Ben rolled a number cube numbered one through six. It landed on an odd number 30 times. What is the probability that it lands on an odd number on the next roll?

Answers

Answer:

1 /2

Step-by-step explanation:

Sample space of number cube : (1, 2, 3, 4, 5, 6)

Odd numbers on cube : (1, 3, 5) = 3 odd numbers

Since each roll of number cube is independent, the number of times it has landed between fire does not matter :

Therefore, probability of landing on a odd number is :

P = required outcome / Total possible outcomes

P = 3 / 6

P = 1/2

What is the measure of the smaller of two complementary angles if one angle is 4x and the other is 2x + 18?

Answers

Answer:

42°

Step-by-step explanation:

4x + 2x + 18 = 90        because they are complementary angles (add up to 90°)

reduce:

6x = 72

x = 12

one angle = 4(12) = 48°

other angle = 2(12) +18 = 42°

250 percent of 18 is what? [please type an explanation]​

Answers

Answer:

Answer is 45

Step-by-step explanation:

I hope it's helpful!

the answer is 45
to find the answer you would find out 10% first- in other words divide by 10 to get 25
next you would need to find 1% by dividing by 100 so that would be 2.5
times 2.5 by 8 to get 8%
add the 25 and 20 to equal 45

Without graphing, determine whether the system of linear equations has one solution, infinitely many solutions, or no solutions.

y=6x+2y=6x+2 and y=6x-4y=6x−4

Answers

Answer:

          The system has no solutions.

Step-by-step explanation:

y = 6x + 2     ⇒    6x - y = -2

y = 6x - 4      ⇒    6x - y = 4

a₁ = a₂ = 6  ,  b₁ = b₂ = -1 ,  c₁ = -2 , c₂ = 4

a₁ = a₂ = 6   and  b₁ = b₂ = -1  and  c₁ ≠ c₂  ⇒  NO SOLUTIONS

Joshua drove his car a distance of 321.7 miles, and it required 13.6 gallons of gasoline (petrol). How many liters of fuel will it take to go 100 kilometers?

Answers

Answer:

1005.68 litres

Step-by-step explanation:

Steps to answering this question

Convert miles to kilometers and gallons to litresThen divide the converted miles by the converted gallons Multiply the value gotten from the above step by 100 km

1 gallon = 3.78541 litres

13.6 gallons x 3.78541 = 51.48 litres

1 mile = 1.60934 km

321.7 miles x 1.60934 = 517.72 km

Litre needed per kilometer =  517.72 km / 51.48 = 10.06

Litres needed for 100 km = 100km x 10.06 = 1005.68 litres
