Answer:
a.$138
b.$197
Step-by-step explanation:
(/=division)
a.415/30=138
b.138/7=197
Hope I helped :D
About 3 gallons of blue paint will be needed because if you add 175+175 it equals 350 and then add another 175 it equals 525.
You have to divide so it would be
X+2/2 = y do you see what I did so then it would be
X+y = xy =2=2xy so you have to first divide then combine like terms

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.
