The ratio 1:2 means there are twice as many dimes as there are quarters. An expression could be n=2d, n being number of quarters, d being number of dimes.
We can convert 7/10 to a decimal first.
7/10 = 0.7
Now we can multiply this problem easier.
35 x 0.7 = 24.5
Answer:
0.0062
Step-by-step explanation:
Let X be the diagnosed blood sugar level.
Probability of committing a Type II error = Probability of failing to detect the disease when the person has the disease = Probability that the diagnosed blood sugar level is less than or equal to 125 =

![= P[Z\le (125 - 150)/10]](https://tex.z-dn.net/?f=%3D%20P%5BZ%5Cle%20%28125%20-%20150%29%2F10%5D)
![=P[Z \le -2.5]](https://tex.z-dn.net/?f=%3DP%5BZ%20%5Cle%20-2.5%5D)
= 0.0062
