Answer:

Step-by-step explanation:

15^2 = 225 (memorize everything to 20, thank me later)

39^2 = 1521 (just use a calculator for everything higher)

225 + 1521

1521 =?= 45^2

45^2 = 2025

1521 =/= 2025

Just to be sure, I'll do 15^2 + 45^2 (going to be too much)

225 + 2025 = 2250

2250 =/= 1521

Answer:

Part I

p(x=1)=0.0000

p(x=2)=0.0000

Part II

p(x)=0.11

Step-by-step explanation:

For Poisson distribution:

$p(X=x)=e^-m\frac{m^x}{x!}$

Where m=mean, x=number of events

Given x=1, and mean,m=28

$p(X=1)=\frac{e^{-28} *28^1}{1!}\\p(X=1)=0.0000$

For x=2 and mean,m=28

$p(X=2)=\frac{e^{-28} *28^2}{2!}\\p(X=2)=0.0000$

For Uniform Distribution

Time interval 10 and 19 minutes is 9

Time interval between 15 and 16 minutes is 1

Therefore:-

$p(x)=\frac{1}{9}\\p(x)=0.1111\\p(x)=0.11 \ (2d.p)$

Asap! find the length of the arc

Fantom [35]

Answer:

A. $\frac{21}{4} \pi\ \space\ in$

Step-by-step explanation:

The formula for arc length is:

arc length = rθ

where:

r is the radius = 7 in

θ is the central angle in radians = 135 × $\frac{ \space\ \pi\ }{180}$ = 3/4 π

Substituting these values into the formula:
arc length = 7 in × 3/4 π

= $\frac{21}{4} \pi\ \space\ in$
