Answer:

BC^2=10^2+30^2

Step-by-step explanation:

P=10
B=30

Using pythagorean theorem

$\\ \sf\longmapsto BC^2=10^2+30^2$

$\\ \sf\longmapsto BC^2=100+300$

$\\ \sf\longmapsto BC^2=400$

$\\ \sf\longmapsto BC=\sqrt{400}$

$\\ \sf\longmapsto BC=20$

(3,5),
(5,8),
(6,13)
------
(14,26)/3

then use the point slope form of a line to find equation of line

 $y-y_1=m(x-x_1)
\\y - \frac{26}{3} = 2.5(x- \frac{14}{3})
\\y - \frac{26}{3} = \frac{5}{2} (x- \frac{14}{3})
\\y - \frac{26}{3} = \frac{5}{2} x- \frac{5}{2}\times\frac{14}{3}
\\y - \frac{26}{3} = \frac{5}{2} x- \frac{35}{3}
\\6y-52=15x-70
\\15x-6y-18=0$

Find y-intercept for x = 0.

 $15x-6y-18=0
\\15\times0-6y-18=0
\\-6y=18
\\y=-3$

An archer hits a bull’s-eye with a probability of 0.09, and the results of different attempts can be taken to be independent of

Answer: Variance = 0.858

Step-by-step explanation: The variance formulae for a probability distribution is given below as

Variance = √npq

Where n = number of times experiment was performed = 9

p = probability of success = 0.09

q = probability of failure = 1 - p = 1 - 0.09 =0.91

Variance = √9×0.09×0.91

Variance = √0.7371

Variance = 0.858
