Im really sorry if im wrong
Answer:
(a) 3, 5 and 6
Step-by-step explanation:
In the experiment, 43 are to be given a gel that contains the tooth-whitening chemicals while the remaining 42 are to be given a placebo. Therefore, a placebo is used.
The 43 that will receive the gel are to be selected randomly.
After the experiment, the whiteness of the two groups will be compared to see the effect of the gel.
Therefore for the experiment to be completely random, 3, 5, and 6 apply.
(b)
For the experiment to be double-blind, the researchers who will evaluate the whiteness and interact with the subjects, and the subjects would not know which subjects received either the whitening gel or the placebo.
Answer:
squareroot of 7 < 14/5
Step-by-step explanation:
We are given that two real numbers
squareroot of 7 and 14/5
We have to compare the given two real numbers and fill the mathematical symbol in the blank
In order to compare the given real number we will find the value of given real numbers .
Value of squareroot of 7 = 2.646
Value of 14/5 = 2.8
Value of 2.645 is less than 2.8.
Hence, squareroot of 7 is less than 14/5
hope i helped! :D

Answer:
x ≈ 6
Step-by-step explanation:
The legs of an isosceles triangle are congruent , both 2x - 4 , then
x + 2x - 4 + 2x - 4 = 24 , that is
5x - 8 = 24 ( add 8 to both sides )
5x = 32 ( divide both sides by 5 )
x = 6.4 ≈ 6 ( to the nearest whole number )
Answer:
10
-------------
3x^2
Step-by-step explanation:
First lets simplify what is inside the square root
300x8
---------------
27x12
3 * 100 x^8
------------------
3 *9 x^12
The 3's cancel and we know a^b/ a^c = a^(b-c)
100/9 x^ (8-12)
100/9 x^-4
sqrt( 100/9 x^-4)
Put the negative exponent in the denominator and make it positive
sqrt( 100 / (9x^4) )
We know that sqrt( a / b) = sqrt(a) / sqrt( b)
sqrt(100)
----------------
sqrt( 9x^4)
10
-------------
3x^2
