Answer:

5/7 is the correct answer

Step-by-step explanation:

The probability of the place is at city are:

= 5 / 7

Hope this help you :3

Answer 2

Answer:

Answer:

There are 7 places shown in the table which are , →{Rome, Tokyo, Houston, Peru, Miami, Toronto, Canada}

Out of which 5 are cities.

City={Rome, Tokyo, Houston,Miami, Toronto,}=5

It is given that a,place from the city is chosen.

Probability of an Event

$=\frac{\text{Total Favorable event}}{\text{Total possible outcome}}$

Probability of selecting a city from 7 places in which 5 are cities

$P(A)=\frac{_(1)^(5)\textrm{C}}{_(1)^(7)\textrm{C}}\n\nP(A)=(5)/(7)\n\nP(A^c)=1-P(A)\n\n=1-(5)/(7)\n\n=(2)/(7)$

Option B

The sum of 5 consecutive even numbers is 310. What is the third number in this sequence?

Answers

A simple way to solve for consecutive numbers is to divide the sum number by the number of numbers needed. So 310 ÷ 5, which equals 62. That is the middle consecutive number.

To find the other 4 numbers, since they are all even, sinply add 2 to the middle number to find one, add 2 to that to find another, subtract 2 from the middle number to fine the third, and subtract 2 from that to find the final one.

62 + 2 = 64
64 + 2 = 66
62 - 2 = 60
60 - 2 = 58

so your numbers are 58, 60, 62, 52, and 66. Together they add up to 310.

(I may have done this a non-standard way, bit it was the way that made the most sense in my head.)

Stacey has a square piece of cloth. She cuts 3 inches off of the length of the square and 3 inches off of the width. The area of the smaller square is 1/4 the area of the original square. What was the side length of the original square?A) 1 in.
B) 2 in.
C) 6 in.
D) 12 in.

Answers

Let the side length of the original square be x, then
1/4 x^2 = (x - 3)^2
x^2 = 4(x^2 - 6x + 9) = 4x^2 - 24x + 36
3x^2 - 24x + 36 = 0
3(x^2 - 8x + 12) = 0
x^2 - 8x + 12 = 0
x^2 - 2x - 6x + 12 = 0
x(x - 2) - 6(x - 2) = 0
(x - 6)(x - 2) = 0
x - 6 = 0 or x - 2 = 0
x = 6 or x = 2
but x cannot be 2 since the side length of the smaller square will be negative.

Therefore, the side length of the original square is 6 inches.
