Answer:

Tyler's height in centimeters is, 144.78 centimeters.

Step-by-step explanation:

Given the statement: Tyler's height is 57 inches.

To find his height in centimeters.

Using the conversion:

[tex]1 {\tex}inch = 2.54 {\tex}centimeters[/tex]

Proportion states that the two ratios or fraction are equal.

Using proportion method:

[tex]\frac{1}{57} = \frac{2.54}{x}[/tex]

By cross multiply, we get

[tex]x = 57 \times 2.54 = 144.78[/tex] centimeters.

therefore, his height in centimeter is, 144.78 inches.

To convert Tyler's height from inches to centimeters, we multiply his height in inches (57) by the unit conversion factor (2.54 cm/inch), giving us 144.78 cm. Thus, Tyler's height in centimeters is 144.78 cm.

The question asks: Tyler's height is 57 inches. What could be his height in centimeters?

To answer this, we need to convert inches into centimeters. We do this using a unit conversion factor, which in this case is given as 1 inch = 2.54 centimeters. Therefore, Tyler's height in centimeters would be 57 inches multiplied by 2.54 (the unit conversion factor), giving us 144.78 cm.

Here's the step-by-step calculation:

So, Tyler's height in centimeters is 144.78 cm.

The correct answer option is [tex]f(x)=-\frac{1}{2} x+3[/tex].

Step-by-step explanation:

We will take easy (clear) points on the graph i.e. (0, 3) and (6, 0) and use them to find the equation of the line given on the graph.

To find the slope:

Slope = [tex]\frac{0-3}{6-0} =-\frac{1}{2}[/tex]

Putting the values of the coordinates of one of the chosen points and slope of the line in the standard form of equation of a line to find the y-intercept (c).

[tex]y=mx+c[/tex]

[tex]3=-\frac{1}{2} (0)+c\\\\c=3[/tex]

So the equation of the graphed line in terms of f(x) will be:

[tex]f(x)=-\frac{1}{2} x+3[/tex]

[tex]\text{Let}\ k:y=m_1x+b_1\ \text{and}\ l:y=m_2x+b_2.\\\\l\ \perp\ k\iff m_1m_2=-1\to m_2=-\dfrac{1}{m_1}\\\\\text{We have the line in point-slope form:}\\\\y-y_1=m(x-x_1)\\\\m-slope\\\\y-2=\dfrac{7}{3}(x+5)\to m_1=\dfrac{7}{3}\\\\\text{therefore}\ m_2=-\dfrac{1}{\frac{7}{3}}=-\dfrac{3}{7}.\\\\\text{We have the slope}\ m=-\dfrac{3}{7}\ \text{and the point}\ (-4,\ 9).\ \text{Substitute:}\\\\y-9=-\dfrac{3}{7}(x-4))\\\\\boxed{y-9=-\dfrac{3}{7}(x+4)}[/tex]

Answer:

Probability states the ratio of number of favorable outcomes to the total number of possible outcomes.

i.e,  [tex]probability = \frac{Number of favourable outcomes }{Total number of possible outcomes}[/tex]

A bag contains:

Red marbles = 2

Purple marble = 1

Total number of possible outcomes = (4+3+2+1) = 10 marbles

P(Brown marbles) = [tex]\frac{4}{10}=\frac{2}{5} = 40\% = 0.4[/tex]

P(Green marbles) = [tex]\frac{3}{10} = 30\% = 0.3[/tex]

P(Red marbles) = [tex]\frac{2}{10}=\frac{1}{5} = 20\% = 0.2[/tex]

and

P(Purple marbles) = [tex]\frac{1}{10}= 10\% = 0.1[/tex]

Answer:The possible outcome would be 10, because 4 brown marbles + 2 red marbles + 1 purple marble+3 green marbles = 10 outcomes!

Linear function ;

y =2x

Step-by-step explanation:

The formula y=f(x)=mx +c  ......[1]  is said to be a linear function. That means the graph of this function will be a straight line on the (x, y) plane, where m represents slope and b is the y-intercepts.

Consider any points from the table;

(1, 2) and (2, 4)

substitute these point in [1] we get;

for (1, 2)

⇒x = 1 and f(x) = 2 we have

2 = m + c      

or

c = 2- m                       ......[1]

for (2, 4) we have;

4 = 2m + c                       .....[2]

Now, substitute equation [1] into [2] we get;

4 = 2m + 2 -m

Combine like terms;

4 = m + 2

Subtract 2 from both sides we get;

4 -2 = m +2 -2

Simplify:

2 = m or

m = 2

Substitute the value of m = 2 in [1] to solve for c;

c = 2 -2 = 0

c =0

⇒ y = 2x +0

y = 2x

therefore, the data in the table represents the Linear function and a possible formula for the linear function is; y = 2x

Answer:

Option B. y = 2x

Step-by-step explanation:

The given table in the question is

x      0       1       2       3      4      

f(x)   0       2      4       6      8

As we know if the function is exponential or in the form of [tex]f(x) = (a)^{x}[/tex] then for x  = 0 value of this exponential function will be f(0) = 1 but as per table f(0) = 0, so the given function is not an exponential function.

