Answer:

Probability from Urban Area = \frac{55}{89}

Probability NOT from Rural Area = \frac{83}{89}

Step-by-step explanation:

Total 178

Urban 110

Suburban 56

Rural 12

Hence, probability of x is number of x divided by total.

So, probability that she is from an urban area = 110/178 = 55/89

And

probability NOT a rural area (means urban and suburban which is 110+56=166) = 166/178 = 83/89

The difference between 7 7/8 - 3 1/4
Dima020 [189]
You could convert them into improper fractions first. 7 7/8 should become 63/8 and 3 1/4 should become 13/4. Then, change both fractions so they share a common denominator. I'll use 8. 
63/8-26/8 = 37/8, which is then converted into 4 5/8.
Hope that helped you.

(7n+4) +(8n-1) please solve this
meriva

Answer:

n= -6

Step-by-step explanation:

Simplifying

4 + -7n = -1(8n + 4) + 2

Reorder the terms:

4 + -7n = -1(4 + 8n) + 2

4 + -7n = (4 * -1 + 8n * -1) + 2

4 + -7n = (-4 + -8n) + 2

Reorder the terms:

4 + -7n = -4 + 2 + -8n

Combine like terms: -4 + 2 = -2

4 + -7n = -2 + -8n

Solving

4 + -7n = -2 + -8n

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add '8n' to each side of the equation.

4 + -7n + 8n = -2 + -8n + 8n

Combine like terms: -7n + 8n = 1n

4 + 1n = -2 + -8n + 8n

Combine like terms: -8n + 8n = 0

4 + 1n = -2 + 0

4 + 1n = -2

Add '-4' to each side of the equation.

4 + -4 + 1n = -2 + -4

Combine like terms: 4 + -4 = 0

0 + 1n = -2 + -4

1n = -2 + -4

Combine like terms: -2 + -4 = -6

1n = -6

Divide each side by '1'.

n = -6

Simplifying

n = -6
