Answer:

The Car.

Step-by-step explanation:

We need to find the unit rate for each vehicle to figure out who is traveling faster or slower.

Car: 600/20 = 30 ft per second

Motorcycle: 300/12 = 25 ft per second

Answer:

How do you calculate standard deviation without a data set?

You can calculate from other information.

For example, if you roll a standard die, you’re equally likely to get results 1, 2, 3, 4, 5 or 6. The mean result is 1+2+3+4+5+66=3.5 . The variance is 12+22+32+42+52+626−3.52=916−12.25≈2.9167 . Therefore the standard deviation is 2.9167−−−−−√=1.7078 .

Or suppose you know that the chance that a scratch-off lottery ticket returns some prize is 1 in 10. If you buy 900 tickets, on average you will get 90 that return some prize. The standard deviation of the number is 900×0.1×(1–0.1)−−−−−−−−−−−−−−−√=81−−√=9 .

In many other situations you can calculate standard deviation from the information you have. In other situations you can estimate a subjective standard deviation from what you don’t know. You might look at someone and guess their age at 35, with a subjective standard deviation of 4 years.

Answer:

C=2

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

3C + 4C + -13 = 1

(3C + 4C) + (-13) = 1

Combine like terms.

7C + -13 = 1

Add 13 to both sides.

7C = 14

Divide both sides by 7.

C = 2

Answer:

c=2

Step-by-step explanation:

collect like terms 3c+4c=7c

move the constant to the right and change its sign(-13 becomes 13)

then add 1+13=14

The statement that is correct about the volume of the cone is, a cylinder is exactly 3 times bigger than a cone with the same height and radius. Therefore, the formula for the volume of a cone is 1/3 of the volume of a cylinder with the same height and radius.

If we look carefully at a cylinder and the cone, if both the objects have the same radius, still the volume of both the objects is different, that difference is been created because the cone is gradually decreasing to a point while the cylinder is of the same radius during the entire length.

This makes a difference in the volume of the two objects.

Therefore, the statement that is correct about the volume of the cone is, a cylinder is exactly 3 times bigger than a cone with the same height and radius.

Hence, the formula for the volume of a cone is 1/3 of the volume of a cylinder with the same height and radius.

Step-by-step explanation:

we can work out the third angle

all angles add up to 180

90 + 30 = 120, 180 - 120 = 60

using law of sines

[tex] \frac{x}{ \sin(a) } = \frac{b}{ \sin(b) } [/tex]

where sin(a) = 60, b = 30 and sin(b) = 30

[tex] \frac{x}{sin(60)} = \frac{8}{ \sin(30) } [/tex]

[tex]x = \frac{8}{sin(30)} \times \sin(60) [/tex]

This is the interval, where the open seats increase the same time the time in minutes increases.

From the graph, the open seats increases at the interval (100, 600)

This is the first point where the curve changes its direction from decreasing values to increasing values

From the graph, the curve changes its direction at point (25,100)

Hence, the first meeting ended at 10:25 AM

From the graph, we have:

(x,y) = (5, 700)

Hence, there were 700 open seats at 10:05 AM

At 10:00 AM, we have:

(x,y) = (0,800)

At 10:25 AM, we have:

(x,y) = (25,100)

So, the average rate of change is:

[tex]m = \frac{y_2 -y_1}{x_2 -x_1}[/tex]

This gives

[tex]m = \frac{100 - 800}{25 - 0}[/tex]

[tex]m = \frac{-700}{25 }[/tex]

[tex]m = -28[/tex]

Hence, the average rate of change from 10:00 AM to 10:25 AM is -28 people per minute

Answer:  8

Step-by-step explanation:

distributive property = -18 + 3r = 6

cross river = 3r = 6 + 18

add = 3x = 24

lastly, divide = 8

Answer:

2y -x + 6 = 0

Step-by-step explanation:

Here a equation and a point is given to us and we are interested in finding a equation which is perpendicular to the given equation and passes through the given point .

The given equation is ,

[tex]\sf \longrightarrow 2y + 4x = 12 \\ [/tex]

[tex]\sf \longrightarrow 4x + 2y = 12 [/tex]

Firstly convert this into slope intercept form , to find out the slope of the line.

[tex]\sf \longrightarrow 2y = -4x +12\\ [/tex]

[tex]\sf \longrightarrow y =\dfrac{-4x+12}{2}\\ [/tex]

[tex]\sf \longrightarrow y =\dfrac{-4x}{2}+\dfrac{12}{2}\\ [/tex]

[tex]\sf \longrightarrow \red{ y = -2x + 6 } [/tex]

Now on comparing it to slope intercept form which is y = mx + c , we have ,

And as we know that the product of slopes of two perpendicular lines is -1 . So the slope of the perpendicular line will be negative reciprocal of the slope of the given line. Therefore ,

[tex]\sf \longrightarrow m_{\perp}=\dfrac{-1}{-2}=\red{\dfrac{1}{2}} [/tex]

Now we may use the point slope form of the line to find out the equation of the line using the given point . The point slope form is,

[tex]\sf \longrightarrow y - y_1 = m(x - x_1) [/tex]

Now on substituting the respective values we have,

[tex]\sf \longrightarrow y - 1 = \dfrac{1}{2}(x-8)\\ [/tex]

[tex]\sf \longrightarrow 2(y-1 )= x -8 \\[/tex]

[tex]\sf \longrightarrow 2y -2=x-8\\ [/tex]

[tex]\sf \longrightarrow \underline{\boxed{\bf 2y - x + 6=0}} [/tex]

Answer:

2 2/5 cubic cm

Step-by-step explanation:

to find a volume of a rectangular prism you multiply the length width and height together

so our equation looks like this

3 * (4/3) * (3/5)

we can split this equation up into

[3(4/3)] * 3/5

and do the 3 * (4/3) first

3 * (4/3) is 4 when you cross reduce

then multiply 4 by (3/5) and you get 12/5

12/5 or 2 2/5 is your answer

Answer:

x° = 26.5

Step-by-step explanation:

Each triangle is a right triangle; one angle = 90°, second angle = x° , and the   third angle = 63.5° because the 53° + the two angles adjacent to 53° is will = 180° which is the measure of a straight angle and those two angles are equal because the triangles are congruent by HA ; 180° - 53° =  127° ÷ 2 = 63.5°.

Now each triangle angles = 180° so 90° + x° + 63.5° = 180°; 153.5° + x° = 180;

x° = 180 - 153.5; x° =26.5°