Therefore the given function is a linear function.

Linear function is always in the form of y = mx + c

Now f(0) = m×0 + c = 0

c = 0

f(1) = m×1 = 2

m = 2

Now we replace the values of m and c in y = mx + c

The equation will be y = 2x.

Option B. y = 2x is the answer.

the sum of the first [tex]n[/tex] terms of an Arithmetic Sequence is given by:

[tex]S_9=\frac{n(a_1+a_n)}{2}[/tex]

where [tex]n[/tex] is the number of terms,

[tex]a_1[/tex] is the first term of the sequence; and

[tex]a_n[/tex] is the first term of the sequence.

So for [tex]a_n=3n-1[/tex],

[tex]a_1=3(1)-1=2[/tex]

and

[tex]a_9=3(9)-1=26[/tex]

Putting these values in the formula to get:

[tex]S_9=\frac{9(a_1+a_9)}{2}[/tex]

[tex]S_9=\frac{9(2+26)}{2} \\\\S_9=\frac{9}{2} (2+26)[/tex]

First five terms:

[tex]a_1=3(1)-1=2[/tex]

[tex]S_1=\frac{1(2+2)}{2}[/tex]=2

[tex]a_2=3(2)-1=5[/tex]

[tex]S_2=\frac{2(2+5)}{2}[/tex]=7

Rotation matrix = [tex]\begin{bmatrix} -3.96 \\ -1.13 \end{bmatrix}[/tex]

Step-by-step explanation:

Given a vector : [tex]<1 , 4>[/tex] , rotation by [tex]\frac{2\pi}{3}[/tex] radian.

A rotation matrix is a matrix that is used to perform a rotation in Euclidean space.

The standard rotation matrix is given by;

R = [tex]\begin{bmatrix}\cos \theta & -\sin \theta \\ \sin \theta & \cos \theta \end{bmatrix}[/tex]

Then, the matrix of rotation by [tex]\frac{2\pi}{3}[/tex] radian  is:

[tex]\begin{bmatrix}x' \\ y'\end{bmatrix}[/tex] = [tex]\begin{bmatrix}\cos \theta & -\sin \theta \\ \sin \theta & \cos \theta \end{bmatrix}[/tex] [tex]\begin{bmatrix}x \\ y\end{bmatrix}[/tex]

Then; substitute [tex]\theta = 120^{\circ}[/tex]

[tex]\begin{bmatrix}x' \\ y'\end{bmatrix}= \begin{bmatrix}\cos 120^{\circ} & -\sin 120^{\circ} \\ \sin 120^{\circ} & \cos 120^{\circ}\end{bmatrix}\begin{bmatrix}1 \\ 4 \end{bmatrix}[/tex]

or

[tex]\begin{bmatrix}x' \\ y'\end{bmatrix}= \begin{bmatrix} -0.5 & -0.866 \\ 0.866 & -0.5 \end{bmatrix}\begin{bmatrix}1 \\ 4 \end{bmatrix}[/tex]

or

[tex]\begin{bmatrix}x' \\ y'\end{bmatrix}= \begin{bmatrix} -0.5 +4(-0.866) \\ 0.866+4(-0.5)\end{bmatrix}[/tex]

Simplify:

[tex]\begin{bmatrix}x' \\ y'\end{bmatrix} = \begin{bmatrix} -3.96 \\ -1.13 \end{bmatrix}[/tex]

Therefore, the rotation matrix of a given vector is, [tex]\begin{bmatrix} -3.96 \\ -1.13 \end{bmatrix}[/tex]

The matrix that represents the rotation of the vector 1,4 by 2pi/3 radians is : (B) [tex]\left[\begin{array}{ccc}-3.96\\-1.13\\\end{array}\right][/tex]

A matrix can be defined as a rectangular array of numbers table of numbers, symbols, or expressions that are arranged into column and rows.A matrix can take different forms which gave rise to the types of matrices.

Given that standard rotation matrix is expressed as :

[tex]R = \left[\begin{array}{ccc}cos\beta &-sin\beta \\sin\beta &cos\beta \\\end{array}\right][/tex]

therefore the matrix by rotation of [tex]\frac{2\pi }{3}[/tex]

[tex]\left[\begin{array}{ccc}x'\\y'\\\end{array}\right] = \left[\begin{array}{ccc}cos\beta &-sin\beta \\sin\beta &cos\beta \\\end{array}\right] \left[\begin{array}{ccc}x\\y\\\end{array}\right][/tex]

substituting the value of [tex]\beta = 120^o[/tex]

[tex]\left[\begin{array}{ccc}x'\\y'\\\end{array}\right] = \left[\begin{array}{ccc}-0.5 &+4(-0.866) \\0.866 &+4(-0.5) \\\end{array}\right] \left[\begin{array}{ccc}\\\\\end{array}[/tex]

Therefore the rotation of the vector is

[tex]\left[\begin{array}{ccc}-3.96\\-1.13\\\end{array}\right][/tex]

In conclusion, The matrix that represents the rotation of the vector 1,4 by 2pi/3 radians is : (B).

