Answer:
Increase
Step-by-step explanation:
The researcher records the following estimates: 450, 426, 310, 500, and 220.
The mean of these estimates is derived below.
Mean = (450+426+310+500+220)/5
=1906/5=381.2
If the researcher removes the estimate of 220.
The mean of the other numbers will be:
Mean =(450+426+310+500)/4
=1686/4=421.5
By comparison of the two mean, we can see that the value of the mean will increase.
Answer:
∠A = 120°
∠B = 60°
Step-by-step explanation:
Since, ∠A and ∠B form a linear pair.
Therefore,
∠A + ∠B = 180°.....(1)
It is given that:
∠A = 2∠B..... (2)
From equations (1) & (2)
2∠B + ∠B = 180°
3∠B = 180°
∠B = 180°/3
∠B = 60°
So, ∠A = 2∠B = 2*60°
∠A = 120°
