Answer
Find out the how much did they win in total .
To prove
As given
Peter and angad win some money and share it in the ratio 4:1 .
Peter gets £28 .
Let us assume that x be the scalar multiple of the Peter and angad wins money.
Than
Peters money = 4x
Angad money = x
Than the equation
4x = 28
x = 7
Thus
Angad money = x
= £7
The total money peter and angad wins = Peters wins + angad win
= £28 + £7
= £35
Therefore the total cost of the peter and angad wins be £35.
.15 × 30.00 = 4.50
30.00 - 4.50 = 25.50
$25.50 is the sale price. I rounded 29.99 to 30.00

Step-by-step explanation:
Answer: The probability in (b) has higher probability than the probability in (a).
Explanation:
Since we're computing for the probability of the sample mean, we consider the z-score and the standard deviation of the sampling distribution. Recall that the standard deviation of the sampling distribution approximately the quotient of the population standard deviation and the square root of the sample size.
So, if the sample size higher, the standard deviation of the sampling distribution is lower. Since the sample size in (b) is higher, the standard deviation of the sampling distribution in (b) is lower.
Moreover, since the mean of the sampling distribution is the same as the population mean, the lower the standard deviation, the wider the range of z-scores. Because the standard deviation in (b) is lower, it has a wider range of z-scores.
Note that in a normal distribution, if the probability has wider range of z-scores, it has a higher probability. Therefore, the probability in (b) has higher probability than the probability in (a) because it has wider range of z-scores than the probability in (a).
