Answer:
Step-by-step explanation:
Today's calculators have statistical functions built in.
A. Here we use:
normalcdf(10,310,205,35), WHICH returns 0.999.
B. normalcdf(135,275, 205,35) = 0.954
C. normalcdf(240, 10000, 205, 35) = 0.159
Answer:
x=-1 or x=-3/2
Step-by-step explanation:
1/2 x (10.2 + 12.2) x 12.6 = 141.12 cm^2
<span>3/8 of the animals are birds<span>
of the birds: 4/15 are birds of prey
If you want to know what fraction of the animals
at the zoo are birds of prey, you can calculate this using the following steps:
4/15 * 3/8 <span>= 12 / (15*8) = </span>1 / (5*2) <span>= </span>1 / 10 = 0.1
<span>Result: In the town zoo, </span>1/10 of animals are birds of prey<span>.</span></span></span>
