Which interval shows the greatest number of students?

Number of 25 cents coins is  80 and number of 50 cents coins is 20.

Step-by-step explanation:

Given,

A bag contains of total value $ 30.

Number of 25 cent coins is four times that of 50 cent coins.

To find number of 25 cents coin is x

Number of 50 cents coin is y

According to the problem,

[tex]\frac{x}{4} +\frac{y}{2} = 30[/tex] ----- eq 1

x = 4y------ eq 2

Now, we will solve these two equation.

Putting the values of x = 4y in eq 1 we get,

[tex]\frac{4y}{4} +\frac{y}{2} = 30[/tex]

or,  [tex]y +\frac{y}{2} = 30[/tex]

or, [tex]\frac{3y}{2}[/tex] = 30

or, y = 20

So, x = 4×20 = 80

Hence,

Number of 25 cents coins = 80 and number of 50 cents coins = 20

Answer:

Step-by-step explanation:

Let 25 cent coin be A and 50 cent coin be B

Given

Total value of 25 cents coin and 50cents coin is $30

That’s

25A + 50B = 30

Also, 25 cents coin is equal to four times that of 50

So,

A = 4B

We now have

25A + 50B = 30

A = 4B

Substitute 4B for A into the first equation

25(4B) + 50B = 30

25 x 4B + 50B = 30

100B + 50B = 30

150B = 30

Divide both sides by 150 to isolate B

150B/150 = 30/150

B = 1/5

Recall

A = 4B

Therefore

A = 4 x 1/5

= 4/5

Number of 25 cents coin is 4/5 and that of 50 cents coin is 1/5

Answer:

A on edge

The correct dot plot is

A dot plot going from 0 to 6. There are 3 dots above 0, 5 dots above 1, 4 dots above 2, 3 dots above 3, 2 dots above 4, 0 dots above 5, and 1 dot above 6.

Data points are represented as dots on a graph with an x- and y-axis in a dot plot, sometimes referred to as a strip plot or dot chart, which is a straightforward type of data visualisation.

Given:

The dot plot which shows most representative number of pets is

A dot plot going from 0 to 6. There are 3 dots above 0, 5 dots above 1, 4 dots above 2, 3 dots above 3, 2 dots above 4, 0 dots above 5, and 1 dot above 6.

This is because

78.5 * height/3=78.5*12/3=78.5 x 4= 314

Step-by-step explanation:

We know that we have the formula that F = ma

Given

Force (F) = 7.5 N

Acceleration (a) = 15 m/s²

Mass (m) = ?

Now

F = ma

7.5 = m * 15

m = 7.5/ 15

Mass = 0.5 kg

The mass of the football is 500 g.

Step-by-step explanation:

Given,

F = 7.5 N

Acceleration (f) = 15 m/s²

To find the mass (m) of the ball.

Formula

F = mf

According to the problem,

m×15 = 7.5

Explanation:

Since the results are not shown properly, I attach the picture with full question inlcuding the diagram that shows the results correctly.

You need to determine P(burger|fries)

That is the ratio of people that ordered burgers from the set of people that ordered fries (the intersection of the two circles) to the total people who ordered fries (the blue circle, including the intersection of the two circles).

The venn diagram shows that the set of people who ordered fries was 10% + 40% = 50% (the percentage inside the blue circle, including the intersection with the purple circle)

And from that set, the subset of people who also ordered burgers is 40% (the intersection of the two circles).

Thus, the probability that a randomly chosen customer ordered a burger given that they ordered fries is:

       [tex]P(burger\mid fries)=\dfrac{P(burger\cap fries)}{P(fries)}[/tex]

        [tex]{P (burger\mid fries)=\dfrac{40\% }{50\% }=0.80=80\%[/tex]

The probability that a randomly chosen customer ordered a burger given that he ordered fries is 80%.

To determine the probability that a randomly chosen customer ordered a burger given that he ordered fries, the following calculation must be performed:

Therefore, the probability that a randomly chosen customer ordered a burger given that he ordered fries is 80%.

A strong correlation

Step-by-step explanation:

The closer the correlation coefficient is to the number 1 the stronger the correlation is.

The correlation coefficient r = 0.875 indicates a strong correlation coefficient.

