The area (A) of a circle with radius r is given by

... A = π·r²

For a radius of 7 ft, the area is

... A = π·(7 ft)² = 49π ft² ≈ 154 ft²

The area of the bottom of a circular tent with radius 7 ft is about 154 ft².

Galina-37 [17]

Answer:

The probability of randomly selecting a rod that is shorter than 22 cm

P(X<22) = 0.1251

Step-by-step explanation:

Step(i):-

Given mean of the Population = 25cm

Given standard deviation of the Population = 2.60

Let 'x' be the random variable in normal distribution

Given x=22

$Z = \frac{x-mean }{S.D} = \frac{22-25}{2.60} = -1.15$

Step(ii):-

The probability of randomly selecting a rod that is shorter than 22 cm

P(X<22) = P( Z<-1.15)

= 1-P(Z>1.15)

= 1-( 0.5+A(1.15)

= 0.5 - A(1.15)

= 0.5 - 0.3749

= 0.1251

The probability of randomly selecting a rod that is shorter than 22 cm

P(X<22) = 0.1251

Keep in mind that, when the logarithm base is not explicitly written, base 10 is assumed, therefore,

$\bf \textit{Logarithm Cancellation Rules}\\\\
log_a a^x\implies x\qquad \qquad a^{log_ax}=x\\\\
-------------------------------\\\\
10^{log(3)}+log(100)\implies 10^{log_{10}(3)}+log_{10}(100)\implies 3+log_{10}(10^2)
\\\\\\
3+2\implies 5$

X+(x+2)+(x+4)+(x+6)=4x+12=212

Mrac [35]

(x+(x+2)+(x+4)+(x+6))=4x+12=212

x+x+x+x(2+4+6)=4x+12=212

4x (2+4+6)=4x+12=212

4x(6+6)=4x+12=212

12+4x=4x+12=212

-12 -12 -12

4x=4x=200
