Product factor is an expression in where you multiply the same value digit many times.
Exponent is the expression in where you convert product factor expression into a shorter expression
For example of product factor:
=> 9 x 9 x 9 x 9 x 9 x 9 x 9 x 9 x 9
As you can see, 9 is multiplied many times, that makes it longer.
Now, let’s make this product factor shorter using exponent.
=> since 9 is multiplied 9 times the exponent expression is:
=> 9 9 in where 9 is the base and the other 9 is called exponent.

let x be the money she invested

lets assume this was for 1 year

0.09(x/2) + 0.07(x/2) = 160

multiply each side by 2 to cancel the denominators:

0.09x + 0.07x = 320

statuscvo [17]

Answer:

1) The probability that the mean mpg for a random sample of 25 light vehicles is 0.042341.

2) between 20 and 25 --> 21-25/2.9 = -1.38

Step-by-step explanation:

Problem #1:

  • Using the z-score formula, z = (x-μ)/σ/n, where x is the raw score = 20 mpg,μ is the population mean = 21 mpg , σ is the population standard deviation = 2.9, n = random number of samples.
<h3><u>X < 20</u></h3>
  • = z = 20 - 21/2.9/√25
  • = z = -1/2.9/5
  • = z = -1.72414
<h2><u><em>Now</em></u></h2>

<em>P-value from Z-Table:</em>

<h3><u>P(x<20) = 0.042341</u></h3>

Problem #2:

<h3>21-25/2.9 = -1.38</h3>
