Hello there,
To find the perimeter you add up all 4 sides of the card. The two measurements are 16 and 25 however, this also the case for the other two sides as the card is a perfect rectangle or square.
So 16+16+25+25= 82
The perimeter is 82 cm
Hope this helps!
Answer:
-10,-6,-4,3,7
Step-by-step explanation:
This is because -10 is less than -6,-6 is less than -4,-4 is less than 3 and followed by 7 and vice versa for descending other
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.
Step-by-step explanation:
Let X = the number of days.
For growth rate,
y = X° × rate of growth, k
Where,
X° = initial amount of bacteria
k = rate of growth per day
Colby = 50 bacteria
kc = 2^(24/2 × X)
y = 50 × 2^(12X)
Jaquan = 80 bacteria
kj = 2^(24/3 × X)
y = 80 × 2^(8X)