A statistical metric known as correlation shows how much two or more variables change in relation to one another.

The given correlation coefficient is r = 0.875.

Since the value of r is greater than 0.7, the correlation is strong.

Hence, the correlation coefficient r = 0.875 indicates a strong correlation coefficient.

Answer:

3927 litres of oil to the nearest litre.

Step-by-step explanation:

The volume of the cylinder = π r^2 h

= π * 100^2 * 250.

When half full the volume is  

1/2 * π  * 100^2 * 250

=  3926991 cm^3     Dividing this by 1000:

= 3927 litres.

A cylindrical tank is half-full of oil.

There are 3928 liters of oil in the tank

Volume of cylinder is teh amount of material the cylinder holds.  Volume is the density of the cylinder.

Volume Formula :

[tex]volume = \pi r^2h[/tex]

Given the radius of the cylinder is 100cm

Height of the cylinder is 250 cm

Substitute all the values inside the formula

[tex]V=\pi (100)^2(250)\\V=2500000\pi[/tex]

Cylinder tank is half full of oil . To find half of the volume , we divide the volume by 2

[tex]V=2500000\pi\\Half - full = \frac{2500000}{2}\pi \\Half-full =3926990.817 cm^3[/tex]

Answer:

Volume: 5200 cubic centimeters

Surface area: 1520 square centimeters

Step-by-step explanation:

Volume = [1/2 x 5 x side x apothem] x height

(The apothem is that little 8 cm mark, the height is 26, the side is 10.)

Plug those values in:

V = 1/2 * 5 * s * a * h

  =  1/2 * 5 * 10 * 8 * 26 = 5200 cubic centimeters

Surface area = 2(base area) + 5(lateral area)

SA = 2(200) + 5(260) = 1520 square centimeters

Answer:

[tex]v = 183 {cm}^{3} to \: the \: nearest \: whole \: number[/tex]

Step-by-step explanation:

Volume of a cone is given as:

[tex]v = \frac{1}{3} \times\pi \times \ {r}^{2} \times h[/tex]

where,

pi = 3.14

r = radius = half of diameter; 10cm/2 = 5cm

h = height = 3cm + 4cm = 7cm

Thus,

[tex]v = \frac{1}{3} \times 3.14cm \times {5}^{2} cm \times 7cm[/tex]

[tex]v = \frac{1}{3} \times 3.14cm \times 25cm \times 7cm[/tex]

[tex]v = \frac{1}{3} \times 549.50 {cm}^{3} [/tex]

[tex]v = \frac{549.50 {cm}^{3} }{3} [/tex]

[tex]v = 183.17 {cm}^{3} [/tex]

[tex]v = 183 {cm}^{3} to \: nearest \: whole \: number[/tex]

Step-by-step explanation:

The value of CT is 13x - 1.

A line segment is defined as a measured path between two places. Line segments can make up any polygon's sides because they have a set length.

The figure given below shows a line segment CT, where the length of line segment CT refers to the distance between its endpoints, C and T.

Given that J is the midpoint of CT

CJ = 8x-5 and JT = 5x+4

C______________J______________T

⇒ CT = CJ + JT

Since J is the midpoint of CT, So CJ = JT

⇒ CT = CJ + JT

Substitute the values of CJ = 8x-5 and JT = 5x+4 in the above equation,

⇒ CT= (8x-5)+(5x+4)

⇒ CT= 8x-5+5x+4

Rearrange the likewise terms, and apply the arithmetics operation,

⇒ CT = 8x + 5x - 5 + 4

⇒ CT = 13x - 1

Hence, the value of CT is 13x - 1.

#SPJ2

Final answer:

To find the length of CT, solve the equation 8x-5 = 5x+4 to find x, then substitute the value of x into either CJ or JT to find the segment's length and double it.

Explanation:

The student is asking a geometry problem where they need to find the length of the segment CT given that J is the midpoint of CT with CJ being 8x-5 and JT being 5x+4. Since J is the midpoint, these two segments are equal in length, thus the equation to solve is 8x-5 = 5x+4.

To find the value of x, follow these steps:

Once x is found, substitute it back into either CJ or JT expression to find the length of one segment. Then, double that length to find CT, as CT is equal to 2 times CJ or 2 times JT.
