I got 0.3125 (i don’t know if that’s correct, because the question was hard for me to understand)
Answer:
THIS IS ANSWER STEP BY STEP:
The arcs in the corners of the triangle mean that all 3 angles are the same.
Because the 3 angles are all the same this means that all 3 sides are also the same.
To solve for X, we can set 2 of the equations to equal each other and solve for x:
6x-3 = 3x +6
Add 3 to each side:
6x = 3x +9
Subtract 3x from each side:
3x = 9
Divide both sides by 3:
x = 9/3
X = 3
And if you replace x with 3 in each of the equations, they all equal 15.
Answer:
Tstatistic = - 3.068
Step-by-step explanation:
Given the data: 9.7% 7.4% 5.9% 7.7% 7.5% 8.9%
Mean titanium > 9.5%
Test statistic :
(m - μ) / (s/√n)
From the data: obtain the sample mean and standard deviation
From the data given ;
Calculate the same mean and standard deviation :
Using calculator :
Sample mean (m) = ΣX / n
Sample size (n) = 6
m = 47.1 / 6 = 7.85
Standard deviation (s) :
Using calculator = 1.317
Hence,
(m - μ) / (s/√n)
Tstatistic = (7.85 - 9.5) / (1.317/√6)
Tstatistic = - 1.65 / 0.5376629
Tstatistic = - 3.068
Answer:
x =5
Step-by-step explanation:
Tangents from same external point have equal length.
KJ = LJ
4x - 1 = 2x + 9
Add 1 to both sides
4x = 2x + 9 + 1
4x = 2x + 10
Subtract '2x' from both side
4x - 2x = 10
2x= 10
Divide both sides by 2
x = 10/2
x = 5
