Answer:
Divide £700 in the ratio 5:3:2.
The total number of 'parts' in this ratio
= 5 + 3 + 2 = 10.
So, to work out how much of the total corresponds to 1 part, we need to divide the total sum by the total number of parts: 700/10 = £70.
Now, we can multiply the amount we know for 1 part by each value in the ratio.
Step-by-step explanation:
70 × 5 = £ 350
70 × 3 = £ 210
70 × 2 = £ 140
The probability of making his 4th attempt is 0.77, since the probability of each attempt is independent.
The probability of making a field goal over 40 yards is 77%
Since the probability of making a field goal is independent, then the probability of succeeding in his 4th attempt does not depend on his previous attempts.
Hence, the probability of making his fourth attempt is the probability of making a field goal over 40 yards in each attempt which is 77% = 0.77
Hence, the probability of making it is 0.77

<h3>Answer:</h3>
- 28/100 = 7/25
- 100/28 = 25/7
<h3>Explanation:</h3>
The wording "the ratio of A to B" means A/B.
Here, "the ratio of the weight of silicon to the weight of crust" means ...
... (28 tons)/(100 tons)
Canceling common factors (and common units), this is ...
... 28/100 = 7/25
___
Then "the ratio of the weight of crust to the weight of silicon" means ...
... (100 tons)/(28 tons) = 100/28 = 25/7
