hoa [83]3 years ago
4 0

Answer:

looking at the image it forms

the equation it'll make B: y= -2x -4

each dot will equal -2 and the dot is maybe one 2 but thats due to the problem of 4-2x1 so it's marked on 2 instead of four incase it throw you off of thy answer of B

A banks loan officer rates applicants for credit. The ratings are normally distributed with a mean of 200 and a standard deviati
Alona [7]

Answer:

2.87%

Step-by-step explanation:

We have the following information:

mean (m) = 200

standard deviation (sd) = 50

sample size = n = 40

the probability that their mean is above 21.5 is determined as follows:

P (x> 21.5) = P [(x - m) / (sd / n ^ (1/2))> (21.5 - 200) / (50/40 ^ (1/2))]

P (x> 21.5) = P (z> -22.57)

this value is very strange, therefore I suggest that it is not 21.5 but 215, therefore it would be:

P (x> 215) = P [(x - m) / (sd / n ^ (1/2))> (215 - 200) / (50/40 ^ (1/2))]

P (x> 215) = P (z> 1.897)

P (x> 215) = 1 - P (z <1.897)

We look for this value in the attached table of z and we have to:

P (x> 215) = 1 - 0.9713 (attached table)

P (x> 215) =.0287

Therefore the probability is approximately 2.87%

I need help I<br> don’t understand what the answer is!
SVETLANKA909090 [29]

Answer:

x = -4

Step-by-step explanation:

You kind of didn't capture the directions in your image, but it looks like maybe they want you to write the equation of the line.

So this is what you need to know: the equation of a vertical (up and down) line is

x = anumber

For future reference on the next question, the equation of a horizontal (flat, left and right) line is

y = anumber

For this question, though, it's vertical.

so x = -4

You can check by picking as many points as you like and find that they ALL have -4 as the x value. Also, you will find the slope formula gives you an answer that is undefined. That's why you can't write an equation using y=mx+b. Hope this helps! I can edit if the question is something wildly different for real.

Please help with steps:<br><br> 18 - 24 (divide) (-6)
bekas [8.4K]

Answer:

Solution is 1 (one).

Step-by-step explanation:

  • The equation \frac{18-24}{-6} can be solved by solving first the expression in the numerator. This is done by solving 18-24=-6.
  • Then, you just have \frac{-6}{-6}. The negative is canceled when it appears twice, so we just have to solve \frac{6}{6}=1 (any number divided by itself equals to one).

Exxon manufacturing produces chips for computers the cost of producing X chips is given by c(x)=15x + 12000. the company sells e
valkas [14]
<span> For this case we have the following equation:
</span> c (x) = 15x + 12000&#10;
<span> Where,
 x: number of chips
 c (x): total cost
 To find the fixed cost, we must find the intersection with the y axis of the given equation.
 So we have that for x = 0:
</span> c (0) = 15 (0) + 12000&#10;&#10;c (0) = 12000<span>
 Therefore, the fixed production cost is given by:
</span> c (0) = 12000&#10;
<span> Answer:
 The fixed cost of producing the chips is:
 c (0) = 12000</span>
