Answer:

? = 45

Step-by-step explanation:

Since the triangles are similar, we can use proportions

20 20+8

------- = -------

? ? + 18

20 28

------- = -------

? ? + 18

Using cross products

20 ( ? +18) = = ? * 28

Distribute

20 ? + 360 = 28 ?

Subtract 20 ? from each side

360 = 8?

Divide each side by 8

360/8 = ?

45 = ?

Answer: $\dfrac{11}{87}$

Step-by-step explanation:

Given : An automobile manufacturing plant produced 30 vehicles today: 10 were sedans, 9 were vans, and 11 were trucks.

Number of combinations of n things taking r at a time :

$^nC_r=\dfrac{n!}{r!(n-r)!}$

Number of ways to choose two vehicles out of 30 vehicles :-

$^{30}C_2=\dfrac{30!}{2!(28)!}\\\\=\dfrac{30\times29}{2}\\\\=435$

Number of ways to choose two trucks out of 11 vehicles :-

$^{11}C_2=\dfrac{11!}{2!(9)!}\\\\=\dfrac{11\times10}{2}\\\\=55$

Now, the the probability that two trucks will be selected will be :-

$\dfrac{55}{435}=\dfrac{11}{87}$
