Greetings!

Decreases by 5

Step-by-step explanation:

To find the gradient ( or slope ), this finds out how the graph is decreasing or increasing, this can be done by using the following formula:

$\frac{y_{2} - y_{1} }{x_{2} - x_{1} }$

Where x1 and y1 are in the same coordinate set, plug the values in:

$\frac{45 - 20}{0 - 5}$

$\frac{25}{-5}$

= -5

So every hour it decreases by 5.

Hope this helps!

The minimum score required for an A grade is 83.

Step-by-step explanation:

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.

Mean of 72.3 and a standard deviation of 8.

This means that $\mu = 72.3, \sigma = 8$
