Answer:
a square what
Step-by-step explanation:
Answer:
B. 61%
Step-by-step explanation:
When we have the standard deviation of a sample, we use the t-distribution.
The width of an interval is related to the margin of error, which is given by the following equation:
M = T*s
In which T is related to the confidence level(and the sample size) and s is the standard deviation of the sample. Higher confidence levels have higher values of T.
A higher margin of error means that the interval is wider. To have a higher margin of error, we desire a higher value of T, which is achieved with a higher confidence level.
So the correct answer is:
B. 61%
Answer:
-3/5
Step-by-step explanation:
Parallel lines have the same slope. If ab has a slope of -3/5 and is parallel to cd, the cd has a slope of -3/5
Answer:
The angles are complementary angles because they are 90

Answer:
All four Sets didn't work
Step-by-step explanation:
You should be doing hypothnose aka: a² + b² = c²
If they both equal that means they are a right triangle.
Set 1:
24² + 26² = 110²
576 + 676 = 10²
1252 = 12100
No
Set 2:
2² + 4² = 6²
4 + 16 = 6²
20 = 36
No
Set 3:
13² + 14² = 15²
169 + 196 = 15²
365 = 225
No
Set 4:
10² + 20² = 30²
100 + 400 = 30²
500 = 900
No
