Answer:
230 2/3 ft
Step-by-step explanation:
60 5/6 + 54 1/3 + 59 1/3 +56 1/6
5/6+1/3+1/3+1/6=
Put them into same denominator times 1/3 by 2
5/6+2/6+2/6+1/6= 10/6 (this is improper fraction, simplify and then turn it into mixed)
10/6= 5/3 = 1 2/3
60+54+59+56= 229 +1= 230 and the 2/3 before makes it
230 2/3 ft
Answer:
x^2 +3x -504
Step-by-step explanation:
Sort of do what you'd do to solve but in reverse. You need 21 for a zero, so the binomial factor would be (x-21) since if you set that = to zero you'd get 21. Same for -24. The binomial factor would be (x+24) since that would give you -24. Now that you have the two binomials, you can just multiply them and get the quadratic. :)
Answer:
0.789
Step-by-step explanation:
First, find the expected value (the mean).
μ = ∑ x P(x)
μ = (0) (0.359) + (1) (0.436) + (2) (0.180) + (3) (0.025)
μ = 0.871
Next, find the variance.
σ² = ∑(x − μ)² P(x)
σ² = (0 − 0.871)² (0.359) + (1 − 0.871)² (0.436) + (2 − 0.871)² (0.180) + (3 − 0.871)² (0.025)
σ² = 0.622
Finally, find the standard deviation:
σ = √0.622
σ = 0.789
