Step-by-step explanation:
66.5 over 70 is the same as saying
66.5/70 which is
66.5 ÷ 70 = .95
Move the decimal 2 places to the right to convert to %
95%
Answer:
b) the mean will be off center in the boxplot and above the median
Step-by-step explanation:
First, we must inform that the median is not affected by outlier. Thus, there is possibility that a (some) student(s) score very high than others. This account for the reason why the mean value is higher than the median.
Since the mean is higher than the median, the score is skewed to the left! That is, majority of the students score low. Hence, we can say that the score is not exactly normal distributed.
NB:
Statistically the mean value given by the teacher is not significantly different from what the students obtained from the sample taken. This implies that, the sample is unbiased of the population mean as given by the teacher.
Answer:
Equation: 1.50x + 10 34
Amount of rides Dan can go on: 16 rides
Step-by-step explanation:
We can represent this situation using this equation:
1.50x + 10 34
The $10 Dan has to pay as admission is the fixed number because it doesn't vary and always remains the same, so no x goes next to 10.
Each ride costs $1.50 so this is the variable number as it changes with how many rides Dan goes on, therefore an x will go next to 1.50 to represent the amount of rides Dan goes on.
Lastly, Dan has $34 to spare, so the amount spent has to be less than or equal 34.
Solve the equation for x to find the greatest amount of rides Dan can go on:
1.50x + 10 34 Subtract 10 from 34
1.50x 24 Divide 24 by 1.50
x 16
So, Dan has enough money to go on 16 rides or less.
Let's check this answer:
1.50(16) + 10 34 Multiply 1.50 by 16
24 + 10 34 Add 24 and 10
34 34
