Solve for n:<br> (n+4)/10 = (n-8)/2
nalin [4]

Answer:

n=11

Step-by-step explanation:

(n+4)/10 = (n-8)/2

We can solve using cross products

(n+4) * 2 = 10 * ( n-8)

Distribute

2n+8 = 10n -80

Subtract 2n from each side

2n+8-2n = 10n-80-2n

8 = 8n-80

Add 80 to each side

8+80= 8n-80+80

88 = 8n

Divide each side by 8

88/8 = 8n/8

11 = n

Please reference attached image for the problem that requires solving. Thank you so much for taking the time to help.
Lemur [1.5K]

Explanation:

The number of times the 6-sided number cube will be rolled will is

750

Let the numbers greater than 4 be represented below as

E_1\begin{gathered} E_1=\lbrace5,6\rbrace \\ n(E_1)=2 \end{gathered}

The number of sample space will be

n(S)=6

The probability of rolling a number greater than 4 will be calculated below as

\begin{gathered} Pr(E_1)=\frac{n(E_1)}{n(S)} \\ Pr(E_1)=\frac{2}{6}=\frac{1}{3} \end{gathered}

Hence,

To calculate the number of times a number greater than 4 will be rolled will be calculated below as

\begin{gathered} =Pr(E_1)\times750 \\ =\frac{1}{3}\times750 \\ =250times \end{gathered}

Hence,

The final answer is

\Rightarrow250\text{ }times
