2 answers:

5 0

The answer is either A, or B. Answer D, is not appropriate for a survey of 100 dogs. Answer C, is also not correct, because it doesn't exactly matter out of 100 dogs. Answer A, is more accurate, then Answer B, because it is more of a statistical question, as in surveys, we want statistics. Thus, I must go with A) - <span>What is the number of dogs in the shelter that are more than 5 years old?</span>

It was B, because that is more of a statistical question than because A is an exact answer ans statistical questions have variability.

On the 1st of January 2014 Carol invested some money in the bank account. the account pays 2.5% compound interest per year on fi

stira [4]

Answer:

The initial amount invested into the account on 1st January 2014 was £23,360

Step-by-step explanation:

In order to calculate the initial deposit in question, we will have to make use of the formula for calculating compound interest:

Fv = Pv × (1 + r)^t ------ since it was compounded annually.

Where Fv = future value

Pv = present value

r = interest rate

t = time (years)

Here, r = 2.5% or 0.025

t = 1 year

Let x represent this initial deposit. Then at the end of the year(31st Dec 2014), we will have:

Fv = x × (1 + 0.025)^1

Fv = x × (1.025)

Fv = £1.025x

Therefore, the amount that will be in the account as at 31st Dec 2014 is = £1.025x.

Now, if the owner of the account then withdraws a sum of £1,000 from the account on the 1st of Jan 2015, then the balance that will be in the account after the withdrawal will be = £1.025x - 1000. This will now be the principal or present value that will accrue interest for the year - 2015.

Again, we were told that that the future value or the balance on the 1st of Jan 2016 will be £23,517. We will then once again use the compound interest formula, making the present value (1.025x - 1000) the subject of the formula so that we can solve for x. Once "x" is determined, then we have exposed the initial deposit that was made into the account on the 1st of January 2014.

Fv = Pv × (1 + r)^t

Here,

Fv = 23,517

Pv = 1.025x - 1000

r = 0.025

t = 1

23,517 = 1.025x - 1000 × (1 + 0.025)^1

23,517 = 1.025x -1000 × (1.025)

23,517 = 1.050625x - 1025

1.050625x = 23,517 + 1025

1.050625x = 24,542

Then making "x" the subject of the formula:

x = 24,542/1.050625

x = £23,360

Therefore, the initial deposit that Carole made into the account on 1st January 2014 was £23,360

What’s the distance between (3,4) , (7,2)

Reptile [31]

Answer:

$D= 4.47$

Step-by-step explanation:

Here we are given with two coordinates and asked to determine the distance between them.

Here we are going to use the distance formula, which is given as under

$D=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}$

Where

$(x_1,y_1) = (3,4)$

$(x_2,y_2) = (7,2)$

Replacing these values in the distance formula

$D =\sqrt{(7-3))^2+(2-4)^2}$

$D =\sqrt{(4)^2+(-2)^2}$

$D =\sqrt{16+4}$

$D =\sqrt{20}$

$D= 4.47$

2 1/2+(-7/6)-1 3/4.

KIM [24]

Okay. So, what you do is subtract the negative number from the positive number. Let’s find the lowest common multiple of each number. The lowest common multiple (LCD) is 6. So we set this problem up as 2 3/6 - 1 1/6. When we subtract both numbers, you get 1 2/6. or 1 1/3 in simplest form. Now, you subtract again. Because 1 3/4 is greater than the number we are subtracting from, which is 1 1/3, the answer will be negative. The LCM of 3 and 4 is 12, so 12 will be the LCD. Let’s subtract to get our negative difference. 1 9/12 - 1 4/12 is 5/12. Plug in the negative symbol and you have -5/12. There. The answer is -5/12.
