Answer:
$4.16
Step-by-step explanation:
To solve this problem, we need to find 15% of $27.70. To do that, we just multiply 27.70 by the decimal form of 15%.
First, change 15% into a decimal:
15 -> -> 0.15
Now, lets multiply:
Jonathan should leave a tip of $4.16
Answer:
6. 19 candles
7. 6 pills
Step-by-step explanation:
6. If a particular candle burns for 2 3/4 hours (=2.75) and you want to use similar candles to burn one at a time over 10 days for 5 hours each day, find the total number of hours: 10 x 5 = 50 hours. Then, divide by the amount of time it takes for one candle to burn: 10÷2.75 = 18.18. Since the answer is a decimal, you will need to round to the next whole number = 19 candles.
7. Given the rules that no more than three pills may be taken in a four-hour period and each pill must be taken 1 1/2 hours (=1.5) apart, you can take the total number of hours (10) and divide by the time between each pill (1.5):
10 ÷ 1.5 = 6.7
Since you won't take part of a pill, the most you can take is 6 and because the intervals are 1.5 hours, 1.5 + 1.5 + 1.5 = 4.5, you will not have taken more than 3 in any four hour period.
Answer:
The mean of the sampling distribution of p is 0.75
The standard deviation of the sampling distribution of p is 0.0274
Step-by-step explanation:
According to the given data 75% of the sampled households watch sports on television at least once a month therefore the mean of the sampling distribution of p is 0.75.
In order to calculate the standard deviation of the sampling distribution of p we would have to use the following formula as follows:
Standard deviation = √ [ p ( 1 - p) / n ]
= √[ 0.75 * ( 1 - 0.75) / 250]
= 0.0274
The standard deviation of the sampling distribution of p is 0.0274.
