If the fishes are divided to be in tenths, then the total pieces of fishes that would be available would be 1730

How to solve for the pieces of fish

It is assumed that Jorge has 173 fish that he intends to cut up into smaller portions for his dog sled team.

The amount of fish pieces that would remain if Jorge divided each fish into tenths must be determined.

We are aware that there are 10 pieces to every fish.

There are a total of 173 fish available for the dog.

The product of the number of fish that are available and the number of pieces that each fish is divided into results in the total number of fish.

173 * 10

according to money magazine, maryland had the highest mean annual household income of any state in at (time website). assume that annual household income in maryland follows a normal distribution with a mean of and standard deviation of . a. what is the probability that a household in maryland has an annual income of or more (to 4 decimals)?

Answers

The probability that a household in Maryland has an annual income of 100000 or more is 0.2373

Given Data;

Maryland had the greatest mean yearly household income of any state, according to Money magazine (time website). Consider a normal distribution with a mean of 75847 and a standard deviation of 33800 for the annual household income in Maryland.

Population Mean (μ) = 75847

Population Standard Deviation (σ) = 33800

'X' follows a normal distribution with a population mean and population standard deviation.

Here,

X ~ N ( μ = 75847 ,σ = 33800 )

Z =(X - μ)/σ

To get the probability that a household in Maryland has an annual income of 100000 or more.

Now, we have to compute P (X > 100000)

P (X > 100000) = 1 - P( (X-μ)/σ < (100000-75847)/33800 )

                         = 1 - p(z < 0.715 )

                         = 1 - 0.7627

                         = 0.2373

The required probability is 0.2373

Answers

There can be different possible ways in which we can remove the objects and can form possibilities within the rows and columns

What are rows and columns?

Rows and columns are used to properly distinguish categories, classifications, types, etc., when they occur in matrices, spreadsheets, etc. The usage of these words is a bit confusing for most. Rows are a group of cells arranged horizontally to provide uniformity. Columns are a group of cells aligned vertically, and they run from top to bottom. Although the main reason for both rows and columns is to bifurcate groups, categories, and so on,

In the question, It is given that:

There are 16 objects.

and Number of rows = 4;

Number of column = 4;

The task to do is to remove 6, leaving an even number of objects in each row.

So, we can do that in the following manner;

So, we can remove the 2nd object, 4th object, 6th object,8th object,10th object, and 12th object. when we are dealing with rows.

So, we can remove the 2nd object, 4th object, 6th object,8th object,10th object, and 12th object. when we are dealing with the column.

So far, Vivian has 18 signatures, and Kyle has 14. Vivian is collecting signatures at an average rate of 1 per day, whereas Kyle is averaging 3 signatures every day. Assuming that their rate of collection stays the same, eventually the two will have collected the same number of signatures. How long will that take? How many signatures will they both have?

Answers

The number of days it take the same number of signature will be 2 days.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Vivian has 18 signatures, and Kyle has 14.

Vivian is collecting signatures at an average rate of 1 per day, whereas Kyle is averaging 3 signatures every day.

Now,

Since, Vivian has 18 signatures, and Kyle has 14.

And, Vivian is collecting signatures at an average rate of 1 per day, whereas Kyle is averaging 3 signatures every day.

Let number of days it take the same number of signature = x

So, We can formulate;

⇒ 18 + x = 14 + 3x

Solve for x as;

⇒ 18 + x = 14 + 3x

⇒ 18 - 14 = 3x - x

⇒ 4 = 2x

⇒ 2x = 4

⇒ x = 2

Thus, The number of days it take the same number of signature will be 2 days.

Choose the equation that represents the line that passes through the point (6, -3) and has a slope of. 1/2

y=2x-3
y=x+3

Answers

Answer:

The line meeting the criteria is y = (1/2)x + 6 does not match any of the answer options.

Step-by-step explanation:

Let's use the slope-intercept form of a linear equation:  y = mx + b, where m is the slope and b the y-intercept (the value of y when x = 0).  We are given the slope, (1/2), so let's put that into the equation:

   y = (1/2)x + b

It is the value we choose for b that will make the line pass through point (6,-3).  We can determine that value by entering the given point in the equation and then solving for b:

y = (1/2)x + b

-3 = (1/2)*(6) + b for point (6,-3)

-3 = 3 + b

b = -6

The full equation is thus y = (1/2)x + 6

See the attached graph.

