What is √80k3 expressed in simplest radical form?
Answer:
The answer is A.
Step-by-step explanation:
Simplify the radical by breaking the radicand up into a product of known factors, assuming positive real numbers.
√[tex]80k^3[/tex] expressed in simplest radical form is 4√[tex](5k^2)[/tex].
To simplify the expression √[tex]80k^3[/tex] (square root of [tex]80k^3[/tex]) in its simplest radical form, you can break down [tex]80k^3[/tex] into its prime factors:
[tex]80k^3 = 2^4 * 5 * k^3[/tex]
Now, take the square root of each factor:
√[tex]80k^3[/tex] = √[tex](2^4 * 5 * k^3)[/tex]
Since square roots of perfect squares simplify to whole numbers, and the square root of [tex]k^3[/tex] is [tex]k^{3/2}[/tex], the simplified radical form is:
√[tex]80k^3[/tex] = [tex]2^2[/tex] * √[tex](5k^2)[/tex] = 4√[tex](5k^2)[/tex]
Therefore, √[tex]80k^3[/tex] expressed in its simplest radical form is 4√[tex](5k^2)[/tex].

An employee is asked to calculate the chi-square value, for company data set for which observed frequency is 9.5 and expected frequency is 19. What will be the Chi-Square value
Answer:
X² =4.75
Step-by-step explanation:
The formula for calculating the chi square value is expressed as
X² = [ (O - E)²/ E ].
O is the observed frequency
E is the expected frequency
Given
O = 9.5
E = 19
Substitute into the formula:
X² = (9.5-19)²/19
X² = 9.5²/19
X² = 90.25/19
X² = 4.75
Hence the chi square value will be 4.75

A.-2
B. 0
C. 2
D. Undefined
Answer:
Undefined
Step-by-step explanation:
If the slope was a horizontal line, then we could say y=2, however, it is only going through the x-axis so it would be x=2, but in terms of y it is undefined.

If a square has the sides of 6 cm then how far will it be from one corner of the square to the opposite corner?
Answer:
8.5 cm
Step-by-step explanation:
We know that the square has side lengths of 6cm. To calculate the distance from one corner of the square to the opposite corner, we are calculating the diagonal of the square.
Along the diagonal is where the square gets split in half into two right triangles. The Pythagorean theorem states that [tex]a^2+b^2=c^2[/tex] where c is the longest side of a right triangle and a and b are the other two sides.
To find the length of the square's diagonal, we essentially need to calculate c, the longest side of the triangles. We can do this by plugging 6 into the equation as a and b.
[tex]a^2+b^2=c^2\\6^2+6^2=c^2\\36+36=c^2\\72=c^2\\\sqrt{72} =c[/tex]
[tex]8.5[/tex] ≈ [tex]c[/tex]
Therefore, it will be approximately 8.5cm from one corner of the square to the opposite corner.

The pitcher from the home team had 12 strikeouts for 32 batters, While the pitchers for the visiting team had 15 strikeouts for 35 battters. which pitching team had a greater fraction of strikeouts?
really think about this one to help me!
Answer:
The visiting team had a greater fraction of strikeouts
Step-by-step explanation:
Ratios
The ratios are useful to compare rates of change or average values. In our case, we need to compare the average of strikeouts from two teams.
The home team had 12 strikeouts for 32 batters. This gives an average of:
[tex]\frac{12}{32}=0.38[/tex]
The visiting team had 15 strikeouts for 35 batters for an average of:
[tex]\frac{15}{35}=0.43[/tex]
The visiting team had a greater fraction of strikeouts

Tyler ate x fruit snacks, and Han ate 3/4 less than that. Write an equation to represent the relationship between the number Tyler ate (x) and the number Han ate (y).
Answer:
0.75x = y
Step-by-step explanation:
The required expression represents the relationship between the number Tyler ate (x) and the number Han ate (y) is y = x/4.
What is the equation?The equation is the relationship between variables and represented as y = ax + b is an example of a polynomial equation.
Here,
Tyler ate x fruit snacks, and Han ate 3/4 less than that
Let the snacks eaten by Han be y,
According to the question,
y = x - 3/4x
y = x/4
Thus, the required expression represents the relationship between the number Tyler ate (x) and the number Han ate (y) is y = x/4.

Please help ❤️
Answer:
y = -2, 1, 4, 7 (in order)
Step-by-step explanation:
Plug in the value of x into the equation to find y.
For example for -1, plug in x as -1 into the equation.
y = 3(x) +1
y = 3(-1) + 1
y = -2
Similarly plug in the x to find the rest of the values for y.

help ! need an explanation and answer!
Answer:
as below
Step-by-step explanation:
because the interior angles add up to 180 degrees.. you can solve this
180= 32 + 64 + x hmm
84 = x
so the last angle is 84° :)
as we know that the sum of three interiors angle = 180
Two angles are given 32 and 64
let the angles be a , b and c
A + B + C = 180
32 + 64 + C = 180
C = 180-96
C = 84
Hence the 3rd angle is 84
