Answer:
81 / 1024
Step-by-step explanation:
Given that :
Wheel is divided into 4:
Hence, probability of winning either 10%, 20%, 30% or 50% = 1/4
Probability of winning 50% discount = 1/4
Probability of not winning 50% discount :
1 - 1/4 = (4 - 1) /4 = 3/4
Hence, probability that 50% is won by 5th customer :
(3/4) * (3/4) * (3/4) * (3/4) * (1/4)
= (3/4)^4 * (1/4)
= (81 /256) *(1/4)
= 81 / 1024
3z + 6
3z and 6 has greatest common factor, that is 3. Divide 3z and 6 by the greatest common factor (3).
3z ÷ 3 = z
6 ÷ 3 = 2
So, we could work on the expression as following.
3z + 6
= 3 × z + 3 × 2
From the expression above, we should separate 3 from z and 2 by a parenthesis to make distributive property.
3 × z + 3 × 2
= 3(z + 2)
SUMMARY
3z + 6
= 3 × z + 3 × 2
= 3(z + 2)
First, we already have 64°. We take out the remaining 0.32°.
The conversion factors necessary to answer this item are,
1° = 60'
1' = 60''
number of minutes = (0.32°)(60' / 1°) = 19.2'
We already have 19' and 0.2'.
number of seconds = 0.2' x (60'' / 1') = 12''
<em>Thus, the answer is 64°19'12''. </em>
Okay. To solve this problem, all we have to do is find the amount of change by subtraction. 50 - 30 = 20. You find the percent of change by writing out a proportion. Do change/original = x/100. You set it up like this to find the percentage. With the numbers plugged in, it’s 20/30 = x/100. Cross multiply in order to get 2,000 = 30x. Now, divide each side by 30 to isolate the “x”. 2,000/ 30 is 66.6666 and the 6ms repeating or 67 when rounded to the nearest whole number. The percent markup is approx. 67%.
