Wewaii [24]3 years ago

5 0

Answer:

The correct answer is €10.00

Step-by-step explanation:

50% of 40 is 20. 50% of 50 is 25, so what you do is just take 20 and multiply that by 0.5 or you can just take 40 and multiply that by 0.25.

I really hope this helps you out!

What is the value of p? (p+2)−4=14 Drag and drop the correct answer in the box. p =

kari74 [83]

Answer:

p = 16

Step-by-step explanation:

(p + 2) - 4 = 14

We can just drop the parentheses:_

p + 2 - 4 = 14

p - 2 = 14

Add 2 to both sides:-

p - 2 + 2 = 14 + 2

p = 16

Andre is in charge of cooking brócoli and zucchini for a large group he had to spend all 17$ he has and Cary 10 pounds of veggie

nataly862011 [7]

Answer:

This is an example of equation with two unknowns. Andre bought x pounds of zucchini and y pounds of broccoli and we also know that there was 10 pounds of veggies in total. So, we can write:

$1.5 • x + $2 • y = $17

x + y = 10

From the second equation we can say that:

y = 10 - x

We can now enter this value of y into the first equation:

1.5 • x + 2 • (10-x) = 17

1.5 • x + 20 - 2 • x = 17

1.5x - 2x = 17 - 20

-0.5x = -3

0.5x = 3

x = 6

If x=6, then y=10-6, which is 4.

That means that Andre bought 6 pounds of zucchini and 4 pounds of broccoli.

Suppose that a process is currently operating at a 3.5-sigma quality level, and it is planned to use improvement projects to mov

jenyasd209 [6]

Answer:

$11,373 PPM$

Step-by-step explanation:

The following formula is used to compute the Proportion of error-free units given the sigma level in Excel.

The proportion of error-free units = NORMSDIST(Sigma Level - 1.5)

Suppose that a process is currently operating at a 3.5-sigma quality level.

The proportion of error-free units for this process is

NORMSDIST(3.5 - 1.5) = 0.977250

Therefore, the rejection rate is equal to

$1 - 0.977250 = 0.022750$

or 22750 PPM.

Now, consider a 6-sigma level process.

The proportion of error-free units equals

NORMSDIST(6.0 - 1.5) = 0.9999966

and the rejection rate is

$1 - 0.9999966 = 3.4 PPM$

Hence, reduction is PPM required per year , that is

$\dfrac{22750 - 3.4}{2} = 11,373 PPM$

reduction per year

A manufacturer determines that the number of drills it can sell is given by the formula D=-4p^2+160p-270, where p is the price o

grigory [225]

D'(p) = -8p + 160

-8p + 160 = 0 

-8p = -160 

p = 20 

~~~ 
B) Number of drills sold when p = 20 is 

D(20) = [ -4(20)^2 + 160(20) - 270 ] = 1,130 drills 

I think this is right, i tried.
