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

Please help- I don't know math very well :(

Vanyuwa [196]

$\\ \sf\longmapsto f(x)=4(x-3)$

$\\ \sf\longmapsto f(3)$

$\\ \sf\longmapsto 4(3-3)$

$\\ \sf\longmapsto 4(0)$

$\\ \sf\longmapsto 0$

Here

a_n=7n

$\\ \sf\longmapsto a_{10}=7(10)=70$

d=1/4

a=1/4

$\\ \sf\longmapsto a_4=a+(n-1)d$

$\\ \sf\longmapsto a_4=\dfrac{1}{4}+(3)(\dfrac{1}{4})$

$\\ \sf\longmapsto a_4=1$

$\\ \sf\longmapsto y=2x-8$

$\\ \sf\longmapsto 2x=y+8$

$\\ \sf\longmapsto f(x)=\dfrac{8+y}{2}$

$\\ \sf\longmapsto a_n=n-1$

$\\ \sf\longmapsto 4.5- 4(0.5)$

$\\ \sf\longmapsto 4.5-2$

$\\ \sf\longmapsto 2.5$

A dartboard has a diameter of 18 inches.what are its radius and circumference?

sineoko [7]

We know, radius = diameter / 2 = 18 / 2 = 9 in.
Circumference = 2πr = 2π(9) = 18π = 18 * 3.14 = 56.52 in.

Hope this helps!
