What is the distance between the points(22,27) and (2,-10) ? Necessary round your answer to two decimal places

1 answer:

5 0

Distance formula : sqrt (x2 - x1)^2 + (y2 - y1)^2
(2,-10)....x1 = 2 and y1 = -10
(22,27)....x2 = 22 and y2 = 27
now we sub
d = sqrt ((22 - 2)^2 + (27 - (-10)^2)
d = sqrt ((20^2) + (37^2))
d = sqrt (400 + 1369)
d = sqrt 1769
d = 42.059 rounds to 42.06 <==

For these questions find the probability of drawing the given cards at random from a standard 52-card deck under each condition:

never [62]

Answer:

a) 6.37%

b) 6.25%

a) 0.60 %

b) 0.59 %

Step-by-step explanation:

2 )

a) With replacement

Probability of extracting a club is 13/52

Probability of extracting a spade is 13/51

13/52 * 13/51

= 6.37 %

b) Without replacement

13/52 * 13/52

= 6.25 %

3) With replacement

Probability of extracting a ace is 4/52

Probability of extracting a queen is 4/51

4/52 * 4/51

= 0.60 %

b) Without replacement

4/52 * 4/52

= 0.59 %

Work out an estimate for square root 1.13 + 2.84 x 9.33

Feliz [49]

hi there!

 $\large \rm = \color{brown} 27.6272 \: \\ \tt in \: \: alternate \: \: form \\ \\ \large \tt \color{cyan} \frac{17267}{625} , \color{red}27 \frac{392}{625}$ 

<h2 />

Step-by-step explanation:

 $\tt1.13 + 2.84 \times 9.33$ 

multiply the number

 $\tt \color{green}1.13 + 26.4972$ 

add the number

 $= \tt \color{green}27.6272 \\ \\ \tt \color{pink}or \: \: in \: \: alternate \: \: form \\ \\ \tt \color{purple} \frac{17267}{625} \tt \color{blue} \: , \: 27 \frac{392}{625}$
