Since AB is twice the size of XZ (according to geometry) then you multiply XZ by 2. Then you make that value = to AB and solve
So the answer is B.
Answer:
45° + x° = 90°
Step-by-step explanation:
Two angles are complementary if the sum of the angles is equal to 90 degrees. we can also said that if we had two angles A and B and these angles are complementary, the equation that represent this situation is:
A + B = 90°
Then, if a 45°angle is complementary to an angle measures ×°, the equation that represents this situation is:
45° + x° = 90°
Therefore, solving for x°, we get:
45° + x° - 45° = 90° - 45°
x° = 45°
it means that a 45°angle is complementary to an angle measures 45°

Answer:
The 95% of confidence intervals
(2.84 ,2.99)
Step-by-step explanation:
A random sample of 20 accounting students results in a mean of 2.92 and a standard deviation of 0.16
given small sample size n =20
sample mean x⁻ =2.92
sample standard deviation 'S' =0.16
level of significance ∝ = 0.95
The 95% of confidence intervals
the degrees of freedom γ=n-1 =20-1=19
t-table 2.093


(2.92-0.0748,2.92+0.0748)
(2.84 ,2.99)
Therefore the 95% of confidence intervals
(2.84 ,2.99)
The x-intercepts<span> are where the graph crosses the x-axis, and the y-</span>intercepts<span> are where the graph crosses the y-axis. We find these intercepts when we set one variable to zero. For instance,
</span><span>
y = x^2-10x+25
y-intercept : y = </span>0^2-10(0) +25
<span> y = 25
x-intercept: 0 = </span>x^2-10x+25
0 = (x - 5) (x - 5)
x = 5
