Answer:
104°
Step-by-step explanation:
In order to find out the value of x we must figure out the other angles. The line on the extended side adds up to 180 degrees. Use that information to find the other angle.
180 - 128 = 52
The one angle is 52. Then, we know that a triangles angles always add up to 180 degrees as well. So create an equation:
180 - 52 - 24 = 104
For this case we observe that we have a triangular prism.
The triangular prism has two triangles.
A triangle for the base of the prism.
A triangle for the top of the prism.
The lateral faces of the prism are rectangular.
Answer:
Are needed:
2 triangles
The cost of the burger is $6
Answer:
see explanation
Step-by-step explanation:
since the dilatation is centred at the origin , then multiply each of the coordinates of A, B, C by the scale factor 2, that is
A' = (2(- 2), 2(- 2) ) = A'(- 4, - 4 )
B' = (2(1), 2(- 1) ) = B'(2, - 2 )
C' = (2(2), 2(0) ) = C'(4, 0 )
Answer:
The minimum sample size to have this margin of error is n = 897.
Step-by-step explanation:
We have to estimate a parameter with a confidence interval. The confidence level is 95% and the margin of error is 0.5 days.
The population standard deviation is 7.64 days.
The critical value of z for a 95% confidence interval is z=1.96.
We have to calculate the minimum sample size.
To do that, we use the margin of error formula in function of n:
The minimum sample size to have this margin of error is n = 897.
