Mia wants to borrow £6000 and repay it, with interest, after two years. she sees two offers for loans: offer 1 compound interest 3% per year offfer 2 compound interest first year 1% second year 3% mia says, iwill payback the same amount because the average of 1% and 5% is 3% is she correct?

Answers

Answer:

she is wrong, offer 2 results in lower interests

Step-by-step explanation:

total amount paid if offer 1 is accepted:

$6,000 x (1 + 3%)² = $6,000 x 1.0609 = $6,365.40

she will pay $365.40 in interests

total amount paid if offer 2 is accepted:

($6,000 x 1.01) x 1.05 = $6,060 x 1.05 = $6,363

she will pay $363 in interests

Compounding interest refers to interest that earns more interest itself, e.g. in the first offer, the $180 of interests charged for the first year will earn $5.40 in extra interests. While offer 2 only charges $60 in interests during the first year which will in turn earn $3 of interests. The difference between both offers is that interest charges in offer 1 earn more interests than the interest in offer 2 = $5.40 - $3 = $2.40

value of T = 20

Step-by-step explanation:

When a coin was tossed, it came up heads 12 times and tails 8 times.
What percent of the time did it come up tails?

Answers

Answer: 40% of the time the coin came up tails.

Step-by-step explanation:

The coin is tossed 20 times. Of those 20 times, it came up tails 8 times (8/20). 8/20 = 0.4 = 40%

Answer:

It’s 1/2 (the probability of getting either heads or tails) to the power of 8 (for 8 tosses).

Step-by-step explanation:

Two of your friends go bowling. One friend rents a pair of bowling shoes for $3 and bowls 3 games. The other friend brings his own bowling shoes, bowls 4 games and buys a soda for $0.50. Both friends spend the same amount of money. Show how you can write and solve an equation to find the cost of one game.

Answers

Answer: The cost of each game is $2.50

Step-by-step explanation:

Let's find the equations for each friend:

Friend 1:

Pays $3 for the shoes, and plays 3 games, then if X is the cost of each game, Friend 1 pays a total of:

$3 + 3*X

Friend 2:

This friend buys a soda for $0.50, and he plays 4 games, remember that the cost of each game was X. then this friend pays:

$0.50 + 4*X

And we know that both friends pay the exact same amount, then we can write:

$3 + 3*X = $0.50 + 4*X

And solve this for X.

We need to isolate X, then we can move all the terms with X to the right, and all the terms without X to the left:

$3 - $0.50 = 4*X - 3*X

$2.50 = (4 - 3)*X = X

This means the cost of each game is $2.50

Answer: 31.18

Step-by-step explanation:

The problem is focused on mainly the right triangle made up of points M, Q, and R. This problem can be solved with the base formula, b = a · tan(β) where a = the length of line MR, β = m∠MQR, and b is the unknown length of RQ.

Given:

RQ = 18 · tan(60°)

Point M is the midpoint of line PM and line MR. Since MP is equal to 18, MR has to be 18 as well. This means that the value of a is 18.

The vertex of ∠MQR is Q, which is 60°.

Step 1: Find the tangent of 60°

The tangent of 60° is √3

Step 2: Solve

RQ = 18 · √3

18 · √3 = 31.18

RQ is equal to 31.18

A park has the dimensions indicated in the diagram. Which expression represent the perimeter of the park?

Answers

Answer:

78m.

Step-by-step explanation:

Since we are not given any dimension we can use the following dimension.

Let the park be rectangular in nature

Length = 25m

Width = 14m

Perimeter = 2(L+W)

Perimeter = 2(25 + 14)

Perimeter = 2(39)

Perimeter = 78m

Hence the perimeter of the park is 78m.

Note that the dimension were assumed and any values can be used using similar calculation.

In 2005, the Centers for Disease Control proposed deliberately combining a deadly bird flu virus with a very contagious human flu virus to understand whether and how it might cause a worldwide outbreak, or "pandemic. Scientists said the lab experiments would help them understand what might already be happening naturally. . . .But other people thought such research was a terrible idea. What if these viruses escaped the lab by mistake? What if a government or terrorist organization wanted to use the viruses against their enemies?In 2013, two research groups outside the United States went ahead and conducted their own experiments. One group, led by Ron Fouchier of Erasmus University in the Netherlands, showed that the highly lethal mixed up flu virus could infect and kill ferrets. A few months later, a Chinese group led by Chen Hualan at Chinas Harbin Veterinary Research Institute showed the recombined virus could infect and kill guinea pigs. Both groups ran their studies before a worldwide ban on this type of research was put into place in 2012.One of the main ideas presented in this passage is the controversy over whether or not flu research is safe. What do these paragraphs suggest about the safety of such research?A) A worldwide ban on dangerous flu research was put into place in 2012, so the threat of people using flu viruses to attack others no longer exists.B) Since all of the information that could be learned from such research has already been discovered, scientists no longer need to create new flu viruses, and therefore the controversy is over.C)Although none of the deadly flu viruses made for research have been used by dangerous people, since that possibility still exists, the ban on the research might be important.D) The research has already resulted in the deaths of animals, so people who once thought creating and researching new flu viruses was important are no longer supporting it.

At that time Puddleby was only quite a small town. A river ran through the middle of it; and over this river there was a very old stone bridge, called Kingsbridge, which led you from the market-place on one side to the churchyard on the other.Sailing-ships came up this river from the sea and anchored near the bridge. I used to go down and watch the sailors unloading the ships upon the river-wall. The sailors sang strange songs as they pulled upon the ropes; and I learned these songs by heart. And I would sit on the river-wall with my feet dangling over the water and sing with the men, pretending to myself that I too was a sailor.For I longed always to sail away with those brave ships when they turned their backs on Puddleby Church and went creeping down the river again, across the wide lonely marshes to the sea. I longed to go with them out into the world to seek my fortune in foreign landsAfrica, India, China and Peru! When they got round the bend in the river and the water was hidden from view, you could still see their huge brown sails towering over the roofs of the town, moving onward slowlylike some gentle giants that walked among the houses without noise. What strange things would they have seen, I wondered, when next they came back to anchor at Kingsbridge! And, dreaming of the lands I had never seen, I'd sit on there, watching till they were out of sight.Which phrase from the excerpt most clearly suggests what Tommy thinks a life at sea will bring?
