Answer:

1) N = M - L

Step-by-step explanation:

Given equation,

→ L = M - N

Now the value of N will be,

→ L = M - N

→ M - N = L

→ -N = L - M

→ N = -L + M

→ [ N = M - L ]

Hence, value of N is M - L.

Answer: She need 14 visits to reach 90 points

Step-by-step explanation:

Let y be the number of points and v be the number of visits

We will have an equation

y= 2.5v + 55

Now we want to find the number of visits she needs to reach 90 points; we put 90 in the y.

90 = 2.5v +55

Subtracted 55 from both sides

35 = 2.5v

Divided both sides by 2.5

v= 14 visits

So she need 14 visits to reach 90 points

96 minimum sample size required to have 95% confidence that the variance of the sample is within 20% of the variance of the population.

Given that,

We have to determine the minimal sample size required to have 95% confidence that the variance of the sample is within 20% of the variance of the population.

We know that,

Confidence Interval is CI=95%

Variance is σ²=20%

We have

n=(Z/M.E)²

n=(1.96/0.20)²

n=(9.8)²

n=96.04

By subtracting the cost of goods sold form the net sales, the gross profit = $439000.

Gross profit is a financial measure that represents the difference between a company's net sales and the cost of goods sold. It is a key indicator of a company's profitability and can be used to assess the efficiency of the company's operations.

The formula for calculating gross profit is:

Gross profit = net sales - cost of goods sold

Gross profit = net sales - cost of goods sold

Gross profit = $732400 - $293400

Gross profit = $439000

Therefore, the gross profit of the company is $439000.

On solving the provided question, we can say that - Level significance  = 0.05, Z = 1.96, Margin of error= 0.0349

A well-known statistical theory called the null hypothesis asserts that there is no statistical connection between two sets of observable data and measurable phenomena for a given set of observed variables. A null hypothesis is a kind of statistical hypothesis that asserts that a certain collection of observations has no statistical significance. Using sample data, hypotheses are tested to determine their viability. Sometimes known as "zero" and symbolized by H0. A scientific hypothesis is a prediction of what researchers will discover via their investigation. A statistical hypothesis, however, states what a statistician does not anticipate. The null hypothesis is so named because of this.

Answer: x=9, excluded value x≠5

Step-by-step explanation:

1. add 3 to both sides -> 16/x-5 = 4

2. then multiply both sides by x-5 -> 16=4(x-5) -> 16=4x-20

3. add 20 to both sides -> 36=4x

4. divide both sides by 4 to solve for x -> 9=x

the excluded value is whatever would make the denominator of the fraction equal to 0. You can't divide by 0. Therefore in this case, x can't equal 5 because 5-5=0

The required equation of the line is y = 4x + 1.

The Slope-intercept form of a line is given by

Where m is the slope of the line and c is the y-intercept

Note:

The product of slopes of perpendicular lines = -1

Here we have

y = -1/4x + 6 Line (1)  

Here slope of the line m₁ = -1/4

Let y = m₂x + c Line (2)

Assume that Line (2) is the perpendicular line to Line

As we know The product of slope of two perpendicular lines is -1  

=> m₁m₂ = -1        [∵ Line (1) and Line (2) perpendicular lines ]

=> -1/4(m₂) = -1     [ ∵ m₁ = -1/4  ]

=>  m₂ = 4

The line (2) => y = 4x + c  

Given that the line passes through (2, 9)

Answer:

D) six and one third feet

Step-by-step explanation:

To find the total amount of wood that Harry needs, we need to find the total length of the three pieces of wood that are two and three fourths feet long and the total length of the six pieces of wood that are one and one third feet long.

The three pieces of wood that are two and three fourths feet long have a total length of 3 * 2 and 3/4 = 6 and 1/4 feet.

The six pieces of wood that are one and one third feet long have a total length of 6 * 1 and 1/3 = 8 and 2/3 feet.

To find the total length of all the pieces of wood, we need to add the total length of the three pieces that are two and three fourths feet long and the total length of the six pieces that are one and one third feet long. This gives us a total of 6 and 1/4 + 8 and 2/3 = 14 and 7/12 feet.

