Answer:
17400
Step-by-step explanation: i might get this wrong but just do 1.74*10^4 and it should equal 17400
Answer:
The 12 children selected in Mrs. Smith's kindergarten class.
Step-by-step explanation:
A sample is a representative part of a population on which a research is carried out.
The study In Mrs Smith's class was to find out the number of hours the children in Kindergarten Sleep in a day. Out of the total number of students, 12 were selected for observation. The 12 childen selected is therefore a sample of the class.
The sample in the study refers to the 12 children in Mrs. Smith's kindergarten class. A sample is a subset of people selected from a larger group for study purposes. In this research, the data being analyzed only pertains to these selected individuals.
In this study, the sample chosen is the group of 12 children in Mrs. Smith's kindergarten class. This is because the data being collected and scrutinized is related to these particular individuals. In this context, 'sample' refers to the subset of people chosen from a larger group (the population) for research or study purposes. It is the set of individuals on which the study or experiment is conducted. In this case, the larger population could be considered all children in kindergarten, but the sample for the study is specifically the 12 children in Mrs. Smith's class, as the study only includes their sleep patterns.

Answer:
9530 cg
Step-by-step explanation:
b) –2 – i
c) 2 + i
d) 2 – i
Answer
d) 2 – i
Explanation
f(x) = x³ – 2x²
When x = i, we proceed as follows.
Note: i =
i² =(√-1)(√-1) = -1
i³ = (√-1)(√-1)(√-1) = -1(√-1) = -1i = -i
f(x) = x³ – 2x²
f(i) = i³ – 2i²
= -i – 2(-1)
= -i + 2
= 2 – i
Answer:
f(i)=2-i
d is the correct option.
Step-by-step explanation:
The given function is
Substitute x = i, to find f(i)
We can rewrite this as
Now, we know that. Thus, we have
On simplifying, we get
d is the correct option.
There is one solution to the equation, so let's solve it :D1
Step - Divide both sides of the equation by -11
-11m/-11 = -132/-11
FINAL ANSWER --
m = 12

The value of z in the following equation 2(4z − 9 − 7) = 166 − 46 is 19. Details about solving equations can be found below.
An algebraic equation is a mathematical equation in which one or both sides is an algebraic expression, such as 2x + 7y = 3.
The following algebraic equation is given in this question; 2(4z − 9 − 7) = 166 − 46. The value of z can be calculated as follows:
8z -18 - 14 = 120
8z - 32 = 120
8z = 152
z = 152/8
z = 19
Therefore, the value of z in the following equation 2(4z − 9 − 7) = 166 − 46 is 19.
