Data

speed = 12 mph

time = 2 hours

distance = ?

Process

speed = distance / time

-Solve for distance

distance = speed x time

-Substitution

distance = 12 x 2

-Result

Answer:

Step-by-step explanation:

From the given information;

The total number of ways to choose 7 number = $^{40}C_7$

Number of ways to choose 7 correct numbers = $^{7}C_7$

∴

The probability P( win $2500000) is;

$= \dfrac{^{7}C_7}{^{40}C_7}$

$= \dfrac{\dfrac{7!}{7!(7-7)!} }{\dfrac{40!}{7!(40-7)!}}$

$= \dfrac{1 }{\dfrac{40!}{7!(40-7)!}}$

$= \dfrac{1 }{\dfrac{40!}{7!(33)!}}$

$= \dfrac{1 }{18643560}$

= 5.36 × 10⁻⁸

The probability P( win $10000) is:

$= \dfrac{^7C_5 \times ^{33} C_2}{^{40}C_7}$

$= \dfrac{ \dfrac{7!}{5!(7-5)!} \times \dfrac{33!}{2!(33-2)!} }{ \dfrac{40!}{7!(40-7)!}}$

$= \dfrac{ \dfrac{7!}{5!(2)!} \times \dfrac{33!}{2!(31)!} }{ \dfrac{40!}{7!(33)!}}$

$= \dfrac{ 21 \times 528 }{ 18643560}$

$= \dfrac{ 11088 }{ 18643560}$

$=\dfrac{462}{776815}$

= 5.95 × 10⁻⁴

Answer:

4.2 km

Step-by-step explanation:

The altitude of the triangle can be found using the triangle area formula:

A = 1/2bh

22.7 km² = 1/2(10.8 km)h

h = (22.7 km²)/(5.4 km) ≈ 4.2037... km

The missing measurement is about 4.2 km.
