Answer:
Step-by-step explanation:
As the two pools, Family pool and Dog pool, are similar, their interior angles are equal and their corresponding sides are in the same proportion:
LMNO ~ PQRS
so LM/PQ = MN/QR = NO/RS = OL/SP
substituting in the given values
4/2 = 6/c = a/5 = 7/b
c = 6/2 = 3
a = 5*2 = 10
b = 7/2 = 3.5Answer:

Answer:
636.17251
Step-by-step explanation:
V = πr^2h = π·4.5^2·10 ≈ 636.17251
Answer: x = 15
Step-by-step explanation:
The formula for calculating the sum of the interior angles of a regular polygon is: (n - 2) × 180°. Where n is number of sides.
sum of angles = (n - 2) × 180
sum of angles = (7 - 2) × 180
sum of angles = 5 × 180
sum of angles = 900°
Now to find the value of x, we have to set each of the interior angles, added up, equal to 900°:
7x + 1 + 10x + 6x + 7 + 10x - 9 + 9x + 4 + 8x + 10 + 9x + 2 = 900
Combine like terms:
(7x + 10x + 6x + 10x + 9x + 8x + 9x) + (1 + 7 - 9 + 4 + 10 + 2) = 900
59x + 15 = 900
59x + 15 - 15 = 900 - 15 subtract 15 from both sides
59x = 885
59x/59 = 885/59 divide by 59 on both sides
x = 15
Answer: d .we are 99% confident that the true mean age of horses with laminitis is between 6.3 and 7.4 years old.
Step-by-step explanation:
- A x% confidence interval interprets that a person can be x% sure that the true population parameter lies in it.
Given : Veterinary researchers at a major university veterinary hospital .
He calculated a 99% confidence interval for the average age of horses admitted for laminitis, a foot disease that leaves the horse severely lame, as 6.3 to 7.4 years.
Here , Population parameter = Mean age of horses with laminitis
Interpretation: We are 99% sure that the true mean age of horses with laminitis is between 6.3 and 7.4 years old.
Hence, the correct option is d .we are 99% confident that the true mean age of horses with laminitis is between 6.3 and 7.4 years old.