Therefore, Harry will need a total of 14 and 7/12 feet of wood for the project. This is equivalent to approximately six and one third feet, so the correct answer is d) six and one third feet.

0.003 is the probability that the number of calls among the 25 that involve a fax transmission exceeds the expected number by more than 2 standard deviations

To calculate the probability that the number of calls among the 25 that involve a fax transmission exceeds the expected number by more than 2 standard deviations.The mean is the expected number of calls involving a fax transmission, while the standard deviation is the measure of variability in the distribution. We then use this information to calculate the probability of exceeding the expected number by more than 2 standard deviations, which can be done using the z-score formula. The z-score for values more than 2 standard deviations away from the mean is 2.33, which corresponds to a probability of 0.003. Thus, the probability that the number of calls among the 25 that involve a fax transmission exceeds the expected number by more than 2 standard deviations is 0.003.

To find the equation of the line that passes through the point (1, 2) and is perpendicular to the line y=3x-1, we can first find the slope of the line y=3x-1. The slope of this line is 3, so a line perpendicular to it will have a slope of -1/3. We can then use the point-slope form of the line to write the equation of the line that passes through (1,2) and has a slope of -1/3. The point-slap form of a line is given by y-y₁ = m(x-x₁), where (x₁,y₁) is a point on the line and m is the slope of the line. Plugging in the coordinates of the point (1,2) and the slope -1/3, we get the equation y-2 = -1/3(x-1), which simplifies to y-2 = -x/3 + 1/3. Multiplying both sides of the equation by 3 to get rid of the fractions, we get 3y-6 = -x+1. Finally, we can move all the terms to one side of the equation to get the standard form of the line: 3y-x-5 = 0. Therefore, the equation of the line that passes through the point (1, 2) and is perpendicular to the line y = 3x - 1 is x-3y-5=0, so the correct answer is A.

Y axis: now you do the "jumping" portion of this, so you jump up six units as it's a negative, so now your on (3, 6) (red arrows)

Y: axis: but now you have to move down 1 unit, so you essentially "fall" 1 unit down, (3, 5) (pink arrow)

Y axis:  you have to "jump" 4 units up now, so now your at (3, 9) (green arrows)

First note that for "any vector space V, basis B of V is maximal linearly independent set in V". That is there is no other any linearly independent set which contains more than |B| number of elements on B. Let us consider this statement as 1. Two or greater vectors are stated to be linearly independent if none of them may be written as a linear mixture of the others. On the contrary, if at the least certainly considered one among them may be written as a linear mixture of the others, then they may be stated to be linearly dependent. Now here dimension is d and d<n. Thus maximum number of linearly independent vectors that can draw from the set V1, V2....Vn is d.

Answer:

Large box: 18.5 kg

Small box: 13.75 kg

Step-by-step explanation:

Let  L represent a large box, and S represents a small box

We have the equation

3L + 2S = 83 kg

5L + 6S = 175 kg

We time the first equation by -3

-9L - 6S = - 249 kg

5L + 6S = 175 kg

Now Let's find the large box weighs first

Add both equation and we get

-4L = -74 kg

L = 18.5 kg

Now put 18.5 in for the L to find the weight of the small box

5(18.5) + 6S = 175 kg

92.5 + 6S = 175 kg

6S = 82.5 kg

S = 13.75 kg

Answer:

x as large; y as small

3 large + 2 small = 83    (1st equation)

5 large + 6 small = 175    (2nd equation)

3x + 2y = 83   (multiply by -5)

5x + 6y = 175   (multiply by 3)

-15x - 10y = -415

15x + 18y = 525      (simplify)

8y = 110

y = 13.75       (small box weight)

3x + 2y = 83       (substitute the value of y)

3x + 2(13.75) = 83

3x + 27.5 = 83

3x = 55.5

x = 18.5       (large box weight)

3x + 2y = 83

3(18.5) + 2(13.75) = 83

55.5 + 27.5 = 83

83 = 83          (1st equation is proven right)

5x + 6y = 175

5(18.5) + 6(13.75) = 175

92.5 + 82.5 = 175

175 = 175           (2nd equation is proven right)

therefore, large box weight is 18.5kg and the small box weight is 13.75kg.
