Step-by-step explanation:
Given
- 0.4(3x - 2) + ← substitute x = 4 into the expression
= - 0.4(3(4) - 2) +
= - 0.4(12 - 2) +
= - 0.4(10) +
= - 4 + 4 = 0
Probability helps us to know the chances of an event occurring. The probability that the next customer will pay with cash as a percent to the nearest whole number is 64%.
<h3>What is Probability?</h3>Probability helps us to know the chances of an event occurring. The sum of all the probabilities of an event is always equal to 1. The formula for probability is given as,
Given that in the last week 71 customers paid cash, 4 customers used a debit card, and 36 customers used a credit card. Therefore, the total number of customers who came to the business last month is,
Total number of customers = 71 + 4 + 36 = 111
Now, the probability that the next customer will pay with cash is,
Probability
= Number of customers who pay with cash / Total number of customers
= 71 / 111
= 0.63963
To convert probability into percentage multiply it by 100%, therefore, the probability can be written as,
Probability = 0.63963 × 100%
= 63.963% ≈ 64%
Hence, the probability that the next customer will pay with cash as a percent to the nearest whole number is 64%.

Answer:
The change in the people attending per game is 14.7 times as great as the change in the number of lost games.
This mean every game is lost, 14.7 less people (as the slope is negative) attend the next game.
Step-by-step explanation:
To calculate the slope, we need to relate two points of the function.
The slope of the function
can be calculated as
We have the point (x=8, y=256) when it says 265 people attended the next game after the team lost 8 games.
The second point is (x=15, y=153) when it says 153 people attended the next game after the team lost 15 games.
We can write
