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
Answer:
B. (3, 0)
Step-by-step explanation:
The x-intercept signifies the location on the graph where it intersects the x-axis.
At the x-intercept, y=0 or f(x)=0.
Therefore, you need to examine the table for the instance where f(x)=0.
The value f(x)=0 is found at x=3 in the table.
We express this as an ordered pair.
Hence, the x-intercept is (3,0).
The right option is B.
Answer:
1. $14.88
2. $12.40
Step-by-step explanation:
Translated into English:
A company is responsible for transporting office cabinets over a distance of 425km. The charge is R $ 2.10 for each kilometer journeyed. If the cabinets are assembled, the vehicle can carry 60 units. When taken apart, the capacity expands by 6 times. We need to determine: 1- The cost for each assembled cabinet? 2- The savings achieved per cabinet when they are disassembled.
Solution:
For 425 km at R $2.10 per km:
425 * 2.10 = $892.50 total expenditure
For the 60 assembled cabinets, the cost for each is calculated as:
Cost per assembled cabinet = 892.5/60 = $14.875, rounding to $14.88
When disassembled, the capacity becomes:
60 * 6 = 360
The cost per cabinet is then:
892.5/360 = $2.48
The savings indicate how much is saved compared to assembled cabinets:
14.88 - 2.48 = $12.40
Savings = $12.40
You can utilize them in reverse order, but this method doesn't apply for subtraction.
