EastWind [94]3 years ago
6 0

Answer:

The correct option is the second option

Step-by-step explanation:

From the question we are told that

   The average cost is  \mu =  \$ 200 000.00

   The sample size is  n =  65  

    The upper limit of the 95% confidence interval is  $1050.00

     The lower limit of the 95% confidence interval is $850.00

From the question we are told the confidence level is  95% , hence the level of significance is    

      \alpha = (100 - 95 ) \%

=>   \alpha = 0.05

1. A function has a second rate of change of -4. Does the function have a maximum or a minimum?
Aloiza [94]

This function would have a maximum.

Since we are subtracting by a -4 for each increase in x, we know that the numbers will continue to go down. Given this fact, we know the number will never be higher than when we started, but the number could go infinitely low. As a result we have a maximum and no minimum.

There is a number such that four times the number plus 3 is equal to 19. Find the number
frosja888 [35]

Answer:

4

Step-by-step explanation:

We have been given that it equals 19 when added to 3 and multiplied by 4 so follow these steps:

1. set the equation 4x+3=19

2. solve for x

4x+3-3=19-3

This is used to solve for x

3. 4x=16 is found

4. if 4x=16, we divide 16/4 and get 4!

That's your answer hope it helped!

Find the length of BC. <br> A.) 14<br> B.) 9<br> C.) 2<br> D.) 3
Vera_Pavlovna [14]

Answer:

A) 14

Step-by-step explanation:

BC is congruent to DC in saying this you can plug the equations to each other and solve for y and then put its back into the equation for BC to get the length.

3y+5=5y-1

subtract 3y from both sides --> 5=2y-1

add 1 to both sides --> 6=2y

now get y alone, divide by 2 by both side --> y=3

plug y in back to 5y-1 --> 5x3-1

15-1

BC = 14
