A coin is tossed 20 times. The outcomes H (for heads) and T (for tails) are recorded:
lina2011 [118]
After all 20 tosses of the coin, a tail was recorded 11 times. We can write this as 11/20.

To convert this into a decimal, we simply multiply the numerator and denominator by 5 so that the fraction is out of 100, giving us 55/100.
When we do the sum of 55 ÷ 100, we get the answer of 0.55.

I hope this helps!

A local company has K2,500 to set up an annuity to be paid quarterly for 5 years. The payments of that annuity are to be increas
Anvisha [2.4K]

Answer:

Step-by-step explanation:

(a).

Within 1 year, there would be 4 payments to be made.

therefore, PMT= \frac{P(1+i)}{n} = \frac{2500(1+0.025)}{4*5} =\frac{2562.5}{20} = $128.125

(i) 1st payment will be :PMT $128.125

(ii) 2nd payment will be :128.125*(1.025)^1= $131.33

(iii) 3rd payment will be :128.125*(1.025)^2=$134.61

(iv) 4th payment will be :128.125*(1.025)^3=$137.98

Hence the payments are: $128.125, $131.33, $134.61, and $137.98.

(b).

The size of the final payment PMT(1+i)^{m-1} where m 4 *5= 20

=128.125(1+0.025)^{20-1} \\=128.125(1.025)^{19} \\=$204.83

Find the value of x. Give reasons to justify your solution-
weqwewe [10]

Answer:

x =27

and total angl on D =180

so, 2x +2x+72=180

4x = 180 -72

4x = 108 (divied both sides by 4)

x= 27

Triangle DIG is reflected across the l-axis.
drek231 [11]

there is not such thing as an I axis, but I will show you what happens for both x and y axis so you can fill out the assignment with the correct information.

IF you meant flipping over the x axis, then the dot will go from top to bottom, bottom to up, the x position won't change only its height(y position)

This meant that for reflecting across the x axis, (x,y)->(x,-y)

For y axis its the opposite, just flipping to the side.

This meant that for reflecting across the y axis, (x,y)->(-x,y)
