Answer:
area = 66.28 km²
Step-by-step explanation:
area = (8 x 2) + (11 x 4) + (3.14)(2²)(0.5) = 16 + 44 + 6.28 = 66.28 km²
Answer:
Solution given:
area of semi circle=½×π×r²=½π×2²=6.28km²
area of rectangle ABCD=L×b=3×4=12km²
area of rectangle EFGC=L×b=8×6=48km²
total area =6.28+12+48=66.28 square kilometers.

A large home improvement store is considering expanding its selection of moving products, such as cardboard boxes and packing tape. The store constructs a 90% confidence interval to estimate the proportion of all customers who have moved houses at least once in the last five years. In the random sample of 620 customers, 201 (32.4%) replied that they had moved at least once in the last five years. The sample yielded the 90% confidence interval (0.293, 0.355) for the proportion of all customers who have moved in the past five years. What is the correct interpretation of this confidence interval
Answers
The correct interpretation of the confidence interval is 90% confidence that the true proportion of all customers who have moved in the past five years is between 0.293 and 0.355.
The confidence interval is also not a guarantee that the true proportion is between 0.293 and 0.355. It is simply a statement of our confidence that the interval contains the true proportion.
This means that if the study were repeated many times, and constructed a 90% confidence interval each time, then 90% of the intervals would contain the true proportion.
In this case, the sample proportion is 0.324, which is within the confidence interval. This means that the sample data is consistent with the confidence interval. However, the sample proportion could be outside of the confidence interval if we had a different sample.

pls help i need the answer
Answers
Answer:
137
Step-by-step explanation:
Use the formula for exponential growth:
f(x) = a(1 + r)^x
In this formula, f(x) is the resulting number, in this case the number of fast food stores. a is the initial value, in this case 50. r is the growth rate, which they told you was 7%. And x is the number of time intervals, which is how many years between 1990 and 2005.
Substitute the known values into the equation:
f(x) = a(1 + r)^x
r is going to be 0.07 because the growth rate in the equation is the decimal form of 7%. x will be 15 because 2005-1990 = 15
f(x) = 50(1 + 0.07)^15
f(x) = 50(1.07)^15
Now just solve.
f(x) = 50(1.07)^15
First raise 1.07 to the 15th power.
f(x) = 50(2.75903154)
Then simplify.
f(x) = 137.951577
They want the approximate amount, so round it down to 137. The number actually rounds to 138, but he doesn't have a full 138 stores, so you use 137.

There are 6 sides to a cube. So if you have the area of 1 side, you need only multiply by 6 to get the area of the cube
