Answer:
r = 1.41 mm
Step-by-step explanation:
Given that,
The circumference of the flower, C = 8.9 mm
We need to find its radius. We know that,
Circumference, 
Where
r is the radius of the object
So, the radius of the object is equal to 1.41 mm.

Kindly check explanation
Step-by-step explanation:
The hypothesis :
H0 : μ = 3000
H0 : μ ≠ 3000
The test statistic :
(xbar - μ) ÷ (s/√(n))
xbar = 3500
μ = 3000
σ = 300
n = 30
(3500 - 3000) ÷ (350/√(30))
Test statistic = 7.824
Df = 30 - 1 = 29
Tcritical at 0.01 = 2.462
Test statistic > critical value ; we reject H0 ; and concluded that there is significant evidence that
μ ≠ 3000
It could be anything, except the number whose square is integer...
example -√10, -√11, -√12, -√13, -√14, -√15, -√17
Answer:
No. The two ratios do NOT form a proportion.
Step-by-step explanation:
Cross multiply.
13/6 : 2/1
13(1) : 6(2)
