A cake has circumference of 25 1/7 inches. What is the area of the cake? Use 22/7 to approximate π. Round to the nearest hundred

choli [55]

Answer:

50.29 in^2

Step-by-step explanation:

From the circumference we need to find the radius.

Since C = 2*pi*r, r = C / (2*pi).

Here, with C = 25 1/7 in, r = (25 1/7 in) / [ 2(22/7) ], or r = 4 in

The area of the cake is A = pi*r^2, or (here) A = (22/7)(4 in)^2 = 50.29 in^2

You have two exponential functions. One function has the formula g(x) = 5 x . The other function has the formula h(x) = 5-x . Wh

AVprozaik [17]

Given the exponential functions $g(x)= 5^{x}$ and $h(x)= 5^{-x}$

$k(x)=(g-h)(x)$
$k(x)=g(x)-h(x)
$
$k(x)= 5^{x} - 5^{-x}$
$k(x)= 5^{x} - \frac{1}{ 5^{x} }$
$k(x)= \frac{ 5^{x} 5^{x} }{ 5^{x} } - \frac{1}{ 5^{x} }$
$k(x)= \frac{ 5^{2x} }{ 5^{x} } - \frac{1}{ 5^{x} }$
$k(x)= \frac{ 5^{2x}-1 }{ 5^{x} }$

A manufacturing firm tests job applicants. Test scores are normally distributed with a mean of 500 and a standard deviation of 5

Blababa [14]

Answer:

The probability that the candidate score is 600 or greater

P(X≥ 600 ) = 0.0228

Step-by-step explanation:

<u><em>Step(i)</em></u>:-

Given mean of the Population = 500

Given standard deviation of the Population = 50

Let 'X' be the random variable in normal distribution

Given X = 600

$Z = \frac{x-mean}{S.D} = \frac{600-500}{50} = \frac{100}{50} =2$

<u><em>Step(ii)</em></u>:-

The probability that the candidate score is 600 or greater

P(X≥ 600 ) = P(z≥2)

= 0.5 - A(2)

= 0.5 -0.4772

= 0.0228

<u><em>Final answer</em></u>:-

The probability that the candidate score is 600 or greater

P(X≥ 600 ) = 0.0228
