Find the mean of the set of numbers {-9,-8,4,-1}

Answer:

240 degrees.

Step-by-step explanation:

The minute hand passes through  60 minutes ( = 360 degrees) in 1 hour.

In 2/3 hours it passes through 2/3 * 360 =  240 degrees.

The number of degrees moved by the minute hand of a clock in a given amount of time is 240 degrees.

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We have been given that the minute hand of a clock in the given amount of time of 2/3 hour.

The minute hand passes through 60 minutes Or 360 degrees in 1 hour.

In 2/3 hours, it passes through;

2/3 x 360 =  240 degrees.

Therefore, the number of degrees moved by the minute hand of a clock in a given amount of time is 240 degrees.

Pat a) The graph in the attached figure

Part b)  [tex]y=(4/3)x-5[/tex]

The slope is  [tex]m=(4/3)[/tex]

The y-coordinate of the y-intercept is  [tex]b=-5[/tex]

Step-by-step explanation:

Part a) Which line represents the linear equation [tex]-3y=15-4x[/tex]?

To graph the linear equation find the intercepts

we know that

The y-intercept is the value of y when the value of x is equal to zero

so

For x=0

[tex]-3y=15-4(0)[/tex]

[tex]-3y=15[/tex]

[tex]y=-5[/tex]

The y-intercept is the point [tex](0,-5)[/tex]

The x-intercept is the value of x when the value of y is equal to zero

so

For y=0

[tex]-3(0)=15-4x[/tex]

[tex]4x=15[/tex]

[tex]x=15/4=3.75[/tex]

The x-intercept is the point [tex](3.75,0)[/tex]

Plot the intercepts to graph the linear equation

see the attached figure

Part b) Rewritten in slope-intercept form

we know that

The equation of the line into slope intercept form is equal to

[tex]y=mx+b[/tex]

where

m is the slope

b is the y-coordinate of the y-intercept

we have

[tex]-3y=15-4x[/tex]

convert to slope intercept form

isolate the variable y

[tex]3y=4x-15[/tex]

[tex]y=(4/3)x-5[/tex]

The slope is  [tex]m=(4/3)[/tex]

The y-coordinate of the y-intercept is  [tex]b=-5[/tex]

It is considered as discrete data.

Since we know the definition of Discrete which refers to all types of data which take only numerical values.

It is based on counts.

According to question, we have given the exact number of freshmen instead of any range or interval.

Answer:

it increase and by 16.7

Step-by-step explanation:

A Dime is worth 2 nickels which equals 10.

let no of dimes be x

let no of nickles be y

so as per the data mentioned in the question , x=2*y-10

total amount = $2.75 

so total amount should comprise of nickels and dimes

x*dimes + y*nickels = $2.75

x*( 2 nickels)+ y *nickels = $2.75

=> nickles( 2x+y) = $ 2.75

but 20 nickels = 1 dollar

nickles(2x+y) = 2.75*20 nickels

cancelling nickles on both sides

2x+y = 55

already we know that x= 2y-10 

so 2(2y-10) +y= 55

4y-20+y=55

5y -20 =55

So, your answer is 55.

Answer:  15 nickels and 20 dimes

Step-by-step explanation:

Nickels (N) = N and each is worth $0.05

Dimes (D) = 2N - 10 and each is worth $0.10

0.05N + 0.10D = 2.75

0.05N + 0.10(2N - 10) = 2.75

0.05N + 0.20N - 1.00 = 2.75

             0.25N - 1.00 = 2.75

             0.25N           = 3.75

                    N          =   15

D = 2N - 10

   = 2(15) - 10

   =  30  - 10

   =     20

Check:

0.05(55) + 0.10(20) = 2.75

   0.75    +     2.00   = 2.75

            2.75           = 2.75 [tex]\checkmark[/tex]

Step-by-step explanation:

Final answer:

To convert the ratio of 20 ounces to 2 pounds into the simplest form, multiply 2 pounds by the conversion factor of 16 to equal 32 ounces. The fraction 20/32 is then simplified to 5/8, which is the simplest form of the ratio.

