Do this and then simplify the result
Answer:
n = 61 costumers
Step-by-step explanation:
For calculating the number of costumers he should sample we use the next equation:

Where E is the error that we are prepared to accept, in this case E = 0.15
How we don't know the value of p, we can estimate it like p = 0.5
∝ = 1-0.98 = 0.02
1-∝/2 = 0.99


n = 60.32 costumers
n ≈ 61 costumers
I think the answer is -1=x-3<4
Answer:
Slope = -2.000/2.000 = -1.000
x-intercept = 3/1 = 3.00000
y-intercept = 3/1 = 3.00000
Answer:
12 ft²
50 ft²
Step-by-step explanation:
∆ABD = ∆CBD
Perimeter of ∆ABD = 12 ft²
Perimeter of triangle ∆CBD
If ∆ABD = ∆CBD
Then, Perimeter of ∆CBD = 12 ft²
∆ABC = ∆CDA
Area of ∆ABC = 25 ft²
Then the area of rectangle ABCD = Area of ∆ABC + Area of ∆CDA
= 25 ft² + 25 ft²
= 50 ft²
