Answer:
1,560,000 mm²
Step-by-step explanation:
A= This would make shape A's area <u>480,000</u>.
B= This would make shape B's area <u>180,000</u>.
C= This would make shape C's area <u>300,000</u>.
D= 1000×600 This wouls make D's area <u>600,000</u>.
Now you add up all of the areas;
480,000+180,000+300,000+600,000= 1,560,000 mm²
Answer:
The answer is below
Step-by-step explanation:
Given that:
Mean (μ) = 1.93, standard deviation (σ) = 1.08 pounds, sample (n) = 62.
the mean weight of discarded plastic for all household is given by:
The standard deviation of discarded plastic for all household is given by:
The confidence (c) = 90% = 0.9
α = 1 - c = 1 - 0.9 = 0.1
α/2= 0.1/2 = 0.05
The z score of 0.05 corresponds to the z score of 0.45 (0.5 - 0.05) which is 1.645. i.e.
The margin of error (E) =
The confidence interval =
We are 90% confidence that the value is between 1,7044 and 2.1556
Answer:
21 hours
Step-by-step explanation:
First, multiply 18 by 27 to represent the painting. You should get 486.
Then, subtract 486 from 738. You should get 252
Lastly, divide 252÷12. You should get 21.
Hope this helped!
