What is the distance between the points (-4, 2) and (3,-5)?

777dan777 [17]

Solution:
We are going to find the distance between points A -4; 2, B 3; -5 :
d = √ (xb - xa) 2 + (yb - ya) 2 =

= √ (3 - (-4)) 2 + (-5 - 2) 2 =

= √72 + (-7) 2 = √49 + 49 =
= √98
= 7√2 ≈ 9.899494936611665

A restaurant interest survey of 230 citizens in a town showed that 80 want a new Chili's, 120 want a new Red Lobster, and 20 wan

The right solution to the given question is " $\frac{2}{23}$ ", " $\frac{6}{23}$ " and " $\frac{5}{23}$ ".

According to the question,

$a+b+c+d = 230$
$b = 20$
$a+b = 80$

By putting the value of "b", we get

$a+20=80$

$a = 80-20$

$a = 60$

$b + c=120$

By putting the value of "b", we get

$20+c=120$

$c = 120-20$

$c = 100$

$d = 230-60-100-20$

By putting the values of "a", "b", "c" and "d", we get

$d = 50$

(a)

P(both Chili's and Red lobster),

= $\frac{b}{a+b+c+d}$

= $\frac{2}{23}$

(b)

P(only chili's),

= $\frac{a}{a+b+c+d}$

= $\frac{6}{23}$

(c)

P(neither),

= $\frac{d}{a+b+c+d}$

= $\frac{5}{23}$
