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.

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

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.

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.

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

Answer:

a = 3

Step-by-step explanation:

The vertex form of a quadratic is

y = a(x-h) ^2 +k  where ( h,k) is the vertex

the vertex is (-2,2)

y = a(x- -2) ^2 +2

y = a(x+2) ^2 +2

Pick another point on the graph to determine a

(-1,5) and substitute into the equation

5 = a( -1+2) ^2 +2

5 = a(1)^2 +2

5 = a(1) +2

Subtract 2 from each side

5-2 = a+2-2

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

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.

Answer:

the lowest common multiple is 60

Step-by-step explanation:

The multiples of 12 are : 12, 24, 36, 48, 60, 72, 84,

The multiples of 15 are : 15, 30, 45, 60, 75, 90, ....

60 is a common multiple (a multiple of both 12 and 15), and there are no lower common multiples.

Therefore, the lowest common multiple of 12 and 15 is 60.

Answer:

[tex]60[/tex]

Step-by-step explanation:

Least Common Multiplier (LCM)

The LCM of [tex]a,b[/tex] is the smallest positive number that is divisible by both [tex]a[/tex] and [tex]b[/tex]

Prime factorization of [tex]12[/tex]

[tex]12[/tex]

[tex]12[/tex] divides by [tex]2[/tex]     [tex]12=6*2[/tex]

[tex]=2*6[/tex]

[tex]6[/tex] divides by [tex]2[/tex]     [tex]6=3*2[/tex]

[tex]2,3[/tex] are both prime numbers, therefore no further factorization is possible

[tex]=2*2*3[/tex]

Prime factorization of [tex]15[/tex]

[tex]15[/tex]

[tex]15[/tex] divides by [tex]3[/tex]    [tex]15=5*3[/tex]

[tex]3,5[/tex] are both prime numbers, therefore no further factorization is possible

Multiply each factor the greatest number of times it occurred in either [tex]12[/tex] or [tex]15[/tex]

[tex]=2*2*3*5[/tex]

Multiply the numbers: [tex]2*2*3*5=60[/tex]

[tex]=60[/tex]

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].

Answer:

m=0

Step-by-step explanation:

We simplify the equation to the form, which is simple to understand  

93+12m=3(4m-1)+96

Reorder the terms in parentheses

93+12m=+(+12m-3)+96

Remove unnecessary parentheses

+93+12m=+12m-3+96

We move all terms containing m to the left and all other terms to the right.  

+12m-12m=-3+96-93

We simplify left and right side of the equation.  

m=0
