If 12x=12−−√11, what value of x makes this equation true?
Solnce55 [7]

Answer:

\dfrac{1}{11}

Step-by-step explanation:

Apply exponent rule:  

\sqrt[n]{a} =a^{\frac{1}{n}}

\implies \sqrt[11]{12}=12^{\frac{1}{11}}

\implies 12^x=12^{\frac{1}{11}}

\implies x = \dfrac{1}{11}

Sound City sells the ClearTone-400 satellite car radio. For this radio, historical sales records over the last 100 weeks show 4
Ksivusya [100]

Answer:

See below

Step-by-step explanation:

\bf \mu(x) is the average

\bf \mu(x)=\frac{4*0+33*1+39*2+12*3+8*4+4*5}{100}=\frac{199}{100}=1.99\;radios/week

\bf \sigma^2(x) is the variance

\bf \sigma^2(x)=\frac{4*(0-1.99)^2+33*(1-1.99)^2+39*(2-1.99)^2+12*(3-1.99)^2+8*(4-1.99)^2+4*(5-1.99)^2}{100}=\frac{128.99}{100}=1.2899

\bf \sigma(x) is the standard deviation

\bf \sigma(x)=\sqrt{variance}  

\bf \sigma(x)=\sqrt{1.2899}=1.1357\;radios/week

A rectangle has an area of 105 square feet. If the sum of the length and the width is 26 feet, find the dimensions. Include unit
Andrei [34K]

L x W = 105

L + W = 26 so L = 26 - W

substitute L = 26 - W into L x W = 105


(26 - W) x W = 105

26W - W^2 = 105

W^2 - 26W + 105 = 0

(W - 21)(W - 5) = 0

W - 21 = 0; W = 21

W - 5 = 0; W = 5


The the dimensions of the rectangle are 5 ft and 21 ft.


Double check:

The sum of the length and the width is 26 feet: 21 + 5 = 26 feet

A rectangle has an area of 105 square feet: 21 x 5 = 105 square feet
