3cm= 30mm
8cm= 80mm

c^2 = a^2 + b^2
= 30^2 + 80^2
= 7300
c= square root of 7300
= 85.44003745
= 85mm

Hope this helps!

Use the given data to find the minimum sample size required to estimate a population proportion or percentage. Margin of error:

Yakvenalex [24]

Answer: 112

Step-by-step explanation:

Given : Significance level : $\alpha=1-0.95=0.05$

Critical value: $z_{\alpha/2}=1.96$

Margin of error : E = 9%=0.09

The estimated proportion of caret : p =0.38

Now, the formula to find the sample size :-

$n=p(1-p)(\dfrac{z_{\alpha/2}}{E})^2$

i.e. $n=(0.38)(1-0.38)(\dfrac{1.96}{0.09})^2$

$=111.738390123\approx112$

Hence, the required minimum sample size = 112

g Suppose a movie starts at 5:00 p.m. and Lindsay, a customer who is always late, arrives at the movie theater at a random time

lord [1]

Answer:

We get the height of the uniform density curve:

$f_X(x)=0.022$

Step-by-step explanation:

We know that a movie starts at 5:00 p.m. and Lindsay, a customer who is always late, arrives at the movie theater at a random time between 5:10 p.m. and 5:55 p.m.

Therefore, we get a uniform distribution between 10 and 55 min.

$f_X(x)=\frac{1}{b-a}\\\\f_X(x)=\frac{1}{55-10}\\\\f_X(x)=\frac{1}{45}\\\\f_X(x)=0.022$

We get the height of the uniform density curve:

$f_X(x)=0.022$

Solve for y. 14y-6(y-3)=22

mario62 [17]

Answer:

y=0.5

Step-by-step explanation:

14y-6(y-3)=22

14y-6y+18=22

8y+18=22

8y=4

y=0.5

Then we check our work...

14(0.5)-6((0.5)-3)=22

7-6(-2.5)=22

7+15=22

7+15 does equal 22, so this solution is correct.
