Find the probability of rolling two dice and getting two odd numbersA.50% B.5.5% C.25% D.2.7%
Answers
One die has 6 numbers, 3 of which which are odd. That means each roll has a 50% chance of being odd.
To find the probability of rolling TWO odd numbers, we can multiply the 0.5 chance per roll by 2 to get:
0.5 * 0.5 = 0.25 or 25%
If you visualize the question, we have 4 possibilities:
Roll 1 is even and roll 2 is even.
Roll 1 is even and roll 2 is odd.
Roll 1 is odd and roll 2 is even.
Roll 1 is odd and roll 2 is odd.
Only 1 of the 4 possibilities results in both rolls being odd.

suize can run 2.5mile per hr faster then jeff. in the time it takes suize to run 6 mile jeff runs 4 mile find the speed of each runner
Answers
If you would like to know the speed of each runner, you can calculate this using the following steps:
6 miles ... x + 2.5 mile per hr (Suize) 4 miles ... x mile per hr (Jeff)
6 * x = 4 * (x + 2.5) 6 * x = 4 * x + 4 * 2.5 2 * x = 4 * 2.5 2 * x = 10 Jeff: x = 5 mile per hr
Suize: x + 2.5 = 5 + 2.5 = 7.5 mile per hr
Suize runs 7.5 mile per hr, and Jeff 5 mile per hr.
A rectangular horse stall has a width of 12 feet and a perimeter of 52 feet. What is the length of the horse stall?A) 13 feet B) 14 feet C) 28 feet D) 40 feet
Answers
Hi there. We know that the formula is P=2(l+w). So, let's solve for x :), l=P/2-w=52/2-12=14 ft. So, your answer would be B) 14 feet.
