Multiply .30 and 50 ... which is 15
Answer:
0.5578
Step-by-step explanation:
Fingerprint correctly match 92 % of the time.
A novice that will correctly identify a match 75% the time.
Each of the attempts of matching a fingerprint with the individual is independent.
The number of pairs are 7.
a). So the probability that the expert will identify every pair correctly is
= 0.92 x 0.92 x 0.92 x 0.92 x 0.92 x 0.92 x 0.92= 0.927 = 0.5578
Answer: 10
Step-by-step explanation: 2,000 divided by 200 is 10.
Answer:
-0.4
Step-by-step explanation:
If using a number line, start at 0.2 and go backwards 0.6 to get to -0.4
Since 12 is 8 x 1 1/2 she needs 1 1/2 time as much fruit.
1 1/2 x 10 = 15 strawberries and 1 1/2 x 4 = 6 oranges.
You could also solve this using proportions:

Cross multiply and get 8n= 120 divide by 8 and get 15 strawberries
Do the same for the oranges:

You can see that 4/8 = 1/2 so n/12 has to be 6 to be 1/2 (or solve it using cross products like I did above).