Explanation:

To convert the ratio of 20 ounces to 2 pounds into a fraction in simplest form, you must first know the unit equivalence between pounds and ounces, which is 1 pound = 16 ounces. Since we are converting pounds to ounces, we multiply the number of pounds by 16. Therefore, 2 pounds is equivalent to 2 x 16 = 32 ounces. Now, we have a ratio of 20 ounces to 32 ounces, which can be expressed as a fraction 20/32. To simplify, both numbers can be divided by the greatest common divisor (GCD) of 4, resulting in 5/8. Thus, the ratio of 20 ounces to 2 pounds in the simplest form is 5/8.

B. Coefficient is your awnser

11 (if you wanna know how many cups [which i mean by 2/3] it is 1)

Step-by-step explanation:

Well, to start, a cook has 11 7/8 cups of flour, right? Well, if you subtract 11 7/8 by 2/3 you get 11 5/24. As an estimate, you would get just plain 11 because there is three numbers when you estimate, 11, 11 1/2, or 12. 11 5/24 is more closer to 11 (because 1/2 would be 11 12/24, and 12 would be 11 13/24 or more until 12)

Answer:

100

Step-by-step explanation:

.75 will make 99 closer to 100

The rounded-off 99.75 to the nearest whole number will be 100.

To round up or down of tens place then we need to look at the unit place if it is less than 5 then we need to round down and if it is greater than 5 then we need to round up of tens digit.

In order to round to a hundred, we need to look at the tens digit if it is less than 5 then we round down and if it is 5 or greater than 5 then we will round up.

The whole number is the nondecimal number for example 2,5,7.

Given the number 99.75

The whole number around 99.75 are 99 and 100

Now,

100 - 99.75 = 0.25 and 99.75 - 99 = 0.75

Since 0.25 < 0.75

100 will be nearer to 99.75 so it will be the correct answer.

Hence "The rounded-off 99.75 to the nearest whole number will be 100".

Answer:

6, she can buy 6 oranges.

After purchasing 5 apples, Lynne has $4.75 left. Since oranges cost $0.75 each, she can afford to buy a maximum of 6 whole oranges.

The subject of this question is a real-world application of the basic mathematics principle of subtraction and division.

Lynne starts with $8.00 and spends $0.65 per apple for 5 apples, which totals to $3.25. We subtract that sum from the starting amount. $8.00 - $3.25 = $4.75 remains. This remaining money is what Lynne can use to buy oranges, which cost $0.75 each.

To find out the maximum whole number of oranges she can buy, we divide the remaining money by the cost of each orange: $4.75 / $0.75 ≈ 6.33.

Since Lynne can't buy a fraction of an orange, we round down to the nearest whole number. So, Lynne can buy a maximum of 6 oranges.

Answer:

at t=4, the particle is at x = 20

Step-by-step explanation:

This question revolves around velocity and displacement of a particle moving in a straight line (along the x-axis). At t = 0 the particle is at x = 0. The velocity of the particle as function of time is given as;

v(t) = 5

The velocity is thus constant, implying further that the particle has 0 acceleration.

To find the position of the particle at t = 4, we employ integral calculus since displacement is an integral of velocity while velocity is a derivative of displacement.

In short, we shall be integrating the velocity function between t =0 and t = 4 to find its location at t = 4.

[tex]\int\limits^4_0 {5} \, dt[/tex]

The integral of 5 with respect to t is 5t + c but we ignore the constant of integration since we are dealing with a definite integral;

5t

The final step is to substitute t with the limits given;

5(4) - 5(0) = 20

The particle was moving along the x-axis, so its new position would be;

x = 20

A particle moving with constant velocity v(t) = 5m/s on the x-axis starts from x = 0. At t = 4 seconds, using the equation of motion (x = xo + vt), we calculate the particle's position to be x = 20m.

The physics question asked here pertains to motion along a line, known as 1-Dimensional Kinematics. Specifically, we are considering a particle moving with a constant velocity, given by v(t) =5 for any time t greater than, or less than 0.

To find the position of the particle at a given time, we can use one of the basic equations of motion:

x = xo + vt.

As per the problem, the particle starts from position x = 0 at time t = 0, so xo = 0. The velocity, v, is a constant 5m/s.  We can use the provided time, t = 4 seconds, and substitute these values in the equation to get:

x = 0 + 5*4.

Therefore, at t = 4 seconds, the particle is at position x = 20m along the x-axis.
