Explain the process of changing rational exponents to radical form

hoa [83]

The formula that describes the transformation of rational exponents to radical form is:

$a^{\frac{n}{m}} = \sqrt[m]{a^n}$

<h3>Transformation of rational exponents to radical form:</h3>

A rational exponent is represented by: $a^\frac{m}{n}$ .

That is, the exponent is a fraction, in which m is the numerator and n is the denominator.

In the conversion to radical form, the numerator will be power(also exponent), while the denominator will be the root.

Hence, the formula for the transformation is:

$a^{\frac{n}{m}} = \sqrt[m]{a^n}$

The operation manager at a tire manufacturing company believes that the mean mileage of a tire is 44,663 miles, with a standard

expeople1 [14]

Answer:

The probability is $P(| \= X- \mu| < 199 ) = 0.733$

Step-by-step explanation:

From the question we are told that

The mean mileage of a tire is $\mu = 44663$

The standard deviation is $\sigma = 2594$

The sample size is n = 209

Generally the standard error of mean is mathematically represented as

$\sigma_{x} = \frac{\sigma}{\sqrt{n} }$

=> $\sigma_{x} = \frac{2594}{\sqrt{209} }$

=> $\sigma_{x} = 179.4$

Generally the probability that the sample mean would differ from the population mean by less than 199 miles is mathematically represented as

$P(| \= X- \mu| < 199 ) = P(|\frac{\= X - \mu}{ \sigma_{x}}| < \frac{199}{ 179.4})$

$\frac{\= X -\mu}{\sigma } = Z (The \ standardized \ value\ of \ \= X )$

=> $P(| \= X- \mu| < 199 ) = P(|Z| < \frac{199}{ 179.4})$

=> $P(| \= X- \mu| < 199 ) = P(|Z|< 1.11)$

=> $P(| \= X- \mu| < 199 ) = P(-1.11 \le Z \le 1.11 )$

=> $P(| \= X- \mu| < 199 ) = P(Z \le 1.11 ) - P( Z \le -1.11 )$

From the z table the area under the normal curve to the left corresponding to 1.11 and -1.11 is

$P(Z \le 1.11 ) = 0.8665$

and

$P(Z \le - 1.11 ) = 0.1335$

So

$P(| \= X- \mu| < 199 ) = 0.8665 - 0.1335$

=> $P(| \= X- \mu| < 199 ) = 0.733$

Does anyone know the answer to this

Alex17521 [72]

Answer: y=-x-8

Step-by-step explanation:

x-int: (-8, 0)

y-int: (0, -8)

m=(y2-y1)/(x2-x1)

m=(-8-0)/(0-(-8))

m=-8/(0+8)

m=-8/8

m=-1

y=mx+b

y=-x+b

-8=-0+b

b=-8

y=-x-8

The ratio of boys to girls is 5 to 9. If there are 120 more girls than boys, how many boys are there? Can you please show work o

poizon [28]

5*30 = 150
9*30 = 270
Since the ratio is 5:9 you have to multiply both numbers in the ratio by the same constant.
I just started multiplying by 10, then 20, then 30 until I got numbers that had a difference of 120.
There are 150 boys.
Setting up an equation
5x + 120 = 9x
Solve for x and then multiply the ratio by the x to get the same result.
