What is the best description for the graph below

Answers

Answer:

B. The graph decreases everywhere

Step-by-step explanation:

We see a graph going down as x-value increases.

It is not increasing (line shod go up) or constant (horizontal) graph..

Correct choice is B

Answer:

The graph decreases everywhere.

Step-by-step explanation:

As we view the graph, in the x - axis from 0 to 9 the line has came down (decreased). So, we can say that the graph decreases everywhere.

A dot plot with an axis marked from 0 to 10 at increments of 1 is shown. Plot shows 8 dots at 0, 7 dots at 1, 5 dots at 2, 4 dots at 3, 2 dots at 4, and 1 dot at 10.



A)
The mean is equal to the median and the data are symmetric.

B)
The peak is equal to the median and the data are skewed.

C)
The data are skewed and there is an outlier.

D)
The data are symmetric and there is an outlier.

Answers

Answer:

C) The data are skewed and there is an outlier.

Step-by-step explanation:

Its clear from the dot plot that:

There is an outlier at 10, since majority of data are concentrated at 0-4 interval  with only one far away.The data are skewed, since most data concentrated to one side of the median.

So, the correct choice is C

The given information in the dot plot is,

i) An outlier is present at 10.

ii) The data's majority are concentrated at 0 to 4 interval.

iii) 10 is the only one, which is far away.

iv) We confirm that the data are skewed.

v) Because the most data is concentrated in one median's side.

Then the final answer will be,

C) The data are skewed and there is an outlier.

Therefore, option (C) is the answer.

Find the measure of the indicated aces and angles

Answers

Answer:

a=21

b=69

c=42

d=138

Step-by-step explanation:

c is supplementary to d (which is 138), so c=180-138= 42.

angle b is on the edge of the central angle 138, so b is 1/2, therefore, b=69.

angle a is complementary to angle b because any triangle that includes the diameter is a right angle, so angle a=90-69=21.

Answer:

Step-by-step explanation:

This is a right triangle trig problem. Picture a right triangle. The height of the triangle is the height of the lighthouse, your distance from the base of the lighthouse is what we are solving for, and the reference angle is 2 degrees, which is the angle of inclination from where you stand to the top of this lighthouse. We have the reference angle, the side opposite the reference angle, and we are looking for the side adjacent to the reference angle. This is the tangent ratio: the side opposite the reference angle over the side adjacent to the reference angle. We know the measure of the reference angle and we know the value of the side opposite the reference angle. Filling in:

At 2:48, what is the degree measure of the smaller angle formed by the hour and minute hands of a 12 hour clock?

Answers

Answer:

The smaller angle will be "156°".

Step-by-step explanation:

According to the question,

Before 12, the minute hand at 48 minutes:

= [tex]60-48[/tex]

= [tex]12[/tex] (minutes to 12)

So,

= [tex]12 \ minutes+14 \ minutes[/tex]

= [tex]26 \ minutes[/tex]

hence,

The smaller angle will be:

= [tex]26\times 6^{\circ} \ each[/tex]

= [tex]156^{\circ}[/tex]

Answer:

The angle is 204 degree.

Step-by-step explanation:

The angle turned by minute hand in 1 minute is 6 degree

The angle turned by the hour hand in 1 hour is

For the hour hand :

The angle turned in 1 hour = 360/12 = 30degree

At 2 : 00 , the angle covered = 30 x 2 = 60 degree

In each minute the hour hand moves  = 30 degrees / hour  x  1 hour/60 min  

                              = 1/2 degree  

So at 2: 48   the hour hand is at    2*30  + 48 * 1/2 = 84 degrees

For the minute hand:

In each minute it turns = 6 degrees  

So, at 48 minutes the minute hand is at   48 x 6 = 288 degrees

So, the angle between them is 288 - 84 = 204 degrees

4 t-shirts and a hat costs £26.00
A t-shirt and a hat costs £8.00.
How much does a t-shirt cost?
How much does a hat cost?

Answers

T-shirt $4.00
Hat $10.00
A t-shirt and hat is $8.00 you can divide that by 2 and you get 4. So it will be $4.00
$4.00 times 4 =$16.00 for T-Shirt
So that will mean that the hat is $10.00
And $16.00+$10.00=$26.00

That’s what I got so far
I got
T-shirt: £6
Hat: £2
Lets say t-shirts are ‘a’ and hats are ‘b’
4a + b = 26 and a + b = 8
In an equation:
|4a + b =26
|a + b =8
Now I’m canceling the ‘a’ in the equation so I can solve for b
I’m going to multiply the ‘a’ in the bottom by -4 so if I add it to the ‘4a’ it’ll be equal 0
I can’t only multiply the ‘a’, I have to multiply the whole bottom part:
|4a + b =26
-4 |a + b =8
And now:
|4a + b =26
|-4a -4b =-32
We got rid of the a in the equation
4a-4a=0
b-4b=-3b
26-32=-6
-3b=-6
And b=2
Now we’ll go back to the original equation and replace ‘b’ with its value to solve for ‘a’
|4a + 2 =26 ==> 4a=26-2
|a + 2 =8 ==> a=8-2

4a=24
a=6
Therefore, a T-shirt cost £6 and a hat cost £2.

Suggest methods (other than Cartesian Coordinates) of describing the location of points on a plane.

Answers

Answer:

There are two alternatives: (i) Polar coordinate system (a.k.a. Circular coordinate system), (ii) Elliptic coordinate system.

Step-by-step explanation:

There are two alternative ways of describing the location of points on a plane:

(i) Polar coordinate system (a.k.a. Circular coordinate system).

(ii) Elliptic coordinate system.

Now we proceed to explain briefly the characteristic of each option:

Polar coordinate system: [tex](r, \theta)[/tex]

Where:

[tex]r[/tex] - Distance of the point with respect to origin.

[tex]\theta[/tex] - Direction of the vector between origin and point with respect to the +x semiaxis, in sexagesimal degrees.

The formulae for each component in terms of Cartesian coordinates are described below:

[tex]r = \sqrt{x^{2}+y^{2}}[/tex] (1)

[tex]\theta = \tan^{-1} \frac{y}{x}[/tex] (2)

Elliptic coordinate system: [tex](\mu, \nu)[/tex]

Where [tex]\mu[/tex] and [tex]\nu[/tex] are elliptical coordinates.

The formulae for each component in terms of Cartesian coordinates are described below:

[tex]x = a\cdot \cosh \mu \cdot \cos \nu[/tex] (3)

[tex]y = a \cdot \sinh \mu \cdot \sin \nu[/tex] (4)

Where [tex]a[/tex] is the distance between origin and any of the foci along the x axis.
