Rolling 7 or 11 on the first roll is a win probability of winning on 1st roll

1 answer:

5 0

1/6 plus 1/18, which equals to 2/9. Suppose we roll 4 on the first roll (the probability of rolling 4 is 1/12). On each successive roll the probability of rolling 7 is 1/6 and the probability of rolling 4 is 1/12.

[i.dk how this can help but if you got a 7 or 11 rolling on the first round you would probably win]

forsale [732]

Area = Width x Length
Area = 108
Square root of 108 = 10.4

108/ 9 = 12 ...12 is not 12 larger than 9
108/ 6 = 18 ...18 is 12 larger than 6

108 = 6 x 18

Width = 6
Length = 18

Answer:

a) Sale Price; Rs. 800 Discount rate: 20%

b) Sale Price; Rs. 4000 Discount rate: 20%

c) Sale Price; Rs. 6000 Discount rate: 35%

Step-by-step explanation:

1. Approach

In these problems, one is given a list of original prices and the amount of price taken off during a discount. One has to find the sale price and the rate of discount. The easiest way to find the sale price is to subtract the discount price from the original price. The general train of thought to do this can be found in the following formula:

$(original\ price)-(discount\ amount)=(sale\ price)$

One is also asked to find the rate of discount. Use the following proportion format to do so:

$\frac{discount\ amount}{original\ price}=\frac{percent}{100}$

Substitute each of the values in the given problem into the equation and solve for the price.

2. Part A

Original price: 1000

Discount: 200

1. Sale price

Formula
$(original\ price)-(discount\ amount)=(sale\ price)$
Substitute and solve,
$1000-200=(sale\ price)$

$\\800 = sale\ price$

2. Discount rate

Formula

$\frac{discount\ amount}{original\ price}=\frac{percent}{100}$

Substitute, simplify, and solve

$\frac{200}{1000}=\frac{percent}{100}$
$\frac{1}{5}=\frac{percent}{100}$

$(5)(percent)=1(100)$
$percent=20$

3. Part B

Original price: 5000

Discount: 1000

1. Sale price

Formula,
$(original\ price)-(discount\ amount)=(sale\ price)$
Substitute and solve
$5000-1000=(sale\ price)$
$4000=(sale\ price)$

2. Discount rate

Formula
$\frac{discount\ amount}{original\ price}=\frac{percent}{100}$
Substitute, simplify, and solve
$\frac{1000}{5000}=\frac{percent}{100}$
$\frac{1}{5}=\frac{percent}{100}$
$5(percent)=1(100)$

$percent=20$

4. Part C

Original price: 8000

Discount: 2000

1. Sale price

Formula
$(original\ price)-(discount\ amount)=(sale\ price)$
Substitute and solve
$8000-2000=(sale\ price)$
$6000=(sale\ price)$

2. Discount rate

Formula,
$\frac{discount}{amount}=\frac{percent}{100}$
Substitute, simplify and solve,
$\frac{2000}{8000}=\frac{percent}{100}$
$\frac{1}{4}=\frac{percent}{100}$
$4(percent)=1(100)$
$percent=25$

The measure of an angle is twenty-nine times the measure of a complementary angle. what is the measure of each angle?

Alborosie

Complementary angles add up to 90°

Let one of the angle be x.
The other angle is 29x.

x + 29x = 90
30x = 90
x = 3
29x = 29(3) = 87

Answer: The two angles are 3° and 87°
