HELPPP ASAPP Bernie's Bars has determined that a granola bar measuring 3 inches long has a z-score of +1 and a granola bar measu

Len [333]

Answer:

Standard deviation of the length of granola bars produced at Bernie's Bars is 0.50

Step-by-step explanation:

We are given the following information in the question:

Formula:

$z_{score} = \displaystyle\frac{x - \mu}{\sigma}$

where,

μ is the mean and σ is the standard deviation.

Putting the values we get:

$\displaystyle\frac{ 3- \mu}{\sigma} = 1\\\\3 = \sigma + \mu\\\\\displaystyle\frac{ 3.5- \mu}{\sigma} = 2\\\\3.5 = 2\sigma + \mu$

Solving the two obtained equations:

Subtracting the two obtained equation, we have:

$3.5-3 = \mu + 2\sigma - \mu -\sigma\\\sigma = 0.5$

Hence, standard deviation of the length of granola bars produced at Bernie's Bars is 0.50

If f(x)=4x3+3x2−5x+20 and g(x)=9x3−4x2+10x−55, what is (g−f)(x)?

Montano1993 [528]

Answer:

Step-by-step explanation:

(g-f)(x) = 9x³ - 4x² + 10x - 55 - [ 4x³ +3x² - 5x + 20]

To remove the parenthesis, take - inside, multiply f(x) by -1

= 9x³ - 4x² + 10x - 55 - 4x³ - 3x² + 5x - 20

Now, bring like terms together,

= 9x³ - 4x³ - 4x² - 3x² + 10x + 5x - 55 - 20

= 5x³ - 7x² + 15x - 75
