The greatest percent error among the predictions time of the race is: 3.15 %

Although part of your question is missing, you might be referring to this dot plot that shows the predictions for the winning time (see image attached)

To solve this exercise, we have to apply the percentage formula:

Error (%) = [(prediction time – real time) / real time] * 100

Information about the problem:

Applying the percentage formula, we have:

Error (%) = [(prediction time – real time) / real time] * 100

Error (%) = [(22.9 seconds – 22.2 seconds) / 22.2 seconds] * 100

Error (%) = [(0.7 seconds) / 22.2 seconds] * 100

Error (%) = 0.0315 * 100

Error (%) = 3.15 %

Step-by-step explanation:

you can plus for obtain a multiply

5×-2y=3

Step-by-step explanation:

for the lengths of BC and AC we can count the squares, because the lengths of these lines are the sum of the side lengths of each inducing square.

1.

BC = 7 - -2 = 7 + 2 = 9 cm

2.

AC = 13 - 1 = 12 cm

3.

but for AB we cannot do that, because AB consists of the lengths of all the diagonals of the squares. and a diagonal must always be longer than any side.

just look at the triangle : it is clear that AB must be longer than AC.

no, for a line that goes across the grid squares we need other methods.

in our case, we have a right-angled triangle and can use Pythagoras

c² = a² + b²

c being the Hypotenuse (the side opposite of the 90° angle), a and b being the legs of the triangle (enclosing the 90° angle).

AB is in our case the Hypotenuse, and we get

AB² = 12² + 9² = 144 + 81 = 225

AB = sqrt(225) = 15 cm

4.

as explained, we used Pythagoras.

5.

the coordinates for a midpoint between 2 points (x1, y1) and (x2, y2) are simply

((x1+x2)/2, (y1+y2)/2)

A = (13, -2)

B = (1, 7)

C = (1, -2)

midpoint AC = ((13+1)/2, (-2 + -2)/2) = (14/2, -4/2) =

= (7, -2)

the x coordinate is 7.

6.

midpoint BC = ((1+1)/2, (7+ -2)/2) = (2/2, 5/2) = (1, 2.5)

the y coordinate is 2.5

7.

midpoint AB = ((13+1)/2, (-2+7)/2) = (14/2, 5/2) =

= (7, 2.5)

Answer:

It is given that P = principal, R = rate of interest and T = time

Formula to find compound interest is:

A = P(1 + R/100)^T

where A = amount received after n years

P = principal amount invested

R = rate of interest

T = time for which the amount is invested

The interest earned on savings that are computed using both the original principal and the interest accrued over time is known as compound interest.

It is thought that Italy in the 17th century is where the concept of "interest on interest" or compound interest first appeared. It will accelerate the growth of a total more quickly than simple interest, which is solely calculated on the principal sum.

Money multiplies more quickly thanks to compounding, and the more compounding periods there are, the higher the compound interest will be.

There wasn't an image put to choose which graph it would be.

Step-by-step explanation:

Let us organize the information first. The game consists in picking up a numbered duck. Let us denote the number of the duck as xx. The possible prizes are

1≤ x≤ 60 consolation prize

60 ≤ x ≤ 70 stuffed duck

70≤ x ≤ banana

We have 75 possible numbers equally likely to select, and 1111 outcomes where we win the stuffed duck

60, 61, 62, 63, 64, 65, 66, 67, 68, 69 and 70

Therefore, the probability of winning a stuffed duck is

p(60 ≤ x ≤ 70) = 11/75= 0.146

The event of not winning a duck or a banana is that of winning the consolation prize, that is, picking a number 1 ≤x ≤ 60.

Those are 59 equally likely to occur outcomes. Then we have

c= 59/75= 0.786

To check whether this result is right, we can use the complementary events law. That is, the probability of not winning a duck or a banana is 11 minus the sum of the probabilities of winning a duck or a banana. Mathematically this is

p (1 ≤ x ≤ 60) = 1-(p (60≤x≤70)+p(70≤x≤75)

p (1≤ x ≤ 60) = 0.786

In mathematics, the additive inverse of a number a is the number that, when added to a, yields zero. This number is also known as the opposite, sign change, and negation.

For example, the additive inverse of 7 is −7, because 7 + (−7) = 0, and the additive inverse of −0.3 is 0.3, because −0.3 + 0.3 = 0. Similarly, the additive inverse of a − b is −(a − b) which can be simplified to b − a. The additive inverse of 2x − 3 is 3 − 2x, because 2x − 3 + 3 − 2x = 0.

It will take 4.63 years to double the principal.

The formula for calculating the amount (A) on a principal (P) invested at the rate of r%, compounded continuously after t years is-

A = P[tex]e^{rt}[/tex]

Here r = 6.5%

= 0.065

Let the principal amount be P,

then the amount after t years = 2P

A = P[tex]e^{rt}[/tex]

2P = P[tex]e^{rt}[/tex]

2P/P = [tex]e^{rt}[/tex]

2 = [tex]e^{0.065t}[/tex]

Taking log on both sides-

Log 2 = log [tex]e^{0.065t}[/tex]

Log 2 = 0.065t log e

Log 2 = 0.065t

0.65t = Log 2t
