Step-by-step explanation:

9.\tt{\dfrac{20}{25}×100  }

\tt{\dfrac{20}{\cancel{25}}×\cancel{100}  }

\tt{80\%   }

80% students passed in test.

10.\tt{5\%=136\$   }

\tt{ 1\%=\dfrac{136}{5}  }$

Total income=100% =\tt{\dfrac{136}{5}×100  }

\tt{2720   }$

Find the slope of each line.
Crazy boy [7]

Answer:

The answer is -8

Step-by-step explanation:

Subtracting 8x from both sides to get Y by itself, you would get

Y= -8X + 10, and we know that y=mx+b, where M is the slope, therefore -8 is M and the slope is -8.

nignag [31]

Answer:

Answer = √(0.301 × 0.699 / 83) ≈ 0.050

A 68 percent confidence interval for the proportion of persons who work less than 40 hours per week is (0.251, 0.351), or equivalently (25.1%, 35.1%)

Step-by-step explanation:

√(0.301 × 0.699 / 83) ≈ 0.050

We have a large sample size of n = 83 respondents. Let p be the true proportion of persons who work less than 40 hours per week. A point estimate of p is  because about 30.1 percent of the sample work less than 40 hours per week. We can estimate the standard deviation of  as . A  confidence interval is given by , then, a 68% confidence interval is , i.e., , i.e., (0.251, 0.351).  is the value that satisfies that there is an area of 0.16 above this and under the standard normal curve.The standard error for a proportion is √(pq/n), where q=1−p.

Hope this answer helps you :)

Have a great day
