Answer:

84 is 30% of 280

Step-by-step explanation:

Write and solve this equation:  84 = 0.30n, where n is the unknown number.

Then n = 84 / 0.30 = 280

84 is 30% of 280

In a study of automobile collision insurance costs, a random sample of n = 35 repair costs of front-end damage caused by hitting
laiz [17]

Answer: The maximum error = $105.76.

Step-by-step explanation:

Formula to find the maximum error:

E= z^*\dfrac{\sigma}{\sqrt{n}}

, where n= sample size.

\sigma = Population standard deviation

z*= Critical value(two-tailed).

As per given  , we have

\overline{x}=1438

n= 35

\sigma=269

For 98% confidence  , the significance level = 1-0.98=0.02

By z-table , the critical value (two -tailed) =z^* = z_{\alpha/2}=z_{0.01}=2.326

Now , the maximum error = E= (2.326)\dfrac{269}{\sqrt{35}}

E= (2.326)\dfrac{269}{5.9160797831}

E= (2.326)\times45.4692989044=105.761589252\pprox105.76

Hence, With 98% confidence level , the maximum error = $105.76.

Help meh pls!!!!!!!!!!!!!!!!!!!!!!! 11÷3/4
AVprozaik [17]

Answer:

Step-by-step explanation:

Multiply by the reciprocal of 3/4. That is 4/3

\frac{11}{1} *\frac{4}{3} =\frac{44}{3}

2 doesnt go into 44, but it does go into 42. It goes into 42 fourteen times. Then there is 2/3rds leftover

\frac{44}{3} ,14\frac{2}{3} are both equivalent
