Cik Ain deposited RM5 000 at a bank with an interest rate of 4% per annum.
(a) Calculate the total savings of Cik Ain after she has saved for 1 year.​

Answers

Answer: RM 5200

Step-by-step explanation:

Principal = RM5000

Rate = 4%

Time = 1 year

Simple Interest = PRT

= 5000 × 4% × 1

= 5000 × 0.04 × 1

= 200

Now, the total savings will be the addition of the principal and the interest which will be:

= RM 5000 + RM 200

= RM 5200

Tiana solved the problem below and found that there was no solution. Solve the problem. Do you agree with her answer? Show your work to support your answer either way. -6(x - 4) + 4x = -2x + 18

Note: explain it well enough so I could borrow your answers

Answers

Answer:

Step 1: Simplify both sides of the equation.

−6(x−4)+4x=−2x+18

(−6)(x)+(−6)(−4)+4x=−2x+18(Distribute)

−6x+24+4x=−2x+18

(−6x+4x)+(24)=−2x+18(Combine Like Terms)

−2x+24=−2x+18

−2x+24=−2x+18

Step 2: Add 2x to both sides.

−2x+24+2x=−2x+18+2x

24=18

Step 3: Subtract 24 from both sides.

24−24=18−24

0=−6

Why might Razis method not be a good way to estimate the probability? My team won 18 of their last 20 matches, so the probability that they will win their next match is 18/20 = 90%

Answers

Answer:

It is a really idealistic way to estimate probability.

It usually works well for random events where there is no restriction like:

"There are N elements in a set, the probability of randomly selecting any element is the same (so there is no restriction) meaning that for every single element, the probability is 1/N.

Now suppose that there are K elements (K < N) with a given characteristic, then the probability of randomly selecting one of the K elements out of the sett with N elements is equal to K times the probability of each element, this is:

P = K*(1/N) = K/N"

Then if a dice has 6 possible outputs, and we want to find the probability of getting a 3 or a 5, we need to find the quotient between the outcomes where we get a 3 or a 5 (2) and the total number of outcomes (6)

P = 2/6

Now let's go to the case in the problem:

We know that out of the last 20 games, your team won 18.

Then yes, your team won (18/20)*100% = 90% of their played games.

Does this mean tath the probability of winning the next game is 90%?

Well no, because this is not a random selection, there are a lot of other things needed to analyze, as the win rate of the other team (suppose that the other team won 14 of their last 20 games, then their win rate is (16/20)*100% = 70%

Does this mean that the probability where our team wins is 90%, and the probability of the enemy team winning is 70%?

Well no, this makes no sense at all, and this is why this method is not a good way to estimate probability in complex cases like this one.

Claire is building a dollhouse where 11 inch on the plans is equivalent to 55 inches on the actual dollhouse. ​ Scale Factor ​If the house is to be 32.532.5 inches tall, what will the height be on the plans? ___________ inches

Answers

Answer:

1 : 5 ;

6.5 inches

Step-by-step explanation:

Given that:

11 inch on plan = 55 in actual

The scale factor here is :

11 : 55

1 : 5 ( 1 inch on plan represents 5 inches the actual house)

If the house is 32.5 inches tall

The height in inches of the house on the plan will be:

Actual Height of house / 5

32.5 / 5 = 6.5 inches

Answer: 6.5

Step-by-step explanation:

65 traffic cones we’re equally spaced over 5/8 of a mile how many traffic cones are used per mile

Answers

Given:

65 traffic cones we’re equally spaced over [tex]\dfrac{5}{8}[/tex] of a mile.

To find:

The number of traffic cones are used per mile.

Solution:

We have,

Number of cones used in [tex]\dfrac{5}{8}[/tex] of a mile = 65

Number of cones used for a mile = [tex]65\times \dfrac{8}{5}[/tex]

                                                       = [tex]13\times 8[/tex]

                                                       = [tex]104[/tex]

Therefore, 104 traffic cones are used per mile.

The distance is
meters

Answers

Answer:

2232.48 meters

Step-by-step explanation:

From the diagram:

Radius of semicircle = 74

Length of straightway on each side = 1000

The length of school track:

Straightway on each side = 2 * 1000 m = 2000m

Length of semicircle = πr/2

Length of both semicircle  = 2 * 3.142 * 74 /2 = 232.47785

Total Length = ( 2000 + 232.47785) = 2232.48 meters

Find two positive consecutive integers such that the square of the first added to three times the second is 24

Answers

Answer:

3 and 5

Step-by-step explanation:

Let the two consecutive odd integers be x and x + 2.

Now,

The given statement is

[tex]x^2 + 3 \times (x+2)=24\\x^2 + 3x+6-24 = 0 \\x^2 + 3x-18 = 0\\x^2+6x-3x-18=0\\x(x+6)-3(x+6)=0\\(x-3)(x+6)=0\\x=3,-6[/tex]

Taking x=3.

Hence, two consecutive odd integers are 3 and 5.

A trapezoid has an area of 18 square miles. The bases are 5 miles and 7 miles. Using these measurements, the height of this trapezoid is how many miles

Answers

Answer:

3 miles

Step-by-step explanation:

A trapezoid has an area of 18 square miles. The bases are 5 miles and 7 miles. Using these measurements, the height of this trapezoid is how many miles

Area of a trapezoid = 1/2 (a + b)h

The formula for the height of a trapezoid =

h = 2(A/a + b)

A = 18 square miles

a = 5 miles

b = 7 miles

h = 2(18/5 + 7)

h = 2( 18/12)

h = 2 ( 9/6)

h = 3 miles
