Answer:
25
Step-by-step explanation:
If all 70 were nickels, the value would be $3.50 Since that is 2.25 less, that means it needs 45 more 5 cents. Therefore, you would replace 5 of the nickels with dimes. This means there are 25 nickels and 45 dimes.

Answer:
The probability is 0.00478224
Step-by-step explanation:
Probability of scoring an attempt is 0.82
Probability of not is 1-0.82 = 0.18
So making the first point in attempt number 4 means that she failed the first three
So we have the probability as;
0.18 * 0.18 * 0.18 * 0.82 = 0.00478224
