Aside from the phone number, other
categorical variables in the survey that was conducted are family size, dad's
occupation, whether mom works, and kind of pets. Remember that the categorical
variable is also known as a qualitative variable. It means that categorical
variables are mostly descriptions of something, can be an individual or group
of people or things. Although phone number is entails a numerical figure, but
it doesn’t necessarily give percents or counts, or even numbers which makes it
also a part of the categorical variable.
Answer:
The angle of rotation of the boats direction from start to finish = 50.36⁰ to east towards north.
Step-by-step explanation:
Let x axis be east direction and Y axis be north direction.
We have first boat travels 30 miles north
Displacement = 30 j
20 miles east
Displacement = 20 i
40 miles northeast
Displacement = 40 cos 45 i + 40 sin 45 j = 28.28 i + 28.28 j
Total displacement = 48.28 i + 58.28 j
Angle, tanθ = 58.28/48.28
θ = 50.36⁰
The angle of rotation of the boats direction from start to finish = 50.36⁰ to east towards north.
Volume sphere A V1 = (4/3)πR³
R=∛((3/4)V1/π)
Volume sphere B V2= (4/3)πr³
r=∛((3/4)V2/π)
R-r = ∛((3/4)40/π) - ∛((3/4)10/π) ≈ 0.8 inch
Answer C. 0.8 inch.
Answer:
72 full bags
Step-by-step explanation:
A pound is 16 ounces
22.75 lbs * 16 =364 ounces
Take the total ounces and divide by the ounces per bag
364 ounces/5 ounces per bag
72.8 bags
72 full bags, 1 bag 4/5 full
Round down since the decimal is a partially filled bag
72 bags
72 full bags
