Answer:

£121

Step-by-step explanation:

5/12 of the total coins = 5/12 x 96 = 40   ⇒   40 coins are £2 coins

26 of the coins are £1 coins

Number of 50p coins = 96 - 40 - 26 = 30  ⇒  30 of the coins are 50p coins

Total money collected = 40 x £2 + 26 x £1 + 30 x £0.50 = £121

(rememberinf to convert 50p into £s)

Subtract 100 from each side.
25x = 600

Divide by 25.
x = 24

topjm [15]

Answer:

0.71%

Step-by-step explanation:

Given that a normally distributed set of data has a mean of 102 and a standard deviation of 20.

Let X be the random variable

Then X is N(102, 20)

We can convert this into standard Z score by

z=\frac{x-102}{20}

We are to find the probability and after wards percentage of scores in the data set expected to be below a score of 151.

First let us find out probability using std normal table

P(X<151) = P(Z

We can convert this into percent as muliplying by 100

percent of scores in the data set expected to be below a score of 151.

=0.71%
