h=12
