Answer:

So, $(a + b)^0=1$

Step-by-step explanation:

$(a + b)^0$

To evaluete this expression we apply exponential property

$x^0=1$

IF any expression has exponent 0 then the value is 1 always

for example, $3^0 =1$

$5^0=1$

$(x+2)^0=1$ because exponent is 0

So, $(a + b)^0=1$

Normal Probability Distribution

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

The mean weight was 3398 grams with a standard deviation of 892 grams.

This means that $\mu = 3398, \sigma = 892$
