<span>There are 3 several ways to place an order for 5 items, like for example all or 5 tricycles, the number of wheels that will be needed is 15 wheels, for 5 order of wagons, the number of wheels that will be needed is 20 wheels, then lastly the 5 order combinations like 3 tricycles and 2 wagons the number of wheels that will be needed are 17 wheels.</span>
The size of the sample they should take to estimate p with a 2% margin of error and 90% confidence is n = 1691.
In statistics, the margin of error is just the degree of a significant error in the outcomes of random sample surveys.
The formula of margin error is, E = z√((p-vector)(1 - (p-vector)) ÷ n)
E = 2% = 0.02
Confidence level = 90%
Now, the proportion is not given so adopt nominal (p-vector) = 0.05
The critical value at CL of 90% is 1.645.
Thus, making n the subject,
n = z²(((p-vector) × (1 - (p-vector))) ÷ E²)
n = 1.645²((0.5 × 0.5) ÷ 0.02²)
n = 1691.266
n ≈ 1691

I hated probability in middle school. I'm not 100% sure but I would go with the 3rd answer choice, 3/100.
Answer:
It would be the side opposite the smallest angle.
Side DE (which is opposite angle F) is the shortest.
Step-by-step explanation:
Answer:
Mikaya and Olivia are correct to be suspicious
Step-by-step explanation:
Sum of the angles of a triangle is always 180
But, The sum of all angles of the triangle that Zuri solved = 93 + 63 + 36 = 192 ≠ 180
So, Zuri is wrong
