Answer: y = 0
Note: of course you don't need to type in the "y=" part as its already taken care of

----------------------------------------------------------

The highest point is when y = 5
The lowest point is when y = -5
Find the midpoint of those y values. Add them up: 5 + (-5) = 0
Then divide that result by 2: 0/2 = 0

The midpoint of 5 and -5 is 0. So the midline is y = 0
This is the center horizontal line that runs through the middle of the sinusoidal curve
The vertical distance from the midline to either the peak or valley is the same (in this case, 5) which is known as the amplitude

The highest point is when y (maximum) = 5

The lowest point is when y (minimum) = -5

midline=maximum+minimum/2

5-5=0/2=0

The midline is 0

Triss [41]
Increases by 3 each time
aritmetic sequence, firsrt term is 34, 3=common differnce
an=a1+d(n-1) is da formlua
a1=first term
d=common differnce
an=34+3(n-1)
so 32n'd term is
a32=34+3(32-1)
a32=34+3(31)
a32=34+93
a32=127
the 32nd term is 127

The mean per capita income is 20,90820,908 dollars per annum with a standard deviation of 407407 dollars per annum. What is the
LiRa [457]

Answer:

z=\frac{20880-20908}{\frac{407}{\sqrt{55}}}= -0.51

z=\frac{20936-20908}{\frac{407}{\sqrt{55}}}= 0.51

Then we can find the probability of interest with this difference:

P(-0.51

And using the normal standard distribution or excel we got:

P(-0.51

So then the probability  that the sample mean would differ from the true mean by less than 28 dollars from the sample of 55 is approximately 0.390

Step-by-step explanation:

We define the variable of interest as the per capita income and we know the following properties for this variable:

\mu=20908 and \sigma=407

We want to find this probability:

P(20908-28

We select a sample size of n=55 and we define the z score formula given by:

z=\frac{x-\mu}{\frac{\sigma}{\sqrt{n}}}

We can find the z score then for 20880 and 20936 and we got:

z=\frac{20880-20908}{\frac{407}{\sqrt{55}}}= -0.51

z=\frac{20936-20908}{\frac{407}{\sqrt{55}}}= 0.51

Then we can find the probability of interest with this difference:

P(-0.51

And using the normal standard distribution or excel we got:

P(-0.51

So then the probability  that the sample mean would differ from the true mean by less than 28 dollars from the sample of 55 is approximately 0.390

Find the missing term.
Oksi-84 [34.3K]

Answer:

-2 - 24i

Step-by-step explanation:

a + bi + (7 - 3i) + (5 + 9i) + 13i = 10 - 5i

a + bi + <u>7 + 5</u>  - 3i + 9i + 13i = 10 - 5i

                a + bi  + 12  + 19i = 10 - 5i

                         a + bi          = 10 - 5i - 12 - 9i

                                 a + bi = 10 - 12 - 5i - 9i

                                 a + bi = -2 - 24i