Step-by-step explanation:

Let's convert this to slope-intercept form to interpret the equation easier.

5x - 4y = 12

Subtract 5x from both sides.

-4y = -5x + 12

Divide both sides by -4.

y = 5/4x - 3

Based on this, we know the slope is 5/4 and the y-intercept is (0, -3). When you count the rise over run in the picture and look at the y-intercept, they match.

Answer:

Hey,

your answer is   56cm^2

Answer:

15.4 gallons .

Step-by-step explanation:

The rate of gas used  = 380/14 = 27.14 gallons per gallon.

So for each gallon used  you drive 27.14 miles.

So number of gallons used when travelling 418 miles = 418/27.14

= 15.4 gallons .

At the rate your car consumes gas, you will need 15.4 gallons to drive 418 miles.

The first thing to do here is to find out how many miles you can go with a single gallon of gas.

= Gas used / Number of miles traveled

= 14 / 380

= 0.0368 gallons per mile

Now that you have to drive 418 miles, the amount of gas you will need is:

= Number of miles to travel gas per mile

= 418 x 0.0368

= 15.4 gallons

In conclusion, you will need 15.4 gallons.

Final answer:

To adjust the fruit punch from 50% to 70% juice, Sara needs to add 4 gallons of fruit juice to the existing 6 gallons of punch.

Explanation:

The student is attempting to adjust the concentration of juice in a fruit punch mixture from 50% to 70%. Initially, Sara has 6 gallons of punch which is 50% juice. To find out how much fruit juice should be added to reach a 70% juice mixture, we can use the equation of concentration:

Let the amount of juice to be added be x gallons. The total amount of juice in the mixture would then be 50% of 6 gallons plus x gallons, and the total volume of the mixture would be 6 gallons plus x gallons.

The equation representing the new concentration is:

(3 + x) / (6 + x) = 70/100

To solve for x, multiply both sides by (6 + x) and then by 100 to clear the percentage and denominator:

3 + x = 0.7 * (6 + x)

3 + x = 4.2 + 0.7x

Now, subtract 0.7x from both sides:

3 + 0.3x = 4.2

And then subtract 3 from both sides:

0.3x = 1.2

Divide both sides by 0.3 to solve for x:

x = 4 gallons

Therefore, Sara needs to add 4 gallons of fruit juice to the existing punch to create a mixture that is 70% juice, rounding to the nearest hundredth.

Answer:

y = x + 20

Step-by-step explanation:

Isolate the variable you are solving for, y. Note the equal sign, what you do to one side, you do to the other. Add 20 to both sides

x (+20) = y - 20 (+20)

y = x + 20

y = x + 20 is your answer

Answer: Y= x+20

Step-by-step explanation: x = y-20, you must first add 20 to both sides to get Y on its own. So x+20 = y - 20 + 20, the twenties cancel each other out giving us x+20 = y or y=x+20

Final answer:

The test statistic for the hypothesis test regarding the proportion of veterinary clinics that do not treat large animals is approximately 5.11, calculated using the formula for the test statistic of a proportion.

Explanation:

The student is asking about calculating a test statistic for a hypothesis test concerning the proportion of veterinary clinics that do not treat large animals such as cows and horses. The proportion as per the American Veterinary Medical Association's belief is 0.5, and the survey conducted has resulted in 88 out of 120 clinics stating they do not treat large animals. To find the test statistic, we can use the formula for the test statistic of a proportion:

Test Statistic (Z) = (p - P₀) / √(P₀(1 - P₀)/n), where p is the sample proportion, P₀ is the null hypothesis proportion, and n is the sample size.

In this case:

p = 88/120

P₀ = 0.5 (as per the hypothesis)

n = 120

Substituting these values, we get:

Z = (88/120 - 0.5) / √(0.5 * (1 - 0.5) / 120) = (0.7333 - 0.5) / √(0.25 / 120) = 0.2333 / √(0.0020833) = 0.2333 / 0.04564 ≈ 5.11

Therefore, the test statistic is approximately 5.11, when rounded to two decimal places.

A, B,  C, and E are not polynomials.

A polynomial is an expression involving exponents, constants, and variables, so long as:

You are not dividing by a variable.

You are not raising a variable to a power of a negative number.

You are not raising a variable to a power of a fraction.

You are not taking the root of a variable.

Only one of these satisfies the criteria for a polynomial, and that is D. However, the 2nd term, 0x^2 is an unnecessary term, and would only be included if dividing this polynomial by another polynomial.
