The total amount spent by your friend is $8

The given parameters are:

Represent sandwich with x and carton of milk with y

So, we have

x = 2y

This also means that

y + 2x = 10

Substitute x = 2y in y + 2x = 10

y + 2(2y) = 10

This gives

5y = 10

Divide by 2

y = 2

Recall that:

x = 2y

So, we have

x =2 * 1

x = 2

Your friend's purchase can be represented as:

2y + 3x

This gives

Total = 2 * 1 + 3 * 2

Evaluate

Total = 8

Hence, the amount spent by your friend is $8

Step-by-step explanation:

1*15+3*15=60

a) This refers to the mode = $575

b) This refers to the median = $581

c) This refers to the 86th Percentile = $612

d) This refers to the First Quartile = $552

e) The salary is that is 2 standard deviations below the mean = $529

f) About 36 percent of employee's salaries is above $592

g) $627 is 1.5 standard deviations above the mean

Given data

Mean = $585

Median = $581

Mode = $575

First Quartile = $552

Third Quartile = $605

Standard deviation = $28.

86th Percentile = $612

P64 = $592

a) What is the most common salary? $575

This refers to the mode = $575

b) What salary did half the employee's salaries surpass? $581

This refers to the median = $581

c) About what percent of employee's salaries is below $612?

This refers to the 86th Percentile = $612

d) What percent of the employee's salaries are above $552?

This refers to the First Quartile = $552

e) What salary is 2 standard deviations below the mean?

The mean is given as $585 and the standard deviation is $28

2 standard deviation below the mean is:

= 585 - 2 * 28

= 585 - 56

= $529

f) About what percent of employee's salaries is above $592?

P64 is given as $592 this refers to the percent of employee's salaries that falls under 64%. so the percent above is above 64 is given as:

= 100 - 64

= 36%

g) What salary is 1.5 standard deviations above the mean?

The mean is given as $585 and the standard deviation is $28

1.5 standard deviation below the mean is:

= 585 + 1.5 * 28

= 585 + 42

= $627

Answer: 2 pairs

Step-by-step explanation: You can tell which angles are congruent based on the curved markings. Pairs of congruent angles have matching markings. Since two of the angles are congruent to each other, we can assume that the third angles on the triangles are also congruent to each other, but it is not marked as such. So, there are only two marked pairs of congruent angles.

Explanation:

Consider 2 stocks that either go up, down, or stay unchanged. We'd have a 3 by 3 table to show the 3*3 = 3^2 = 9 different outcomes.

This idea can be extended to 3 stocks to have 3*3*3 = 3^3 = 27 outcomes

4 stocks would have 3^4 = 81 outcomes and so on

Therefore, 9 stocks have 3^9 = 19683 outcomes

Step-by-step explanation:

The year will be 2018, the predicted record of 43.74

1920, the record for a certain race was 45.9 sec.

In 1950, it was 45.0 sec.

Let R(t)= the record in the race and t= the number of years since 1920.

How to calculate slope

The equation of slope of any line can be calculated using the following formula, m = rise/run = tanθ = Δy/Δx = (y2 - y1)/(x2 - x1) where, m is the slope. Δy is the change in y-coordinates.

slope = (45-45.9)/30 = -0.9/30 = -0.03

EQUATION:

R(t)= -0.03t + 45.9

b) The predicted record for 2003

t = 83 in 2003

R(83) = -0.03*83 + 45.9

R(83) = 43.41

The predicted record for 2006

t = 86 in 2006

R(86) = -0.03*86 + 45.9

R(86) = 43.32

C) Solve for t

-.02t + 45.7 = 43.74

-.02t = 43.74 - 45.7

-.02t = -1.96

t = +98

1920 + 98 = 2018, the predicted record of 43.74

This type of equations are called linear equations

The linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution. For example, 2x+3=8 is a linear equation having a single variable in it.

Using translation concepts, it is found that the triangles are congruent, as triangle QRS is the result triangle after a 180º rotation about the origin of triangle MNP.

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s range(involving values of y) or in it’s domain(involving values of x). Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis, or rotations of a degree measure around the origin.

From the vertices of the triangles MNP and QRS, the following transformation was applied:

(x,y) -> (-x,-y).

Which is a 180º rotation about the origin, that is, triangle QRS is the result triangle after a 180º rotation about the origin of triangle MNP.

Rotations do not change the side lengths, only the orientation of the triangle, hence the triangles QRS and MNP are congruent.

The probability of choosing a Kiwi or a coconut  is 14/15.

There has to be another flavor in the bag. The probability of picking the third flavor is 1/15.

There can be 15 candies in the bag. There can be more than one possibility.

Probability calculates the odds that a random event would occur. The odds that the random event happens lie between 0 and 1. The more likely the event is to occur, the closer the probability value is to 1. If the probability value is 0.5, it is equally likely and unlikely that the event would happen or not happen. The sum of all probabilities should add up to 1.

The probability of choosing a Kiwi or a coconut = chances of picking a kiwi + chances of picking a coconut

1/3 + 3/5

(5 + 9) / 15 = 14/15

There has to be another flavor in the bag because the sum of the probabilities of picking a coconut or a kiwi does not add up to 1.

The probability of getting another flavor = 1 - sum of the probabilities of picking a kiwi or a coconut

1 - 14/15

15/15  - 14/15 = 1/15

The total number of candies in the bag would be a multiple of 15. The multiple of a number is the product of the number and another number. The possible number of candies are 15, 30, 45, 60, 75, 90

We can find the square of the distance of the point from the center of the circle using the equation for the circle.

  (x -5)² +(y +3)² = r²

  (3 -5)² +(2 +3)² = 4 +25 = 29 > 25 . . . . use (x, y) = (3, 2) in the equation

The point is farther away from the center than points that are on the circle. The point (3, 2) is an exterior point.

Using relations in a right triangle, it is found that the angle of depression from the satellite to the horizon is of 89.35º.

The relations in a right triangle are given as follows:

First, we consider that:

Hence the sine of the angle is given as follows:

sin(θ) = 4000/175000

θ = arcsin(4000/175000)

θ = 1.31º.

Twice the angle of depression x and θ are supplementary, hence:

2x + 1.31 = 180

2x = 178.69.

x = 178.69/2

x = 89.35º.

The angle of depression from the satellite to the horizon is of 89.35º.

A linear equation written in the slope-intercept form is:

Such that a is the slope, and it tells us how fast the function changes.

Positive slopes mean that the lines go upwards (purple or green in this case)

Negative slopes mean that the lines go downwards (blue or red in this case)

As larger is the slope, more steep is the function (for the cases with positive slope, is the opposite for negative slopes).
