(CO 6) If the linear correlation coefficient is -0.491, what is the
Sedbober [7]

The value of co-efficient of determination is 0.241.

<h3>What is the relationship between linear co-relation co-efficient and co-efficient of determination ?</h3>

The co-efficient of determination R² is similar to the linear correlation co-efficient.

We can think of co-relation of determination as a percentage. It gives us the data for how much percentage of data will fall within the linear co-relation.The higher the percentage the more data falls within.If the coefficient is 0.5 then 50% of data falls within the linear co-relation.

According to the given question

Linear correlation coefficient is -0.491

∴ Co-efficient of determination is (-.491)² which is equal to 0.241.

Simon spends £28 over 7 days. Each day, he spends 50p more than the previous day.
garik1379 [7]

This is about conversion of currencies.

<u><em>He spent £25 on the first day.</em></u>

  • We are told he had spent £28 over 7 days.

Each day, he spends 50 pence more than the previous day. This means that;

  • From conversion,

1 pound = 100 pence

Thus, 50 pence = (50 × 1)/100 = £0.5

  • If the money he spent on the first day is £x.
  • On second day, he would have spent a total of; £(x + 0.5)
  • On third day; x + 0.5 + 0.5= x + 1
  • On fourth day; x + 1 + 0.5 = x + 1.5
  • On fifth day; x + 1.5 + 0.5 = x + 2
  • On sixth day; x + 2 + 0.5 = x + 2.5
  • On seventh day; x + 2.5 + 0.5 = x + 3

  • Thus; x + 3 = 28

x = 28 - 3

x = £25

Two friends have a total of 60 coins. If the first fried gives 1/4 of his coins to the second friend, they will have an equal nu
kakasveta [241]

Answer:

The first friend has 40 coins.

Step-by-step explanation:

The statement says that the two friend have a total of 60 coins, which can be expressed as:

x+y=60 (1), where:

x is the first friend

y is the second friend

Also, the statement says that if the first friend gives 1/4 of his coins to the second friend, they will have an equal number of coins which means that if you subtract 1/4 of the coins the first friend has this would be equal to the number of coins the second friend has now, which is:

x-1/4x=y+1/4x

x-1/4x-1/4x=y

y=x-2/4x

y=x-1/2x (2)

Next, you have replace (2) in (1) and solve for x:

x+x-1/2x=60

2x-1/2x=60

3/2x=60

x=60/(3/2)

x=(60*2)/(1*3)

x=120/3

x=40

Finally, you can replace the value of x in (2) in order to find the value of y:

y=40-1/2(40)

y=40-(20)

y=20

According to this, the answer is that the first friend has 40 coins.
