Answer:
a) The interval for those who want to go out earlier is between 43.008 and 46.592
b) The interval for those who want to go out later is between 47.9232 and 51.9168
Step-by-step explanation:
Given that:
Sample size (n) =128,
Margin of error (e) = ±4% =
a) The probability of those who wanted to get out earlier (p) = 35% = 0.35
The mean of the distribution (μ) = np = 128 * 0.35 = 44.8
The margin of error = ± 4% of 448 = 0.04 × 44.8 = ± 1.792
The interval = μ ± e = 44.8 ± 1.792 = (43.008, 46.592)
b) The probability of those who wanted to start school get out later (p) = 39% = 0.39
The mean of the distribution (μ) = np = 128 * 0.39 = 49.92
The margin of error = ± 4% of 448 = 0.04 × 49.92 = ± 1.9968
The interval = μ ± e = 44.8 ± 1.792 = (47.9232, 51.9168)
The way for those who want to go out earlier to win if the vote is counted is if those who do not have any opinion vote that they want to go earlier
Answer:
0.75d
Step-by-step explanation:
<u>Step 1: Convert words into an expression</u>
At one particular store, the sale price, s, is always 75% of the display price, d
d is the display price
%75 they are always off
d*%75
d * 0.75
<em>0.75d</em>

Answer: 0.75d
Answer:
1.932 days (or approximatelly 1 day, 22 hours and 22 minutes)
Step-by-step explanation:
The inicial concentration is 60,000, and this concentration triples every 4 days, so we can write the equation:
P = Po * r^t
where P is the final concentration after t periods of 4 days, Po is the inicial concentration and r is the ratio that the concentration increases (r = 3)
Then, we have that:
102000 = 60000 * 3^t
3^t = 102/60 = 1.7
log(3^t) = log(1.7)
t*log(3) = log(1.7)
t = log(1.7)/log(3) = 0.483
so the number of days that will take is 4*0.483 = 1.932 days (or approximatelly 1 day, 22 hours and 22 minutes)
Bit: Computers deal with binary digits, or bits for short. A bit can be 0 or 1, equivalent or off or on.
Byte: One byte is eight binary digits, such as 1111001.
Kilobyte (KB): The smallest file stored on a smartphone, tablet or PC is typically four kilobytes (4KB) in size. A kilobyte is 1024 bytes. Therefore 1KB is the same as 1024 x 8 = 8192 binary digits.
Megabyte (MB): 1024KB equals one megabyte (MB).
Gigabyte (GB): There are 1024MB in one gigabyte.
Terabyte (TB): There are 1024GB in one terabyte (TB)
