This problem can be addressed by applying the normal approximation to a binomial distribution.
Calculations:
Mean (μ) = np = 10,000 × 0.5 = 5,000
The standard deviation (σ) is given by:
The probability of obtaining more than 5,100 tails is 0.0228, whereas the probability of fewer than 5,100 tails is 0.9772.
Thus, the odds of having more than 5,100 tails are:
0.0228 : 0.9772 = 1 : 42.86.
Respuesta: 1.8 bolsas
Explicación paso a paso:
A partir de la pregunta, considerando que Robby tiene 4 4/9 bolsas de comida para mascotas, 2/5 eran comida para perros.
2/5 de 4 4/9 = comida para perros.
Convierte 4 4/9 a fracción impropia= 40/9.
2/5 de 40/9 implica 2/5 × 40/9.
= 16/9.
= 1.78 o 1.8.

Answer:
The appropriate answer is 72 + 4 × x 
400.
Step-by-step explanation:
Pine Bluff Middle School's dance committee raises $72 from a bake sale and anticipates $4 for each ticket sold for the Spring Fling dance.
The cost of the dance will be $400.
Let x represent the number of tickets the committee could sell.
The total income amounts to 72 + 4 × x.
After paying for the dance, which costs $400, the committee should have some funds remaining.
This leads to the inequality used to ascertain the number of tickets the committee can sell while ensuring they have money left after the dance expense, formulated as:
72 + 4 × x 400.
To tackle this mathematical issue, we should first gather and evaluate the known values alongside the unknowns posed by the problem.
Annie traveled five times the total of the hours Brian traveled and an additional 2. Together, they totaled 20 hours. Calculate the individual hours.
Equation,
<span><span>
1. </span><span> 5(y) + 2 = 20</span></span>
<span><span>2. </span><span> 5y = 20 – 2</span></span>
<span><span>
3. </span><span> 5y = 18</span></span>
<span><span>4. </span><span> Y = 18 / 5</span></span>
<span><span>
5. </span><span> Y = 3.6</span></span>
<span><span>
6. </span><span> 5y = 5(3.6)</span></span>
<span><span>
7. </span><span> Annie = 18</span></span>
Therefore, Annie traveled for 18 hours while Brian spent 3.6 hours traveling.
