Answer:
around 90 cm because that measure is equal to 180 you divide into 2 so the answer is 90
each coind has a 1/2 probability of landing on heads
3 coins would be 1/2 x 1/2 x 1/2 = 1/8 probability
Answer:
they bisect each other
Step-by-step explanation:
<em>The diagonals of a parallelogram bisect each other</em>.
__
If they are the same length, the parallelogram is a rectangle. If they cross at right angles, it is a rhombus.
Answer:
A. By SAS only
Step-by-step explanation:
Side Side Side postulate (SSS) states that if three sides of one triangle are congruent to three sides of another triangle, then these two triangles are congruent.
Side Angle Side postulate (SAS) states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then these two triangles are congruent.
In triangles ABC and AED:
- sides ACand AD are congruent (from the diagram);
- angles BCA and EDA are congruent (given);
- sides BC and ED are congruent (from the diagram).
So, SAS postulate can be applied.
SSS postulate cannot be applied, because it is not given that sides AB and AE are conruent.
Answer:
1320
Step-by-step explanation:
The sample ad 600 chips. They wanted to test 36000 chips. 600*60=36000
If 22 out of 600 chips were defective, and 600*60=36000
Then 1320 chips were defective out of the 36000 because 22*60=1320.
