The linear function which represents the line is y = - 3x + 14.

What is Point slope form?

Point slope form is used to represent a straight line using its slope and a point on the line. It means that the equation of a line whose slope is 'm' and which passes through a point (x1, y1) is found using the point-slope form.

Main body:

y - y1 = m (x - x1)

where, (x, y) is a random point on the line and m is the slope of the line.

The given point-slope equation is

y + 1 = - 3 (x - 5)

By further calculation

y + 1 = -3x + 15

y = -3x + 15 - 1

y = -3x + 14

Therefore, the linear function which represents the line is y = - 3x + 14.

Answer:6 times

Step-by-step explanation:12/7 divide 1/4

Answer:  6  times

Step-by-step explanation:  

CuBr is soluble in pure water at a solubility of 0.2583 g/L, while CoBr₂ is soluble at a solubility of 7.50 × 10⁻⁶ g/L

Given,

The equation of reaction as; CuBr₂ → Cu²⁺ + 2Br⁻

In pure water, the Ksp of the solution is 6.27 * 10^-9

Ksp = [Cu²⁺] [Br⁻]²

Ksp = x³

Let's substitute and solve

x³ = 6.27 × 10⁻⁹

x = [tex]\sqrt[3]{6.27 * 10^{-9} }[/tex]

x = 0.0018

The molecular weight of CuBr₂ is 143.5 g/mol

The solubility of CuBr₂ is

0.0018 × 143.5 = 0.2583 g/L

The solubility in 0.0060M of CoBr₂

The equation of dissociation is given as

CoBr₂ → Co²⁺ + 2Br⁻

0.012         0         0

0                0.120   2 * 0.0060 = 0.012M

The dissociation of copper bromide is

CuBr₂ → Cu²⁺ + Br⁻

c                 0         0.012

c - s             s          s + 0.012

The Ksp of this reaction is

[Ksp] = [Co²⁺] [Br⁻]

The Ksp of CuBr₂ = 6.27 × 10⁻⁹

6.27 × 10⁻⁹ = s(s + 0.012)

s + 0.012 = 0.012

0.012 > > > s

6.27 × 10⁻⁹ = s × 0.012

s = 6.27 × 10⁻⁹ / 0.012 = 5.225 × 10⁻⁷ mol / l

Let's convert this into g/L

s =  5.225 × 10⁻⁷ × 143.5 = 7.50 × 10⁻⁶ g/L

Therefore,

The solubility of CuBr in pure water is 0.2583 g/L and the solubility in CoBr₂ is 7.50 × 10⁻⁶ g/L

The number of steps per second that a runner takes is not typically called the stride rate.

Stride rate is a measurement of how frequently a person makes steps when walking or jogging. It is typically expressed in steps per minute and is calculated by dividing the total number of steps taken by the time it takes for each step to be completed. A person is often traveling faster if they have a greater stride rate. Numerous variables, such as a person's height, leg length, and muscular strength, can influence stride pace. The kind of exercise being done and the surface on which a person is walking or jogging might also have an impact. People may assess their development and modify their training plan to increase their speed and efficiency by keeping an eye on their stride rate.

The probability that suits of cards are spades, hearts, and spades is 39/850 or 0.046.

According to the give question.

Three cards are drawn from a standard deck of cards without replacement.

Since,

The total number of cards in a standard deck = 52

Total number of spade cards = 13

Total number of heart cards = 13

Now,

The probability of getting first card as a spade card = 13/52 = 1/4

The probability of getting second card as heart card = 13/(52 -1)     (cards are drawn without replacement)

                                                                                        = 13/51

The probability of getting third card as a spade card = (13 - 1)/52 -2

                                                                                        = 12/50

                                                                                        = 6/25

The value of seaweed height that divides the bottom 30%  from the top 70% is 8.96 cm.

What is a Normal distribution in statistics?

Data in a normal distribution are symmetrically distributed and have no skew. The majority of values cluster around a central region, with values decreasing as one moves away from the center. In a normal distribution, the measures of central tendency (mean, mode, and median) are all the same.

Given data:

X: height of seaweed.

       X~N (μ;σ²)

       μ= 10 cm

       σ= 2 cm

We have to find the value of the variable X that separates the bottom 0.30 of the distribution from the top 0.70

              P(X ≤ x) = 0.30

              P(X ≥ x) = 0.70

Now by using the standard normal distribution,

we have to find the value of Z that separates the bottom 0.30 from the top 0.70 and then use the formula

        Z = (X - μ)/σ

translates the Z value to the corresponding X value.

           P(Z ≤ z) = 0.30

In the body of the table look for the probability of 0.30 and reach the margins to form the Z value. The mean of the distribution is "0" so below 50% of the distribution you'll find negative values.

                  z= -0.52

Now you have to clear the value of X:

        Z= (X - μ)/σ

        X= (Z * σ) + μ

       X = (-0.52 * 2) + 10

         = 8.96

hence, the value of seaweed height that divides the bottom 30%  from the top 70% is 8.96 cm.

Step-by-step explanation:

Using the addition and subtraction operations, we find out that the money left with Camillo is equal to $361.75.

It is given to us that -

The total cost for bread = $48.75

The total cost for peanut butter = $384

and, the total cost for jelly = $192

It is also given to us that Camillo has spent $986. 50.

We have to find out the money he has left.

Firstly, we have to find out the total costs spent by Camillo by adding the costs spent on bread, peanut butter, and jelly.

Total costs = $48.75 + $384 + $192 = $624.75

The total amount that Camillo had with him initially is given by $986. 50.

So, in order to find out the money that Camillo is left with, we have to subtract the total costs spent by Camillo from the initial total amount that Camillo had.

Thus, money left = $986. 50 - $624.75 = $361.75

Therefore using addition and subtraction operations, we find out that the money left with Camillo is equal to $361.75.

The sample mean is a fair estimation of the population mean, according to probability theory. We also observed in our simulations that the means of bigger samples are more likely to be closely grouped around the population mean than the means of smaller samples.

Give two instances and an explanation of what a linear equation is ?

A linear equation in two variables is one that has the form ax + by + c=0, where a, b, and c are real integers and the coefficients of x and y, i.e., a and b, respectively, are not equal to zero. The linear equations 10x+4y = 3 and -x+5y = 2 are two-variable examples.

(a) Let a represent the number of canoes produced. The cost C(x) of producing a canoes is then

C(x) = 20x + 18000

(b) If x represents the number of canoes sold, then the revenue R(x) from selling a canoes will be

R(x) = 80x

(c) The break-even point is the x-value where C(x) = R(x) where the revenue generated from selling a canoes matches the cost of producing a canoes. This will happen when

20x + 18000 =80x → 18,000=60x  →  x=300

When 300 canoes are produced, this business will reach break-even threshold.

They will incur a $24,000 expense and generate a $24,000 profit. Anymore than 300 canoes will result in a profit that outweighs the cost. Anything less than 300 canoes will cause their expenses to outpace their income.
