A factory is currently running at 85% of its original capacity, and management is considering upgrading the equipment.

1 answer:

6 0

I will take the sugestion, so 85 units per month (100 is full capacity)

so while doing maintinance, the 6 months is wasted, 0 ouput, basically 85*6=510 lost

now we have to see how many months x it takes for the output to match

the output that would have been is
510+85x
the output now is 120x
so
510+85x=120x
minus 85x both sides
510=35x
divide both sides by 35
14.57=x
round up
15 months needed

The population of weights of a particular fruit is normally distributed, with a mean of 464 grams and a standard deviation of 6

igomit [66]

Answer:

If 27 fruits are picked at random, then 2% of the time, their mean weight will be greater than 466.37 grams

Step-by-step explanation:

Mean = $\mu = 464$

Standard deviation = $\sigma = 6$

We are supposed to find If 27 fruits are picked at random, then 2% of the time, their mean weight will be greater than how many grams i.e.P(X>x)=0.02

The mean weight is in the highest 2%, you want to go to a z-table and find the z-score that where the area to the left of the curve is closest to 0.98.

n = 27

Refer the z -table

P(Z>x)=2.06

$\frac{x-\mu}{\frac{\sigma}{\sqrt{n}}}=2.06\\\frac{x-464}{\frac{6}{\sqrt{27}}}=2.06\\x-464=2.06 \times \frac{6}{\sqrt{27}}\\x=(2.06 \times \frac{6}{\sqrt{27}})+464\\x=466.37$

So, If 27 fruits are picked at random, then 2% of the time, their mean weight will be greater than 466.37 grams

PLEASE HELP ASAP 50 POINTS AND BRAINLYEST

Ludmilka [50]

Answer:

Either x = 3, y = 2

(3,2) is your answer.

Step-by-step explanation:

2x +y = 8 (1)

y = - x+ 5 (2)

Put equation (2) into equation (1). Use the y value in (2) to go into the y value in (1).

2x - x+5 = 8 Combine the x values

x + 5 = 8 Subtract 5 from both sides

x + 5-5 = 8-5

x=3

Now go back to (2). Put x in for the value of -x. Watch the sign.

y = -3+ 5

y = 2

So the answer is (3,2)
