Step-by-step explanation:

-An experimental unit is any physical entity or person or animal that can be randomly assgned to a treatment.

-Such a unit is usually referred to as a unit of statistical analysis.

-Both control and actual experimental units are units of statistical analysis despite receiving different treatments.

-Hence, the experimental units of the study is 50 people.

What is the solution of √-4x=100? A) x = –2500 B) x = –50 C) x = –2.5 D) no solution

yawa3891 [41]

First we raise both members of the equality to the square:
(√-4x) ^ 2 = (100) ^ 2
Then, we solve:
-4x = 10000
We cleared x in the last instance
x = 10000 / (- 4)
x = -2500
answer:
the solution of √-4x=100 is
A) x = –2500

Find the first four iterates of the function f(x) = x2 with an initial value of x0 = -1.

jasenka [17]

Option A: 1,1,1,1 is the right answer

Step-by-step explanation:

In finding the function iterates we start with the initial value and put the initial value into the function and then the output of previous iterate is used as input for next iterate

Given

$f(x) = x^2\\and\\x_0 = -1$

First iterate:

Putting x=-1 in the function

$f(-1) = (-1)^2\\=1$

Second iterate:

Putting x=1

$f(1) = (1)^2\\=1$

Third iterate:

Putting x=1

$f(1) = (1)^2\\=1$

Fourth iterate:

Putting x=1

$f(1) = (1)^2\\=1$

First four iterates of given function with initial value -1 are: 1,1,1,1

Hence,

Option A: 1,1,1,1 is the right answer

Substituting x= -3 in x2 + 5x +4 gives?

KATRIN_1 [288]

Answer:

-2

Step-by-step explanation:

If we replace all the spots where x is with -3, we get this: (-3)^2 + 5(-3) + 4. Then we get... 9 + -15 + 4 which equals -2
