Answer:
option B) ΔABE ∼ ΔADC
Step-by-step explanation:
<u><em>The picture of the question in the attached figure</em></u>
we know that
If two triangles are similar, then its corresponding sides are proportional and its corresponding angles are congruent
In this problem
Triangles ABE and ADC are similar by AA Similarity Theorem
because
m∠ ABE≅m∠ADC
m∠ BAE≅m∠DAC
The corresponding sides are
AB and AD
BE and DC
AE and AC
so
Answer:
hmmmmmmmmmmmmmmmmmmm probably the part when you say half
Answer:
Step-by-step explanation:
Set up hypotheses as
(Left tailed test at 5% level)
Sample mean = 53.4
Sample std dev s = 4.4
Sample std error = 4.4/sqrt 50 = 0.6222
Mean diff = 3.4
Test statistic = Mean diff/std error = 0.5464
(t test only can be used as population sigma is not known)
df = 50-1 =49
p value = 0.2939
Since p>0.05 we accept null hypothesis
Specification has not been met.
The median would be a better measure of central tendency when the data is skewed (or if the frequency distribution for the data is skewed).
