Answer:
Yes, they are congruent.
Step-by-step explanation:
Reflected triangles can be congruent
To be congruent two triangles must be the same shape and size. However one triangle can be reflected, that is, flipped over with respect to the other.
100,000
For each possible combination digit, there are 10 options: 0-9. Multiply ten by itself five times (for five digits) to find the number of combinations. This gives you 100,000 possible combinations.
Answer:
5%
Step-by-step explanation:
This is a significance test for a mean.
The 2 hypothesis here will be:
To determine the z-score of the error in the means you have to use this formula:
This mean that if the z score of a significance level is less than 1.897 the hypothesis that μ>2,200 is suggested.
10% -> z= 1.28
5% -> z = 1.645
1% -> z = 2.33
The most restrictive level of significance is 5%
