Solution :
Given :
X = the number of boys in a family of four children
Families having four children are chosen randomly.
The gender distribution in the four child family are equally probable.
Thus,

Answer:
3.5 cm
Step-by-step explanation:
2.5 is half of 5 so you divide 7 by 2 and you get 3.5

360° ÷ 10 ÷ 2 = 18°
So the length of the decagon side is:
10 × tan18° × 2 = 20 × tan18°
The area is: ½ × 20 × tan18° × 10 × 10 = 1000 × tan18°
≈ 324.9
.: <u>3</u><u>2</u><u>4</u><u>.</u><u>9</u> is the final answer.

Answer:
It will leave the sprinkler at speed of 
Step-by-step explanation:
We have given internal diameter of the garden hose 
So radius 
So area 
Water in the hose has a speed of 4 ft/sec
So 
Number of holes n = 36
Diameter of each hole 
So radius 
So area 
From continuity equation
3/8=0.375
2/5=0.4
0.38=0.38
0.375<0.38<0.4
therefore: 3/8,0.38,2/5
*Remember that you can convert fractions to decimals by dividing the numerator by the denominator! This makes it much easier to compare :)
