Answer:

98 small drinks and 57 large drinks.

Explanation:

Let's call x the number of small drinks and y the number of large drinks.

If they sold 155 drinks, we can write the following equation:

x + y = 155

In the same way, they made $265, so

1.25x + 2.50y = 265

Because each small drink cost $1.25 and each large drink cost $2.50.

Now, we can have the following system of equations

x + y = 155

1.25x + 2.50y = 265

Solving the firs equation for y, we get:

x + y - x = 155 - x

y = 155 - x

Replacing this on the second equation:

1.25x + 2.50y = 265

1.25x + 2.50(155 - x) = 265

Then, solving for x, we ge:

1.25x + 2.50(155) - 2.50(x) = 265

1.25x + 387.5 - 2.50x = 265

-1.25x + 387.5 = 265

-1.25x + 387.5 - 387.5 = 265 - 387.5

-1.25x = -122.5

-1.25x/(-1.25) = -122.5/(-1.25)

x = 98

Finally, we can find the value of y replacing x = 98

y = 155 - x

y = 155 - 98

y = 57

Therefore, they sell 98 small drinks and 57 large drinks.

There are various types of equation systems, including linear, non-linear, and multiple or single-variable systems.

A set of two linear equations with two variables is a system of linear equations.

ax + by = C

A set of two or more equations in two or more variables that includes at least one nonlinear equation is referred to as a system of nonlinear equations. A nonlinear equation can be written as ax+by+C≠0 or ax + b y + C ≠0.

The equation for a linear equation in one variable is written as ax+b = 0, where a and b are two integers, and x is a variable. This equation has only one solution.

Ex: ax+b = 0

Answer:

Explanation:

From the information given,

mean = 101

standard deviations = 14

We need to find the number of standard deviations between 73 and the mean.

Number of standard deviations = (73 - 101)/14 = - 28/14 = - 2

It is 2 standard deviations from the mean. According to the empirical rule, 95% of the population lies between 2 standard deviations of the mean. The required area is to the right of 2 standard deviations since we want to find the least score. Thus, the probability of having IQ scores are at least 73 is

Probability of red or green card = 3/5

Number of red cards = 3

Number of blue cards = 6

Number of green cards = 6

Total number of cards = 6 + 6 + 3 = 15

Probability of red or green card = Probability of red card + Probability of green card

Probability of red card = number of red cards/total number of cards

Probability of red card = 3/15

Probability of green card = number of green cards/total number of cards

Probability of green card = 6/15

Probability of red or green card = 3/15 + 6/15

Probability of red or green card = 9/15

In simplest term:

Explanation:

• Car 1 leaves point A at 5:30 p.m., driving due south at an average speed of 35 mph.

• Car 2 leaves point A at 6:30 p.m., driving due north at an average speed of 45 mph.

At 9:30 pm, the time taken by the cars is:

Using the binomial distribution, the probability of no one having done a one time fling is of 0.735 = 73.5%.

The mass density formula for the probability of x successes is:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters of the formula are given as follows:

In the context of this problem, the values of the parameters are as follows:

The probability that no one has done a one time fling is P(X = 0), hence the probability is calculated as follows:

P(X = 0) = (0.95)^6 = 0.735 = 73.5%.

Answer:

m = -2 and n = -3

Explanation

Given the polynomial

x^2 - 5x + 6

Rewrite as x^2 +mx + nx + 6

x^2 - 2x - 3x + 6

Compare

mx = -2x

m = -2

Similarly;

nx = -3x

n = -3

Hence m = -2 and n = -3

To simplify the expression (x-2) +(x+6), you have to follow these steps:

1.Get rid of the parentheses:

(x-2) +(x+6)

x -2 + x + 6

2. Combine like terms:

x + x - 2 + 6

2x + 4

B) The equivalent expression to 3(−4.5b − 2.1) − (6b + 0.6) is - 19.5b - 6.9

A) We want to simplify negative one eighth j plus two thirds minus the expression five thirds j plus nine twelfths. This would be expressed as;

-1/8j + 2/3 - (5/3j + 9/12)

= -1/8j + 2/3 - 5/3j - 9/12

= -1/8j - 5/3j + (2/3 - 9/12)

= (-3j-40j / 24 + (8-9) / 12

= [-⁴³/₂₄j + (-1)]/12

B) The expression equivalent to 3(−4.5b − 2.1) − (6b + 0.6)

Expand the brackets to get;

-13.5b - 6.3 - 6b - 0.6

The sum of the first five terms in this series is 4 14/27.

Fractions are used to depict the components of a whole or group of items. Two components make up a fraction. The numerator is the number that appears at the top of the line. It specifies how many identically sized pieces of the entire event or collection were collected. The denominator is the quantity listed below the line. The total number of identical objects in a collection or the total number of equal sections that the whole is divided into are both displayed. A fraction can be expressed in one of three different ways: as a fraction, a percentage, or a decimal. The first and most popular way to express a fraction is in the form of the letter ab. Here, a and b are referred to as the numerator and denominator, respectively.

The first five terms

|u|=c is equivalent to u = c or u = -c.

Given that c > 0.

i.e., c is a positive number.

Then |u| = c. That is, absolute value of u = c, a positive number.

An absolute value function is defined by,

 |u| = { u   ; if u ≥ 0

        { -u   ; if u < 0

The absolute value of any number, Positive or negative, is always a positive number.

So here |u| = c, with c > 0.

Comparing with the definition of absolute value function, c is either u or -u.

More clearly, c = u, when u ≥ 0 or c = -u , when u < 0.

Hence the value of c depends on u.

Thus,  |u|=c is equivalent to u = c or u = -c.

Robert will paint 310.5 square ft

The side of Robert's barn contains a triangle and a rectangle of which the dimensions are given in the diagram.

If Robert paint one side of the barn, then he needs to paint the triangle as well as the rectangle. So we need to find the area of the triangle and rectangle first.

For the triangle, base = 23 ft

height = 7 ft

Area of the triangle = 1/2 bh

                                 = 1/2 x 7 x 23

                                 = 80.5 square ft.

For the rectangle, length = 23 ft

width = 10 ft

Area of the rectangle = length x width

                                    = 23 x 10

                                    = 230 square ft.

Area Robert needs to paint = Area of the triangle + Area of the rectangel

                                              = 80.5 + 230
