Answer: 720
Step-by-step explanation:
5%=36
1%=36/5
1%=7.2
100%=7.2*100
100%=720 students
Step-by-step explanation:
There are 4 * 4 = 16 outcomes from spinning these spinners. You get an odd number by multiplying an odd number by an odd number. Since there are 2 odd numbers on both spinners the successful outcomes are 2 * 2 = 4 so probability is 4 / 16 = 1 / 4.
768 is the sum of your problem
Answer:
a + b = 90°
Step-by-step explanation:
If sum of two angles are 90°, then the two angles are complementary
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.
