Answer:

26.4 m

Step-by-step explanation:

The sine of an angle is the ratio between the opposite side of the angle and the hypotenuse. Hence,

sin 40° = $\frac{opposite}{hypotenuse}$

= $\frac{17}{c}$

c = $\frac{17}{sin40}$

c = 26.4 m (3 sf)

Mashutka [201]

Answer:

Students liked to play football are 210 .

Step-by-step explanation:

Formlua

$Percentage = \frac{Part\ value\times 100}{Total\ value}$

As given

In a school, 42% of the students liked to play football and 24% liked to play tennis.

As the percentage is always 100% .

Percentage of students choose swimming = ( 100 - 42 - 24) %

= (100 - 66) %

= 34 %

The rest of the students choose swimming If 170 students choose swimming .

Part value = 170

Percentage = 34 %

Putting all the values in the formula

$34 = \frac{170\times 100}{Total\ value}$

$Total\ value = \frac{17000}{34}$

Total value = 500

As the percentage for students liked to play football = 42%

Putting in the formula

$42 = \frac{Part\ value\times 100}{500}$

$Part\ value= \frac{42\times 500}{100}$

$Part\ value= \frac{21000}{100}$

Part value = 210

Thus

Students liked to play football = 210

Therefore the students liked to play football are 210 .

In a lottery game, a player picks 5 numbers from 1 to 46. If 4 of the 5 numbers match those drawn, the player wins second prize.

Umnica [9.8K]

Answer:

Step-by-step explanation:

given that in a lottery game, a player picks 5 numbers from 1 to 46

If 4 of the 5 numbers match those drawn, the player wins second prize.

Assuming the numbers are chosen without repitition we find that the player can choose 5 numbers in 46C5 ways.

To win the prize he must choose 4 numbers form the 5 numbers in the prize and remaining 1 number any other number.

i.e. no of ways to get II price = choosing 4 numbers out of 5, and one number from 41

= $5C4*41C1 = 205$

Probability of winning this prize

= $\frac{205}{46C5} \\= \frac{205*5(4)(3)(2)1}{46*45*44*43*42} \\=\frac{41*5*2*3}{46*9*22*43*21} \\=\frac{205}{1370754}$
