y=b slope= 4/1
Step-by-step explanation:
Answer:
value of x = 20°
Step-by-step explanation:
the given pair of angles are pair of co - interior angles
So, their sum = 180°
=》3x - 10° + 5x + 30° = 180°
=》8x + 20° = 180°
=》8x = 180° - 20°
=》8x = 160°
=》x = 20°
Answer: the t-test statistic is - 1.77
Step-by-step explanation:
For the null hypothesis,
H 0: μ = 2600
For the alternative hypothesis,
H a: μ ≠ 2600
This is a two tailed test
Since no population standard deviation is given, the distribution is a student's t.
Since n = 50,
Degrees of freedom, df = n - 1 = 50 - 1 = 49
t = (x - µ)/(s/√n)
Where
x = sample mean = $2450
µ = population mean = $2600
s = samples standard deviation = $600
Therefore,
t = (2450 - 2600)/(600/√50) = - 1.77
The perimeter of the triangle is : 12.6.
This result is obtain by the use of triangle perimeter formula :

Where : a is the distance between the points A and B
b is the distance between the points B and C
c is the distance between the points C and A
