Answer:
The zoo made $82762.50
Step-by-step explanation:
Children : 4.50 * 4012 = 18,054.00
Adults : 7.25 * 8024 = 53,174.00
Senior : 5.75 * 2006 = 11,534.50
Add these totals up = $82762.50
infants are free that's why there's no math for them.
hope this helps
Answer:
x = -21/11
Step-by-step explanation:
6(2x + 4)2 = (2x + 4) + 2
12(2x +4) = 2x + 4 + 2
24x + 48 = 2x +6
22x = -42
x = -21/11

Answer: the probability it will come up heads 25 or fewer times is 0.019
Step-by-step explanation:
Given that;
n = 50
p = 0.65
so, q = 1 - p = 0.35
np = 50 × 0.65 = 32.5 ≥ 10
nq = 50 × 0.35 = 17.5 ≥ 10
so, we need to use Normal Approximation for the Binomial Distribution
μ = np = 50 × 0.65 = 32.5
σ = √(npq) = √( 50 × 0.65 × 0.35 ) = 3.3726
now, the probability that it will come up heads 25 or few times will be;
⇒ P( x≤25)
{using continuity correction}
⇒ P[ z < (25.5 - 32.5)/3.3726 ]
⇒ P[ z < -2.0755 ]
using z-table
= 0.01923 ≈ 0.019 { 3 decimal places}
Therefore the probability it will come up heads 25 or fewer times is 0.019
