Answer:

\boxed{z = -7}

Step-by-step explanation:

=  >  - 9 + 8(14z  + 2) = 7(17z + 8) \\  \\  =  >  - 9 + (8 \times 14z + 8 \times 2) = (7 \times 17z) + (7 \times 8) \\  \\  =  >  - 9 + 112z + 16 = 119z + 56 \\  \\  =  >  7 + 112z = 119z + 56\\  \\  =  >  7 + 112z - 119z = 56 \\  \\  =  >   7 - 7z = 56 \\  \\  =  >  - 7z = 56 - 7 \\  \\  =  >  - 7z = 49 \\  \\  =  > 7z =  - 49 \\  \\  =  > z =  -  \frac{49}{7}  \\  \\  =  > z =  - 7

Answer:

z=-7

Step-by-step explanation:

-9+8*14z+8*2=7*17z+7*8

-9+112z+16=119z+56

112z+7=119z+56

-112z       -112z

7=7z+56

-56    -56

-49=7z

:7     :7

z=-7

Periodically, Merrill Lynch customers are asked to evaluate Merrill Lynch financial consultants and services. Higher ratings on
Vlada [557]

Answer:

See the explanation

Step-by-step explanation:

(a)  

H0: Consultant with more experience has the higher population mean service rating.

H1: Consultant with more experience doesn't have the higher population mean service rating.

(b)  

t = 1.9923 (see the attached image)

(c)

The degrees of freedom for the test statistic,

df = 16

The P-value of the one tailed t- test with 16 degrees of freedom is,

P−value = tdist(X,df,tails)

P-value = tdist(1.9923,16,1)

P-value = 0.032

(d)​

Since, P-value 0.032 is less than the significance level 0.05, there is an enough evidence to reject the null hypothesis.

Hence, there is a sufficient evidence to conclude that Consultant with more experience doesn't have the higher population mean service rating.

Hope this helps!

There is a rectangular terrain with dimensions "x" and "y". If it is known that its area of ​​is 22m ^ 2 and that x ^ 2 + y ^ 2
Margaret [11]

9514 1404 393

Answer:

  24 m

Step-by-step explanation:

The area formula tells us ...

  22 = xy . . . . . square meters

Adding twice this to the quadratic constraint gives ...

  (x^2 +y^2) +2(xy) = (100) +2(22)

  (x +y)^2 = 144

  x +y = √144 = 12

The perimeter is double this amount, so is ...

  P = 2(x +y) = 2(12) = 24 . . . . meters
