Answer:
The angles are adjacent because they have a common side and vertex. Basically, they are both right next to each other.
x = 28
Step-by-step explanation:
When (x + 6)° and 56° are added together, they need to equal 90° since they are both parts of a right angle.
(x + 6) + 56 = 90
x + 62 = 90
x = 28
Answer:
Option C
Step-by-step explanation:
The central Limit Theorem says the sampling distribution of the sample mean is approximately normal under certain conditions
The conditions are
i) the population should be symmetrial. If population is skewed sample size should be sufficiently large atleast 30
ii) Samples should be drawn strictly at random
iii) the sample observations should be independent
Thus we find that option a is not necessary because even for skewed large sample size allows the theorem
Option b is not correct since if population is less than 30, sampling itself is not necessary.
Option d is also wrong since normality is not necessary
Only option C) The sample size must be large (e.g., at least 30) is the necessary condition
Answer:
Answer:
168 men
Step-by-step explanation:
We are given that 56 men can do a piece of work in 42 days
1 man can do work in days = 56 \times 42=235256×42=2352
Let the number of men be x who completes work in 14 days
So,x men can do work in =14 days
So, Number of men required to do work in 14 days = \frac{2352}{14}
14
2352
= 168168
Hence 168 men can complete work in 14 days.
