The mean score is 18.5833 , Mode is 21 and Range is 39 of the given scores.

Mean is the average value of all the given numbers

To calculate the mean we have to add all the values and divide the sum by the numbers of values.

Total of all value = 21+18+3+12+15+21+42+24+31+3+12+21 = 223

No of values = 12

Mean = [tex]\frac{223}{12} =18.58333[/tex]

Mode is the value which comes frequently in data set

In the given data 21 is come three times which is most frequently so Mode is 21.

Range is the difference between the largest number and the smallest number of the given data set.

Largest number of the data set is 42 and smallest number is 3 so the range is 42-3 = 39.

The value of sin(t) in fourth quadrant is  -120/169.

Given that cos(t)= 17

t is in fourth quadrant, so sint<0 and cost>0

So sint = -sqrt(1-cos^2(t))= -sqrt(1-25/169)= - sqrt((169-25)/169)= -12/13

Sin(2t) = 2sin(t)cos(t)= 2*-12/13* 5/13 = -120/169

The general term for the sequences 2, 2/3, 2/9, 2/27, and 2/81 .. is Tₙ = 2/3ⁿ⁻¹.

Given sequence is 2, 2/3, 2/9, 2/27, 2/81 .....

Geometric Progression is also known as a geometric sequence in which each term after the first term is obtained by multiplying the previous one by a constant, non-zero number called the common ratio.

We know that a given sequence is a Geometric progression. So we need to find the common ratio

Here the first term is a = 2

common ratio r = 2/3/2 = 1/3

Now the formula for a geometric sequence for n terms is

Tₙ = a * rⁿ⁻¹

Tₙ = 2 * (1/3)ⁿ⁻¹

Tₙ = 2/3ⁿ⁻¹

Therefore the general term for the sequences 2, 2/3, 2/9, 2/27, and 2/81 .. is Tₙ = 2/3ⁿ⁻¹.

The equation of a line perpendicular to y = -10 + 3x that passes through the point (9,2) is y = -1/3x + 1

The equation of the line is given as

y = -10 + 3x

Rewrite the equation as

y = 3x - 10

A linear equation is represented as

y = mx + c

Where

Slope = m

So, we have

m = 3

The slopes of perpendicular lines are opposite reciprocals

This means that

m2 = -1/m1

So, we have

m = -1/3

Evaluate

m = -1/3

The equation of the perpendicular line is then calculated as

y = m(x - x1) + y1

Where

(x1, y1) = (9, -2)

This gives

y = -1/3(x - 9) - 2

Evaluate

y = -1/3x + 3 - 2

Evaluate the sum and the difference

y = -1/3x + 1

So, the equation of a line perpendicular to y = -10 + 3x that passes through the point (9,2) is y = -1/3x + 1

Hence, the required equation of a line perpendicular to y = -10 + 3x that passes through the point (9,2) is y = -1/3x + 1

The equations that model the situation is 1.50t + 2s = $39

The total amount spent is the sum of the total cost of the tacos and the total cost of soda. The total cost of tacos is the product of the cost of one taco and the number of tacos bought. The total cost of sodas is the product of the cost of one soda and the number of sodas bought.

The mathematical operations that would be used is multiplication and addition. Addition is the process of determining the sum of two or more numbers. The sign used to represent addition is +.

Multiplication is the process of determining the product of two or more numbers. The sign used to represent multiplication is x.

Total amount Xochitl spends = total cost of tacos + total cost of sodas

Step-by-step explanation:

Scale Factor is defined as the ratio of the size of the new image to the size of the old image. The center of dilation is a fixed point in the plane. Based on the scale factor and the center of dilation, the dilation transformation is defined. If the scale factor is more than 1, then the image stretches.

For example, if a square is dilated and the side of the smaller (original) square is 4 units and the side of the dilated square (enlarged) is 12 units, then, in this case, the scale factor will be: 12 ÷ 4 = 3.

Perform a Dilation of 4 on point A (2, 3) which you can see in the picture below. Multiply the coordinates of the original point (2, 3), called the image, by 4. Image's coordinates = (2 * 4, 3 * 4) to get the coordinates of the image (8, 12).

And so if you dilate it with a factor of three, then you're going to want to go three times as far down. So minus three, and three times as far to the left, so you'll go minus six.

The basic formula to find the scale factor of a dilated figure is: Scale factor = Dimension of the new shape ÷ Dimension of the original shape.

The statement which best proves that lines k and m are parallel is: C. Angle 1 is congruent to angle 6 because alternate exterior angles are congruent if two parallel lines are cut by a transversal.

Parallel lines can be defined as two (2) lines that are always the same (equal) distance apart and never meet.

The alternate exterior angle theorem states that when two (2) parallel lines are cut through by a transversal, the alternate exterior angles that are formed are congruent or angles of equal measure.

In this context, we can reasonably infer and logically deduce that the statement which best proves that lines k and m are parallel is angle 1 is congruent to angle 6 because by definition all alternate exterior angles are congruent, if two parallel lines are cut by a transversal.

Step-by-step explanation:

4.635 is larger that 4.6135.

The interest rate of $9000 and $6000 investment are 3.5% and 3% respectively.

let's assume the interest rates X and Y on $9,000 and $6,000 investments.

The $9000 is invested at an interest rate that is 0.5% higher than the $6000.

Therefore,

9000(X) = 6000(Y) + 135

X = Y + 0.005

In canonical form:

9000X - 6000Y = 135

X - Y = 0.005

or X = 0.005 + Y

Then,

9000( 0.005 + Y) - 6000Y = 135

Then Y = 0.3 , therefore X = 0.3

So, X = 3.5% (the rate on $9,000 investment) and;

Y = 3% (the rate on $6,000 investment).

An equation for the line for walnut street is: y = 2x + 1.

The slope intercept form for line is given by;

y = mx + c

where

m = slope

c = y-intercept

As, the two streets chestnut street and walnut street are parallel in a map, their slopes are also equal.

The equation of chestnut is y = 2x-6; comparing with general form;

m = 2.

The coordinates of walnut street is (1, 3) = (x₁, y₁)

Thus, equation is;

(y - y₁) = m(x - x₁)

Put the values.

(y - 3) = 2( x - 1)

simplify,

y - 3 = 2x - 1

y = 2x + 1

Thus, the equation for the walnut street is found as; y = 2x + 1.
