Write a situation to represent the equation y = 0.5x.

The temperature change rate is determined by taking the temperature difference in °F and dividing it by the time measured in minutes. Thus,
rate of change in temperature = -25.5°F / 1.5 min
= -17°F / min
Therefore, the temperature decreases at a rate of -17°F every minute. 

Answer:

The repair of the stretch of road will require

weeks to finish.

Step-by-step explanation:

Provided:

Length of the roads needing repair =

Length of the road workers can fix in a week =

To ascertain how many weeks it will take to mend this road stretch.

Solution:

Worker's road repair rate =   per week.

Overall road length to repair =

The time required to repair

of road by the workers can be calculated: ⇒

When dividing mixed numbers, we change them first into fractions.

To compute fraction division, we take the reciprocal of the divisor and substitute division with multiplication:

⇒  

We revert the fraction back into a mixed number.

Thus, it will take

weeks to complete the road repair task.

The highest 5% of scores corresponds to the 95th percentile, meaning the cutoff score is defined as



When transformed into the standard normal distribution,



A cumulative probability of 95% corresponds to a z-score of approximately , indicating that the cutoff score is likely around

3x4-2x3-2x2+4x-10
