2n2 i’m gonna assume is 2n^2
and n2 is 2n
2n^2-10n+5
Answer:
- ∠1≅∠2-------------------------(Given)
- m∠1=m∠2-------------------(Definition of congruent angles)
- ∠ABP, ∠1 and ∠DCP,∠2 form linear pair---------------Linear pair
- m∠ABP+m∠1=180° and m∠DCP+m∠2=180°--------definition of linear pair
- ∠ABP≅∠DCP--------------------If equals are subtracted from equals, the remainders are equal
- AP≅DP----------------------------Given
- ΔABP≅ΔDCP-------------------AAS
Step-by-step explanation:
Given, ∠1≅∠2, ∠3≅∠4 and AP≅DP,
∠1≅∠2(given)
⇒m∠1=m∠2(definition of congruent angles)
- ∠m∠1=180° and ∠+m∠2=180° (Linear Pair)
180°=180°(Reflexive)
⇒m∠m∠1=m∠+m∠2
But m∠1 =m∠2 (definition of congruent angles)
⇒m∠m∠1=m∠+m∠1
m∠=m∠=(GIven)
Therefore, ΔΔ (by AAS criteria)
condition are:
- m∠1=m∠2 (Angle)
- m∠=m∠ (Angle)
- AP=DP (Side)

Answer with explanation:</h2>
Let be the population mean.
Null hypothesis :
Alternative hypothesis :
Since the alternative hypothesis is left tailed, so the test is a left-tailed test.
Sample size : n=5 <30 , so we use t-test.
Test statistic:
Critical t-value for t=
Since, the absolute value of t (1.79) is less than the critical t-value , so we fail to reject the null hypothesis.
Hence, we have sufficient evidence to support the company's claim.
The distance is 52.5 cm when weight is 7kg
Step-by-step explanation:
Distance is 15 cm when weight is 2 kg
We need to find the distance d when weight is 7 kg
Since distance and weight varies directly so,
Solving the above expression:
So, The distance is 52.5 cm when weight is 7kg
