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
Hey again, you can use trigonometric ratios for this one. You are trying to find the side length opposite of angle G, when you have the adjacent side length value known. You can use TOA, or tan((opposite/adjacent)) . Tan(50) = x/10
X= 11.92 cm
Answer:
Fraction: 1/ 5 n= 7
Step-by-step explanation:
To find n first you cross multiply : 2/ 10 * n / 35
= So we multiply 10 and n ( answer = 10n)
= Then 2 and 35 ( multiply) ( answer = 70)
Now algebra
70 = 10n
Divide both sides by 10
10n / 10 = 70 / 10
n = 7
The fraction becomes 7 / 35
When this is simplified the answer is 1 / 5
To simplify you divide the numerator and denominator of the fraction by 25 ( GCF )
HOPE THIS HELPED
Since its roots are -4 and 2 and a = 1 [The coefficient of x^2] we know that x^2 + bx + c = (x - (-4)) (x-2)=(x+4)(x-2) = 0. Using the distributive property we get, x^2 + 2x - 8 = 0. By equating coefficients (common strategy for partial fractions and undetermined coefficient method of solving ODE), we get b = 2 and c = -8.
