Answer:
Interquartile Range= 0.079.
Step-by-step explanation:
Given,
The batting averages for seven baseball players are
0.176, 0.235, 0.272, 0.158, 0.201, 0.255, 0.303
First we have arrange the data in descending order or ascending order.
The ascending order of the data is
0.158, 0.176, 0.201, 0.235, 0.255, 0.272, 0.303
Median: The middle term of the data is the median of the data.
Here
Median = 0.235
First quartile: The median of the lower half of data.
The lower half of the data is 0.158, 0.176, 0.201
Third quartile: The median of the upper half of data.
The upper half of the data is 0.201, 0.255, 0.303
Interquartile: The difference between first quartile and third quartile.
Interquartile Range =
=(0.255- 0.176)
=0.079
Answer:
- OT⊥BA;T is the midpoint of BA-------Given
- ∠BTO and ∠ATO are right angles ---Definition of perpendicular lines
- ∠BTO≅∠ATO---------------------------------All right angles are congruent
- T is the midpoint of BA------------------ Given
- TA≅TB-------------------------------------------Definition of midpoint
- TO≅TO------------------------------------------Reflexive
- ΔBOT≅ΔAOT---------------------------------SAS
Step-by-step explanation:
Given that ⊥
and
is the midpoint of
As ⊥
,
∠ and ∠
are right angles (Definition of perpendicular lines)
⇒∠≅ ∠
(All right angles are congruent)
T is the midpoint of (given)
⇒≅
(Definition of midpoint)
≅
(Reflexive)
Therefore, Δ≅Δ
(by SAS criteria ):
conditions:
- ∠
∠
