$\\ \sf\longmapsto -4d-5=-1$

Cancel - from both sides

$\\ \sf\longmapsto -(4d+5)=-(1)$

$\\ \sf\longmapsto 4d+5=1$

$\\ \sf\longmapsto 4d=1-5$

$\\ \sf\longmapsto 4d=-4$

$\\ \sf\longmapsto d=\dfrac{-4}{4}$

$\\ \sf\longmapsto d=-1$

Answer:

C. 34.15 oz

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore 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 pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu= 33, \sigma = 0.7$
