Answer:
25.4, 28.6
Step-by-step explanation:
Given parameters
sample size, n = 24
sample mean, X = 27
population standard deviation, s = 3
critical value, Zα/2, where α = 0.01
99% confidence Interval, CI, is given as follows
CI = X ± Zα/2 × (s/√n)
Zα/2 = Z0.01/2 = Z0.005 = 2.576
CI = 27 ± 2.576 × (3/√24)
= (25.42 ,28.57)

Answer:
No, diagonal of square C is 70.71ft
Step-by-step explanation:
Given in the question that length of one square = 5 ft
Length of Square C = 10 small squares
1 square = 5 ft
10 square = 5ft * 10
= 50 ft
As we know that in a square all side are of equal length and make an angle of 90° at each corner.
So, by using pythagorus theorem
Diagonal of square² = side² + side²
Diagonal of square² = 2side²
Diagonal of square = √(2side²)
Diagonal of square = √2 (side)
where side = 50 ft
Diagonal of square = √2 (50)
Diagonal of square = 70.71 ft

Answer:
1. y + 10 - 3/2y = -y/2 + 10
2. 2r+ 7r-r - 9 = 8r - 9
3. 7 + 4p-5+p+2q = 2 + 5p + 2q
Step-by-step explanation:
basically you can add terms that have the same variable
integers can be added together, Xs can be added, Zs, Ys, As, Bs, Cs, you get the point
1. y + 10 - 3/2y = -y/2 + 10
2. 2r+ 7r-r - 9 = 8r - 9
3. 7 + 4p-5+p+2q = 2 + 5p + 2q (do not add different variables p and q ) together
