Step-by-step explanation:
4.0 has 2 significant digits.
The zeros after a non zero number are significant.
Any non zero number is significant.
0.004 has 1 significant digit.
4000 has 4 significant digits.
In your case 4.0 × 10^3 there is an exception because it is in scientific notation. So there are 2 significant digits.
hope this makes sense.

The standard deviation of wait time is 13.8564.
The length of time patients must wait to see a doctor in a local clinic is uniformly distributed between 25 minutes and 73 minutes. We have to find the standard deviation of the wait time.
The square root of the variance of a random variable, sample, statistical population, data collection, or probability distribution is its standard deviation. The standard deviation in statistics is a measure of the degree of variation or dispersion in a set of values. A low standard deviation implies that the values are close to the set's mean, whereas a high standard deviation shows that the values are spread out over a larger range.
S² = (73 - 25)²/12
S² = (48)²/12
S² = 192
S = √192
S = 13.8564

1) write a linear system - let a = boxes of apples and b = boxes of bananas
a + b = 86
32a + 16b = 1968
2) solve - use substitution
a = 86 - b
32(86 - b) + 16b = 1968
2752 - 32b + 16b = 1968
-16b = -784
16b = 784
b = 49
a + 49 = 86
a = 37
37 boxes of apples and 49 boxes of bananas
