Given:
425 school children
Teacher : 80
Doctor : 105
Lawyer : 70
Police Officer : 70
Firefighter : 100
Total = 425
After applying Pearson's chi-squared test, it is concluded that this data reflects a real difference in the population.
Answer:
45158
Step-by-step explanation:
Since the colony grows at a rate of 12%, after 2 years there will be
bacteria. Since you probably can't have part of a bacteria, you round to 45158.
Answer:
77
Step-by-step explanation:
Add the numbers together, then divide them to how much numbers are there.
74 + 75 + 80 + 76 + 75 + 81 + 78 = 539
Since there are 7 numbers, you divide 539 by 7.
539/7 = 77
Question 1:
A = w * l
A = 5432m^2
l = 97
A / l = w
5432 / 97 = 56
w = 56
Question 2:
Perimeter of rectangle = 2w + 2l
P = 336
w = 79
P - 2w = 2l
336 - 158 = 178
178 / 2 = 89
l = 89
