Answer:

It took the cell phone 4.15 seconds to reach the ground

Step-by-step explanation:

The formula is $t=\frac{\sqrt{h}}{4}$ , where t is the time and h is the height

The height of that the cell phone dropped from it is 275 feet above the ground

∴ h = 275

- Substitute the value of h in the formula to find t

∵ $t=\frac{\sqrt{275}}{4}$

∴ $t=\frac{5}{4}\sqrt{11}$

- Change it to decimal

∴ t = 4.15 seconds to the nearest 2 decimal places

It took the cell phone 4.15 seconds to reach the ground

Answer:

The correct answer option is 43%.

Step-by-step explanation:

We are given that 70% of students have blue eyes, 45% have dark hair, and 30% have blue eyes and dark hair.

We are to find the probability of a student getting selected will have dark hair with blue eyes.

P(D|B) = P(D∩B) / P(B)

Substituting the given values in it to get:

P(D|B) = 0.3 / 0.7 = 0.428

Rounding it to the nearest whole percent we get:

0.428 × 100 = 42.8% ≈ 43%
