The following systems of equations can be used to find the number of pounds of zucchini that were solds z + c = 108 and 150.32 = 1.69z + 0.99c

A farmer sold 108 pounds of produce

The produce that consisted of z pounds of zucchini and c pounds of cucumbers.

z + c = 108

The farmer sold the zucchini for $1.69 per pound and the cucumbers for $0.99 per pound

He collected a total of $150.32.

Money collected by zucchimi = 1.69 x z = 1.69z

Money collected by cucumbers = 0.99 x c = 0.99c

Total money collected = money collected by zucchini + money collected by cucumbers

150.32 = 1.69z + 0.99c

Therefore, the system of equations is z + c = 108 and 150.32 = 1.69z + 0.99c

Sally and Steve approximately 2.9 hours to paint the room together.

The fundamental concept of Time and Work is the same as it is in all Arithmetic topics, namely the concept of Proportionality. When the amount of work done remains constant, efficiency is inversely proportional to time.

Work Done = Time Spent Work Rate

Work Rate = [tex]\frac{1}{time taken}[/tex].

Time Spent = [tex]\frac{1}{rate of work}[/tex].

If a piece of work is completed in x days, then the work completed in one day = [tex]\frac{1}{x}[/tex].

There are two kinds of questions about time and work. Individuals working alone or in groups with different individuals can be a problem.

efficiencies or there may be issues with combined group efficiency. Now, if a person 'A' completes a specific task in X days, the work completed by 'A' in one day is = [tex]\frac{1}{x}[/tex].

Similarly, if a person 'B' completes a specific task in Y days, then his work completed in one day is =[tex]\frac{1}{y}[/tex].

So, if A and B work collaboratively, their combined work done in one day will be [tex]\frac{1}{x} +\frac{1}{y}[/tex], and they will be able to complete the work in [tex]\frac{xy}{x+y}[/tex] days.

Given:

Sally spends 5 hours painting one room.

Steve spends 7 hours painting one room.

In response to the question

Sally will paint part of the room in one hour = [tex]\frac{1}{5}[/tex] part

Steeve will paint part of the room in one hour = [tex]\frac{1}{7}[/tex] part

Together they will paint =[tex]\frac{5*7}{5+7}[/tex] = [tex]\frac{35}{12}[/tex]part

Step-by-step explanation:

     m₁ =  13

Product of slope of the Perpendicular line m * m₁ = -1

The correlation coefficient of

(a) X1 + X2 and X2 + X3  would be 1/2.

(b) X1 + X2 and X3 + X4 would be 0.

What is the correlation in statistics?

Correlation is a statistical measure (a number) that describes the magnitude and direction of a relationship between two or more variables. A correlation between variables, on the other hand, does not imply that a change in one variable is the cause of a change in the values of the other variable.

(a) X1 + X2 and X2 + X3.

We have

Cov(X1 + X2, X2 + X3) = Cov(X1, X2) + Cov(X1, X3) + Cov(X2, X2) + Cov(X2, X3)

                                    = 0 + 0 + Var(X2) + 0

                                    = 1.

We know that

Var(X1 + X2) = Var(X1) + Var(X2) + 2 Cov(X1, X2) = 1 + 1 + 2 · 0 = 2.

Similarly, Var(X2 + X3) = 0. So the correlation between X1 + X2 and X2 + X3 is

                        [tex]=\frac{Cov(X1+X2, X2+X3)}{\sqrt{Var(X1 + X2) Var(X2 + X3)} }\\\\=\frac{1}{\sqrt{2.2} }\\\\=\frac{1}{2}[/tex]

(b) X1 + X2 and X3 + X4.

Since

Cov(X1 + X2, X3 + X4) = Cov(X1, X3) + Cov(X1, X4) + Cov(X2, X3) + Cov(X2, X4)

                                   = 0 + 0 + 0 + 0

                                   = 0,

the correlation between X1 + X2 and X3 + X4 is 0.

Hence, the correlation coefficient of X1 + X2 and X2 + X3  would be 1/2

The probability that the first card is an ace and the second card is a face card is 1.78% and 12/52 respectively.

What is the probability of cards?

Probability is measured by counting and using basic math, such as addition and division. For example, you can multiply the number of spades in a complete deck (13) by the total number of cards in the deck (52) to get the probability of drawing a spade at random: 13 in 52, or 25%.

If you are dealt two cards successively from a standard 52-card deck, find the probability of getting an ace card on the first card and a face on the second.

you want to draw an ace. There are 4 aces out of the 52 cards in the deck so the probability of drawing an ace = 4/52.

So, the combined probability [tex](\frac{12}{52}) . (\frac{4}{52}) = (\frac{3}{13}) . (\frac{1}{13}) = (\frac{3}{169})[/tex]

= 1.78%.

The probability of a face card on the second draw = 12/52 because there are 12 face cards (J, Q, K x 4 of each) and 52 cards in the deck.

Hence, the probability that the first card is an ace and the second card is a face card is 1.78% and 12/52 respectively.

Answer:

2.552 [tex]\frac{feet}{minute}[/tex]

Step-by-step explanation:

(c) is the correct option. When we subtract w₂ from w₁, we get (2 - 3i).

According to our question, we came to know the values of w₁ and w₂ which are written below:
w₁ = -3i
w₂ = -2

In order to subtract w₂ from w₁, we need to arrange the expression as below:

w₁ - w₂ = -3i - (-2)
Upon opening the bracket, minus(-) will be multiplied by (-2) and it becomes +2.  ∴ - x - = +

Hence,
w₁ - w₂ = -3i + 2

We cannot add -3i with 2 as 'i' referred to as 'iota' is an imaginary number that is used to express complex numbers. Its value is [tex]\sqrt{-1}[/tex]. So, our final solution will be.

w₁ - w₂ =  2 - 3i
