Answer:

Step-by-step explanation:

The area of a trapezoid is the average of the parallel bases times the height.

A=h(a+b)/2 and since we have two identical trapezoids the total are will be

A=h(a+b) in this case

A=15(32+25)=855mm^2

Find the mean and standard deviation. Show all work. 1. X 0 1 2 3 4 P(x) .07 .38 .22 .13

Paraphin [41]

Answer:

Mean = 2.14

Standard deviation = 2.40

Step-by-step explanation:

The calculation of mean and standard deviation is shown below:-

$X = .07\times0 + 0.20\times 1 + 0.38\times 2 + 0.22\times 3 + 0.13\times 4\\\\ = 0 + 0.2 + 0.76 + 0.66 + 0.52$

= 2.14

So, the mean is 2.14

Now, For computing the standard deviation first we need to find out the variance which is shown below:-

Variance is

$Var(X) = P(X^2) - [P(X)]^2\\\\ P(X^2) = .07\times (0^2) + .20\times (0^1) + .38\times (0^2) + .22\times (0^3) +0.13\times (0^4)$

After solving the above equation we will get

= 5.78

Now, the standard deviation is $= \sqrt{Variance}$

$= \sqrt{5.78}$

= 2.404163056

= 2.40

Live Fund are selling their holding at $5,000 per share. How much would Live Fun receive if they sold half thier holding in Mark

Brums [2.3K]

Live Fund receive $\bold{\$2500 N}$ it they sold half thier holding in Marks Brothers.

<u>Solution:</u>

Given: Sale price of Live Fund holding is 5000 dollar

To find: Amount that Live Fund will get if they sell half of their holding in Marks Brothers.

Assume the total holdings held by Live Fund in Marks Brothers as N

Therfore, half the number of shares or (half the holdings) of Live Fund will be $\frac{N}{2}$ .

Thus, if each share is valued at $\$5000$ , then the total value of the number of shares sold will be as follows,

$\Rightarrow5000\times\frac{N}{2}\text{ dollars }\rightarrow\frac{5000\times N}{2}\text{ dollars }$

$\Rightarrow2500 N\text{ dollars }$

Hence, Live Fund will receive $\$2500 N$

One-fourth of the cars that an automobile manufacturer produces are sports cars, and the rest are sedans. If one-fifth of the ca

Mashcka [7]

Answer:

Step-by-step explanation:

Let's base this on 100%, or 100 cars, which is 100% of the cars. If 1/4 of the 100 cars are sports cars, then we have

25 sports cars and

75 sedans

If 1/5 of the total cars are red, 20 of the 100 cars are red (since 1/5 is 20).

If 1/3 of the sports cars, of which we have 25, are red, then 25/3 of the sports cars are red.

Since we have 20 total red cars and 25/3 of them are sports cars, then the rest of them must be red sedans:

Total red cars - red sports cars = red sedans

$20-(\frac{1}{3}*25)$ which simplifies to

$20-\frac{25}{3}=\frac{60}{3}-\frac{25}{3}=\frac{35}{3}$
