The average petrol consumption of a vehicle is 1 gallon per 35 km. The cost of 1 litre of petrol is $49. Fund the cost of petrol for a journey of 280 km.
(take 1 gallon=4.5 litres)
Answers
Step-by-step explanation:
Total petrol consumption of the journey=
Total distance travelled ÷ Average petrol consumption
[tex] = 280 \div 35 \\ = 8 \: gallons[/tex]
Given 1 gallon = 4.5 litres,
[tex]8 \: gallons \: = 8 \times 4.5 \\ = 36 \: litres[/tex]
Total cost of petrol for this particular journey = Petrol consumed x cost of 1 litre of petrol
[tex] = 4.5 \times 49 \\ = 220.50 \: dollars[/tex]
A bag contains 3 red marbles and 4 blue marbles. A marble is taken at random from the bag and replaced. Another marble is taken from the bag.
Work out the probability that the two marbles taken from the bag are the same colour.

Answer:
25/49
Step-by-step explanation:
probability of red and red is (3/7)(3/7) = 9/49
Probability of blue and blue is (4/7)(4/7) = 16/49
Probability of same color = prob. of red and red or prob. of blue and blue

solve for x!........
Answers
Answer:
x = 11
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
11x + 2 is an exterior angle of the triangle, then
11x + 2 = 5x + 10 + 58
11x + 2 = 5x + 68 ( subtract 5x from both sides )
6x + 2 = 68 ( subtract 2 from both sides )
6x = 66 ( divide both sides by 6 )
x = 11

What would the slope of a line be that is perpendicular to the line 3x + 2y = 67
Type your answer in the box below. Use the / for the fraction bar.
What would the slope of a line be that is perpendicular to the line 3x + 2y = 6?
And why is it right
Answers
Answer:
2/3
Step-by-step explanation:
The slope of a line that is perpendicular to another line must be the negative reciprocal of the other line. This means that the slope is flipped (3/2 would be 2/3, or 5 would be 1/5) and that the sign is also changed. If the slope of the other line is positive, then the slope of this line would be negative, and vice-versa.
First, we try to get the variable y by itself, so subtract 3x from that side of the equation and then divide everything by 2. So, it would now be y= -3/2 + 3.
Then, you find the negative reciprocal of 'm', so -3/2 would be change to 2/3

A traffic consultant wants to estimate the true proportion of cars on a certain street that have more than two occupants. She stands at the side of the road for two hours on a weekday afternoon and flips a coin each time a car approaches. If the coin comes up heads, she counts the number of occupants in the car. After two hours, she has counted 103 cars, 15 of which had more than two occupants. Which condition for constructing a confidence interval for a proportion has she failed to satisfy
Answers
Answer:
The data is a simple random sample from the population of interest.
Step-by-step explanation:
Conditions necessary to consider when constructing a confidence interval include using a large sample size, which should be greater Than or equal to 30 for n and a sample proportion of np ≤ 10. Importantly the sample must be a random sample drawn from the population, meaning that all the population of interest must have equal chances of being a part of the sample data. However, the scenariomabiveb, violates this condition as the sampling design is not completely randomized. Those who do not ply the route on that certain day have no Chaves of being part of the sample.
