The radical form of 194 = √2 x √97
To find the radical form of 194,
we need to factorize it into its prime factors.
So, let's start by dividing 194 by the smallest prime factor, which is 2,
⇒ 194 ÷ 2 = 97
We can see that 97 is a prime number,
so we can't divide it any further.
Therefore, the prime factorization of 194 is,
⇒ 194 = 2 x 97
Now, we can write the radical form of 194,
⇒√194 = √(2 x 97)
We can simplify this expression by breaking it down into the product of two separate square roots:
⇒ √(2 x 97) = √2 x √97
⇒The radical form of 194 is √2 x √97.

Answer:
0.9533
Step-by-step explanation:
(a) Probability that a randomly selected woman's height is less than 65 inches:
Using the z-score formula:
�
=
�
−
�
�
Z=
σ
X−μ
Where:
�
X = 65 inches
�
μ = 64.3 inches
�
σ = 2.7 inches
�
=
65
−
64.3
2.7
≈
0.2593
Z=
2.7
65−64.3
≈0.2593
Now, find the probability associated with this z-score, which is approximately 0.6010 (rounded to four decimal places).
(b) Probability that the mean height of 43 randomly selected women is less than 65 inches:
Using the Central Limit Theorem:
�
μ (mean of the sample means) remains 64.3 inches.
�
sample mean
σ
sample mean
(standard deviation of the sample means) is calculated as
2.7
43
≈
0.4115
43
2.7
≈0.4115.
Now, find the z-score for a sample mean of 65 inches:
�
=
65
−
64.3
0.4115
≈
1.6924
Z=
0.4115
65−64.3
≈1.6924
The probability associated with this z-score is approximately 0.9533 (rounded to four decimal places).
It can be reflected onto itself across four different lines of reflection.
Which kind of polygon must it be?
The number is 8.
To solve this equation, we can set it up as follows:
Let x be the unknown number.
x + 7 = 15
x + 7 - 7 = 15 - 7
x = 15 - 7
x = 8
So, the unknown number is 8.
To write the expression, I'll follow these steps :
↠ First, I am going to choose a letter that will represent my number.
↠ Then I'll plug it into the expression, and write the rest.
STEP ONE
I'll choose d for my number.
STEP TWO
We now have : d increased by 7 is 15, which is the same thing as d + 7 = 15.
To find d, subtract 7 from both sides :
d = 15 - 7 = 8
Therefore, d = 8.
Answer: The required product is
Step-by-step explanation: We are to find the product f the following two algebraic expressions:
To find the product of the above two expressions, we must multiply each term of the first expression with each term of the second expression.
The multiplication is as follows:
Thus, the required product is
Answer:
Step-by-step explanation:
Given expressions are 2x+ y and 5x -y +3
Product of 2x+y and 5x-y+3 is
( by applying distributive property under multiplication over addition)
⇒ (again by distributive property)
⇒ ( by operating the like terms.)
Answer:
The additive inverse of given expression is .
Step-by-step explanation:
The given polynomial is
Let a be any number and b is its additive inverse, then
The value of b is equal to -a. It means the additive inverse of a is -a.
The additive inverse of given expression is
Therefore the additive inverse of given expression is .