===

The `list of options doesn't have an equation that matches this conclusion.  The first two aren't even equations.  Assuming for the moment they are mistyped and should have an "=" sign after the y, we will change the list as follows:

y-2x+6     y=2x+6

y-1x-6       y=1x-6

We get the values when x is -8 y is 62, when y is -73 x is 7 and when x is 3 y is -37 for the linear equation y=-9x-10.

Given that,

The linear equation is y=-9x-10.

We have to fill the table given in the question.

First,

Taking x value is -8

We get y value as,

y=-9(-8)-10      (multiply -9 and -8)

y=72-10           (Subtracting 72 and 10)

y=62

When x is -8 y is 62.

Taking y value is -73

We get x value as,

-73=-9x-10

-73+10=-9x

-63=-9x

63=9x

x=63/9

x=7

When y is -73 x is 7.

Taking x value is 3.

We get y value as,

y=-9(3)-10

y=-27-10

y=-37

When x is 3 y is -37.

Therefore, We get the values when x is -8 y is 62, when y is -73 x is 7 and when x is 3 y is -37 for the linear equation y=-9x-10.

The sum of the two numbers is -34 and their difference is 5. Find the numbers.

Answers

Answer:

y = -19.5, x = -14.5

Step-by-step explanation:

We can form equations from this statement:

x + y = -34

x - y = 5

If we rearrange the second equation, we get:

x - y = 5

x = 5 + y

Then, we substitute this value into the other equation to get the answer.

x + y = -34

5 + y + y = -34

Then solve:

2y + 5 = -34

2y = -39

so, y = -19.5

now we can find x with y:

-19.5 + x = -34

-34 + 19.5 = x

x = - 14.5

Answers

The chance that the call arrived when the switchboard was not completely busy is 0.75.

Probability is a branch of mathematics that studies the likelihood of a random event occurring.

It is given that the switchboard is fully busy for the first 15 seconds, that means it is not busy for the next 15 seconds to 60 seconds

Therefore the probability that calls arrived when the switchboard was not fully busy is

P(15< x < 60) = ∫_15^60▒f(x)dx

= ∫_15^60▒〖1/60 dx〗

=1/60 ∫_15^60▒〖1.dx〗

= 1/60 [ x ]6015

= (60 – 15)/60

Answers

The a-values of the business are classified as follows:

Dog walking and house-sitting: positive because they are represented by increasing functions.Lawn care: negative because it is represented by a concave down parabola.

How to obtain the a-value of a business?

The a-value of a business depends on the behavior of the earning function for these business, as follows:

The a-value is positive if the function is increasing.The a-value is negative if the function has decreasing points.

From the table given by the image at the end of the answer, for the lawn care business, a concave down parabola represents the situation, as the earnings start increasing but then during the 3rd month they start to decrease. Hence, the a-value of the business is negative.

[ ? ]%

Answers

The probability that a worker selected at random makes between $350 and $400 = 0.34134

What is a z score formula?

The standard score represents how far a raw score deviates from or exceeds the mean of the phenomenon being observed or measured. Positive standard scores are assigned to raw scores that are greater than the mean, while negative standard scores are assigned to raw scores that are less than the mean.

By using the z score formula:

z = (x - μ) / σ

Where,

x = raw score

μ = mean

σ = Standard deviation

We are told in the question to find the probability that a worker selected at random makes between $350 and $400

Consider, x1 = 350 and x2= 400 with the mean μ = 400 and standard deviation σ = $50.

z1 = (x1 - μ) / σ = (350-400) / 50 = -1

z2 = (x2 - μ) / σ = (400 - 400) / 50 = (0/50) = 0

From tables, P(z <= -1) = 0.15866

P(z <= 0) = 0.5

Then, the probability would give us, P(-1 ≤ z ≤ 0) =0.5 - 0.15866 = 0.34134

Hence, The probability that a worker selected at random makes between $350 and $400 = 0.34134
