Answer:
BC =26
Step-by-step explanation:
AB is to be doubled in order to equal AC. 6x-2 = 8x-20. X=9
Since B is the midpoint BC=AB, so both sides would be equal to 26
Answer:
-1.00
Step-by-step explanation:
Given that a publisher reports that 45% of their readers own a laptop. A marketing executive wants to test the claim that the percentage is actually different from the reported percentage.
Sample size n =190
Sample proportion p = 0.41
(Two tailed test )
Assuming H0 to be true
std error =
p difference = -0.04
Test statistic = p differencce/std error
= -1
Hence test statistic is -1.00
Answer:
add x
Step-by-step explanation:
1)sx*tx
2)sx+tx
3)s-t
Answer:
For this case we can model the problem as a rectangle triangle.
We know:
Length of the hypotenuse
Angle between the base of the triangle and the hypotenuse.
We want to know:
Length of the base.
For this we use the following trigonometric relationship:
cos (15) = \frac{x}{500}cos(15)=500x
Clearing x we have:
x = 500 * cos (15) x = 482.96x=500∗cos(15)x=482.96
Rounding to the nearest tenth of a meter:
x = 483.0 mx=483.0m
Answer:
The horizontal distance she has covered is:
x = 483.0 mx=483.0m
Answer:
40.4
Step-by-step explanation:
We don't have access to your drawing tools, so we have used our own. The attachment shows the triangle and the angle.
∠ABC ≈ 40.4°
