Inga [223]

Find the intersection point between the 2 restraint equations:
$30 - 2x = 12 - \frac{1}{2} x \\ \frac{3}{2} x = 18 \\ x = 12$

Substitute back in to find y-value:
$y = 30 - 2(12) = 6$

P is maximized at point (12,6)
$P = 9(12)+9(6) = 162$

A pretzel company calculated that there is a mean of 75.4 broken pretzels in each production run with a standard deviation of 5.

Snowcat [4.5K]

Answer:

P [ Z < 66 ] = 35,15 %

Step-by-step explanation:

Normal Distribution

Population mean μ₀ = 75,4

Standard deviation σ = 5,2

Then:

P [ Z < 66 ] = ( 66 - 75,4 ) / 5,2

P [ Z < 66 ] = - 9,4 / 5,2

P [ Z < 66 ] = - 1,81

In z-table we look for the reciprocate area for that z score and find

P [ Z < 66 ] = 0,3515

P [ Z < 66 ] = 35,15 %

Guests at a pizza party are seated at three tables. The small table has 5 seats and 2 pizzas. The medium table has 7 seats and 3

bagirrra123 [75]

Answer:

the 5 seated table with the 2 pizzas got more each.

Step-by-step explanation:

$\frac{5}{2} = 2\frac{1}{y2}$ pieces each

$\frac{7}{3} = 2\frac{1}{3}$ pieces each

$\frac{12}{5} = 2\frac{2}{5}$ pieces each

Now change the fractions s that they all have a common denominator.

$2\frac{1}{2} = 2\frac{15}{30}$

$2\frac{1}{3} = 2\frac{10}{30}$

$2\frac{2}{5} = 2\frac{15}{30}$

Thus meaning that the 5 seated table with the 2 pizzas got more each.

4. Tests are performed to determine the Tool Life of a high speed steel single edge cutting tool. At a cutting speeds (v) of 180

podryga [215]

Answer:(a) n=0.233

Step-by-step explanation:

Given

We Know according to Taylor tool life

$VT^n=c$

V=cutting speed

T=tool life

n=tool life exponent

c=constant

$180\times \left ( 4.25\right )^n=110\times \left ( 35\right )^n$

$\frac{180}{110}=\left ( \frac{35}{4.25}\right )^n$

$1.636=\left ( 8.235\right )^n$

taking log both side

$\ln \left ( 1.636\right )=n\ln \left ( 8.235\right )$

n=0.233
