Answer:
9
Step-by-step explanation:
Distance between two points is given as;
Square root [(X2-x1) 2+ (y2-y1)2]
= (6-(-3))2 +(-4-(-4))2
=Square root (81 +0)
=9
Answer:
-3/2
Step-by-step explanation:
Given the funtion
(2x+3)² - 6x+9 = 0
(2x+3)² = 6x + 9
Expand
4x²+12x+9 = 6x + 9
4x²+12x - 6x = 0
4x²+6x = 0
4x² = -6x
4x = -6
x = -6/4
x = -3/2
Hence the value of x is -3/2
-12+2c=2*c-6:2*c-6=0. C-6=0 and c=6.

Let the length of rectangle be l
breadth be b
so ,
b+5 = l
perimeter = 2 × ( l+b) = 150
2b + 5 = 75
b = 35
so l = 40
Answer :
0.2322
Step-by-step explanation:
Proportion, p of those who used e - ticket to get boarding pass = 112 / 280 = 0.4
p = 0.4
1 - p = 1 - 0.4 = 0.6
Number of samples, n = 8
P(x = 4)
Using the binomial probability formula :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
P(x = 4) = 8C4 * 0.4^4 * 0.6^4
P(x = 4) = 70 * 0.0256 * 0.1296
P(x = 4) = 0.2322432
P(x = 4) = 0.2322
