Answer:
Step-by-step explanation:
we know that
---->
see the attached figure to better understand the problem
Triangles ABD and BCD are similar by AA Similarity Theorem
Remember that
If two figures are similar, then the ratio of its corresponding sides is proportional
so
substitute the given values
simplify
Answer: 1.) 57342
Tens = 57340
Hundreds = 57300
2.) 76564
Tens = 76560
Hundreds = 765600
3.) 95634
Tens = 95630
Hundreds = 95600
4.) 85756
Tens = 85760
Hundreds = 85800
5.) 63526
Tens = 63530
Hundreds = 63500
Step-by-step explanation:
B) If the line is parallel, that means the slope is the same.
The slope for the original line is
=
.
The second form of coral line would be y = -1/4x + (any number). You could use
y = -1/4x + 3.c) Solve 12x = 24 + 3y for y.
3y = 12x - 24
y = 4x - 8
Perpendicular lines have negative reciprocal slopes... the negative reciprocal for -1/4 is 4. So
yes, the third coral structure is perpendicular to the first coral.
Answer:
I believe it is 6
Step-by-step explanation:
If you think about it the opposite of 6 is -6
and the only one that is -6 is c
because it is in absolute value {6}
will be 6 but there is a negative sign which then you just bring that down and you would get -6
Answer:
The sample size must be atleast 3600
Step-by-step explanation:
We are given the following in the question:
The scores of individual students on the American College Testing (ACT) Program is a bell shaped distribution that is a normal distribution.
Population standard deviation = 6.0
We want that the sample standard deviation should not be more than 0.1.
Thus, the standard error should not be more than 0.1.
Standard error =
Putting values, we get,
Thus, the sample size must be atleast 3600
