If we divide  60 into say hmmm two integers, and those integers are say "a" and "b", then  a + b = 60, therefore, a = 60 - b.

\bf \stackrel{\textit{one part is divided by 6}}{\cfrac{a}{6}}~~+~~\stackrel{\textit{the other part is divided by 8}}{\cfrac{b}{8}}~~=~~9
\\\\\\
\cfrac{60-b}{6}~~+~~\cfrac{b}{8}=9\impliedby 
\begin{array}{llll}
\textit{let's multiply both sides by}\\
\textit{the LCD of 24}
\end{array}
\\\\\\
24\left( \cfrac{60-b}{6}~~+~~\cfrac{b}{8} \right)=24(9)\implies 240-4b+3b=216
\\\\\\
-b=-24\implies b=\cfrac{-24}{-1}\implies b=24

what's the first integer?  well, a = 60 - b.

A corporation has 11 manufacturing plants. Of these, seven are domestic and four are outside the United States. Each year a perf
nikdorinn [45]

Answer:

The probability that a performance evaluation will include at least one plant outside the United States is 0.836.

Step-by-step explanation:

Total plants = 11

Domestic plants = 7

Outside the US plants = 4

Suppose X is the number of plants outside the US which are selected for the performance evaluation. We need to compute the probability that at least 1 out of the 4 plants selected are outside the United States i.e. P(X≥1). To compute this, we will use the binomial distribution formula:

P(X=x) = ⁿCₓ pˣ qⁿ⁻ˣ

where n = total no. of trials

           x = no. of successful trials

           p = probability of success

           q = probability of failure

Here we have n=4, p=4/11 and q=7/11

P(X≥1) = 1 - P(X<1)

          = 1 - P(X=0)

          = 1 - ⁴C₀ * (4/11)⁰ * (7/11)⁴⁻⁰

          = 1 - 0.16399

P(X≥1) = 0.836

The probability that a performance evaluation will include at least one plant outside the United States is 0.836.

Feliz [49]

Answer:

1,500 people

Step-by-step explanation:

Remember that

1\ ft= 12\ in

Convert ft to in

150\ ft=150*12=1,800\ in

<em>Divide the length of a row by the space occupied by one person</em>

1,800/24=75\ persons

<em>Multiply by the number of rows to determine the total people that can fit into the stands</em>

75(20)=1,500\ people

Answer: 29%

Step-by-step explanation:

You need to divide the rent, 8265, by the amount of money he earns.

8265/28500 is .29
