Answer:C
Step-by-step explanation:
The correct answer is c. To carry out this calculation, we begin by describing the sampling distribution of the sample proportion. The sample size is n=50 and the population proportion of teachers who made an apparel purchase is .56. Shape: because np=(50)(.56)=28 and n(1-p)=(50)(.44) are both at least 10, the shape of the sampling distribution of the population proportion is approximately normal. Center: p=.56. Variability: the standard deviation of the sample proportion is approximately .0702. normalcdf(loser: .6, upper: 1000, mean: .56, SD: .0702)=.284.
The correct equation would be: 2.) 0.05(x+4) + 0.10x = $1.25
A nickel is worth 5 cents. A dime is worth 10 cents.
no. of nickels = x + 4
no. of dimes = x
nickels + dimes = 1.25
0.05(x + 4) + 0.10x = 1.25
0.05x + 0.20 + 0.10x = 1.25
0.15x = 1.25 - 0.20
0.15x = 1.05
0.15x/ 0.15 = 1.05 / 0.15
x = 7 *no. of dimes.
no. of nickels = x + 4 = 7 + 4 = 11
To check:
0.05(11) + 0.10(7) = 1.25
0.55 + 0.70 = 1.25
1.25 = 1.25
You need to know sum of inner angles of a triangle. Then you can write the equation relating with X
Well, I don't see a chart but I will try! If your shape was a square then one of your side lengths would be 10. If it was a a rectangle then your base and height would be 10 and 10. If it was a triangle then your base could be 10 and your height would be 20. If it was a parallelogram then your base and height would be 10. It it was a trapezoid then your first base would 8 and the other base would be 12 and your height would be 10. Lastly, if your shape was a circle then your radius would be 10. I am sorry if I did not answer your question but I hope this helps! Have good day!
