Answer:
cos(a) = (√57)/11
Step-by-step explanation:
cos(a) = √(1 -sin(a)²) = √(1 -(8/11)²) = √(57/121)
cos(a) = (√57)/11
Answer:
5 + x
Step-by-step explanation:
x more than 5 is 5 + x
Answer:
D: Mittens
Step-by-step explanation:
We are given;
Population mean;
- Abyssinian: μ = 12
- Colorpoint shorthair: μ = 14
Population standard deviation;
- Abyssinian: σ = 1.5
- Colorpoint shorthair: σ = 1
Sample mean;
-Fluffy the Abyssinian: x¯ = 13
-Mittens the colorpoint shorthair; x¯ = 15
To find which cat had a longer lifespan, we need to find the z-score for both breeds and the one with the higher z-score is the one with longer lifespan.
Z-score formula is;
z = (x¯ - μ)/σ
For Fluffy the Abyssinian;
z = (13 - 12)/1.5
z = 0.667
For Mittens the colorpoint shorthair;
z = (15 - 14)/1
z = 1
Z-score of Mittens is higher and thus it has a longer lifespan.
