Step-by-step explanation:

25C=4 mins

10C*10 mins =1$

$1.25

2.10-1.25=.85

10C*8=80C

user100 [1]

<u>Answer:</u>

x < 21.01 or x > 21.49 because |x - 21.25| > 0.24

<u>Step-by-step explanation:</u>

We know that each pack of almonds is targeted to weigh 21.25 oz.and a pack must weigh within 0.24 oz of the target weight to be accepted.

Assuming x to be the weight of a given pack of almonds, we can write it as:

$|x-21.25| > 0.24$

Now finding the range of rejected masses (x) of the almonds.

$|x-a| >b$

$-b$

$|x-21.25| >0.24$

$-0.24>(x-21.25)>0.24$

$-0.24>x-21.25$ or $x-21.25>0.24$

$x$ or $x>21.49$

Therefore, the correct answer option is x < 21.01 or x > 21.49 because |x - 21.25| > 0.24.

I know it has to be a negative...........

sleet_krkn [62]

Answer:

$m=-3$

Step-by-step explanation:

Choose 2 points on the graph. (-2,8) (3,-7)
Apply slope formula.

$m=\frac{rise}{run} =\frac{y2-y1}{x2-x1} \\\\\frac{-7-(8)}{3-(-2)} = \frac{-15}{3} =-3\\\\m=-3$

I hope I choose the right cordinates...

Answer: 3.6 cups or 3 3/5 cups

Step-by-step explanation: what i would do here is set up a proportion. Change 3/4c to .75 cups as it’s easier to place in a proportion (and less confusing).. cross multiply .... (.75 x 48= 36) then divide 36 by 10 and that will give you x

A roll of steel is manufactured on a processing line. The anticipated number of defects in a 10-foot segment of this roll is two

Vikentia [17]

Answer:

the probability of no defects in 10 feet of steel = 0.1353

Step-by-step explanation:

GIven that:

A roll of steel is manufactured on a processing line. The anticipated number of defects in a 10-foot segment of this roll is two.

Let consider β to be the average value for defecting

So;

β = 2

Assuming Y to be the random variable which signifies the anticipated number of defects in a 10-foot segment of this roll.

Thus, y follows a poisson distribution as number of defect is infinite with the average value of β = 2

i.e

$Y \sim P( \beta = 2)$

the probability mass function can be represented as follows:

$\mathtt{P(y) = \dfrac{e^{- \beta} \ \beta^ \ y}{y!}}$

where;

y = 0,1,2,3 ...

Hence, the probability of no defects in 10 feet of steel

y = 0

$\mathtt{P(y =0) = \dfrac{e^{- 2} \ 2^ \ 0}{0!}}$

$\mathtt{P(y =0) = \dfrac{0.1353 \times 1}{1}}$

P(y =0) = 0.1353
